Gular fig, Cluster fig or Country fig, which is considered sacred, has golden coloured exudate and black bark. It is distributed all over India. Its roots are useful in treating dysentery. The bark is useful as a wash for wounds, highly efficacious in threatened abortions and recommended in uropathy. Powdered leaves mixed with honey are given in vitiated condition of pitta. A decoction of the leaves is a good wash for wounds and ulcers. Tender fruits (figs) are used in vitiated conditions of pitta, diarrhoea, dyspepsia and haemorrhages. The latex is administered in haemorrhoids and diarrhoea (Warrier et al, 1995). The ripe fruits are sweet, cooling and are used in haemoptysis, thirst and vomiting (Nadkarni, 1954; Aiyer et al, 1957; Moos, 1976). Nalpamaradi coconut oil, Candanasava, Valiya Arimedastaila, Dinesavalyadi Kuzhambu, Abhrabhasma, Valiya candanaditaila, etc. are some important preparations using the drug (Sivarajan et al, 1994).

It is a moderate to large-sized spreading laticiferous, deciduous tree without many prominent aerial roots. Leaves are dark green and ovate or elliptic. Fruit receptacles are 2-5cm in diameter, sub- globose or pyriform arranged in large clusters on short leafless branches arising from main trunk or large branches. Figs are smooth or rarely covered with minute soft hairs. When ripe, they are orange, dull reddish or dark crimson. They have a pleasant smell resembling that of cedar apples. The bark is rusty brown with a fairly smooth and soft surface, the thickness varying from 0.5-2cm according to the age of the trunk or bark. Surface is with minute separating flakes of white tissue. Texture is homogeneously leathery (Warrier et al, 1995).

Stem-bark gives gluanol acetate, -sitosterol, leucocyanidin-3-O- -D-glucopyrancoside, leucopelargonidin-3-O- -D-glucopyranoside, leucopelargonidin -3-O- -L-rhamnopyranoside, lupeol, ceryl behenate, lupeol acetate and -amyrin acetate. Stem- bark is hypoglycaemic and anti-protozoal. Gall is CVS active. Bark is tonic and used in rinder pest diseases of cattle. Root is antidysenteric and antidiabetic. Leaf is antibilious. Latex is antidiarrhoeal and used in piles. Bark and syconium is astringent and used in menorrhagia (Husain et al, 1992).

Plaksah is the Ficus species with few branches and many adventitious roots growing downward. It is widely distributed throughout India and in Sri Lanka, S. China, Ryuku Isles and Britain. Plakasah is one of the five ingredients of the group panchvalkala i.e, five barks, the decoction of which is extensively used to clear ulcers and a douche in leucorrhoea in children. This decoction is administered externally and internally with satisfactory results. Plaksah is acclaimed as cooling, astringent, and curative of raktapitta doshas, ulcers, skin diseases, burning sensation, inflammation and oedema. It is found to have good healing property and is used in preparation of oils and ointments for external application in the treatment of ulcers (Aiyer and Kolammal, 1957). The stem-bark is used to prepare Usirasava, Gandhataila, Nalpamaradi taila, Valiya marmagulika, etc. (Sivarajan et al, 1994). The bark and leaves are used in wounds, ulcers, bruises, flatulent colic, hepatopathy, diarrhoea, dysentery, diabetes, hyperdipsia, burning sensation, haemaorrhages, erysipelas, dropsy, ulcerative stomatitis, haemoptysis, psychopathy, leucorrhoea and coporrhagia (Warrier et al,1995) F. microcarpa is a large glabrous evergreen tree with few aerial roots. Leaves are short- petioled, 5-10cm long, 2-6cm wide and apex shortly and bluntly apiculate or slightly emarginate. Main lateral nerves are not very prominent and stipules are lanceolate. Fruit receptacles are sessile and globose occurring in axillary pairs. It is yellowish when ripe without any characteristic smell. Bark is dark grey or brown with a smooth surface except for the lenticels. Outer bark is corky and crustaceous thin and firmly adherent to inner tissue. Inner bark is light and flesh coloured with firbrous texture (Warrier et al, 1995). It is also equated with many other species of the genus. viz. F. Singh and Chunekar, 1972; Kapoor and Mitra, 1979; Sharma, 1983).

The bark contains tannin, wax and saponin. Bark is antibilious. Powdered leaves and bark is found very good in rheumatic headache. The bark and leaves are astringent, refrigerant, acrid and stomachic.

Banyan tree is a laticiferous tree with reddish fruits, which is wound round by aerial adventitious roots that look like many legs. It is found in the Sub-Himalayan tract and Peninsular India. It is also grawn throughout India. It is widely used in treatment of skin diseases with pitta and rakta predominance. Stem-bark, root -bark, aerial roots, leaves, vegetative buds and milky exudate are used in medicine. It improves complexion, cures erysepelas, burning sensation and vaginal disorders, while an infusion of the bark cures dysentery, diarrhoea, leucorrhoea, menorrhagia, nervous disorders and reduces blood sugar in diabetes. A decoction of the vegetative buds in milk is beneficial in haemorrhages. A paste of the leaves is applied externally to abcesses and wounds to promote suppuration, while that of young aerial roots cure pimples. Young twigs when used as a tooth brush strengthen gum and teeth (Nadkarni, 1954; Aiyer and Kolammal, 1957; Mooss,1976). The drug forms an important constituent of formulations like Nalpamaradi Coconut oil, Saribadyasava, Kumkumadi taila, Khadi ra gulika, Valiyacandanadi taila, Candanasava, etc. (Sivarajan et al, 1994). The aerial roots are useful in obstinate vomiting and leucorrhoea and are used in osteomalacia of the limbs. The buds are useful in diarrhoea and dysentery. The latex is useful in neuralgia, rheumatism, lumbago, bruises, nasitis, ulorrhagia, ulitis, odontopathy, haemorrhoids, gonorrhoea, inflammations, cracks of the sole and skin diseases (Warrier et al, 1995).

It is a very large tree up to 30m in height with widely spreading branches bearing many aerial roots functioning as prop roots. Bark is greenish white. Leaves are simple, alternate, arranged often in clusters at the ends of branches. They are stipulate, 10-20cm long and 5-12.5cm broad, broadly elliptic to ovate, entire, coriaceous, strongly 3-7 ribbed from the base. The fruit receptacles are axillary, sessile, seen in pairs globose, brick red when ripe and enclosing male, female and gall flowers. Fruits are small, crustaceous, achenes, enclosed in the common fleshy receptacles. The young bark is somewhat smooth with longitudinal and transverse row of lenticels. In older bark, the lenticels are numerous and closely spaced; outer bark easily flakes off. The fresh cut surface is pink or flesh coloured and exudes plenty of latex. The inner most part of the bark adjoining the wood is nearly white and fibrous (Warrier et al, 1995).

The bark yields flavanoid compounds A, B and C; A and C are identified as different forms of a leucoanthocyanidin and compound B a leucoanthocyanin. All the 3 were effective as hypoglycaemic agents. Leaves give friedelin, -sitosterol, flavonoids- quercetin-3-galactoside and rutin. Heart wood give tiglic acid ester of taraxasterol. Bark is hypoglycemic, tonic, astringent, antidiarrhoeal and antidiabetic. Latex is antirheumatic. Seed is tonic. Leaf is diaphoretic. Root fibre is antigonorrhoeic. Aerial root is used in debility and anaemic dysentery (Husain et al, 1992).

Peepal tree or Sacred fig is a large deciduous tree with few or no aerial roots. It is common throughout India, often planted in the vicinity of the temples. An aqueous extract of the bark has an antibacterial activity against Staphylococcus aureus and Escherichia coli. It is used in the treatment of gonorrhoea, diarrhoea, dysentery, haemorrhoids and gastrohelcosis. A paste of the powdered bark is a good absorbent for inflammatory swellings. It is also good for burns. Leaves and tender shoots have purgative properties and are also recommended for wounds and skin diseases. Fruits are laxative and digestive. The dried fruit pulverized and taken in water cures asthma. Seeds are refrigerant and laxative. The latex is good for neuralgia, inflammations and haemorrhages (Warrier et al, 1995). Decoction of the bark if taken in honey subdues vatarakta (Nadkarni, 1954; Aiyer and Kolammal, 1957; Mooss, 1976; Kurup et al, 1979). The important preparations using the drug are Nalpamaradi taila, Saribadyasava, Candanasava, Karnasulantaka, Valiyamarma gulika etc (Sivarajan et al, 1994). branches bearing long petioled, ovate, cordate shiny leaves. Leaves are bright green, the apex produced into a linear-lanceolate tail about half as long as the main portion of the blade. The receptacles occurring in pairs and are axillary, depressed globose, smooth and purplish when ripe. The bark is grey or ash coloured with thin or membranous flakes and is often covered with crustose lichen patches. The outer bark is not of uniform thickness, the middle bark in sections appear as brownish or light reddish brown. The inner part consists of layers of light yellowish or orange brown granular tissue (Warrier et al, 1995).

Bark gives -sitosterol and its glucoside. Bark is hypoglycaemic. Stem bark is antiprotozoal, anthelmintic and antiviral. Bark is astringent, antigonorrheic, febrifuge, aphrodisiac and antidysenteric. Syconium, leaf and young shoot is purgative (Husain et al, 1992).

Agrotechnology: Ficus species can be cultivated in rocky areas, unused lands, or other wastelands of the farmyard. The plant is vegetatively propagated by stem cuttings. A few species are also seed propagated. Stem cuttings of pencil thickness taken from the branches are to be kept for rooting. Rooted cuttings are to be transplanted to prepared pits. No regular manuring is required. Irrigation is not a must as a plant is hardy. The plant is not attacked by any serious pests or diseases. Bark can be collected after 15 years. Ficus species generally has an economic life span of more than hundred years. Hence bark can be regularly collected from the tree. Root, bark, leaves, fruits and latex form the economic parts (Prasad et al,1995).... ficus

Hin: Sanay, Sana Ka Patt;

Ben: Sonamukhi;

Mal: Sunnamukki, Chonnamukki, Nilavaka;

Tam: Nilavirai, Nilavakai;

Tel: Netatangedu

Importance: Indian Senna or Tinnevelly senna is a shrub very highly esteemed in India for its medicinal value. The leaves are useful in constipation, abdominal disorders, leprosy, skin diseases, leucoderma, splenomegaly, hepatopathy, jaundice, helminthiasis, dyspepsia, cough, bronchitis, typhoid fever, anaemia, tumours and vitiated conditions of pitta and vata (Warrier et al,1994). It is used in Ayurvedic preparations; “Pancha Sakara Churna”, “Shat Sakara Churna” and “Madhu Yastyadi Churna” used for constipation. Its use is widespread in Unani system and some of the important products of this system containing senna are “Itrifal Mulayyin”, “Jawarish Ood Mulayyin”, “Hab Shabyar”, “Sufuf Mulliyin”, “Sharbat Ahmad Shahi”, etc. used as a mild laxative (Thakur et al, 1989).

Distribution: The plant is of Mediterranean origin. It is found in Somalia, Saudi Arabia, parts of Pakistan and Kutch area of Gujarat. It is largely cultivated in Tirunelveli, Ramanathapuram, Madurai and Salem districts of Tamil Nadu.

Botany: The genus Cassia, belonging to the family Caesalpiniaceae, comprises of a number of species, namely,

C. senna Linn. syn. C. angustifolia Vahl.

C. absus Linn.

C. alata Linn.

C. auriculata Linn.

C. burmanni Wight. syn. C. obovata (Linn.) Collad.

C. glauca Lam.

C. javanica Linn.

C. mimosoides Linn.

C. obtusifolia Linn. syn. C. tora Linn.

C. occidentalis Linn.

C. pumila Lam.

C. slamea Lam.

C. acutifolia Delile.

C. sophera Linn.

C. senna is a shrub or undershrub, 60-75cm in height with pale subterete or obtusely angled erect or spreading branches. Leaves are paripinnate. Leaflets are 5-8 in number, ovate-lanceolate and glabrous. Flowers are yellowish, many and arranged in axillary racemes. Fruits are flat legumes, greenish brown to dark brown and nearly smooth (Chopra et al,1980, Warrier et al,1994).

In commerce, the leaves and pods obtained from C. senna are known as “ Tinnevelly Senna” and those from C. acutifolia Delile. as “Alexandrian Senna”. The leaves of C. acutifolia are narrower than C. senna, otherwise both resemble to a large extent (Thakur et al, 1989). All the true Sennas have the portions of their leaves unequally divided. In some kinds the lower part of one side is reduced to little more than a line in breadth, while the other is from a quarter to half an inch in breadth. The drug known under the name of East Indian Senna is nearly free from adulteration; and as its properties appear identical with those of the Alexandrian and the price being less, it probably will supersede it in general practice. Its size and shape readily identify it (Graves, 1996).

Agrotechnology: The plant requires a mild subtropical climate with warm winters which are free from frost for its growth. Semiarid areas with adequate irrigation facilities are ideal for cultivation. Areas having high rainfall, humidity and poor drainage are not suitable. Light or medium loamy soils with adequate drainage and pH varying from 7.0-8.2 are preferable. In South India both summer and winter crops are possible. The plant is propagated by seeds. The seed rate required is 15-20kg/ha. Seeds are sown in October-November (winter rainfed crop) or in February-March (irrigated crop). Higher seed rate is required for unirrigated crop. Seeds are sown in lines 30cm apart. Application of 5-10t of FYM/ha before planting or raising a green manure crop is beneficial. About 40kg N and 25-50kg P2O5/ha applied as basal dressing and 40kg N/ha applied in 2 split dozes as top dressing gave better yield. While the rainfed crop is grown without irrigation, the irrigated crop requires 5-8 light irrigations during the entire growing season. The crop requires 2-3 weedings and hoeings in order to keep it free from weeds. Alternaria alternata causes leaf spot and dieback but the disease is not serious. In North India, the plant is attacked by the larvae of butterfly Catopsilia pyranthe which can be controlled by planting the crop in March-April instead of June-July. Under irrigated conditions, the first crop is obtained after 90 days of planting. The leaves are stripped by hand when they are fully green, thick and bluish-green in colour. The second crop is taken 4 weeks after the first harvest and the third 4-6 weeks after the second one. The last harvest of leaves is done when the entire crop is harvested along with the pods. Yield under irrigated conditions is nearly1.4t of leaves and 150kg pods/ha and under unirrigated conditions is 500-600kg leaves and 80-100kg pods/ha. The leaves are dried in thin layers under shade so as to retain the green colour and the pods are hung for 10-12 days to get dried. The leaves and pods are cleaned, graded and marketed (Husain et al, 1993).

Properties and Activity: Leaves contain glucose, fructose, sucrose and pinnitol. Mucilage consists of galactose, arabinose, rhamnose and galacturonic acid. Leaves also contain sennoside-C(8,8’- diglucoside of rhein-aloe-emodin-dianthrone). Pods contain sennosides A and B, glycoside of anthraquinones rhein and chrysophanic acid. Seeds contain -sitosterol (Husain et al, 1992). Leaves and pods also contain 0.33% -sterol and flavonols-kaempferol, kaempferin, and iso-rhamnetin. Sennoside content of C. acutifolia is higher ranging from 2.5% to 4.5% as compared to C. angustifolia ranging from 1.5 % to 2.5%.

The purgative activity of Senna is attributed to its sennosides. The pods cause lesser griping than the leaves. Leaf and pod is laxative. The leaves are astringent, bitter, sweet, acrid, thermogenic, cathartic, depurative, liver tonic, anthelmintic, cholagogue, expectorant and febrifuge.... indian senna

Glycyrrhiza glabra

Papilionaceae

San: Yashtimadhu Hin: Jathimadh Mal: Irattimadhuram Tam:Athimadhuram

Tel: Yashtimadhukam

Ben: Yashtomadhu Pun:Muleti

Importance: Liquorice or Muleti is a perennial herb or undershrub about 1m high. Its dried peeled or unpeeled underground stems and roots constitute the drug which is an important constituent of all cough and catarrh syrups, throat lozenges and pastilles. This has been used in medicine for more than 4000 years. Hippocrates (400 BC) mentioned its use as a remedy for ulcers and quenching of thirst. Dioscorides, the father of Greek medicine described this drug in detail and considered it useful for maintaining shape of arteries and in burning stomach, trouble of liver and kidney, scabies, healing of wounds and as a remedy for eye diseases. It has been used in Arab system of medicine for more than 600 years from where it has been adopted to modern medicine (Gibson, 1978).

The commercial name of the dried rhizome and root of the plant is liquorice which is used as flavouring agent and the taste coorigent in pharmaceutical and confectionery industries and its products are widely reported to be useful in ulcer therapy. Glycyrrhizin, a triterpene glucoside, is the principal constituent of G. glabra which is 50 times sweeter than sugar.

Distribution: Liquorice is native to Mediterranean region, South Europe and Middle East. It is widely distributed in Spain, Italy, Greece, Syria, Iraq, Afghanistan, Turkey, parts of USSR and China. However its cultivation is limited to small areas in USSR, UK, and USA. In India, it grows in Punjab and Jammu and Kashmir. Semi arid areas of Haryana, Rajasthan and Gujarath states are suitable for the cultivation of Liquorice. However, its commercial cultivation has not yet been possible and the domestic requirement is largely met through imports.

Botany: Glycyrrhiza glabra Linn. belongs to the family Papilionaceae. The word Glycyrrhiza is of Greek origin meaning ‘sweet’ and glabra means ‘smooth’ which refers to smooth fruit of the species. This is a tall perennial, self pollinated herb or undershrub about 1m high with long cylindrical burrowing rootstock and horizontal creeping stolons which reach 1.5-1.8m in length. Leaves are alternate, pinnate with 9-17 leaflets. Leaflets are yellowish-green, 2.5-5cm long, ovate and obtuse. Flowers are pale blue arranged in a raceme and 1.25cm long. Calyx is glandular and pubescent. The pods are glabrous, red to brown having 3-4 seeds. Rhizome is soft, flexible and fibrous with light yellow colour and a characteristic sweet taste.

Agrotechnology: This plant thrives well in subtropical areas with very warm summers and cool winters with a rainfall not exceeding 500mm. Semi -arid and arid areas in subtropical zones are not suitable for the cultivation of this crop. It does not tolerate high humidity and waterlogged conditions. Well drained light loam soils which are rich in calcium and magnesium with slightly alkaline pH and free from stones are ideal for this crop. There are a number of varieties of this crop among which Spanish, Russian and Persian liquorice are quite common. Commercial varieties are Typica, Regel and Herd. This is propagated by seed, but usually multiplied vegetatively either through crown cuttings or stolon pieces. In the case of crown cuttings, 10-15cm long crown pieces with 2-3 buds are planted vertically at a distance of 0.6-0.7m in rows 1-1.5m apart. However, most of the liquorice is propagated through stolon pieces of the above size planted horizontally, preferably on ridges during spring at the same distance as above. Rapid clonal propagation is also possible by tissue culture technique. Murashige and Skoog’s medium supplemented with 6-benzylaminopurine and indole-3-acetic acid favoured multiple shoot production without any intervening callus phase. These regenerated plantlets can be transferred to earthen pots in the glass house and after a brief hardening phase, these are transplanted in the field with a high rate (90-95%) of survival. This plant normally does not require much fertilizers but in deficient soils, it is better to apply 10-15 tonnes FYM per hectare before planting. The field should be immediately irrigated after planting in spring and after the crop has sprouted, it requires very little irrigation. Space between the rows should be kept free from weeds. Short term vegetables like carrot or cabbage can be planted between the rows for additional income. In order to produce good rhizome, flowering shoots are clipped. No serious disease except leaf spot caused by Cercospora cavarae has been reported in this crop. Roots are ready for harvesting after 3-4 years. The root is dug when the top has dried during autumn (November- December). A trench 60cm deep is dug along the ridges and the entire root is lifted. Broken parts of the root left in the soil, sprout again and give another crop after 2-3 years. Thus liquorice once planted properly can be harvested for 10-15 years.

Postharvest technology: Harvested roots are cut into pieces of 15-20cm long and 1-2cm in diameter. They are washed and dried upto 6-8% moisture in the sun and shade alternately which reduces the weight by 50%. The average yield of dried roots varies from 1-3 tonnes per hectare depending on the variety, soil and climatic conditions.

Properties and activity: Roots gave a number of compounds the most important bieng a glucoside, glycyrrhizin which gave glycyrrhetinic acid on enzyme hydrolysis. Root also contains flavans, flavones, iso-flavanoes and coumarins including a 4-methyl coumarin, liqcoumarin, glabridin, glabrene, 4’-0-methyl and 3’-methoxyglabridin, formononetin, salicylic acid, 0-acetyl salicylic acid which has been isolated first time from nature, hispaglabridins A and B and 4’0- methylglabridin.On hydrolysis it also gave two molecules of d-glucuronic acid, each linked with 1-2 linkage to 3-hydroxyl of the sapogenin (Elgamal et al, 1969) Glycyrrhizin is antidiuretic, antiinflammatory, expectorant, antiulcerous, antihistamine. Glycyrrhizic acid is antiviral. The roots are emetic, tonic, diuretic, demulcent, mild laxative, aphrodisiac, trichogenous, expectorant, emmenagogue, alexipharmic, alterant and intellect promoting.... liquorice

Tam: Nervalam, Sevalamkottai

Tel: Nepala

Importance: Purging croton or croton oil plant, a small evergreen tree with separate male and female flowers, is one among the seven poisons described in Ayurveda. The drug is well known for its drastic purgative property. The drug is found to be useful in ascites, anasarca, cold, cough, asthma, constipation, calculus, dropsy, fever and enlargement of the abdominal viscera. The seed paste is a good application for skin diseases, painful swellings and alopacia. The seed-oil is useful in chronic bronchitis, laryngeal affections, arthritis and lock jaw. Misraka-sneham is an important preparation using the drug (Nadkarni, 1954; Dey, 1980; Sharma, 1983).

Distribution: It is distributed throughout North India. It is cultivated in Assam, West Bengal and South India.

Botany: Croton tiglium Linn. belongs to the family Euphorbiaceae. It is a small evergreen tree, 4.5-6.0m in height with ash coloured smooth bark and young shoots sprinkled with stellate hairs. Leaves are oblong to ovate-lanceolate, obtuse or rounded at the 2-glanded box, acuminate, membraneous, yellowish green and minutely toothed. Flowers are small, unisexual, males on slender pedicels, females larger and on short thick pedicels. Fruits are ovoid or oblong trigonous capsules. Seeds are smooth, testa black and enclosing reddish brown oily endosperm (Warrier et al,1994). Other species belonging to the genus Croton are as follows:

C. aromaticus Linn. C. caudatus Geisel C. jouera Roxb.

C. malabaricus Bedd.

C. oblongifolius Roxb.

C. polyandrus Roxb. syn. Baliospermum montanum Muell-Arg.

C. reticulatus(Chopra et al, 1980)

Agrotechnology: The plant is propagated by seeds. Seeds are to be sown on seedbeds and about 2 months old seedlings are used for transplanting. Pits of size 50cm cube are to be taken at 3m spacing and filled with dried cowdung, sand and topsoil and formed into a mound. The seedlings are to be planted on these mounds. Irrigation during summer months is beneficial. Application of organic manure after every 6 months is desirable. Weeding is to be carried out one month after transplanting. The plant is not attacked by any serious pests or diseases. Fruits are formed at the end of first year. Fruits when ripen and start to crack are to be collected, dried in sun, then the outer shell is removed and again dried for one day before marketing (Prasad et al,1997).

Properties and activity: Oil contains phorbol myristate acetate (Husain et al, 1992). Seeds contain upto 20% protein and 30-50% lipids. Iso-guanine-D-ribose (crotoniside) and saccharose were isolated from the seeds. In fractionation of croton oil, liquid-liquid distribution procedures proved to be the separation tools of choice. The per hydrogenated parent hydrocarbon of phorbol is a perhydrocyclopropabenzulene called tigliane and phorbol is 1, 1a , 1b , 4, 4a, 7a , 7b, 8, 9, 9a-decahydro-4a , 7 , 9 , 9a - tetrahydroxy-3-(hydroxymethyl)-1, 1, 6, 8 tetramethyl-5-H-cyclopropa[3,4] benz [1.2-e]azulen-5- one. Phorbol, a tetracylic diterpene with a 5, 7, 6 and 3- membered ring has 6 oxygen functions. Phorbol accounts for 3.4% and 4- deoxy- 4 - phorbol for 0.29% of the weight of croton oil. Twenty- five phorbol-12, 13-diesters have been detected (Hecker et al, 1974). A toxin croton 1, mol. wt 72,000 has been isolated from the seeds (Lin et al, 1978).

Phorbol myristate acetate activates nitroblue tetrazolium reduction in human polymorphs. Seed and oil is purgative, rubefacient and anti-dote for snakebite. The seeds and oil are acrid, bitter, thermogenic, emollient, drastic purgative, digestive, carminative, anthelmintic, antiinflammatory, vermifuge, deterent, diaphoretic, expectorant, vesicant, irritant and rubefacient.... purging croton

Importance: Ambrette, also popularly known as musk or Muskmallow, is an erect annual herb which yields musk-like scented seeds and woos everybody through its sensuous musky fragrance. Every part of this medicinal plant is used in one or the other way. Seeds are effective aphrodisiac and antispasmodic, and used in tonics. They check vomiting and cure diseases due to kapha and vata and are useful in treating intestinal disorders, urinary discharge, nervous disorders, hysteria, skin diseases, snake bites, pruritus, leucoderma and general debility. Flower infusion is contraceptive. The leaves and roots are used for gonorrhoea and to treat boils and swellings.

Ambrette oil of commerce is extracted from the seeds and is used in perfumery, flavouring, cosmetic and agarbathi industries. The essential oil is employed in non-alcoholic beverages, ice-creams, candies and baked foods. The aromatic concrete and absolute, extracted from seeds are used as base material for preparing high grade perfumes, scents and cosmetics. It is also known for exalting, amplifying and diffusing effects it imparts to perfumes. It blends well with rose, neroli, and sandal wood oil and aliphatic aldehydes.

The flowers are in great demand for making ‘zarda’ a flavoured tobacco in India. The seeds are mixed with tea and coffee for flavour. The seed is rich in essential amino acids and is used as cattle or poultry feed. The stem bark yields a good quality fibre. Seeds are used to protect woollen garments against moth and it imparts a musky odour to sachets, hair powder, panmasala and incense. Its tender shoots are used in soups, green pods as vegetable and seed husk in flower arrangements. From perfumes to panmasalas and tonics, it is the musky musk all the way. In addition to internal consumption, its seeds are exported to Canada, France and UK because of its diversified uses (Srinivasan et al, 1997).

Distribution: The musk plant is a native of India and it grows in the tropical subtropical and hilly regions of the country; particularly in the states of Maharashta, Gujarat, Madhyapresh, Tamil Nadu and Kerala. More than 50 collections of the plant are maintained by the National Bureau of Plant Genetic Resources (NBPGR), New Delhi and its regional station in Akola, Maharashtra.

Botany: Abelmoschus moschatus Medicus syn. Hibiscus abelmoshus Linn. belongs to Family Malvaceae. Muskmallow is an erect annual or biennial hirsute or hispid herb of 60-180 cm height. The leaves are simple polymorphous, usually palmately 3-7 lobed; lobes narrow, acute or oblong-ovate, crenate, serrate or irregularly toothed, hairy on both surfaces. Flowers are large and bright yellow with purple centre. Fruits are fulvous, hairy and capsular. Seeds are many, subreniform, black or greyish - brown and musk scented (Husain et al, 1992).

Agrotechnology: Ambrette is a hardy plant which can be grown in varied climate under tropical and subtropical conditions. It can be grown both as a rainfed crop and as an irrigated crop. It grows on well drained loamy and sandy loam soils. Loamy soils with neutral pH and plenty of organic matter are ideal for its cultivation.

Musk of propagated through seeds. The optimum time of sowing is June-July with pre- monsoon showers. The land is prepared well by ploughing, harrowing and levelling. Well decomposed FYM or compost is incorporated into the soil at 10 - 15 t/ha. Ridges and furrows are formed giving a spacing of 60 - 100 cm. Seed rate is 2-3 kg/ha. Seeds are soaked in water before sowing for 24 hours. Two to three seeds are sown per hole at 60 cm spacing on one side of the ridge at a depth of 1 cm and covered with a pinch of sand or loose soil. It takes 5-7 days for proper germination. After germination, extra seedlings are thinned out leaving one healthy growing plant per hole within 20 days. Fertilisers are applied at 120:40:40 kg N, P2O5, K2O/ha generally. However, a dose 160:80:80 kg/ha is recommended for best yields of seed and oil. Phosphorus is applied fully as basal. N and K are applied in 3 equal doses at planting, 2 and 4 months after planting. Fertilizers are applied 10 cm away from the plants. For irrigated crop, field is irrigated soon after sowing. Irrigation is given twice a week during the initial period and once a week thereafter. The field is kept weed free by regular weeding during the growing period (Farooqi and Khan, 1991).

Musk plants suffer from pests like spider mites, fruit bores and leaf eating caterpillars. Diseases like powdery mildew and wilt are also observed on the plant. Spider mites and powdery mildew are controlled by spraying 30g wettable sulphur in 10 litres of water. Pod borers can be controlled by spraying 20ml oxydemeton methyl in 10 litres of water.

The crop starts flowering about 75 days after sowing. The flowers set into fruits in 3-4 days and the pods take nearly a month to mature. Flowering and fruit setting extends from October to April. Harvesting is arduous. Fruits have to be plucked as soon as they attain black colour; otherwise, they split and seeds scatter. Therefore, weekly collection of pods is necessary and in all 20-25 pluckings may be required as it is a 170-180 days duration crop. The fruits are further dried and threshed to separate seeds. The seed yield is 1-1.5 /ha

Postharvest technology:. The oil is extracted from seed by steam distillation followed by solvent extraction.

The concrete of solvent extraction is further extracted with alcohol to get the absolute, that is, the alcohol soluble volatile concentrate.

Properties and activity: The fatty oil of seeds contain phospholipids as 2 - cephalin, phosphatidylserine and its plasmalogen and phosphatidyl choline plasmalogen. Absolute contains farnesol and ambrettolic acid lactone. - sitosterol and its - d - glucosides are isolated from leaves. Petals contain -sitosterol, flavonoid myricetin and its glucoside. Anthocyanins like cyanidin - 3 - sambubioside and cyanidin - 3 - glucoside are present in the flowers. (Chopra and Nayar, 1980) Seeds are aphrodisiac, antispasmodic, diuretic, demulcent, antiseptic, stomachic, tonic, carminative, antihysteric, antidiarrhoeal, ophthalmic, cardiac and antivenum.... ambrette

Agrotechnology: Cucurbits can be successfully grown during January-March and September- December. For the rainfed crop, sowing can also be started after the receipt of the first few showers.

Pits of 60cm diameter and 30-45cm depth are to be taken at the desired spacing. Well rotten FYM or vegetable mixture is to be mixed with topsoil in the pit and seeds are to be sown at 4-5/pit. Unhealthy plants are to be removed after 2 weeks and retained 2-3 plants/pit. FYM is to be applied at 20-25t/ha as basal dose along with half dose of N (35kg/ha) and full dose of P (25kg) and K (25kg). The remaining dose of N (35kg) can be applied in 2 equal split doses at fortnightly intervals. During the initial stages of growth, irrigation is to be given at an interval of 3-4 days and at alternate days during flowering and fruiting periods. For trailing cucumber, pumpkin and melon, dried twigs are to be spread on the ground. Bitter gourd, bottle gourd, snake gourd and ash gourd are to be trailed on Pandals. Weeding and raking of the soil are to be conducted at the time of fertilizer application. Earthing up may be done during rainy season. The most dreaded pest of cucurbits is fruit flies which can be controlled by using fruit traps, covering the fruits with polythene, cloth or paper bags, removal and destruction of affected fruits and lastly spraying with Carbaryl or Malathion 0. 2% suspension containing sugar or jaggery at 10g/l at fortnightly intervals after fruit set initiation. During rainy season, downy mildew and mosaic diseases are severe in cucurbits. The former can be checked by spraying Mancozeb 0.2%. The spread of mosaic can be checked by controlling the vectors using Dimethoate or Phosphamidon 0.05% and destruction of affected plants and collateral hosts. Harvesting to be done at least 10 days after insecticide or fungicide application (KAU,1996).... cucurbits

Curcuma spp.

Zingiberaceae

The genus Curcuma belonging to the family Zingiberaceae comprises of a number of species which are medicinally very important. Among them, the most important species are described below.

1. C. amada Roxb.

English: Mango ginger San: Amrardrakam, Karpuraharida Hin: Ama -haldi

Mal: Mangainchi

Tam: Mankayinci

Tel: Mamidi Allam

Mango ginger is cultivated in Gujarat and found wild in parts of West Bengal, U. P, Karnataka and Tamil Nadu. It is a rhizomatous aromatic herb with a leafy tuft and 60-90cm in height. Leaves are long, petiolate, oblong-lanceolate, tapering at both ends, glabrous and green on both sides. Flowers are white or pale yellow, arranged in spikes in the centre of tuft of the leaves. Lip is semi -elliptic, yellow, 3-lobbed with the mid lobe emarginate. The rhizomes are useful in vitiated conditions of pitta, anorexia, dyspepsia, flatulence, colic, bruises, wounds, chronic ulcers, skin diseases, pruritus, fever, constipations, strangury, hiccough, cough, bronchitis, sprains, gout, halitosis, otalgia and inflammations (Warrier et al, 1994). The fresh root possesses the smell of green mango and hence the name mango ginger. The rhizomes are used externally in the form of paste as an application for bruises and skin diseases generally combined with other medicines. Tubers rubbed with the leaf- juice of Caesalpinia bonduc is given for worms (Nadkarni, 1982).

The essential oil contains -pinene, -and -curcumene, camphor, cuminyl alcohol, myristic acid and turmerone. Car-3-ene and cis-ocimene contribute the characteristic mango odour of the rhizome. Rhizome is CNS active, hypothermic and it shows potentiation of amphetamine toxicity. Tuber is trypsin inhibitor and is effective against Vibrio cholerae (Husain et al, 1992). The rhizomes are bitter, sweet sour, aromatic, cooling, appetiser, carminative, digestive, stomachic, demulcent, vulnerary, febrifuge, alexertic, aphrodisiac, laxative, diurectic, expectorant, antiinflammatory and antipyretic (Warrier et al, 1994).

Wild turmeric or Cochin turmeric or Yellow zeodoary is found wild throughout India and cultivated in Bengal and Kerala. It is a perennial tuberous herb with annulate, aromatic yellow rhizome which is internally orange-red in colour. Leaves are elliptic or lanceolate- oblong, caudate-acuminate, 30-60cm long, petioles as long or even longer, bracts ovate, recurved, more or less tinged with red or pink. Flowers are pink, lip yellow, obovate, deflexed, sub-entire or obscurely three lobed. Fruits are dehiscent, globose, 3-valved capsules. Rhizomes are used in combination with astringents and aromatics for bruises, sprains, hiccough, bronchitis, cough, leucoderma and skin eruptions (Warrier et al, 1994). The rhizomes have an agreeable fragrant smell and yield a yellow colouring matter like turmeric, and the fresh root has a camphoraceous odour. The dried rhizome is used as a carminative and aromatic adjunctant to other medicines (Nadkarni, 1998).

Essential oil contains -and - -curcumene, d-camphene and p-methoxy cinnamic acid. The colouring matter is curcumin. Numerous sesquiterpenoids of germacrone and guaiane skeletons have been identified recently. Rhizome has effect on respiration. It is spasmolytic and shows antagonism of amphetamine hyperactivity. Rhizome is an anti-dote for snakebite and carminative (Husain et al, 1992).

Turmeric is cultivated all over India, particularly in W. Bengal, T. N and Maharashtra. It is a perennial herb, 60-90cm in height, with a short stem and tufts of erect leaves. Rhizome is cylindric, ovoid, orange coloured and branched. Leaves are simple, very large, petiole as long as the blade, oblong-lanceolate, tapering to the base upto 45cm long. Flowers are pale yellow, arranged in spikes concealed by the sheathing petioles and flowering bracts are pale green (Warrier et al, 1994). Turmeric occupies an important position in the life of Indian people as it forms an integral part of the rituals, ceremonies and cuisine. Due to the strong antiseptic properties, turmeric has been used as a remedy for all kinds of poisonous affections, ulcers and wounds. It gives good complexion to the skin and so it is applied to face as a depilatory and facial tonic. The drug cures diseases due to morbid vata, pitta and kapha, diabetes, eye diseases, ulcers, oedema, anaemia, anorexia, leprosy and scrofula. It purifies blood by destroying the pathogenic organisms. A paste of turmeric alone, or combined with a paste of neem (Azadirachta indica) leaves, is used to cure ringworm, obstinate itching, eczema and other parasitic skin diseases and in chicken pox and small pox. The drug is also useful in cold, cough, bronchitis, conjunctivitis and liver affections (Nadkarni, 1954; Kurup et al,1979; Kolammal, 1979). The rhizome is the officinal part and is an important ingredient of formulations like Nalpamaradi taila, Jatyadi taila, Narayana gula, etc. (Sivarajan et al, 1994).

Turmeric paste mixed with a little limejuice and saltpetre and applied hot is a popular application to sprains and bruises. In smallpox and chickenpox, a coating of turmeric is applied to facilitate the process of scabbing. The smoke produced by sprinkling powdered turmeric over burnt charcoal will relieve scorpion sting when the part affected is exposed to the smoke for a few minutes. Turmeric and alum powder in the proportion of 1:20 is blown into the ear in chronic otorrhoea (Nadkarni, 1998). “Haridra Khand”, a compound containing powdered turmeric, sugar and many other ingredients is a well-known preparation for cold, cough and flu, and for skin diseases. In Unani system, roasted turmeric is an ingredient of “Hab Narkachur”, used as antidysenteric for children (Thakur et al, 1989).

Essential oil contains ar-turmerone, and ar-curcumene as ma jor constituents. Some of the other compounds are -and -pinene, sabinene, myrcene, -terpinene, limonene, p- cymene, perillyl alcohol, turmerone, eugenol, iso-eugenol, eugenol methyl ether and iso- eugenol methyl ether. Curcumin and related compounds have also been reported as major constituents of the rhizomes. Recently a number of sesquiterpenes have been reported from C. longa, viz., the sesquiterpenoids of germacrane, bisabolane and guainane skeletons (Husain et al, 1992). The study of sesquiterpenes has revealed a new compound curlone (Kisoy et al, 1983). The crystalline colouring matter curcumin (0. 6%) is diferuloyl methane (Mathews et al, 1980). Stigmasterol, cholestrol, -sitosterol and fatty acids, mainly straight chain dienoic acids are reported (Moon et al, 1977). Curcumin, the colouring agent and major constituent of C. longa, is said to possess local as well as systemic antiinflammatory property which has been found to compare favourably with phenylbutazone (Srimal and Dhawan, 1973). An extract of the crude drug ‘akon’ containing the rhizomes exhibited intensive preventive activity against carbon tetrachloride induced liver injury invivo and invitro. The liver protecting effects of some analogs of ferulic acid and p-coumaric acid, probable metabolites of the curcuminoids have been also evaluated (Kiso et al, 1983). Curcumin is antiinflammatory. Rhizome is antiprotozoal, spasmolytic, CNS active, antiparasitic, antispasmodic, antibacterial, antiarthritic, anthelmintic, carminative, antiperiodic, emo llient, anodyne, laxative, diruretic, expectorant, alterative, alexertive, febrifuge, opthalmic and tonic.

4. C. zedoaria (Berg.) Rosc. syn. C. zerumbet Roxb; Amomum zedoaria

Christm.vEng: Round zedoary; San: Kachura, Shati;

Tel: Kacheramu

The round zedoary or Zerumbet is mostly found in India and S. E. Asia. The plant has 4-6 leaves with 20-60cm long lamina. The leaf lami na is oblong-lanceolate, finely acuminate and glabrous on both the surfaces. Flower stalk is 20-25cm long, emerging before the leaves. Flowers are yellow, while the flowering bract is green tinged with red. Calyx is 8mm long, corolla tube is twice as long as the calyx. Capsule is ovoid, trigonous, thin smooth and bursting irregularly. Tubers are palmately branched and camphoraceous (Thakur et al, 1989). The identity of the plant sources of the drug Karcura is a matter of debate. There is difference of opinion among men of Ayurveda, as to whether Sati and Karcura are the same drug or different. Many authors consider them different and equate Sati with Hedychium spicatum Smith. and Karcura with C. zedoaria, both belonging to Zingiberaceae (Kurup et al,1979; Chunekar 1982; Sharma, 1983). Some others treat them to be the same and equate it with C. zedoaria (Kirtikar and Basu, 1918; Vaidya, 1936; Nadkarni, 1954; Kapoor and Mitra, 1979). However, the source of Karcura in Kerala in the recent times has been Kaempferia galanga of the same family. The rhizome of C. zedoaria is used as appetiser and tonic, particularly prescribed to ladies after childbirth. In case of cold, a decoction of long pepper (Piper longum), cinnamon (Cinnamomum verum), zedoary and honey is given. In Ayurveda it is an ingredient of “Braticityadi kwatha”, used in high fever (Thakur et al, 1989). Root is useful in flatulence and dyspepsia, and as a corrector of purgatives. Fresh root checks leucorrhoeal and gonorrhoeal discharges. Root powder is a good substitute for many foreign foods for infants. For worms, the juice from the tubers is given to children. Juice of the leaves is given in dropsy (Nadkarni, 1982). It is an odoriferous ingredient of the cosmetics used for the cure of chronic skin diseases caused by impure or deranged blood (Nadkarni, 1998).

Essential oil from rhizomes contains -pinene, d-camphene, cineole, d-camphor, sesquiterpenes and sesquiterpene alcohols (Husain et al, 1992). The novel sesquiterpenoids which have been isolated and characterised are cuzerenone, epi-cuzerenone, iso- furanogermerene, curcumadiol, curcumol, curcumenol, iso-curcumenol, procurcumenol, dehydrocurdione (Hikino et al, 1968, 1971, 1972), germacrone-4, 5-epoxide, germacrone, germacrone furanodienone, curcumenol, iso-curcumenol, curcumanolides A and B and curcumenone (Shiobara et al, 1985). The starch left after the extraction is purified and sold as a commodity of cottage industry in West-Bengal under the name ‘Shoti’ (Rao et al, 1928). Ethyl-p methoxy-cinnamate has been isolated from the alcoholic extract of the plant (Gupta et al, 1976). Rhizome is stomachic, diuretic, and carminative and gastrointestinal stimulant.

Other important species of Curcuma genus are

C. angustifolia Roxb. (Vellakoova)

C. caesia Roxb. (Black ginger)

C. leucorhiza Roxb.

C. pseudomontana Grah.

C. rubescens Roxb.

Agrotechnology: Curcuma species are tropical herbs and can be grown on different types of soils both under irrigated and rainfed conditions. Rich loamy soils having good drainage are ideal for the crop. The plant is propagated by whole or split mother rhizomes. Well developed, healthy and disease free rhizomes are to be selected. Rhizomes are to be treated with copper oxychloride fungicides and stored in cool, dry place or earthen pits plastered with mud and cowdung. The best season of planting is during April with the receipt of pre-monsoon showers. The land is to be prepared to a fine tilth during February-March. On receipt of pre- monsoon showers in April, beds of size 3x1.2m with a spacing of 40cm between beds are to be prepared. Small pits are to be taken in the beds in rows with a spacing of 25-40cm.

Finger rhizomes are to be planted flat with buds facing upwards and covered with soil or dry powdered cattle ma nure. The crop is to be mulched immediately after planting and 50 days after first mulching. Cattle manure or compost is to be applied as basal dose at 20-40t/ha at the time of land preparation or by spreading over the beds after planting. Application of NPK fertilizers is beneficial and found to increase the yield considerably. Weeding is to be done twice at 60 and 120 days after planting, depending upon weed intensity. Earthing up is to be done after 60 days. No major incidence of pest or disease is noticed in this crop. Leaf blotch and leaf spot can be controlled by spraying Bordeaux mixture or 0.2% Mancozeb. Shoot borers can be controlled by spraying 0.05% Dimethoate or 0.025% Quinalphos. Time of harvest usually extends from January-March. Harvesting is generally done at about 7-10 months after planting depending upon the species and variety. Harvested rhizomes are to be cleaned of mud and other materials adhering to them. Good fingers separated are to be used for curing (KAU, 1996).... curcuma

Datura metel

Solanaceae

San: Dhustura Hin.: Kaladhatura

Ben: Dhatura Mal: Ummam Kan; Dattura

Tam: Vellummattai

Tel: Tellavummetta

Importance: Downy datura or thorn apple is an erect branched under shrub whose intoxicating and narcotic properties have been made use of by man from ancient time. The plant and fruit are spasmolytic, anticancerous and anthelmintic. Leaves and seeds are inhaled in whooping cough, asthma and other respiratory diseases. Root, leaf and seed are febrifuge, antidiarrhoeal, anticatarrhal and are used in insanity, cerebral complications and skin diseases. Leaf is antitumour, antirheumatic and vermicide. Flower is antiasthamatic, anaesthetic and is employed in swellings and eruptions on face. Fruit juice is used in earache and seed decoction in ophthalmia. For the rheumatic swellings of joints, lumbago, sciatica and neuralgia, warm leaf smeared with an oil is used as a bandage or sometimes the leaf is made into a poultice and applied. The root boiled with milk is used in insanity. It is also an ingredient in the ayurvedic preparation Kanakasva used in bronchial troubles, and the Unani formulations “Roghan dhatura” used as a massage oil for the paralysed part. The alkaloids of pharmaceutical interest present in the plant are hyoscyamine, hyoscine and meteloidine. Datura is the chief commercial source of hyoscine available from natural source. Hyoscine, in the form of hyoscine hydrobromide, is used as a pre-anaesthetic in surgery, child birth, ophthalmology and prevention of motion sickness. It is also employed in the relief of withdrawal symptoms in morphine and alcoholic addiction, paralysis agitans, post- encephaletic parkinsonianism and to allay sexual excitement. Hyoscyamine and its salt hyoscyamine sulphate and hyoscyamine hydrobromide are used in delerium, tremour, menia and parkinsonianism (Kaul and Singh, (1995).

Distribution: Datura is distributed throughout the world, particularly the warmer regions. Datura stramonium is indigenous to India. Out of 15 species reported from different parts of the world, only 10 are known to occur in India. They are found commonly in wastelands, gardens and roadsides. They are distributed in rich localities under semi -arid and arid regions of Punjab, Haryana, Rajastan, and Gujarat; the Central Plateau of Andhra Pradesh and Maharastra and the southern peninsular region of Tamil Nadu. Datura innoxia is indigenous to Mexico and is distributed in Latin American countries. A wealth of genetic stock on genotypes and varieties are maintained in several research institutes in Germany, Bulgaria, USSR and Poland.

Botany: The genus Datura, belonging to the family solanaceae, consists of annual and perennial herbs, shrubs and trees. Three species,viz, Datura metel Linn., D. stramonium Linn. and D. innoxia Mill. are medicinally important. D. innoxia mill. and D. metel Linn. (var. alba, and var, fastuosa) are the choice drug plants, rich in hyoscine. D. metel Linn. is the most common in India. The names, D. metel Linn., D. fastuosa Linn., D. alba Nees., D. fastuosa Linn. var. alba (Nees) C.B. Clarke and D. metel Linn. var. fastuosa (Linn.) Safford are synonymously used by many workers. Two varieties are often noted in D. metel Linn., namely the white flowered var. alba and purple flowered var. fastuosa. D. metel Linn. is an erect succulent branched undershrub divaricate often purplish branches and ovate pubescent leaves which are oblique at the base of lamina. Flowers are large, solitary, short pedicelled, purplish outside and white inside. Fruits are sub-globose capsules covered all over with numerous, fleshy prickles, irregularly breaking when mature. Seeds are numerous, smooth, yellowish brown. (warrier et al, 1994).

Agrotechnology: Datura grows well in a wide range of climate from tropical to temperate conditions.

The plant thrives best in areas of low rainfall where winter and monsoon rains are followed by long dry periods. Areas with annual rainfall below 1000mm with mean temperature of 10-15oC in winter and 27 - 28oC in May-June are ideal. The crop cannot stand frost, high rainfall or high temperature in the plains in May-June. It grows on majority of soils, however, alkaline or neutral clay loam soil or those tending to saline-alkaline reaction rich in organic matter are ideal for vigorous growth. The clayey, acidic, water-logged or moisture deficient soils do not suit this crop.

The plant is propagated by seeds but it is characterised by poor and often erratic seed germination which can be improved either by leaching out the inhibitor from the seeds or by alternate freezing and thawing of seeds. The optimum season for raising the crop is Rabi in tropical and subtropical areas while Kharif in temperate areas. The seeds can be broadcast - sown or seedlings can be raised in nursery and then transplanted. Seed rate is 7-8 kg/ha for broadcasting and 2-3 kg/ha. for transplanting. The field is ploughed and disced adequately to produce fine seed bed. In the case of direct seeding, seeds are drilled in rows taken 45-60 cm apart. The plants are thinned to keep a spacing of 30-45 cm at the time of first weeding. In the case of transplanting 4-6 weeks old seedlings are planted at 45-60 x 30-45 cm spacing. The field should be irrigated immediately after sowing or planting if soil moisture is inadequate. Thereafter 3-4 irrigations may be given if sufficient rainfall is not received. Application of organic manure at 10-15 t/ha and fertilisers at 60:40:40 kg N, P2O5 and K2O/ha is recommended for the crop for better growth and yield N may be applied in 3-4 equal split doses at planting and after each weeding which is required 2-3 times during the growing season. Application of micronutrients is reported to improve the alkaloid contents. No major insect pest is known to attack this crop. However, leaf spot, wilt and mosaic diseases cause damage to this crop. Leaf spot is caused by Alternaria tennuissima (Nees) Wiltshire and characterised by brown round to oval spots, becoming necrotic at later stage which leads to withering and dropping of leaves. Wilt is caused by Sclerotium rolfsii Sace; it starts with dropping of leaves and finally wilting of the entire plant. Root and foot wilt, caused by Corticium solani, appears as damping off of seedlings and mature plants. Datura distortion mosaic is characterised by yellowing of the veins followed by inward rolling and distortion of leaves with a reduction in plant size. For reducing the impact of these diseases, field sanitation, use of resistant varieties, crop rotation for 3-4 years and fungicide application should be resorted to. For the purpose of leaf and top, harvesting is done as soon as flowering starts. Entire top containing leaves and twigs is cut, dried in shade and stored in gunny bags. For seed and fruit, fully grown fruits, still green are picked 2-3 times before final harvest when the entire plant is cut from the base and dried in the open. The dried fruits are then thrashed with a stick to separate the seeds. The seed yield is 1-1.5 t/ha. (Husain, 1993; Kaul and Singh, 1995)

Properties and activity: The alkaloids hyoscyamine and hyoscine (scopolamine) and meteloidine are found in all parts of the plant. The total alkaloid content is 0.26 - 0.42 % Fruits contain daturaolone and daturadiol while roots contain additionally ditigloyloxy tropane derivatives, tigloidine, apohyoscine, norhyoscine, norhyocyamine, cusiohygrine and tropine. Other alkaloids isolated from the plant are apohyoscyamine, DL-scopolamine, normeteloidine, tigloylputrescine, scopine, nortigloidine, tropine, psuedo valeroidine, fastudine, fastunine, fastusinine, 7-hydroxy-3, 6-ditigloyloxytropane (2) datura nolone and fastusic acid. The physiological effects of hyoscyamine are qualitatively the same as those of its recemic derivative atropine. This is relatively more active in its paralysing affect on nerve endings and less active in its stimulant action on the central nervous system. The sedative and hypnotic action of hyoscyamine is weaker than that of hyoscine. Atropine has a stimulant action on the central nervous system and depresses the nerve endings to the secretary glands and plain muscles. The plant or the different alkaloids have narcotic, anthelmintic, spasmolytic anaesthetic, sedative, ophthalmic, anticancerous, antitumour, antirheumatic, antiasthmatic, antidiarrhoeal and anticatarrhal activities.

Commiphora mukul

Burseraceae

San: Gugulu, Mahisaksah, Koushikaha, Devadhupa

Hin: Gugal Mal:Gulgulu Tam,

Tel: Gukkulu

Kan: Guggul

Ben: Guggul

Importance: Indian bdellium is a small, armed, deciduous tree from the bark of which gets an aromatic gum resin, the ‘Guggul’ of commerce. It is a versatile indigenous drug claimed by ayurvedists to be highly effective in the treatment of rheumatism, obesity, neurological and urinary disorders, tonsillitis, arthritis and a few other diseases. The fumes from burning guggul are recommended in hay- fever, chronic bronchitis and phytises.

The price of guggulu gum has increased ten fold in ten years or so, indicating the increase in its use as well as decrease in natural plant stand. It has been listed as a threatened plant by Botanical Survey of India (Dalal, 1995) and is included in the Red Data Book (IUCN) and over exploited species in the country (Billare,1989).

Distribution: The center of origin of Commiphora spp. is believed to be Africa and Asia. It is a widely adapted plant well distributed in arid regions of Africa (Somalia, Kenya and Ethiopia in north east and Madagascar, Zimbabwe, Botswana, Zaire in south west Africa), Arabian peninsula (Yemen, Saudi Arabia and Oman). Different species of Commiphora are distributed in Rajasthan, Gujarat, Maharashtra and Karnataka states of India and Sind and Baluchistan provinces of Pakistan (Tajuddin et al, 1994). In India, the main commercial source of gum guggul is Rajasthan and Gujarat.

Botany: The genus Commiphora of family Burseraceae comprises about 185 species. Most of them occur in Africa, Saudi Arabia and adjoining countries. In India only four species have been reported. They are C. mukul(Hook. ex Stocks) Engl. syn. Balsamodendron mukul (Hook. ex Stocks), C. wightii (Arnott) Bhandari, C.stocksiana Engl., C. berryi and C.agallocha Engl.

In early studies about the flora of India, the ‘guggul’ plant was known as Commiphora mukul(Hook. ex Stocks) Engl. or Balsamodendron mukul (Hook. ex Stocks). It was renamed as C. roxburghii by Santapau in 1962. According to Bhandari the correct Latin name of the species is C. wightii(Arnott) Bhandari, since the specific name ‘wightii’ was published in 1839, prior to ‘roxburghi’ in 1848 (Dalal and Patel, 1995).

C. mukul is a small tree upto 3-4m height with spinescent branching. Stem is brownish or pale yellow with ash colored bark peeling off in flakes. Young parts are glandular and pubescent. Leaves are alternate, 1-3 foliate, obovate, leathery and serrate (sometimes only towards the apex). Lateral leaflets when present only less than half the size of the terminal ones. Flowers small, brownish red, with short pedicel seen in fascicles of 2-3. Calyx campanulate, glandular, hairy and 4-5 lobed. Corolla with brownish red, broadly linear petals reflexed at apex. Stamens 8-10, alternatively long and short. Ovary oblong, ovoid and stigma bifid. Fruit is a drupe and red when ripe, ovate in shape with 2-3 celled stones. The chromosome number 2n= 26 (Warrier et al, 1994; Tajuddin et al, 1994).

Agrotechnology: Guggal being a plant of arid zone thrives well in arid- subtropical to tropical climate.

The rainfall may average between 100mm and 500mm while air temperature may vary between 40 C in summer and 3 C during winter. Maximum relative humidity prevails during rainy season (83% in the morning and 48% in the evening).Wind velocity remains between 20-25 km/hour during the year is good. Though they prefer hard gypseous soil, they are found over sandy to silt loam soils, poor in organic matter but rich in several other minerals in arid tracks of western India (Tajuddin et al, 1994).

Plants are propagated both by vegetatively and seeds. Plants are best raised from stem cuttings from the semi woody (old) branch. For this purpose one metre long woody stem of 10mm thickness is selected and the cut end is treated with IBA or NAA and planted in a well manured nursery bed during June-July months; the beds should be given light irrigation periodically. The cuttings initiate sprouting in 10-15 days and grow into good green sprout in 10-12 months. These rooted plants are suitable for planting in the fields during the next rainy season. The cuttings give 80-94% sprouting usually. Air layering has also been successfully attempted and protocol for meristem culture is available in literature. Seed germination is very poor (5%) but seedling produce healthier plants which withstand high velocity winds.

The rooted cuttings are planted in a well laid-out fields during rainy season. Pits of size 0.5m cube are dug out at 3-4 m spacing in rows and given FYM and filler soil of the pit is treated with BHC (10%) or aldrin (5%) to protect the new plants from white ants damage. Fertilizer trials have shown little response except due to low level of N fertilization. Removal of side branches and low level of irrigation supports a good growth of these plants. The plantation does not require much weeding and hoeing. But the soil around the bushes be pulverised twice in a year to increase their growth and given urea or ammonium sulphate at 25- 50g per bush at a time and irrigated. Dalal et al (1989) reported that cercospora leaf spot was noticed on all the cultures. Bacterial leaf blight was also noticed to attack the cultures. A leaf eating caterpillar (Euproctis lanata Walker) attack guggal, though not seriously. White fly (Bemisia tabaci) is observed to suck sap of leaves and such leaves become yellowish and eventually drop. These can be effectively controlled by using suitable insecticide.

Stem or branch having maximum diameter of about 5cm at place of incision, irrespective of age is tapped. The necrotic patch on the bark is peeled off with a sharp knife and Bordeaux paste is applied to the exposed (peeled off) surface of the stem or branch. A prick chisel of about 3cm width is used to make bark- deep incisions and while incising the bark, the chisel is held at an acute angle so that scooped suspension present on the body of the chisel flows towards the blade of the chisel and a small quantity of suspension flows inside the incised bark. If tapping is successful, gum exudation ensures after about 15-20 days from the date of incision and continues for nearly 30-45 days. The exuded gum slides down the stem or branch, and eventually drops on the ground and gets soiled. A piece of polythene sheet can be pouched around the place of incision to collect gum. Alternatively, a polythene sheet can be spread on the ground to collect exuded gum. A maximum of about 500g of gum has been obtained from a plant (Dalal, 1995).

Post harvest technology: The best grade of guggul is collected from thick branches of tree. These lumps of guggul are translucent. Second grade guggul is usually mixed with bark, sand and is dull coloured guggul. Third grade guggul is usually collected from the ground which is mixed with sand, stones and other foreign matter. The final grading is done after getting cleansed material. Inferior grades are improved by sprinkling castor oil over the heaps of the guggul which impart it a shining appearance (Tajuddin et al, 1994).

Properties and activity: The gum resin contains guggul sterons Z and E, guggul sterols I-V, two diterpenoids- a terpene hydrocarbon named cembreneA and a diterpene alcohol- mukulol, -camphrone and cembrene, long chain aliphatic tetrols- octadecan-1,2,3,4-tetrol, eicosan-1,2,3,4-tetrol and nonadecan-1,2,3,4-tetrol. Major components from essential oil of gum resin are myrcene and dimyrcene. Plant without leaves, flowers and fruits contains myricyl alcohol, -sitosterol and fifteen aminoacids.

Piper longum

Piperaceae: San: Pippali;

Hin, Ben, Pun: Piplamul; Kan, Mal:Thippali ;

Tam: Thippili; Mar: Pimpli;

Tel: Pipppaloo; Ass: Piplu.

Introduction: Long pepper is a slender aromatic climber whose spike is widely used in ayurvedic and unani systems of medicine particularly for diseases of respiratory tract. Pipalarishta, Pippalyasava, Panchakola, Pippalayadilauha, and Lavana bhaskar churan are common ayurvedic preparations made out of the dry spikes of female types. Ittrifal fauladi, Angaruya-i-kabir and Majun khadar are well known unani preparations of long pepper. Its roots also have several medicinal uses. The root is useful in bronchitis, stomach ache, diseases of spleen and tumours. Fruit is useful in vata and kapha, asthma, bronchitis, abdominal complaints, fever, leucoderma, urinary discharges, tumours, piles, insomnia and tuberculosis. Root and fruit are used in gout and lumbago. The infusion of root is prescribed after parturition to induce the expulsion of placenta. The root and fruit decoction are used in acute and chronic bronchitis and cough. It contains the alkaloid piperine which has diverse pharmacological activities, including nerve depressant and antagonistic effect on electro- shock and chemo -shock seizures as well as muscular incoordination.

Distribution: The plant is a native of Indo-Malaya region. It was very early introduced to Europe and was highly regarded as a flavour ingredient by the Romans. The Greek name “Peperi”, the Latin “Piper” and the English “Pepper” were derived from the Sanskrit name “Pippali”. It grows wild in the tropical rain forests of India, Nepal, Indonesia, Malaysia, Sri lanka, Rhio, Timor and the Philippines. In India, it is seen in Assam, West Bengal, Uttar Pradesh, Madhya Pradesh, Maharashtra, Kerala, Karnataka.and Tamil Nadu. It is also cultivated in Bengal, Chirapunchi area of Assam, Akola-Amravati region of Maharashtra, Anamalai hills of Tamil Nadu, Orissa, Uduppi and Mangalore regions of Karnataka. Bulk of Indian long pepper comes from its wild growth in Assam, Shillong and West Bengal, supplemented by imports from Sri Lanka and Indonesia (Viswanathan,1995)

Botany: Piper longum Linn. is a member of Piperaceae family. The plant is a glabrous perennial under-shrub with erect or sub-scandent nodose stem and slender branches, the latter are often creeping or trailing and rooting below or rarely scandent reaching a few metres height. Leaves are simple, alternate, stipulate, and petiolate or nearly sessile; lower ones broadly ovate, cordate; upper ones oblong, oval, all entire, smooth, thin with reticulate venation; veins raised beneath. It flowers nearly throughout the year. Inflorescence is spike with unisexual small achlamydeous densely packed flowers and form very close clusters of small greyish green or darker grey berries. Female spikes with short thick stalk varying from 1.5 to2.5 cm in length and 0.5 to 0.7 cm in thickness.

A number of geographical races are available in different agroclimatic regions of India; the most popular being Assam, West Bengal and Nepal races. Piper officinarum DC; syn. Chavica officinarum Miquel, Piper pepuloides and Piper chaba Hunter are the other related species of importance.

Agrotechnology: Long pepper is a tropical plant adapted to high rainfall areas with high humidity. An elevation of 100-1000 m is ideal. It needs partial shade to the tune of 20-30% for best growth. The natural habitat of the plant is on the borders of streams. It is successfully cultivated in well drained forest soils rich in organic matter. Laterite soils with high organic matter content and moisture holding capacity are also suitable for cultivation.

Long pepper is propagated by suckers or rooted vine cuttings.15-20 cm long 3-5 nodded rooted vine cuttings establishes very well in polybags. The best time for raising nursery is March-April. Normal irrigation is given on alternate days. The rooted cuttings will be ready for transplanting in 2 months time. With the onset of monsoon in June the field is ploughed well and brought to good tilth. 15-20 cm raised beds of convenient length and breadth are taken. On these beds, pits are dug at 60 x 60 cm spacing and well decomposed organic manure at 100 g/pit is applied and mixed with the soil. Rooted vine cuttings from polybags are transplanted to these pits. Gap filling can be done after one month of planting.The crop needs heavy manuring at the rate of 20 t FYM/ha every year. Application of heavy dose organic matter and mulching increase water retention in the soil and control weeds. Small doses of chemical fertilisers can also be used. The crop needs irrigation once a week. Sprinkler irrigation is ideal. With irrigation the crop continues to produce spikes and off-season produce will be available. However, it is reported that unirrigated crop after the onset of monsoon grows vigorously and shows much hardiness than the irrigated crop.

Crop losses can be heavy due to pests and diseases. Mealy bugs and root grubs, attack the plant particularly during summer. Infested plants show yellowing and stunted growth. Application of systemic insecticides like nuvacron or dimecron will control the pests. Adults and nymphs of Helopeltis theivora severely feeds on the foliage which can be controlled by 0.25% neem kernel suspension. Rotting of leaves and vines during monsoon season is caused by Colletotrichum glorosporiodes and necrotic lesions and blights on the leaves during summer is caused by Colletotrichum and Cercospora spp. These diseases can be controlled by spraying of 1% Bordeaux mixture repeatedly. A virus like disease characterised by yellowing and crinkling of leaves, stunted growth and production of spikes of smaller size and inferior quality was also recently reported.

The vines start flowering six months after planting and flowers are produced almost throughout the year. The spikes mature in 2 months time. The optimum stage of harvest is when the spikes are blackish green. The pungency is highest at this stage. Spikes are hand picked when they become mature and then dried. The yield of dry spike is 400 kg /ha during first year, increases to 1000kg during third year and thereafter it decreases. Therefore, after 3 years the whole plant is harvested. The stem is cut close to the ground and roots are dug up. Average yield is 500 kg dry roots/ha (Viswanathan,1995).

Piper longum can also be cultivated as an intercrop in plantations of coconut, subabul and eucalyptus.

Post harvest technology: The harvested spikes are dried in sun for 4-5 days until they are perfectly dry. The green to dry spike ratio is 10:1.5 by weight. The dried spikes have to be stored in moisture proof containers. Stem and roots are cleaned, cut into pieces of 2.5-5 cm length, dried in shade and marketed as piplamool. There are three grades of piplamool, based on the thickness. The commercial drug consists 0.5-2.5 cm long ,0.5-2.5 mm thick, cylindrical pieces dirty light brown in colour and peculiar odour with a pungent bitter taste, producing numbness to the tongue.

Properties and activity: The spike of long pepper contains 4-5% piperine, piplartin, piperolactam, N-isobutyl deca trans-2-trans-4-dienamide and piporadione alkaloides, besides 0.7 % essential oil. Roots gave the alkaloids piperine, piperlongumine (piplartine) and piperlonguminine; sesamine, methyl 3, 4, 5-trimethoxy cinnamate. Stem gave triacoutane 22, 23 - dihydrostigmasterol. Fruit essential oil contains piperidine, caryophyllene and sesquiterpene alcohol (Atal et al, 1975).

The root is plungent, hot, stomachic, laxative, anthelmintic and carminative. The fruit is sweetish, pungent, hot, stomachic, aphrodisiac, alterative, laxative, antidysenteric, emmenagogue, abortifacient, diuretic and tonic. The essential oil is antimicrobial and anthelmintic.

N-isobutyl-deca-trans-2-trans-4-dienamide is antitubercular.

Piperine is hypotensive, antipyretic, analeptic, and nerve stimulant (Warrier et al, 1995).... long pepper

Rutaceae

San: Bilva, Sriphal Hin, Ben, Ass: Bael Mal: Koovalam

Tam: Vilvam Mar,

Ben: Baela

Tel: Marendu, Bilvapondu

Guj: Bilviphal

Kan: Bilvapatra

Importance: Bael or Bengal quince is a deciduous sacred tree, associated with Gods having useful medicinal properties, especially as a cooling agent. This tree is popular in ‘Shiva’ and ‘Vishnu’ temples and it can be grown in every house. Its leaves are trifoliate symbolizing the ‘Thrimurthies’-Brahma, Vishnu, Shiva, with spear shaped leaflets resembling “Thrisoolam” the weapon of Lord Shiva. Many legends, stories and myths are associated with this tree. The leaflets are given to devotees as ‘prasadam’ in Shiva temples and as ‘Tulasi’ in Vishnu temples.

Every part of the tree is medicinal and useful. The roots are used in many Ayurvedic medicines for curing diabetes and leprosy. It is an ingredient of the ‘dasamoola’. The Bark is used to cure intestinal disorders. Leaves contain an alkaloid rutacin which is hypoglycaemic.

‘Two leaves before breakfast’ is said to keep diabetes under control. Leaves and fruits are useful in controlling diarrhoea and dysentery. Fruit pulp is used as ‘shampoo’ and cooling agent. It is also a rich source of carbohydrate, protein, fat, fibre, minerals and vitamin B and C. Fruit pulp is used to cure mouth ulcers as it is the richest natural source of riboflavin (1191 units/ 100 g). ‘Bael sharbat’ is prepared by mixing the fruit pulp with sugar, water and tamarind juice, which is very useful for stomach and intestinal disorders. The rind of the fruit is used for dyeing and tanning. The aromatic wood is used to make pestles in oil and sugar mills and also to make agricultural implements (Rajarajan, 1997).

Distribution: Bael tree is native to India and is found growing wild in Sub-Himalayan tracts from Jhelum eastwards to West Bengal, in central and south India. It is grown all over the country, especially in the premises of temples and houses.

Botany: Aegle marmelos (Linn.) Corr.ex Roxb. belongs to the citrus family Rutaceae. The golden coloured bael fruit resembles a golden apple and hence the generic name Aegle. The specific name marmelos is derived from marmelosin contained in the fruit (Nair, 1997). Aegle marmelos is a medium sized armed deciduous tree growing upto 8m in height with straight sharp axillary thorns and yellowish brown shallowly furrowed corky bark. Leaves are alternate, trifoliate and aromatic; leaflets ovate or ovate-lanceolate, crenate, pellucid- punctate, the laterals subsessile and the terminal long petioled. Flowers are greenish-white, sweet scented, borne on axillary panicles. Fruit is globose, woody berry with golden yellow rind when ripe. Seeds are numerous oblong, compressed and embedded in the orange brown sweet gummy pulp.

Agrotechnology: Bael comes up well in humid tropical and subtropical climate. It grows on a wide range of soils from sandy loam to clay loam. North Indian varieties are preferred to South Indian types for large scale cultivation. Twelve varieties are cultivated in North India for their fruits. Kacha, Ettawa, Seven Large, Mirsapuri and Deo Reo Large are varieties meant specially for ‘Sharbat’. The plant is propagated mainly by seeds and rarely by root cuttings. Seeds are freshly extracted from ripe fruits after removing the pulp and then dried in sun. Seeds are soaked in water for 6 hours and sown on seed beds which are covered with rotten straw and irrigated regularly. Seeds germinate within 15-20 days. One month old seedlings can be transplanted into polybags which can be planted in the field after 2 months. Budded or grafted plants as well as new saplings arising from injured roots can also be used for planting. Grafted plants start yielding from the 4th year while the trees raised from seeds bear fruits after 7-10 years. Planting is done in the main field with onset of monsoon in June-July at a spacing of 6-8m. Pits of size 50cm3 are dug. Pits are filled with a mixture of top soil and 10kg of well decomposed FYM and formed into a heap. Seedlings are transplanted in the middle of the heap and mulched. Chemical fertilisers are not usually applied. The dose of organic manure is increased every year till 50kg/tree of 5 years or more. Regular irrigation and weeding are required during early stages of growth. No serious pests and diseases are noted in the crop. Bael tree flowers during April. The flowers are aromatic with pleasant and heavenly odour. The fruits are set and slowly develop into mature fruits. Fruits are seen from October-March. A single tree bears 200-400 fruits each weighing 1-2 kg. Roots can be collected from mature trees of age 10 years or more. Tree is cut down about 1m from the ground. The underground roots are carefully dug out. Roots with the attached wood is then marketed (Rajarajan,1997).

Properties and activity: Bael is reported to contain a number of coumarins, alkaloids, sterols and essential oils. Roots and fruits contain coumarins such as scoparone, scopoletin, umbelliferone, marmesin and skimmin. Fruits, in addition, contain xanthotoxol, imperatorin and alloimperatorin and alkaloids like aegeline and marmeline identified as N-2-hydroxy-2- 4 - (3’,3’-dimethyl allyloxy) phenyl ethyl cinnamide. - sitosterol and its glycoside are also present in the fruits. Roots and stem barks contain a coumarin - aegelinol. Roots also contain psoralen, xanthotoxin, 6,7-dimethoxy coumarin, tembamide, mermin and skimmianine. Leaves contain the alkaloids - O-(3,3-dimethyl allyl)-halfordinol, N-2-ethoxy-2 (4-methoxy phenyl) ethyl cinnamide, N-2-methoxy-2-(4-3’,3’-dimethyl allyloxy) phenyl ethyl cinnamide, N- 2-4-(3’,3’-dimethyl allyloxy) phenyl ethyl cinnamide, N-2-hydroxy-2- 4-(3’,3’-dimethyl allyloxy) phenyl ethyl cinnamide, N-4-methoxy steryl cinnamide and N-2-hydroxy-2-(4- hydroxy phenyl) ethyl cinnamide. Mermesinin, rutin and -sitosterol - -D-glucoside are also present in the leaves (Husain et al, 1992).

Root, bark, leaves and fruits are hypoglycaemic, astringent and febrifuge. Root, stem and bark are antidiarrhoeal and antivenin. Leaf is antiinflammatory, expectorant, anticatarrhal, antiasthamatic, antiulcerous and ophthalmic. Flower is emetic. Unripe fruit is stomachic and demulcent. Ripe fruit is antigonorrhoeal, cardiotonic, restorative, laxative, antitubercular, antidysenteric and antiscorbutic. Seed is anthelmintic and antimicrobial (Warrier et al, 1993).... bael

Dioscorea spp.

Dioscoreaceae

The growing need for steroidal drugs and the high cost of obtaining them from animal sources led to a widespread search for plant sources of steroidal sapogenins, which ultimately led to the most promising one. It is the largest genus of the family constituted by 600 species of predominantly twining herbs. Among the twining species, some species twine clockwise while others anti-clockwise (Miege, 1958). All the species are dioceous and rhizomatous. According to Coursey (1967), this genus is named in honour of the Greek physician Pedenios Dioscorides, the author of the classical Materia Medica Libri Quinque. Some of the species like D. alata and D. esculenta have been under cultivation for a long time for their edible tubers. There are about 15 species of this genus containing diosgenin. Some of them are the following (Chopra et al, 1980).

Among the above said species, D. floribunda, D. composita and D. deltoidea are widely grown for diosgenin production.

1. D. floribunda Mart. & Gal D. floribunda Mart. & Gal. is an introduction from central America and had wide adaptation as it is successfully grown in Karnataka, Assam, Meghalaya, Andaman and Goa. The vines are glabrous and left twining. The alternate leaves are borne on slender stems and have broadly ovate or triangular ovate, shallowly cordate, coriaceous lamina with 9 nerves. The petioles are 5-7cm long, thick and firm. Variegation in leaves occurs in varying degrees. The male flowers are solitary and rarely in pairs. Female flowers have divericate stigma which is bifid at apex. The capsule is obovate and seed is winged all round. The tubers are thick with yellow coloured flesh, branched and growing upto a depth of 30cm (Chadha et al, 1995).

2. D. composita Hemsl.

D. composita Hemsl. according to Knuth (1965) has the valid botanical name as D. macrostachya Benth. However, D. composita is widely used in published literature. It is a Central American introduction into Goa, Jammu, Bangalore, Anaimalai Hills of Tami Nadu and Darjeeling in W. Bengal. The vines are right twinning and nearly glabrous. The alternate leaves have long petioles, membraneous or coriaceous lamina measuring upto 20x18cm, abruptly acute or cuspidate-acuminate, shallowly or deeply cordate, 7-9 nerved. The fasciculate-glomerate inflorescence is single or branched with 2 or 3 sessile male flowers having fertile stamens. Male fascicle is 15-30cm long. The female flowers have bifid stigma. Tubers are large, white and deep-rooted (upto 45cm) (Chadha et al, 1995).

3. D. deltoidea Wall. ex. Griseb.

D. deltoidea Wall. ex. Griseb. is distributed throughout the Himalayas at altitudes of 1000-3000m extending over the states of Jammu-Kashmir, H. P, U. P, Sikkim and further into parts of W. Bengal. The glabrous and left twining stem bears alternate petiolate leaves. The petioles are 5-12 cm long. The lamina is 5-15cm long and 4-12cm wide widely cordate. The flowers are borne on axillary spikes, male spikes 8-40cm long and stamens 6. Female spikes are 15cm long, 3. 5cm broad and 4-6 seeded. Seeds are winged all round. Rhizomes are lodged in soil, superficial, horizontal, tuberous, digitate and chestnut brown in colour (Chadha et al, 1995). D. deltoidea tuber grows parallel to ground covered by small scale leaves and is described as rhizome. The tubers are morphologically cauline in structure with a ring of vascular bundles in young tubers which appear scattered in mature tubers (Purnima and Srivastava, 1988). Visible buds are present unlike in D. floribunda and D. composita where the buds are confined to the crown position (Selvaraj et al, 1972).

Importance of Diosgenin: Diosgenin is the most important sapogenin used as a starting material for synthesis of a number of steroidal drugs. For commercial purposes, its -isomer, yamogenin is also taken as diosgenin while analysing the sample for processing. Various steroidal drugs derived from diosgenin by artificial synthesis include corticosteroids, sex hormones, anabolic steroids and oral contraceptives. Corticosteroids are the most important group of steroidal drugs synthesized from diosgenin. First group of corticosteroids regulates carbohydrate and protein metabolism. The second group consists of aldosterone, which controls balance of potassium, sodium and water in the human body. The glucocorticoids in the form of cortisone and hydrocortisone are used orally, intramuscularly or topically for treatment of rheumatoid arthritis, rheumatic fever, other collegen diseases, ulcerative colitis, certain cases of asthma and a number of allergic diseases affecting skin, eye and the ear. These are also used for treatment of gout and a variety of inflammations of skin, eye and ear and as replacement therapy in Addison’s diseases. The minerato corticoides, desoxycorticosterone or desoxycortone are used in restoring kidney functions in cases of cortical deficiency and Addison’s disease.

Both male and female sex hormones are also synthesized from disosgenin. The main male sex hormone (androgen) which is produced from disogenin is testosterone. The main female sex hormones produced are oestrogen and progesterone. Recently oestrogen has also been used in cosmetic lotions and creams to improve the tone and colour of skin. One of the main uses of progesterone during recent years has been as antifertility agent for oral contraceptives. These artificial steroids have increased oral activity and fewer side effects, as they can be used in reduced doses. Oral contraceptives are also used for animals like pigs, cows and sheep to control fertility and to give birth at a prescribed period in a group of animals at the same time. These compounds are also used to reduce the interval between the lactation periods to have more milk and meat production. Anti-fertility compounds are also used as a pest-control measure for decreasing the multiplication of pests like rodents, pigeons and sea gulls (Husain et al, 1979).

Although yam tubers contain a variety of chemical substances including carbohydrates, proteins, alkaloids and tannins, the most important constituents of these yams are a group of saponins which yield sapogenins on hydrolysis. The most imp ortant sapogenin found in Dioscorea are diosgenin, yamogenin and pannogenin. Diosgenin is a steroid drug precursor. The diogenin content varies from 2-7% depending on the age of the tubers. Saponins including 5 spirastanol glucoside and 2 furostanol glucoside, 4 new steroid saponins, floribunda saponins C, D, E and F. Strain of A and B are obtained from D. floribunda (Husain et al, 1979). Rhizomes of D. deltoidea are a rich source of diosgenin and its glycoside. Epismilagenin and smilagenone have been isolated from D. deltoidea and D. prazeri (Chakravarti et al, 1960; 1962). An alkaloid dioscorine has been known to occur in D. hispida (Bhide et al,1978). Saponin of D. prazeri produced a fall of blood pressure when given intravenously and saponin of D. deltoidea has no effect on blood pressure (Chakravarti et al,1963). Deltonin, a steroidal glycoside, isolated from rhizomes of D. deltoidea showed contraceptive activity (Biokova et al, 1990).

Agrotechnology: Dioscorea species prefer a tropical climate without extremity in temperature. It is adapted to moderate to heavy rainfall area. Dioscorea plants can be grown in a variety of soils, but light soil is good, as harvesting of tubers is easier in such soils. The ideal soil pH is 5.5-6.5 but tolerates fairly wide variation in soil pH. Dioscorea can be propagated by tuber pieces, single node stem cuttings or seed. Commercial planting is normally established by tuber pieces only. Propagation through seed progeny is variable and it may take longer time to obtain tuber yields. IIHR, Bangalore has released two improved varieties, FB(c) -1, a vigorously growing strain relatively free from diseases and Arka Upkar, a high yielding clone. Three types of tuber pieces can be distinguished for propagation purpose, viz. (1) crown (2) median and (3) tip, of which crowns produce new shoots within 30 days and are therefore preferred. Dipping of tuber pieces for 5 minutes in 0.3% solution of Benlate followed by dusting the cut ends with 0.3% Benlate in talcum powder in mo ist sand beds effectively checks the tuber rot. The treatment is very essential for obtaining uniform stand of the crop. The best time of planting is the end of April so that new sprouts will grow vigorously during the rainy season commencing in June in India. Land is to be prepared thoroughly until a fine tilth is obtained. Deep furrows are made at 60cm distance with the help of a plough. The stored tuber pieces which are ready for planting is to be planted in furrows with 30cm between the plants for one year crop and 45cm between the plants for 2 year crop at about 0.5 cm below soil level. The new sprouts are to be staked immediately. After sprouting is complete, the plants are to be earthed up. Soil from the ridges may be used for earthing up so that the original furrows will become ridges and vice versa. Dioscorea requires high organic matter for good tuber formation. Besides a basal doze of 18-20t of FYM/ha, a complete fertilizer dose of 300kg N, 150kg P2O5 and K2O each are to be applied per hectare. P and K are to be applied in two equal doses one after the establishment of the crop during May-June and the other during vigorous growth period of the crop (August- September). Irrigation may be given at weekly intervals in the initial stage and afterwards at about 10 days interval. Dioscorea vines need support for their optimum growth and hence the vines are to be trailed over pandal system or trellis. Periodic hand weeding is essential for the first few months. Intercropping with legumes has been found to smother weeds and provide extra income. The major pests of Dioscorea are the aphids and red spider mites. Aphids occur more commonly on young seedlings and vines. Young leaves and vine tips eventually die if aphids are not controlled. Red spider mites attack the underside of the leaves at the base near the petiole. Severe infestations result in necrotic areas, which are often attacked by fungi. Both aphids and spider mites can be very easily controlled by Kelthane. No serious disease is reported to infect this crop. The tubers grow to about 25-30 cm depth and hence harvesting is to be done by manual labour. The best season for harvesting is Feb-March, coinciding with the dry period. On an average 50-60t/ha of fresh tubers can be obtained in 2 years duration. Diosgenin content tends to increase with age, 2.5% in first year and 3-3.5% in the second year. Hence, 2 year crop is economical (Kumar et al, 1997).... medicinal yams

About Psyllium Tea Psyllium tea is made from the seeds of the psyllium plant. The plant, also known as Isphangula, grows in many European countries, as well as in India. Psyllium is an herbal plant with a short stem. Its leaves are arranged alternatively, while the flowers are white, erect and ovoid; they can also have cylindrical spikes, giving them a stranger shape. The plant has an ovate fruit, with a thin husk, either white-colored or semi-transparent; the seeds, used to make psylliumtea, are found inside it. How to prepare Psyllium Tea The seeds are mostly used to prepare psyllium tea, but the husks can be used, as well. Add 1-2 teaspoons to a cup of freshly boiled water, cover and let it steep for 5-7 minutes. Strain to remove the herbs and your cup of tea is ready! You can also drink it cold. You can either let the psyllium tea cool down, or you can add the seeds and husks to a glass of cold water. Psyllium Tea Benefits Psyllium tea gets many active constituents from the seeds and husks of the plant. The most important one is fiber. It also contains a large amount of hemicellulose. Psyllium tea works as a great natural laxative. Because of this, it can be used in the treatment for irritable bowel syndrome, inflammatory bowel syndrome, and other similar health problems. They also help your digestive system by preventing disorders such as chronic constipation, mild diarrhea, or hemorrhoids. Drinking this tea will help reduce the bad LDL cholesterol levels in your blood, which helps you lose weight.

Agrotechnology: The agrotechnology for the solanaceous group of plants are almost similar. They come up very well in tropical and subtropical climate upto 2000m altitude. They can be raised on a variety of soils good in organic matter. Propagation is by seeds. The seedlings are first raised in the nursery and transplanted to the main field 30-45 days after sowing when the plants attain 8-10cm height. During rainy season, planting is done on ridges while during summer in furrows, at a spacing ranging from 30-90cm depending upon the stature and spreading habit of the plant. The transplanted seedlings should be given temporary shade for 2-4 days during summer. FYM or compost at 20-25t/ha is applied at the time of land preparation. A moderate fertiliser dose of 75:40:40 N, P2O5, K2O/ha may be given. P is given as basal dose, N and K are applied in 2-3 split doses. One or two intercultural operations are needed to control weeds. The plants need earthing up after weeding and topdressing. Irrigation is needed at 3-4 days interval during summer and on alternate days during fruiting period. Plants need staking to avoid lodging due to heavy bearing. Shoot borers, mealy bugs, leaf webbers and miners are noted on the crop, which can be controlled by spraying mild insecticides. Root knot nematode, wilting and mosaic diseases are also noted on the crop. Field sanitation, crop rotation and burning of crop residues are recommended.... solanums

Cinchona spp.

Rubiaceae

San: Cinchona, Kunayanah

Hin: Kunain Mal: Cinchona, Quoina

Tam: Cinchona

Importance: Cinchona, known as Quinine, Peruvian or Crown bark tree is famous for the antimalarial drug ‘quinine’ obtained from the bark of the plant. The term cinchona is believed to be derived from the countess of cinchon who was cured of malaria by treating with the bark of the plant in 1638. Cinchona bark has been valued as a febrifuge by the Indians of south and central America for a long time. Over 35 alkaloids have been isolated from the plant; the most important among them being quinine, quinidine, cinchonine and cinchonidine. These alkaloids exist mainly as salts of quinic, quinovic and cinchotannic acids. The cultivated bark contains 7-10% total alkaloids of which about 70% is quinine. Similarly 60% of the total alkaloids of root bark is quinine. Quinine is isolated from the total alkaloids of the bark as quinine sulphate. Commercial preparations contain cinchonidine and dihydroquinine. They are useful for the treatment of malarial fever, pneumonia, influenza, cold, whooping couphs, septicaemia, typhoid, amoebic dysentery, pin worms, lumbago, sciatica, intercostal neuralgia, bronchial neuritis and internal hemorrhoids. They are also used as anesthetic and contraceptive. Besides, they are used in insecticide compositions for the preservation of fur, feathers, wool, felts and textiles. Over doses of these alkaloids may lead to deafness, blindness, weakness, paralysis and finally collapse, either comatose or deleterious. Quinidine sulphate is cardiac depressant and is used for curing arterial fibrillation.

Distribution: Cinchona is native to tropical South America. It is grown in Bolivia, Peru, Costa Rica, Ecuador, Columbia, Indonesia, Tanzania, Kenya, Zaire and Sri Lanka. It was introduced in 1808 in Guatemala,1860 in India, 1918 in Uganda, 1927 in Philippines and in 1942 in Costa Rica. Roy Markham introduced the plant to India. The first plantation was raised in Nilgiris and later on in Darjeeling of West Bengal. The value of the tree was learnt by Jessuit priests who introduced the bark to Europe. It first appeared in London pharmacopoeia in 1677 (Husain, 1993).

Botany: The quinine plant belongs to the family Rubiaceae and genus Cinchona which comprises over 40 species. Among these a dozen are medicinally important. The commonly cultivated species are C. calisaya Wedd., C. ledgeriana Moens, C. officinalis Linn., C. succirubra Pav. ex Kl., C. lancifolia and C. pubescens. Cinchona species have the chromosome number 2n=68. C. officinalis Linn. is most common in India. It is an evergreen tree reaching a height of 10-15m. Leaves are opposite, elliptical, ovate- lanceolate, entire and glabrous. Flowers are reddish-brown in short cymbiform, compound cymes, terminal and axillary; calyx tubular, 5-toothed, obconical, subtomentose, sub-campanulate, acute, triangular, dentate, hairy; corolla tube 5 lobed, densely silky with white depressed hairs, slightly pentagonal; stamens 5; style round, stigma submersed. Fruit is capsule ovoid-oblong; seeds elliptic, winged margin octraceous, crinulate-dentate (Biswas and Chopra, 1982).

Agrotechnology: The plant widely grows in tropical regions having an average minimum temperature of 14 C. Mountain slopes in the humid tropical areas with well distributed annual rainfall of 1500-1950mm are ideal for its cultivation. Well drained virgin and fertile forest soils with pH 4.5-6.5 are best suited for its growth. It does not tolerate waterlogging. Cinchona is propagated through seeds and vegetative means. Most of the commercial plantations are raised by seeds. Vegetative techniques such as grafting, budding and softwood cuttings are employed in countries like India, Sri Lanka, Java and Guatemala. Cinchona succirubra is commonly used as root stock in the case of grafting and budding. Hormonal treatment induces better rooting. Seedlings are first raised in nursery under shade. Raised seedbeds of convenient size are prepared, well decomposed compost or manure is applied , seeds are broadcasted uniformly at 2g/m2, covered with a thin layer of sand and irrigated. Seeds germinate in 10-20 days. Seedlings are transplanted into polythene bags after 3 months. These can be transplanted into the field after 1 year at 1-2m spacing. Trees are thinned after third year for extracting bark , leaving 50% of the trees at the end of the fifth year. The crop is damaged by a number of fungal diseases like damping of caused by Rhizoctoria solani, tip blight by Phytophthora parasatica, collar rot by Sclerotiun rolfsii, root rot by Phytophthora cinnamomi, Armillaria mellea and Pythium vexans. Field sanitation, seed treatment with organo mercurial fungicide, burning of infected plant parts and spraying 1% Bordeaux mixture are recommended for the control of the diseases (Crandall, 1954). Harvesting can be done in one or two phases. In one case, the complete tree is uprooted, after 8-10 years when the alkaloid yield is maximum. In another case, the tree is cut about 30cm from the ground for bark after 6-7 years so that fresh sprouts come up from the stem to yield a second crop which is harvested with the under ground roots after 6-7 years. Both the stem and root are cut into convenient pieces, bark is separated, dried in shade, graded, packed and traded. Bark yield is 9000-16000kg/ha (Husain, 1993).

Properties and activity: Over 35 alkaloids have been isolated from Cinchona bark, the most important among them are quinine, quinidine, cinchonine, cinchonidine, cinchophyllamine and idocinchophyllamine. There is considerable variation in alkaloid content ranging from 4% to 20%. However, 6-8% yield is obtained from commercial plantations. The non alkaloidal constituents present in the bark are bitter glycosides, -quinovin, cinchofulvic, cinchotannic and quinic acids, a bitter essential oil possessing the odour of the bark and a red coloring matter. The seed contains 6.13% fixed oil. Quinine and its derivatives are bitter, astringent, acrid, thermogenic, febrifuge, oxytocic, anodyne, anti-bacterial, anthelmintic, digestive, depurative, constipating, anti pyretic, cardiotonic, antiinflammatory, expectorant and calcifacient (Warrier et al, 1994; Bhakuni and Jain, 1995).... cinchona

The whole plant is useful in hyperdipsia, vitiated conditions of pitta, burning sensation, strangury, leprosy, skin diseases, leucoderma, fever, vomiting, diarrhoea, ulcers and as hair tonic.

3. Coleus forskohlii Briq. syn. C. barbatus Benth.

Hin: Garmai

Kan: Maganiberu, Makandiberu

Guj: Maimul

It is a perennial aromatic herb grown under tropical to temperate conditions for its carrot-like tubers which are used as condiments in the preparation of pickles. Its tuberous roots are an exclusive source of a diterpenoid forskolin which has the unique property of activating almost all hormone sensitive adenylate cyclase enzymes in a biological system. It is useful in the treatment of congestive heart failure, glaucoma, asthma, cancer and in preventing immature greying of hair (Hegde,1997).

Agrotechnology: The Coleus group of plants grows in tropical to subtropical situations and in warm temperate climatic zone on mountains of India, Nepal, Burma, Sri Lanka, Thailand and Africa. It comes up well on the sun exposed dry hill slopes from 300m to 1800m altitude. A well drained medium fertile soil is suitable for its cultivation. it is propagated vegetatively through stem and root cuttings. Vine cuttings to a length of 10-15cm from the top portion are most ideal for planting. The land is ploughed or dug to a depth of 15-20cm and ridges are formed 30cm apart. Vine cuttings are planted on the ridges at 30cm spacing after incorporating basal manure. 10t of FYM and NPK at 50:50:50kg/ha are incorporated into the soil. Top dressing of N and K is also suggested for improved yields. Weeding and earthing up at 45 days after planting along with topdressing is highly beneficial. Bacterial wilt and root knot nematode are reported in the crop. Drenching the soil with fungicide, deep ploughing in the summer, burning of crop residues and crop rotation are helpful to tide over the disease and pest problem. The crop can be harvested after 5-6 months.

Properties and activity: The medicinal property of Coleus amboinicus is attributed to codeine, carvacrol, flavones, aromatic acids and tannins present in the plant. The essential oil from the plant contains carvacrol, ethyl salicylate, thymol, eugenol and chavicol. Leaves also contain cirsimaritin, -sitosterol- -D-glucoside and oxalacetic acid. Leaves are bitter, acrid, thermogenic, aromatic, anodyne, appetising, digestive, carminative, stomachic, anthelmintic, constipating, deodorant, expectorant, diuretic and liver tonic.

Coleus vettiveroides is bitter, cooling, diuretic, trichogenous and antipyretic.

Coleus forskohlii roots are rich in diterpenoids like forskolin, coleonols, coleons, barbatusin, cyclobutatusin, coleosol, coleol, coleonone, deoxycoleonol, 7-deacetylforskolin and 6-acetyl-7-deacetylforskolin. Its root is spasmolytic, CNS active, hypothermic and diuretic. Forskolin is bronchodialative and hypotensive (Hussain et al,1992). Forskolin is also useful in preventing the clotting of blood platelets, in reducing intraocular pressure in glaucoma and as an aid to nerve regeneration following trauma (Sharma, 1998)... coleus

Importance: Curry leaf, a plant of homestead gardens has gained importance as a commercial crop and is cultivated for its culinary and medicinal value. The plant is highly esteemed for its leaves which promote appetite and digestion and destroy pathogenic organisms. It is reported to be useful in emaciation, skin diseases, hemopathy, worm troubles, neurosis and poisons. They are useful in vitiated conditions of kapha and pitta, hyperdipna, colic, flatulence, diarrhoea, dysentery, vomiting, inflammations and foul ulcers. “Kaidaryah” drug is prepared using this plant which improves voice, stimulates digestion and destroys concocted poisons in the system. The important preparations using the drug are Kalasadi kasayam, Pamantaka tailam, Jatyadi tailam, Jatyadi ghrtam, etc (Sivarajan et al,1994).

Distribution: Curry leaf is seen in the foot of the Himalaya and Bashahi eastwards to Sikkim and Peninsular India, upto 1700m. It is also found in Sri Lanka, Burma, Indo-China, South China and Hainan. Commercial cultivation in India is limited to Tamil Nadu and Karnataka states.

Botany: The genus Murraya of the family Rutaceae includes the following species:

M. Koenigii (Linn.) Spreng. syn. Bergera koenigii Linn.

M. Exotica Linn. syn. M. paniculata (Linn.) Jack.

Murraya koenigii is a small aromatic tree with dark grey bark and closely crowded spreading dark green foliage. Leaves are imparipinnate and alternate. Leaflets are alternate, obliquely ovate or somewhat rhomboid, gland dotted and strongly aromatic. Flowers are white, arranged in much branched terminal corymbose cymes and fragrant. Fruits are subglobose or ellipsoid berries, purplish black when ripe and 2-seeded (Warrier et al, 1995).

Agrotechnology: Curry leaf tree does not choose a specific climate and can come up even in dry climate too. In places where minimum temperature goes below 13 C, the growth of the shoot will be slightly affected. It comes up well in light textured red soils. DWD-1 and DWD-2 are two improved varieties released from UAS, Dharwad. Curry leaf is propagated by seed. Main field is to be ploughed repeatedly. A spacing of 90-120cm is followed on either side. Pits of size 30cm3 are dug out one month before planting and filled with top soil mixed with well decomposed FYM at the time of planting. Healthy seedlings are planted in the centre of the pits. Then long furrows are formed connecting all the pits to facilitate easy irrigation. The seedlings are irrigated once in 5-7 days upto 3 years and once in 15 days afterwards. The field should be kept free from weeds. Plants may be trained and pruned to maintain a bush of 1m in height. For better growth and yield, each plant is fertilised with 20kg of FYM besides 150:25:50g of N, P2O5, K2O/ year. Attack of aphids in the vegetative stage can be controlled by spraying of dimethoate at 2ml/l of water. Leaves from such sprayed plants should be harvested only after 10 days. Spraying carbendazim at 1g/l can take care of leaf spot diseases. The crop comes to first harvest at the end of first year. The yield of leaves account to 400kg/ha at the end of first year, 2000 to 2200kg/ha in the second and third year harvested at an interval of four months and 2500kg/ha in the fourth year harvested at three months interval. From fifth year onwards it is harvested at 2.5-3 months interval giving an yield of 3500-5000kg/ha (Kumar et al, 1997).

Properties and activity: All parts of the plant, especially the leaves are rich in carbazole alkaloids. These include members with (i) C13 - skeleton -murrayanin, mukoeic acid, mukonine and mukonidine; (ii) C18 - skeleton including gerinimbine, koenimbine, murrayacine, koenigine and koenigicine (koenidine); and (iii) C23- skeleton containing mahanimbine, mahanimbicine, iso- mahanimbicine, mahanine, mahanimbinine, murrayayazoline, murrayazolinine, murrayazolidine, cyclomahanimbine and bicyclomahanimbicine. Other carbazole bases include mukoline, mukolidine (C13 group, from roots), mukonicine (C18 from leaves), the biogenetically significant mukonal (C13, stem-bark), mahanimboline (C23, root-bark), iso- murrayazoline (C23, stem-bark). The leaves gave a coumarin glucoside, scopolin also. Essential oil from leaves contained -caryophylline, -gurjunene, -elemene, - phellandrene, -thujene as major constituents.

The roots, bark and leaves are bitter, acrid, astringent, cooling, aromatic, demulcent, depurative, anthelmintic, febrifuge, stomachic, appetising, carminative, antiinflammatory and antiseptic. Aerial part is spasmolytic and antiprotozoal. Root is antiprotozoal, CVS active and has effect on nictitating membrane. Leaf is hypoglycaemic (Hussain et al,1992).... curry leaf

Importance: Desmodium is a small shrub which is the chief of the ten ingredients in the Dasamula kwatha of Hindu medicine. Roots are useful in vitiated conditions of vata, anorexia, dyspepsia, haemorrhoids, dysentery, strangury, fever, gout, inflammations, cough, asthma, bronchitis, cardiopathy and debility. The unani preparation “Arq dashmul” contains these roots. It is considered a curative for leucorrhoea and for pains due to cold (Warrier et al, 1995).

Distribution: The plant is widely distributed in the tropics and subtropics. It grows wild in the forests of India up to 1500m. It is also cultivated in the plains and in the lower Himalayas.

Botany: Desmodium gangeticum (Linn.) DC. syn. Hedysarum gangeticum Linn., Desmodium gangeticum var. maculatum (Linn.) Baker., belongs to the family Fabaceae (Papilionaceae). It is an erect diffusely branched undershrub, 90-120cm in height with a short woody stem and numerous prostrate branches provided with soft grey hairs. Leaves are unifoliate, ovate- lanceolate, membranceous and mottled with grey patches. Flowers are white, purple or lilac in elongate lax, terminal or axillary racemes. Fruits are moniliform, 6-8 jointed, glabrescent pods, joints of pods separately pubescent with hooked hairs, joint separating when ripe into indehiscent one seeded segments. Seeds are compressed and reniform.

Agrotechnology: Desmodium can grow in a variety of climate and soils. However, it prefers tropical and subtropical climatic conditions. Although it can grow on all types of soils, waterlogged and highly alkaline soils are not suitable. Light sandy loam is preferred for commercial cultivation.

It is propagated through seeds. Seeds can be planted directly in the field or seedlings raised on the nursery beds and transplanted. Transplanting always gives better results in commercial cultivation, as it gives assured crop stand. Planting is done at a spacing of 40x20cm on flat beds or ridges. Organic manures are applied at the time of land preparation and thoroughly mixed with the soil. A little quantity of phosphatic and nitrogenous fertilizers are also applied for better crop growth. The inter-row spaces between plants, both in the field and nursery should be kept free from weeds by frequent weeding and hoeing as the plant suffers from weed competition, especially during early stages of growth. Manual hand weeding is usually done. Irrigation of seedlings just after planting is good for crop establishment. Although it can be cultivated as a rainfed crop under humid tropical conditions, irrigation every month is beneficial during summer. The root is the economic part and harvesting can be commenced after 8-9 months. About 500- 700kg roots can be harvested from a hectare of land per year.

Properties and activity: The root contains gangetin, gangetinin, desmodin, N,N-dimethyl tryptamine, hypaphorine, hordenine, candicine, N-methyl tyramine and -phenyl ethyl amine. The total alkaloid fraction showed hypotensive activity. The root is bitter, antiinflammatory, analgesic, aphrodisiac, constipating, diuretic, cardiotonic, expectorant, astringent, antidiarrhoeal, carminative, antiemetic, febrifuge and anti-catarrhal (Thakur et al, 1989).... desmodium

Gentiana lutea. N.O. Gentianaceae.

Habitat: Grows abundantly throughout France, Spain, and large areas of Central

Europe.

Part used ? Large quantities of Gentiana lutea root are imported into this country as it is preferred to the English variety (Gentiana campestris—see below) for no very apparent therapeutic reason. It is certain, however, that Gentian root, of whichever kind, is the most popular of all herbal tonics and stomachics—and deservedly so.

Features ? Gentiana lutea root is cylindrical in form, half to one inch thick, and ringed in the upper portion, the lower being longitudinally wrinkled. It is flexible and tough, internally spongy and nearly white when fresh, an orange-brown tint and strong distinctive odour developing during drying. The taste is extremely bitter.

A decoction of 1 ounce to 1 pint (reduced from 1 1/2 pints) of water, given in wineglass doses, will be found very helpful in dyspepsia and loss of tone, or general debility of the digestive organs. One of the effects of the medicine is to stimulate the nerve-endings of taste, thus increasing the flow of gastric juice. As a simple bitter it may be given in all cases when a tonic is needed.

The English Gentian (also known locally as Baldmoney and Felwort) grows to six inches high and is branched above. Leaves opposite, ovate- lanceolate above and ovate-spatulate below, entire margins. Flowers are bluish-purple. The whole herb may be used for the same purposes as the foreign root, although here also the root contains the more active principles.... gentian

Importance: Glory lily is a glabrous herbaceous climber which yields different types of troplone alkaloids of medicinal importance. The major alkaloids are colchicine , 3-demethyl colchicine and colchicoside. There is another alkaloid gloriosine which promises to be even more effective than colchicine in plant breeding for inducing polyploidy. The genus has importance in the ornamental horticulture due to its bright flowers and wiry climbing stem.

The roots and rhizomes are used in traditional system of medicine. Its abortifacient and antipyretic properties have been mentioned in ancient classics “Charaka”. The name Garbhaghatini is due to this abortifacient activity. They are useful in the treatment of inflammations, ulcers, scrofula, hemorrhoids, pruritus, dyspepsia, helminthiasis, flatulence, intermittent fevers and debility. The root is given internally as an effective antidote against cobra poison. A paste of the root is also used as an anodyne; applications in bites of poisonous insects, snake bites, scorpion sting, parasitic skin diseases and leprosy (Nadkarni,1954; Chaudhuri and Thakur; 1994).

Distribution: The plant is distributed throughout tropical India upto an altitude of 2500m and in Andaman islands. It is also cultivated in tropical and South Africa, Madagaskar, Indonesia and Malasia. It is reported to be cultivated in some parts of Europe. In India it was cultivated in RRL, Jammu in 1960s. Recently it was taken up by Indian Council of Agricultural Research(ICAR). Cultivation of the plant is mostly confined to the Southern states of India besides its collection from wild sources.

Botany: Gloriosa superba Linn. belongs to Liliaceae family. It is a glabrous climbing herb with tuberous root stock grows over hedges and small trees. Stem is 6m long which grows to a height of 1.2-1.5m before the stem branches. Leaves are simple, alternate or whorled, sessile, ovate-lanceolate, 17x4.5cm, tip elongating into a spirally coiled tendril, base cordate and margin entire. Flowers are large in terminal racemes; perianth segments 6, linear, flexuosus and deflexed, basal half bright yellow, upper half red; stamens 6; ovary glabrous, 3-celled. Fruits are capsules, linear-oblong, upto 6.8cm long, 3 equal lobes, one or two lobes shorter in malformed fruits; green dried to pale and then black colour, dehisced into three sections. Seeds are oval in shape, testa spongy, embryo cylindric, 30-150 seeds per capsule, pale orange attached to the sutures. Tubers are cylindric, large, simple, ‘V’ shaped with the two limps equal or unequal in lenth pointed towards end brownish externally and yellowish internally. (Narain, 1977)

Agrotechnology: This is a rainy season plant and sprouts well in warm, humid and tropical conditions. It should be grown in sun as the plants in shade become weedy and thin and move towards light. G. superba is a shallow rooted plant and grows well in a variety of soils either clay or sand through out India. It grows well in a light porous soil with good drainage. For vigorous growth, greater blooms and strong tuber, a mixture of soil, sand and compost manure is recommended. The propagation is mainly by tubers, by division of rhizomes. Seeds remain dormant for 6-9 months and due to hard seed coat, about 20-30 days are required for germination and seeds may take 3-4 years before it matures to flower. Treatment of seeds by gibberellin(1-3 ppm) resulted in higher yield of colchicine in the plant and higher production of tubers. In tissue culture, young sprouts are cultured on Murashige and Skoog’s medium (Msb) supplemented with kinetin (1-4 mg/l). Direct regeneration of the explants are obtained.

The seeds and rhizomes are sown usually in the last week of June to mid July. The rhizomes are planted by splitting carefully into two from their ‘V’ shaped joints (two buds being at the extreme end of each rhizome) in lines 20cm apart at a distance of 20cm (while seeds are sown in lines at a distance of 4-6cm apart). They are watered regularly when the plants are growing. After green shoots appear 2-3 showers are weekly. The irradiation of the plant at 42% natural sunlight intensity increased the production of tuber and colchicine. They usually takes 6-10 weeks to flower after sprouting and then set on fruits. The fruits ripen at the end of October and after that aerial shoot eventually dies, leaving the fleshy tubers underground. The tubers are dug out with great care. An individual plant produces 50g tubers on an average. The average yield is approximately 4000-5000kg of rhizomes and 1000 kg of seed per hectare. The content of colchicine is usually 0.358% and 1.013% in tubers and seeds, respectively.

Post harvest technology: Lixivation of the material is done with 70% ethyl alcohol. Concentrated under vacuum to one third of its volume and extracted with chloroform for colchicine and related substances-concentration of the aqueous phase to syrup which is extracted 6-8 times with a mixture of CHCl3 - alcohol (4:1) to yield colchicoside.

Properties and activity: The flowers, leaves and tubers contain colchicine, superbin, N-formyl deacetyl colchicine, demethyl colochicine and lumicolchicine. Tubers also contain gloriosine. Leaves in addition, contain chelidonic acid, 2-hydroxy 6-methoxy benzoic acid and -sitosterol glucoside. Colchicine, demethyl colchicine and colchicoside have been reported from seeds. Rhizome is oxytocic, anticancerous, antimalarial, stomachic, purgative, cholagogue, anthelmintic, alterative, febrifuge and antileprotic. Leaf is antiasthmatic and antiinflammatory. Root shows antigonorrhoeic and antibiotic activity. This plant has poisonous effect to enviroment and livestock. The toxic properties are due to presence of alkaloids chiefly colchicine (Clewer et al, 1915).... glory lily

Importance: Gymnema, Australian Cowplant, Small Indian Ipecacuanha or Periploca of the woods is a woody climber. It is reported to cure cough, dyspnoea, ulcers, pitta, kapha and pain in the eyes. The plant is useful in inflammations, hepatosplenomegaly, dyspepsia, constipation, jaundice, haemorrhoids, strangury, renal and vesical calculi, helminthiasis, cardiopathy, cough, asthma, bronchitis, intermittent fever, amenorrhoea, conjuctivitis and leucoderma. The fresh leaves when chewed have the remarkable property of paralysing the sense of taste for sweet and bitter substance for some time (Warrier et al, 1995). The drug is described as a destroyer of madhumeha (glycosuria) and other urinary disorders. Root has long been reputed as a remedy for snakebite. Leaves triturated and mixed with castor oil are applied to swollen glands and enlargement of internal viscera as the liver and spleen (Nadkarni, 1954). The drug is used to strengthen the function of heart, cure jaundice, piles, urinary calculi, difficult micturition and intermittent fevers (Sharma,1983). The drug enters into the composition of preparations like Ayaskrti, Varunadi kasaya, Varunadighrtam, Mahakalyanakaghrtam, etc. They suppress the activity of taste of tongue for sweet taste and for this reason it was considered that it destroys sugar, hence the name Madhunashini or Gurmar and has been prescribed as an anti-diabetic. The crude drug as well as its dried aqueous extract is mainly used in bronchial troubles.

Distribution: It is a tropical climber. It mainly grows in Western Ghats, Konkan, Tamil Nadu and some parts of Bihar. The plant is cultivated in plains of India but the drug is mainly important from Afghanistan and Iran.

Botany: Gymnema sylvestre (Retz.)R. Br. syn. Asclepias germinata Roxb. belonging to the family Asclepiadaceae is a large, woody much branched climber with pubescent young parts. Leaves are simple, opposite, elliptic or ovate, more or less pubescent on both sides, base rounded or cordate. Flowers are small, yellow and arranged in umbellate cymes. Fruits are slender and follicles are upto 7.5cm long (Warrier et al, 1995).

Two allied species, G. hirsutum found in Bundelkh and Bihar and Western Ghats and G. montanum growing wild in Eastern Ghats and Konkan are also used for the same purpose and are also called “Gurmar” (Thakur et al, 1989).

Agrotechnology: The plant can be propagated both by seeds and stem cuttings. Seedlings are to be raised in polybags. Pits of size 50cm cube are to be taken, filled with 10kg dried cowdung or FYM and covered with topsoil. On these pits about 3-4 months old seedlings are to be transplanted from polybags. Trailing can be facilitated by erecting poles and tying the plants to the poles. The plant will attain good spread within one year. Regular weeding, irrigation and organic manure application are beneficial. The plant is not attacked by any serious pests or diseases. Leaves can be collected from the first year onwards at an internal of one week. This can be continued for 10-12 years. Fresh or dried leaves can be marketed (Prasad et al, 1997).

Properties and activity: Nonacosane and hentriacontane were isolated from the hexane extract of leaves. An attempt to isolate nitrogenous compounds led to the isolation of amino acids such as leucine, iso-leucine, valine, allanine and - amynobutyric acid. Isolation of trimethyl amine oxide was of particular interest. An alkaloid gynamine which is a trace constituent was isolated and identified (Sinsheimer et al, 1967). Antisweet constituent of the leaves has been found to be a mixture of triterpene saponins. These have been designated as gymnemic acids A,B,C and D which have the gymnemagenin and gymnestrogenins as the aglycones of gymnemic acid A and B and gymnemic acid C and D respectively. These are hexahydroxy triterpenes the latter being partially acylated. The sugar residues are glucuronic acid and galacturonic acid while ferulic and angelic acids have been attached as the carboxylic acid.

Chewing of leaves reduces sensitivity to sweet substances. Effects of gymnema extracts had been variable. While verifying the effect of G. sylvestre leaves on detoxification of snake venom, it has been reported that a toxic component of venom ATP and gymnemate bind at the same site inhibiting venom ATP-ase. The active principles which have been identified as glycosides (7 gymnemic acids) suggest that the topical and selective anaesthetic effect of the plant might result from the competition of the receptor sites between glycosides and the sweet substances (Warren et al, 1969). The leaves are antidiabetic and insulinotropic. Gymnemic acid is antiviral. The plant is bitter, astringent, acrid, thermogenic, antiinflammatory, anodyne, digestive, liver tonic, emetic, diuretic, stomachic, stimulant, anthelmintic, alexipharmic, laxative, cardiotonic, expectorant, antipyretic and uterine tonic.... gymnema

Viola tricolor. N.O. Violaceae.

Synonym: Wild Pansy.

Habitat: Cultivated fields.

Features ? Stem short, square, smooth, branched. Leaves ovate-lanceolate, crenate. Flowers in June, petals of differing sizes, usually wholly yellow but occasionally purple upper petals with dark stripes on lower; single, violet-like flower to each flower stalk. Three carpel fruit.

Part used ? Herb.

Action: Diaphoretic, diuretic.

The mildness of action makes it applicable in infantile skin eruptions, for which the ounce to pint infusion is given in doses according to age.

It has been said that the medicine will ward off asthmatic and epileptic convulsions, but there would appear to be no reliable confirmation of this. The claim may have originated with Culpeper, who writes, concerning Heartsease ? "The spirit of it is excellently good for the convulsions in children, as also for falling sickness, and a gallant remedy for the inflammations of the lungs and breast, pleurisy, scabs, itch, etc."... heartsease

Ballota nigra. N.O. Labiateae.

Synonym: Crantz, Marrubium nigrum.

Habitat: Hedgerows, waste ground.

Features ? Stem stiff, erect, freely branched, up to four feet high. Leaves greyish-

green, upper ovate, lower cordate, in pairs, each pair pointing in opposite direction to next pair, crenate, hairy, stalked. Flowers (July and August) purplish, labiate, in rings just above leaves. Disagreeable odour.

Part used ? Herb.

Action: Stimulant, expectorant, diaphoretic, antispasmodic.

Coughs, colds and bronchial complaints generally. Hool prefers this herb to the white Horehound (Marrubium vulgare), and makes wide claims on its behalf. He recommends it in the treatment of consumption, various menstrual troubles, and parturition—in the last-named instance combined with Motherwort. "In chronic coughs, accompanied by spitting of blood," he tells us, "it will be found most excellent, either of itself or combined with other reliable remedies such as Lobelia, Marshmallow, Hyssop, etc."... horehound, black

Lobelia inflata. N.O. Campanulaceae.

Synonym: Indian Tobacco, Pukeweed, Emetic Weed.

Habitat: North America ; cultivated in Salt Lake City.

Features ? A biennial herb, in height from twelve to eighteen inches, the stem is angular and slightly hairy. One to three inches long, the leaves are alternate, sessile, and ovate-lanceolate, with small, whitish glands on the edge. The fruit is in the form of a flat, oval capsule, which contains ovate-oblong seeds about one eighth of an inch long, brown in colour, with a reticulated, pitted surface. The root is fibrous, and the plant bears a small blue, pointed flower. The taste is burning and acrid like tobacco, the odour slight. Part used ? Herb and seeds are used.

Action: Emetic, stimulant, antispasmodic, expectorant, and diaphoretic.

Lobelia inflata has for many years been one of the most widely discussed and hotly debated articles used in medicine. While many herbalists contend that it is the most valuable of all botanic remedies, official medicine in England classifies it as a poison. Herbalists who use Lobelia insist that it is most certainly not a poison, and that it can be administered by them in large doses with perfect safety. They use it chiefly as an emetic, and, as its administration brings about the prompt removal of accumulations of mucus, the action in bronchial complaints is speedy and beneficial. Coffin's comments in this connection are enthusiastic ? "Lobelia is decidedly the most certain and efficient emetic known, and is at the same time safe in its operations. Unlike most emetics from the mineral kingdom, it produces its specific effect without corroding the stomach or producing morbid irritation and inflammation of the mucous membrane of this organ, which are so common in the use of antimony, zinc, and the sulphate of copper. Lobelia may emphatically be said to 'operate in unison with the laws of life'."

In view of the controversy surrounding its use, the history of Lobelia is interesting. North American Indians had apparently long been acquainted

with its properties, but its first introduction to general use was due to the efforts of the famous American, Samuel Thomson. His disciple, Dr. Coffin, brought the herb to this country and used it extensively in his practice for over forty years, apparently with great success "in almost every form of disease, and from the tender infant to the aged," to quote Coffin himself. In both America and Britain herbalists have been tried on charges of causing death by administering Lobelia, but in no instance has a verdict been obtained against them.... lobelia

Tel: Bhucampakamu, Kondakaluva Mar: Bhuichampa

Importance: The tubers of Indian crocus are widely used as a local application for tumours, swellings and wounds. They are also given in gastric complaints. They help to remove blood clots and other purulent matter in the body. The juice of the tubers is given in dropsical affections of hands and feet, and of effusions in joints. The juice causes salivation and vomiting. In Ayurveda, the improvement formulations using the herb are Chyavanaprasam, Asokarishtam, Baladthatryaditailam, Kalyanakaghritham, etc. The drug “HALLAKAM” prepared from this is in popular use in the form of powder or as an ointment application to wounds and bruises to reduce swellings. It also improves complexion and cures burning sensation, mental disorders and insomnia (NRF, 1998; Sivarajan et al, 1994).

Distribution: The plant is distributed in the tropics and sub-tropics of Asia and Africa. The plant grows wild in shaded areas which are wet or humid, especially in forests in South India. It grows in gardens and is known for their beautiful flowers and foliage. It is also cultivated as an intercrop with other commercial crops.

Botany: Kaempferia rotunda Linn. belonging to the family Zingiberaceae is an aromatic herb with tuberous root-stalk and very short stem. Leaves are simple, few, erect, oblong or ovate- lanceolate, acuminate, 30cm long, 10cm wide, variegated green above and tinged with purple below. Flowers are fragrant, white, tip purple or lilac arranged in crowded spikes opening successively. The plant produces a subglobose tuberous rhizome from which many roots bearing small oblong or rounded tubers arise (Warrier et al, 1995).

Agrotechnology: The plant is a tropical one adapted for tropical climate. Rich loamy soil having good drainage is ideal for the plant. Laterite soil with heavy organic manure application is also well suited. Planting is done in May-June with the receipt of 4 or 5 pre-monsoon showers. The seed rate recommended is 1500-2000kg rhizomes/ha. Whole or split rhizome with one healthy sprout is the planting material. Well developed healthy and disease free rhizomes with the attached root tubers are selected for planting. Rhizomes can be stored in cool dry place or pits dug under shade plastered with mud or cowdung. The field is ploughed to a fine tilth, mixed with organic manure at 10-15t/ha. Seed beds are prepared at a size of 1m breadth and convenient length. Pits are made at 20cm spacing in which 5cm long pieces of rhizomes are planted. Pits are covered with organic manure. They are then covered with rotten straw or leaves. Apply FYM or compost as basal dose at 20 t/ha either by broadcasting and ploughing or by covering the seed in pits after planting. Apply fertilisers at the rate of 50:50:50 kg N, P2O5 and K2O/ha at the time of first and second weeding. After planting, mulch the beds with dry or green leaves at 15 t/ha. During heavy rainy months, leaf rot disease occurs which can be controlled by drenching 1% Bordeaux mixture. The crop can be harvested after 7 months maturity. Drying up of the leaves is the indication of maturity. Harvest the crop carefully without cutting the rhizome, remove dried leaves and roots. Wash the rhizome in water. They are stored in moisture-proof sheds. Prolonged storage may cause insect and fungus attack (Prasad et al, 1997).

Properties and activity: The tubers contain crotepoxide and -sitosterol. Tuber contains essential oil which give a compound with melting point 149oC which yielded benzoic acid on hydrolysis.

The tubers are acrid, thermogenic aromatic, stomachic, antiinflammatory, sialagogue, emetic, antitumour and vulnerary.... indian crocus

Verbascum thapsus. N.O. Scrophulariaceae.

Synonym: Great Mullein, Blanket Herb, or Candle Flower.

Habitat: Flourishes in sandy and gravelly waste ground, and is sometimes noticed under garden cultivation.

Features ? Reaching a height of four feet, the thick, erect, un-branched stem is

heavily coated with hairs. The large, flannel-like leaves are lanceolate-oblong below, the upper ones becoming decurrent, smaller, and more ovate in shape. Characteristic of the plant, leaves narrow at the base into two wings which pass down the stem, this feature enabling the medicinal Mullein to be distinguished from Verbascum nigrum and various other Mulleins. The flowers, which bloom in July and August, are built of five golden-yellow, rounded petals, and are densely packed on a woolly spike some foot or more in length.

Part used ? Leaves and flowers.

Action: Demulcent, pectoral and astringent.

A medicine is made by infusing 1 ounce in 1 pint of boiling water, the usual dose being a wineglassful, taken frequently. This is recommended mainly for chest coughs and certain other pulmonary complaints. Mullein has been considered a pile cure for several hundred years, and is still used for this purpose both internally and as a fomentation.

Culpeper preferred the root to the leaves and flowers, and advised it to be taken in wine. He tells us that this "is commended by Dioscorides against lasks and fluxes of the belly."... mullein

Hin: Asgandh, Punir Mal: Amukkuram

Tam: Amukkira

Tel: Vajigandha

Mar: Askandha

Guj: Ghoda

Kan: Viremaddinagaddi

Importance: Indian ginseng or Winter cherry is an erect branching perennial undershrub which is considered to be one of the best rejuvenating agents in Ayurveda. Its roots, leaves and seeds are used in Ayurvedic and Unani medicines, to combat diseases ranging from tuberculosis to arthritis. The pharmacological activity of the plant is attributed to the presence of several alkaloids and withaniols. Roots are prescribed in medicines for hiccup, several female disorders, bronchitis, rheumatism, dropsy, stomach and lung inflammations and skin diseases. Its roots and paste of green leaves are used to relieve joint pains and inflammation. It is also an ingredient of medicaments prescribed for curing disability and sexual weakness in male. Leaves are used in eye diseases. Seeds are diuretic. It is a constituent of the herbal drug ‘Lactare’ which is a galactagogue.

Aswagandha was observed to increase cell-mediated immunity, prevent stress induced changes in adrenal function and enhance protein synthesis. Milk fortified with it increases total proteins and body weight. It is a well known rejuvenating agent capable of imparting long life, youthful vigour and intellectual power. It improves physical strength and is prescribed in all cases of general debility. Aswagandha powder (6-12g) twice a day along with honey and ghee is advised for tuberculosis in Sushruta Samhita. It also provides sound sleep (Prakash, 1997).

Distribution: Aswagandha is believed to have oriental origin. It is found wild in the forests of Mandsaur and Bastar in Mandhya Pradesh, the foot hills of Punjab, Himachal Pradesh, Uttar Pradesh and western Himalayas in India. It is also found wild in the Mediterranean region in North America. In India it is cultivated in Madhya Pradesh, Rajastan and other drier parts of the country.

Botany: Aswagandha belongs to the genus Withania and family Solanaceae. Two species, viz, W. coagulans Dunal and W. somnifera Dunal are found in India. W. coagulans is a rigid grey under shrub of 60-120cm high. W. somnifera is erect, evergreen, tomentose shrub, 30-75cm in height. Roots are stout, fleshy, cylindrical, 1-2cm in diameter and whitish brown in colour. Leaves are simple, ovate, glabrous and opposite. Flowers are bisexual, inconspicuous, greenish or dull yellow in colour born on axillary umbellate cymes, comprising 5 sepals, petals and stamens each; the two celled ovary has a single style and a bilobed stigma. The petals are united and tubular. The stamens are attached to the corolla tube and bear erect anthers which form a close column or cone around the style. Pollen production is poor. The fruit is a small berry, globose, orange red when mature and is enclosed in persistent calyx. The seeds are small, flat, yellow and reniform in shape and very light in weight. The chromosome number 2n = 48.

The cultivated plants have sizable differences from the wild forms not only in their morphological characters but also in the therapeutical action, though the alkaloids present are the same in both (Kaul, 1957). Some botanists, therefore, described the cultivated plant distinct from wild taxa and have coined a new name W. aswagandha (Kaul, 1957) which is contested by Atal and Schwarting (1961).

Agrotechnology: Asgandh is a tropical crop growing well under dry climate. The areas receiving 600 to 750mm rainfall is best suited to this crop. Rainy season crop requires relatively dry season and the roots are fully developed when 1-2 late winter rains are received. Sandy loam or light red soils having a pH of 7.5- 8.0 with good drainage are suitable for its cultivation. It is usually cultivated on poor and marginal soils. Withania is propagated through seeds. It is a late kharif crop and planting is done in August. Seeds are either broadcast-sown or seedlings are raised in nursery and then transplanted. Seed rate is 10-12 kg/ha for broadcasting and 5kg/ha for transplanting. In direct sown crop plants are thinned and gap filling is done 25-30 days after sowing. Seeds should be treated with Dithane M-45 at 3g/kg of seeds before sowing. Seeds are sown in the nursery just before the onset of rainy season and covered with light soil. Seeds germinate in 6-7 days. When seedlings are six weeks old they are transplanted at 60cm in furrows taken 60cm apart. The crop is mainly grown as a rainfed crop on residual fertility and no manure or fertilizers are applied to this crop generally. However, application of organic manure is beneficial for realizing better yields. It is not a fertilizer responsive crop. One hand weeding 25-30 days after sowing helps to control weeds effectively. No serious pest is reported in this crop. Diseases like seedling rot and blight are observed. Seedling mortality becomes serious under high temperature and humid conditions. The disease can be minimized by use of disease free seeds and treatment with thiram or deltan at 3-4g/kg seed before sowing. Further, use of crop rotation, timely sowing and keeping field well drained also protect the crop. Spraying with 0.3% fytolan, dithane Z-78 or dithane M-45 will help controlling the disease incidence. Spraying is repeated at 15 days interval if the disease persists. Aswagandha is a crop of 150-170 days duration. The maturity of the crop is judged by the drying of the leaves and reddening of berries. Harvesting usually starts from January and continues till March. Roots, leaves and seeds are the economical parts. The entire plant is uprooted for roots, which are separated from the aerial parts. The berries are plucked from dried plants and are threshed to obtain the seeds. The yield is 400-500kg of dry roots and 50-75kg seeds per hectare.

Post harvest technology: The roots are separated from the plant by cutting the stem 1-2cm above the crown.

Roots are then cut into small pieces of 7-10cm to facilitate drying. Occasionally, the roots are dried as a whole. The dried roots are cleaned, trimmed, graded, packed and marketed. Roots are carefully hand sorted into the following four grades.

Grade A: Root pieces 7cm long, 1-1.5cm diameter, brittle, solid, and pure white from outside.

Grade B: Root pieces 5cm long, 1cm diameter, brittle, solid and white from outside.

Grade C: Root pieces 3-4cm long, less than 1cm diameter and solid. Lower grade: Root pieces smaller, hollow and yellowish from outside.

Properties and activity: Aswagandha roots contain alkaloids, starch, reducing sugar, hentriacontane, glycosides, dulcital, withaniol acid and a neutral compound. Wide variation (0.13-0.31%) is observed in alkaloid content. Majumdar (1955) isolated 8 amorphous bases such as withanine, somniferine, somniferinine, somnine, withananine, withananinine, pseudowithanine and withasomnine. Other alkaloids reported are nicotine, tropine, pseudotropine, 3, -tigloyloxytropane, choline, cuscudohygrine, anaferine, anahygrine and others. Free aminoacids in the roots include aspartic acid, glycine, tyrosine, alanine, proline, tryptophan, glutamic acid and cystine. Leaves contain 12 withanolides, alkaloids, glycosides, glucose and free amino acids. Berries contain a milk coagulating enzyme, two esterases, free amino acids, fatty oil, essential oil and alkaloids. Methods for alkaloid’s analysis in Asgandh roots have also been reported (Majumdar, 1955; Mishra, 1989; Maheshwari, 1989). Withania roots are astringent, bitter, acrid, somniferous, thermogenic, stimulant, aphrodisiac, diuretic and tonic. Leaf is antibiotic, antitumourous, antihepatotoxic and antiinflammatory. Seed is milk coagulating, hypnotic and diuretic.... indian ginseng

Importance: Indian Sarasaparilla or Country Sarasaparilla is a climbing slender plant with twining woody stems and a rust-coloured bark. The roots are useful in vitiated conditions of pitta, burning sensation, leucoderma, leprosy, skin diseases, pruritus, asthma, bronchitis, hyperdipsia, opthalmopathy, hemicrania, epileptic fits, dyspepsia, helminthiasis, diarrhoea, dysentery, haemorrhoids, strangury, leucorrhoea, syphilis, abcess, arthralgia, fever and general debility. The leaves are useful in vomiting, wounds and leucoderma. The stems are bitter, diaphoretic and laxative and are useful in inflammations, cerebropathy, hepatopathy, nephropathy, syphilis, metropathy, leucoderma, odontalgia, cough and asthma. The latex is good for conjunctivitis (Warrier et al, 1995). The important formulations using the drug are Saribadyasava, Pindataila, Vidaryadi lehya, Draksadi kasaya, Jatyadi ghrita, etc. (Sivarajan et al, 1994). The Hemidesmus root powdered and mixed with cow’s milk is given with much benefit in the case of strangury. In the form of syrup, it has demulcent and diuretic proportions. The root, roasted in plantain leaves, then beaten into a mass with cumin and sugar and mixed with ghee is a household remedy in genito-urinary diseases. The hot infusion of the root-bark with milk and sugar is a good alterative tonic especially for children in cases of chronic cough and diarrhoea (Nadkarni, 1998). It has been successfully used in the cure of venereal diseases where American Sarasaparilla (Aralia nudicaulis Linn.) has failed. Native doctors utilize it in nephritic complaints and for sore mouths of children (Grieve and Leyel, 1992).

Distribution: Hemidesmus is distributed throughout India, the Moluccas and Sri Lanka.

Botany: Hemidesmus indicus (Linn.) R. Br. syn. Periploca indica Linn. belongs to the family Asclepiadaceae. It is a perennial, slender, laticiferous, twining or prostrate, wiry shrub with woody rootstock and numerous slender, terete stems having thickened nodes. Leaves are simple, opposite, very variable from elliptic-oblong to linear-lanceolate, variegated with white above and silvery white and pubescent beneath. Flowers are greenish purple crowded in sub-sessile cymes in the opposite leaf-axils. Fruits are slender follicles, cylindrical, 10cm long, tapering to a point at the apex. Seeds are flattened, black, ovate-oblong and coma silvery white. The tuberous root is dark-brown, coma silvery white, tortuous with transversely cracked and longitudinally fissured bark. It has a strong central vasculature and a pleasant smell and taste (Warrier et al, 1995).

The Ayurvedic texts mention two varieties, viz. a krsna or black variety and a sveta or white variety (Aiyer, 1951) which together constitute the pair, Saribadvayam. The drug is known as Sariba. Svetasariba is H. indicus. Two plants, namely, Ichnocarpus fructescens (Apocynaceae) known as pal-valli in vernacular and Cryptolepis buchanani (Asclepidaceae) known as Katupalvalli (Rheeds, 1689) are equated with black variety or Krsnasariba (Chunekar, 1982; Sharma, 1983).

Agrotechnology: Hemidesmus is propagated through root cuttings. The root cuttings of length 3-5cm can be planted in polybags or in the field. They can be planted in flat beds or on ridges. Planting is done usually at a spacing of 50x20cm. Heavy application of organic manure is essential for good growth and root yield. Inorganic fertilizers are not usually applied. Frequent weeding and earthing up are required, as the plant is only slow growing. Provision of standards for twining will further improve the growth and yield of the plant.

Properties and activity: The twigs of the plant give a pregnane ester diglycoside named desinine. Roots give -sitosterol, 2-hydroxy-4-methoxy benzaldehyde, -amyrin, -amyrin and its acetate, hexatriacontane, lupeol octacosonate, lupeol and its acetate. Leaves, stem and root cultures give cholesterol, campesterol, -sitosterol and 16-dehydro-pregnenolone. Leaves and flowers also give flavonoid glycosides rutin, hyperoside and iso-quercitin (Husain et al,1992). “Hemidesmine”- a crystallizible principle is found in the volatile oil extracted from roots. Some suggest that it is only a stearoptene. It also contains some starch, saponin and in the suberous layer, tannic acid (Grieve and Leyel, 1992). The root is alterative, febrifuge, antileucorrhoeic, antisyphilitic, demulcent, diaphoretic, diuretic, tonic, galactogenic, antidote for scorpion-sting and snake-bite, antidiarrhoeal, blood purifier, antirheumatic and aperitive. Essential oil from root is anti-bacterial and the plant is antiviral (Husain et al, 1992).... indian sarasaparilla

Plumbago spp.

Plumbaginaceae

The genus Plumbago belonging to the family Plumbaginaceae is a popular and medicinally very important group of medicinal plants. Three species, namely P. rosea, P. zeylanica and P. auriculata have been identified. Among these P. rosea and P. zeylanica are important ones.

Plumbago, in general is an esteemed remedy for leucoderma and other skin diseases. The synonyms of fire like agnih, vahnih, etc. are attributed to this drug to indicate the very burning action of the root, causing blisters on the skin (daranah). The drug is used only after adequate curing and purification. Root is the officinal part and it enters into the composition of preparations like Citrakasavam, Dasamularista, Gulgulutiktaka kasaya, Yogarajachurna, etc.

Rosy-flowered leadwort or Fire plant is a native of Coromandel Coast. It is found throughout India, in moist situations as well as cultivated. The roots are useful in dyspepsia, colic, inflammations, cough, bronchitis, helmenthiasis, haemorrhoids, elephantiasis, chronic and intermittent fever, leprosy, leucoderma, ringworm, scabies, hepatosplenomegaly, amenorrhoea, odontalgia, vitiated conditions of vata, kapha and anaemia. It is a pretty subscandent perennial shrub with semi -woody striate stems and flexible branches. Leaves are simple, alternate oblong, short cuneate at the base passing into a very short amplexicaul, exauriculate, and reddish petiole. Flowers are bright red, arranged in long terminal spikes. The calyx ribs are covered with stipitate, bifarious and subsessile gland. Corolla tube is slender and four times as long as the calyx. The stout roots are cylindrical, irregularly bent, light yellowish brown with smooth surface having short transverse shallow fissures at the regions of the bents. A light yellowish juice excudes from the cut surface. A healthy plant may produce 18-20 stout roots (Warrier et al, 1995).

The chemical constituents include plumbagin and sitosterol glucoside. Clinical trials have demonstrated that plumbagin oil from P. indica is useful in common wart (Satyavati et al, 1987). The roots are acrid, astringent, thermogenic, anthelmintic, constipating, expectorant, antiinflammmatory, abortifacient, alterant, anti-periodic, carminative, digestive, sudorific, narcotic, gastric, nervous stimulant and rejuvenating. Root is a powerful sialogogue and vesicant.

White flowered Leadwort or Chitarak is found wild in peninsular India and mostly in West Bengal. Root is used externally in leprosy and other skin diseases or obstinate character, aphthae, abscesses, influenza, piles and anasarca. Juice is used externally in scabies and ulcers. One of the important preparations of Chitrak is “Yograjguggal”, prescribed for arthritis, rheumatism, etc. The other well known preparations are “Chitrak Adivati” and “ Chitraka Haritaki”. In Unani system it is an ingredient of “Aqaruva-i- Kabir”, “Hab Ashkhar”, “Ma’jun Baladur”, “Ma’jun Raig Mahi”, etc. It is a branched undershrub. Roots are long and tuberous. Stem is striate. Leaves are simple, alternate, short petioled, ovate or ovate-oblong, acute with entire or wavy margin, 7x3.8cm and glabrous. Flowers are white, arranged in terminal spikes. Calyx is tubular, glandular-hairy. Corolla tube is slender; limb rotate and 5 lobbed. Stamens are 5 on a disc. Style is slender with 5 stigmatic branches. Fruit is membranous capsule enclosed within the persistent calyx.

The roots of P. zeylanica have been exhaustively studied and naphthaquinones have been isolated, namely, plumbagin, 3-chlroplumbagin, droserone (Sidhu et al, 1971; Padhye et al, 1973), 3,3’-biplumbagin(Chitranone), zeylanone and iso-zeylanone and a coumarin, elliptinone (Sankaram et al, 1976, 1979). It also contains 1,2(3)-tetrahydro-3,3’-biplumbagin and plumbazeylanone. The leaf is antirheumatic. Root is appetiser, sudorific, relieves pain, vasicant, diuretic, caustic, antidiarrhoeal and expellent of phlegmatic tumours. Root is uterine stimulant. Root and fruits have antiimplantation activity. Plumbagin induces antiimplantation, has abortifacient and antiovulatory activity and causes selective testicular lesions in dogs. It is also a mitotic inhibitor. In lower concentration it behaves like a spindle, poison but in higher concentration it exhibits radiomimetic, nucleotoxic and cyclotoxic effects. It also has antibacterial, antifungal and anticoagulant activities and shows antagonism to amphetamine hyperactivity in mice.

3. P. auriculata Lam. syn. P. capensis

Eng: Blue flowered Leadwort;

Mal: Neelakotuveli

The blue flowered Leadwort is often grown in gardens throughout India (Moos, 1976; Chunekar, 1982; Sharma, 1983). It is a native of Cape Province in South Africa. It is a constituent of many Ayurvedic drugs (KAU, 1991). The plant is a subshrub growing to a height of 1-1.5m. Leaves are elliptic to obovate, 3-4 x 1.5-2cm. Inflorescence is a raceme of length 3-4cm. Corolla is blue to violet. Stamens are 5 in number. Flowers and fruits may be upto 12 in number (Matthew, 1995).

Agrotechnology: The plant is grown in tropical to subtropical ecosystems. Warm humid tropical climate is most suited. They come up well in almost all types of deep and well drained soils. It is propagated vegetatively by stem cuttings. Three stem cuttings of size 15cm long are planted in polybags of size 14x10cm. IAA and IBA treatments will improve rooting of cuttings. The land is to be ploughed well. About 4 tonnes of FYM are to be applied, mixed thoroughly and seed bed of size 50cm breadth, 1.5cm height and convenient length are to be prepared. On these beds pits are taken at a distance of 25cm and the rooted plants are transplanted from the polybags. Regular irrigation and weeding are to be carried out. In the second year with the onset of monsoon, seedbeds are again refreshed after adding about 4 tonnes of FYM. At the end of second year tubers are collected. Care should be taken to wear gloves, else the chemical plumbagin present in the roots will cause burning sensation. The collected tubers are washed, tied into bundles and marketed. Plumbago yields about 7-10t tubers/ha with good management (Prasad et al, 1997).... leadwort

Adhatoda beddomei

Acanthaceae

San:Vasaka, Vasa;

Hin:Adusa; Mal:Chittadalotakam;

Tam:Adutota; Tel:Addasaramu

Importance: Malabar nut or Adhatoda is a large evergreen glabrous perennial shrub, 1.2m in height. It is cultivated for medicinal uses, fencing, manure and as an ornamental plant in pots also. The shrub is the source of the drug vasaka well known in the indigenous systems of medicines for bronchitis. Vasaka leaves, flowers, fruits and roots are extensively used for treating common cold, cough, whooping cough, chronic bronchitis and asthma. It has sedative, expectorant, antispasmodic and anthelmintic actions. The juice of the leaves cures vomiting, thirst, fever, dermatosis, jaundice, phthisis, haematenesis and diseases due to the morbidity of kapha and pitta. The leaf juice is especially used in anaemia and haemorrhage, in traditional medicine. Flowers and leaves are considered efficacious against rheumatic painful swellings and form a good application to scabies and other skin complaints. Many ayurvedic medicines are traditionally prepared out of vasaka like vasarishtam, vasakasavam and vasahareethaki which are effective in various ailments of respiratory system. The drug VASA prepared from this plant forms an ingredient of preparations like Valiya rasnadi kasayam, Chyavanaprasam, Gulgulutiktakam ghrtam, etc. The alkaloid vasicinone isolated from the plant is an ingredient in certain allopathic cough syrups also.

Distribution: Vasaka is distributed all over India upto an altitude of 2000m. This plant grows on wasteland and sometimes it is cultivated also.

Botany: Adhatoda beddomei C.B.Clarke Syn. Justicia beddomei (Clark) Bennet belongs to the family Acanthaceae. This is a large glabrous shrub. Leaves are opposite, ovate, lanceolate and short petioled upto 15cm long, 3.75cm broad, main nerves about 8 pairs. Flowers are white with large bracts, flower heads short, dense or condensed spikes. Fruits are capsules with a long solid base.

Another plant Adhatoda zeylanica Medicus, syn. Adhatoda vasica Nees, Justicia adhatoda Linn. of the same genus is a very closely related plant which is most commonly equated with the drug VASA. This is seen growing wild almost throughout India while A. beddomei is seen more under cultivation. The latter is called Chittadalodakam because of its smaller stature, smaller leaves and flowers.

Agrotechnology: Vasaka is seen almost in all types of climate. It prefers loamy soils with good drainage and high organic content. It can be grown well both in hilly and plain lands. Commercial propagation is by using 15-20cm long terminal cuttings. This is either grown in polybags first, then in the field or planted directly. The plant is cultivated as a pure crop or mixed with plantation crops. The land is ploughed repeatedly to a good tilth and the surface soil is broken upto a depth of 15cm and mixed with fertilizers. The beds are prepared with 1m breadth and 3-4m length. The cuttings are planted during April-May into the beds at a spacing of 30x30cm. FYM is given at 5-10t/ha in the first year. Regular irrigation and weeding are necessary. Harvesting is at the end of second or third year. Roots are collected by digging the seedbeds. Stems are cut 15cm above the root. Stems and roots are usually dried and stored.

Properties and activity: Leaves yield essential oil and an alkaloid vasicine. Roots contain vasicinol and vasicinone. Roots also contain vasicoline, adhatodine, anisotine and vasicolinone. Several alkaloids like quinazoline and valicine are present in this plant.

The plant is bitter, astringent, refrigerant, expectorant, diuretic, antispasmodic, febrifuge, depurative, styptic and tonic. Vasicine is bronchodilator, respiratory stimulant and hypotensive in action, uterine stimulant, uterotonic, abortifacient comparable with oxytocin and methyligin. Uterotonic action of vasicine is mediated through the release of prostaglandins.... malabar nut

Plantago major. N.O. Plantaginaceae.

Synonym: Also called Ripple Grass and Way bread, the herb is known in Scotland as "Soldiers," and in America and New Zealand as "Englishman's Foot"—Plantain being supposed always to follow in his footsteps.

Habitat: Spreads in meadows, along the borders of fields, and in the hedgerows.

Features ? Springing from the root, the large leaves are ovate, blunt, and contract abruptly at the base. When, however, the plant is found in open fields the leaves tend to grow upwards on channelled stalks. The very small, brownish-purple flowers grow close together on a spike about five inches long. The plant is astringent to the taste, and odourless.

Part used ? The leaves are used medicinally.

Action: Alterative and diuretic.

Combined with other agents, they are of some value in piles and diarrhea. The fresh juice will give relief from insect and nettle stings.

John Skelton writes that Plantain "makes one of the best ointments for piles I know of."... plantain

Importance: Periwinkle or Vinca is an erect handsome herbaceous perennial plant which is a chief source of patented cancer and hypotensive drugs. It is one of the very few medicinal plants which has a long history of uses as diuretic, antidysenteric, haemorrhagic and antiseptic. It is known for use in the treatment of diabetes in Jamaica and India. The alkaloids vinblastine and vincristine present in the leaves are recognized as anticancerous drugs. Vinblastine in the form of vinblastin sulphate is available in market under the trade name “VELBE” and Vincristine sulphate as “ONCOVIN” (Eli Lilly). Vinblastine is used in combination with other anticancer agents for the treatment of lymphocytic lymphoma, Hodgkin’s disease, testicular carcinoma and choriocarcinoma. Vincristine is used in acute leukemia, lymphosarcoma and Wilm’s tumour. Its roots are a major source of the alkaloids, raubasine (ajmalicine), reserpine and serpentine used in the preparation of antifibrillic and hypertension-relieving drugs. It is useful in the treatment of choriocarcinoma and Hodgkin’s disease-a cancer affecting lymph glands, spleen and liver. Its leaves are used for curing diabetes, menorrhagia and wasp stings. Root is tonic, stomachic, hypotensive, sedative and tranquilliser (Narayana and Dimri,1990).

Distribution: The plant is a native of Madagascar and hence the name Madagascar Periwinkle. It is distributed in West Indies, Mozambique, South Vi etnam, Sri Lanka , Philippines and Australia. It is well adapted to diverse agroclimatic situations prevalent in India and is commercially cultivated in the states of Tamil Nadu, Karnataka, Gujarat, Madhya Pradesh and Assam. USA, Hungary, West Germany, Italy, Netherlands and UK are the major consumers.

Botany: Catharanthus roseus (Linn.) G.Don.

syn. Vinca rosea Linn. belongs to the family Apocynaceae. It is an erect highly branched lactiferous perennial herb growing up to a height of one metre. Leaves are oblong or ovate, opposite, short-petioled, smooth with entire margin. Flowers are borne on axils in pairs. There are three flower colour types , pink, pink-eyed and white. Calyx with 5 sepal, green, linear, subulate. Corolla tube is cylindrical with 5 petals, rose-purple or white with rose-purple spot in the centre; throat of corolla tube hairy, forming a corona-like structure. The anthers are epipetalous borne on short filaments inside the bulging distal end of corolla tube converging conically above the stigma. Two characteristic secretary systems, namely a column like nectarium on both sides of pistil and a secretory cringulam circling the papillate stigma with a presumed role in pollination - fecundation process are present. Ovary bicarpellary, basally distinct with fused common style and stigma. The dehiscent fruit consists of a pair of follicles each measuring about 25 mm in length and 2.3 mm in diameter, containing up to thirty linearly arranged seeds with a thin black tegumen. On maturity, the follicles split along the length dehiscing the seeds.

Agrotechnology: Periwinkle grows well under tropical and subtropical climate. A well distributed rainfall of 1000 mm or more is ideal. In north India the low winter temperatures adversely affect the crop growth. It can grow on any type of soil ,except those which are highly saline, alkaline or waterlogged. Light soils, rich in humus are preferable for large scale cultivation since harvesting of the roots become easy.

Catharanthus is propagated by seeds. Fresh seeds should be used since they are short-viable. Seeds can be either sown directly in the field or in a nursery and then transplanted. Seed rate is 2.5 kg/ha for direct sowing and the seeds are drilled in rows 45 cm apart or broadcasted. For transplanted crop the seed rate is 500gm/ha. Seeds are sown in nursery and transplanted at 45x 30cm spacing after 60 days when the seedlings attain a height of 15-20cm Nursery is prepared two months in advance so that transplanting coincides with the on set of monsoons. Application of FYM at the rate of 15 t/ha is recommended. An alternate approach is to grow leguminous green manure crops and incorporate the same into the soil at flowering stage. Fertilisers are recommended at 80:40:40 kg N:P2O5:K2O/ha for irrigated crop and 60:30:30 kg/ha for rainfed crop. N is applied in three equal splits at planting and at 45 and 90 days after planting. 4 or 5 irrigations will be needed to optimise yield when rainfall is restricted. Fortnightly irrigations support good crop growth when the crop is grown exclusively as an irrigated crop. Weeding is carried out before each topdressing. Alternatively, use of fluchloraline at 0.75 kg a.i. /ha pre-plant or alachlor at 1.0 kg a.i. per ha as pre-emergence to weeds provides effective control of a wide range of weeds in periwinkle crop. Detopping of plants by 2cm at 50% flowering stage improves root yield and alkaloid contents. No major pests, other than Oleander hawk moth, have been reported in this crop. Fungal diseases like twig blight (top rot or dieback) caused by Phytophthora nicotianae., Pythium debaryanum, P. butleri and P. aphanidermatum; leaf spot due to Alternaria tenuissima, A. alternata, Rhizoctonia solani and Ophiobolus catharanthicola and foot-rot and wilt by Sclerotium rolfsii and Fusarium solani have been reported. However, the damage to the crop is not very serious. Three virus diseases causing different types of mosaic symptoms and a phyllody or little leaf disease due to mycoplasma -like organisms have also been reported; the spread of which could be checked by uprooting and destroying the affected plants.

The crop allows 3-4 clippings of foliage beginning from 6 months. The flowering stage is ideal for collection of roots with high alkaloid content. The crop is cut about 7 cm above the ground and dried for stem, leaf and seed. The field is irrigated, ploughed and roots are collected. The average yields of leaf, stem and root are 3.6, 1.5and 1.5 t/ha, respectively under irrigated conditions and 2.0, 1.0 and 0.75t/ha, respectively under rainfed conditions on air dry basis. The harvested stem and roots loose 80% and 70% of their weight, respectively. The crop comes up well as an undercrop in eucalyptus plantation in north India. In north western India a two year crop sequence of periwinkle-senna-mustard or periwinkle-senna- coriander are recommended for higher net returns and productivity (Krishnan,1995).

Properties and activity: More than 100 alkaloids and related compounds have so far been isolated and characterised from the plant. The alkaloid contents in different parts show large variations as roots 0.14-1.34%, stem 0.074-0.48%, leaves 0.32-1.16%, flowers 0.005-0.84%, fruits 0.40%, seeds 0.18% and pericarp 1.14% (Krishnan et al, 1983). These alkaloids includes monomeric indole alkaloids, 2-acyl indoles, oxindole, -methylene indolines, dihydroindoles, bisindole and others. Dry leaves contain vinblastine (vincaleucoblastine or VLB) 0.00013-0.00063%, and vincristine (leurocristine or LC) 0.0000003-0.0000153% which have anticancerous activity (Virmani et al, 1978). Other alkaloids reported are vincoside, isovincoside (strictosidine), catharanthine, vindolinine, lochrovicine, vincolidine, ajmalicine (raubasine), reserpine, serpentine, leurosine, lochnerine, tetrahydroalstonine, vindoline, pericalline, perivine, periformyline, perividine, carosine, leurosivine, leurosidine and rovidine. The different alkaloids possessed anticancerous, antidiabetic, diuretic, antihypertensive, antimicrobial, antidysenteric, haemorrhagic, antifibrillic, tonic, stomachic, sedative and tranquillising activities.... periwinkle

Cochlearia officinalis. N.O. Cruciferae.

Synonym: Known in some parts as Spoonwort.

Habitat: Grows freely along the sea shore.

Features ? The smooth, shiny stem is angular and much branched, with ovate leaves which become sessile upwards; further roundish, kidney-shaped, stalked leaves grow from the roots. Clusters of white, cruciform flowers bloom in May. The taste is pungent and cress-like.

Scurvygrass is a powerful antiscorbutic, but, as scurvy, like other "deficiency" diseases, is now prevented and cured by purely dietetic methods, the herb is but rarely used. It is, however, given a place here both for its historic interest and for the striking way in which it exemplifies the curative potency of non-poisonous herbs.

The Medical Research Council, in its publication Vitamins ? A Survey of

Present Knowledge, says:

"Scurvygrass (Cochlearia officinalis) . . . figures largely in old records of scurvy cures among mariners. Thus Bachstron in 1734 tells the following story ? 'A sailor in the Greenland ships was so over-run and disabled with scurvy that his companions put him into a boat and sent him on shore, leaving him there to perish without the least expectation of recovery. The poor wretch had quite lost the use of his limbs ; he could only crawl about the ground. This he found covered with a plant which he, continually grazing like a beast of the field, plucked up with his teeth. In a short time he was by this means perfectly recovered, and upon his returning home it was found to be the herb scurvy grass.' (Rendering given by Lind [1757, p.

395].)."

When a well-authenticated case such as this is quoted by such a body as the Medical Research Council it should not be difficult to believe that other agents used in the herbal practice may be equally effective in illnesses not at present included in the official list of "deficiency diseases."... scurvygrass

Importance: It is a large deciduous tree, with simple leaves and white fragrant flowers.

Strychnos is highly toxic to man and animals producing stiffness of muscles and convulsions, ultimately leading to death. However, in small doses it can also serve as efficacious cure forms of paralysis and other nervous disorders. The seeds are used as a remedy in intermittent fever, dyspepsia, chronic dysentery, paralytic and neuralgic affections, worms, epilepsy, chronic rheumatism, insomnia and colic. It is also useful in impotence, neuralgia of face, heart disease, spermatorrhoea, skin diseases, toxins, wounds, emaciation, cough and cholera. Leaves are applied as poultice in the treatment of chronic wounds and ulcers and the leaf decoction is useful in paralytic complaints. Root and root bark used in fever and dysentery (Nadkarni, 1982; Kurup et al, 1979).

Distribution: The plant is distributed throughout India in deciduous forests up to 1200m. It is also found in Sri Lanka, Siam, Indochina and Malaysia.

Botany: Strychnos nux-vomica Linn. is a large tree belonging to the family Loganiaceae. Leaves are simple, opposite, orbicular to ovate, 6-11.5x6-9.5cm, coriaceous, glabrous, 5 nerved, apex obtuse, acute or apiculate, transverse nerves irregular and inconspicuous. Inflorescence is many flowered terminal cymes, 2.5-5cm across. Bracts (5mm) and bracteoles (1.5mm) small. Flowers are white or greenish white and fragrant. Calyx 5 lobed, pubescent and small (2mm). Corolla salver shaped, tube cylindrical slightly hairy near the base within and greenish white, tube much elongate than the lobes. Tube 7mm and lobes 2.5mm long. Lobes 5 and valvate. Stamens 5, filaments short, 0.1mm long. Anthers 1.5mm subexerted, linear oblong. Ovary 1.5 mm, pubescent, 2 celled, ovules one to many. Style 9mm, stigma capitate. Fruit is a berry, 5-6cm diameter, globose, indehiscent, thick shelled, orange red when ripe with fleshy pulp enclosing the seeds. Seeds 1-many, discoid, compressed, coin like, concave on one side and convex on the other, covered with fine grey silky hairs.

The leaf fall is during December (do not shed all the leaves at a time) and new foliage appears in February. Flowering is during March - April and fruiting during May - December. Fruits take about 8-9 months to mature.

Properties and activity: Strychnine and brucine are the most important and toxic alkaloids present in the plant. They occur not only in the seeds but also in roots, wood, bark, fruit pulp and hard fruit shells. The minor alkaloids present in the plant are vomicine, -colubrine, -colubrine, pseudostrychnine and N-methyl-sec-pseudobrucine (novacine). Loganin a glycoside is also present (Warnat, 1932; Martin et al, 1953; Guggisberg et al, 1966; Bisset and Chaudhary, 1974). Chatterji and Basa (1967) reported vomicine as the major constituent alkaloid along with unidentified alkaloid in leaves and identified another alkaloid kajine (N-methyl pseudostrychnine) from the leaves of very young plants.

Root bark of S. nux-vomica yeilded 4-hydroxy-3-methoxy strychnine, 4 hydroxy strychine, nor-macusine, a new alkaloid 12 , 13 dihydro-12 -hydroxy isostrychnine named protostrychnine (Baser et al, 1979) methoxy strychnine, and mavacurine (Guggisberg et al, 1966). Leaves and root bark also yeilded 11 new alkaloids. 10-hydroxy strychnine, 3-12-dihydroxystrychnine, 12-hydroxy–11- methoxy strychnine, 3-12-dihydroxy- 11-methoxy strychnine,12-hydroxy strychnine-N- oxide 12-hydroxy-11-methoxy strychnine- N-oxide-19,20–dihydro isostrychnine, 16 , 17 dihydro-17 -hydroxy isostrychnine, O- methyl-macusine B, 16-epi-o-methyl–macusine B and normelinone B (Baser and Bisset, 1982).

De and Datta (1988) isolated 5 tertiary indole alkaloids viz. strychnine, brucine, vomicine, icajine and novacine from S.nux-vomica flowers. Bisset et al (1989) isolated and identified two phenolic glycosides salidroside and cuchiloside – a compound consisting of salidroside and an attached xylose unit, from the fruit of S.nux-vomica.

Rodriguez et al (1979) isolated an indole alkaloid from the seeds of S. nux- vomica and identified as a 3-methoxy icajine. A new alkaloid 15-hydroxy strychnine has been isolated from the seeds and the structure of the alkaloid established by spectroscopic data (Galeffi et al, 1979). Cai et al (1990a) isolated 4 new alkaloids isobrucine, isobrucine N-oxide, isostrychnine N-oxide and 2 hydroxy–3-methoxy strychnine from the heat treated seeds of S. nuxvomica and the structure of the alkaloids were determined by 13 CNMR (Cai et al, 1994). Cai et al (1990 b) studied the changes in the alkaloid composition of the seeds during drug processing. Saily et al (1994) determined the mineral elements in Strychnos nux-vomica. Corsaro et al (1995) reported polysaccharides from the seeds of Strychnos species.

Seeger and Neumann (1986) reviewed the physico-chemical characteristics, occurrence, identification, utilisation, poisoning, toxicity, kinetics, differential diagnosis and therapeutic uses of strychnine and brucine. Aspergillus niger, A. flavus and Pencillium citrinum showed regular association with Strychnos seeds and effectively deteriorated the alkaloid content of the seeds (Dutta, 1988; Dutta and Roy, 1992). Nicholson (1993) described the history, structure and synthesis of strychnine which occur in the seeds of S. nux-vomica. Rawal and Michoud (1991) developed a general solution for the synthesis of 2- azabicyclo (3.3.1) nonane substructure of Strychnos alkaloids.

Villar et al (1984) and Hayakawa et al (1984) developed HPLC method for the analysis of strychnine and brucine. Graf and Wittliner (1985), Kostennikova (1986) and Gaitonde and Joshi (1986) suggested different methods for the assay of strychnine and brucine. Biala et al, (1996) developed new method for the assay of alkaloids in S. nux- vomica.

The seeds are bitter, acrid, alexeteric, aphrodisiac, appetiser, antiperiodic, anthelmintic, digestive, febrifuge, emmenagogue, purgative, spinal, respiratory and cardiac stimulant and stomachic. The bark is bitter, and tonic and febrifuge (Nadkarni, 1954; Kurup et al, 1979; Warrier et al, 1996).

The quarternery alkaloid from the root bark of the Sri Lankan plant exhibited muscle-relaxant activity (Baser and Bisset, 1982). Antimicrobial activity of indole alkaloid isolated from the Strychnos nux-vomica was studied by Verpoorte et al, 1983. Shukla et al (1985) evaluated the efficacy of Rasnadigugglu compound consisting of S. nux-vomica, on rheumatoid arthritis and found to be effective in reducing inflammatory oedoma and rheumatoid arthritis. It also exhibited analgesic activity. A compound Unani formulation containing S. nux-vomica significantly attenuated withdrawal intensity in morphine dependent rats (Zatar et al, 1991). Shahana et al (1994) studied the effect of Unani drug combination (UDC) having Strychnos nux-vomica on the abstinence syndrome in moderately and severely morphine dependent rats. The UDC strikingly suppressed the abstinence syndrome was seen to possess central depressant and analgesic action.

Melone et al (1992) reported brucine-lethality in mice. Panda and Panda (1993) and Satyanarayanan et al (1994) reported antigastric ulcer activity of nux vomica in Shay rats. Banerjee and Pal (1994) reported the medicinal plants used by the tribals of plain land in India for hair and scalp preparation and S. nux-vomica being used to cure alopecia (baldness) by the tribals. Tripathi and Chaurasia (1996) studied the effect of S. nux-vomica alcohol extract on lipid peroxidation in rat liver.... strychnine tree
