Importance: Common rue or Garden rue also known as Herb of Grace due to its service in the Roman Catholic Church for sprinkling the holy water among the congregation, is an aromatic perennial herb. The plant is useful in vitiated conditions of kapha and vata, strangury, fever, flatulence, colic, amenorrhoea, epilepsy and hysteria. The oil acts as a stimulant for uterine and nervous systems. The fresh leaves are used for rheumatalgia. The juice obtained from the leaves is given to children for helminthic infections and is good for odontalgia and otalgia (Warrier et al, 1996). The dried leaves, powdered and combined with aromatics, are given as a remedy for dyspepsia and with the fresh leaves a tincture is made which is used as an external remedy in the first stages of paralysis (Nadkarni, 1998).

Distribution: The plant is a native of South Europe and it is found in subtropical countries. It is commonly cultivated in Indian gardens.

Botany: Ruta chalepensis Linn.syn. R. graveolens Linn. var. angustifolia Sensu Hook. f. belongs to the family Rutaceae. It is an aromatic perennial herb growing upto 75cm height. Leaves are compound, shortly petiolate with ultimate segments oblong or obovate-oblong. Flowers are yellow. Fruits are capsules and shortly pedicelled (Warrier et al, 1996).

Agrotechnology: The plant is suited to areas which are about 1000m above mean sea level and with moderate rainfall and sunlight. The plant can be propagated either by seeds or stem cuttings. Seeds are to be sown in seedbeds. Stem cuttings of length 20-25cm are to be planted in polybags for rooting. About 3-4 months old seedlings can be transplanted to pots and harvested when plants attain 6-8 months age. In highlands land is to be ploughed to a fine tilth, mixed with organic manure and seedlings are to be transplanted at a spacing of 45cm between plants. Irrigation is essential during summer months. Regular weeding is to be done. The plant is not attacked by any serious pests and diseases. Harvesting commences from sixth month onwards. The economic part is the whole plant and the oil extracted from it (Prasad et al, 1997).

Properties and activity: Roots contain coumarins-xanthyletin and (-)-byakangelicin. The alkaloids are rutacridone-epoxide, gravacridonol and its monomethyl ether, gravacridonchlorine, furacridone, 1-hydroxy-3-methoxy-N-methylacridone, iso-gravacridonechlorine, dictamine, r-fragarine and skimmianine. Skimmianine is also present in leaves and stem. Leaves and stem also contain graveolinine (1-methyl-2(3’,4’-methylenedioxyphenol)-4-methoxy- quinoline). Aerial parts give coumarins bergapten, xanthotoxin and psoralen. Coumarin- imperatin has also been reported from the plant. Herb contains alkaloids such as kokusagenine, rutamine(methylgraveoline) and graveoline(1-methyl-2(3’,4’- methylenedioxyphenyl)-4-quinoline). Tissue culture of the plant gives furacridone alkaloids-1-hydroxyrutacridone-epoxide, rutagravin and gravacridonol. Gravacridondiol and its glucoside have been obtained from the root tissue culture. The essential oil from leaves, stem and root yielded aliphatic ketones including 2-nonanone (10-35%), undecyl-2-acetate (0.5-15%), 2-nonyl acetate (trace-10%), nonylacetate, nonanol, 2-nonylpropionate, 2- nonylpropionate, 2-undecanol and its esters. The oil from roots gave pregeijerene also.

The plant is spasmolytic which is due to the presence of bergapten, xanthotoxin, the essential oil and a coumarin. It is also antispasmodic, emmenagogue, irritant, abortifacient and anti-bacterial. Leaf is analgesic, antirheumatic, antihysteric and anthelmintic (Husain et al, 1992).... garden rue

Botany: The genus Strobilanthes belonging to the family Acanthaceae consists of 3 species namely,

S. ciliatus Nees.,syn. Nilgirianthus ciliatus (Nees) Bremek

S. auriculatus Nees. and

S. callisus Nees.

S. ciliatus is a slender shrub with subquandrangular white dotted dark green or purple stems and branches. Leaves are dark green, elliptic, accuminate at both ends, serrate, glabrous with 6-7 pairs of main nerves. Flowers are white to lilac, arranged in axillary slender glabrous spikes. Fruits are very rarely formed. Adventitious roots arise from a few basal nodes also. The main roots as well as the nodal roots are used as raw drugs (Warrier et al, 1995).

Agrotechnology: Strobilanthes prefers silty loam soil, mixed with sand, for good growth. It grows abundantly in river banks, lowlands and plains. The best season of planting is May-June. The field is to be ploughed to a fine tilth and mixed with 5-7t/ha of FYM/compost/dried cowdung. Seed beds of size 3m length, 0.5m width and 15cm height are to be made in which 10cm long stem cuttings are to be planted at a spacing of 30cm between plants. Rooting occurs within 20 days. Two weedings should be carried out at 2 months and 4 months after planting, followed by organic manure application. Irrigation is not a must but during summer months it is beneficial. The plant is not attacked by any serious pests or diseases. Harvesting can be done at the end of the second year. For this the plants are to be cut, roots dug out and collected. Roots are to be washed well, dried in sun and marketed. Roots, leaves and bark constitute the economic parts (Prasad et al, 1997).

Properties and activity: The leaves and stem yield essential oil which is of good medicinal value. The roots are bitter, sweet, thermogenic, emollient, diuretic, febrifuge, diaphoretic, depurative, antiinflammatory and tonic.

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

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

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.

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

It is found in marshes, wild or cultivated, ascending the Himalayas upto 1800m in Sikkim. It is plentiful in marshy tracts of Kashmir and Sirmoor, in Manipur and Naga Hills.

Botany: Acorus calamus Linn. belonging to the family Araceae is a semi -aquatic rhizomatous perennial herb. Rhizome is creeping, much branched, cylindrical or slightly compressed, light brown or pinkish brown externally, white and spongy within. Leaves are bright green, distichous, ensiform, base equitant, thickened in the middle and with wavy margins. Flowers are light brown and densely packed in sessile cylindric spadix. Fruits are oblong, turbinate berries with a pyramidal top. Seeds are few and pendant from the apex of the cells (Warrier et al, 1993).

Another species belonging to the genus Acorus is A. gramineus Soland, the roots of which are used in tonic, antiseptics and insecticidal preparations (Chopra et al, 1956).

Agrotechnology: Acorus is a hardy plant found growing from tropical to subtropical climates. It needs a good and well distributed rainfall throughout the year. It needs ample sunlight during the growth period as well as after harvest for drying the rhizomes. It may be cultivated in any good but fairly moist soil. It is usually grown in areas where paddy can be grown. It comes up well in clayey soils and light alluvial soils of river bank. The field is laid out and prepared exactly as for rice, irrigated sufficiently and after ploughing twice, watered heavily and again ploughed in the puddle. Sprouted rhizome pieces are used for planting and pressed into the mud at a depth of about 5cm at a spacing of 30x30cm. The rhizomes are planted in such a way that the plants in the second row comes in between the plants of the first row and not opposite to them. FYM is to be applied at 25t/ha. Fertilisers are applied at 25:50:60 kg N:P2O5:K2O/ha/yr. Whole of FYM and 1/3 of N, P2O5 and K2O are to be added in the field during March - April as a basal dose. The remaining 2/3 of nutrients is to be given in two equal split doses at 4 months and 8 months after planting. The field is to be regularly irrigated. About 5 cm of standing water is to be maintained in the field in the beginning. Later, it is to be increased to 10 cm as the plant grows. The field is to be regularly weeded. About 8 weedings are to be carried out in all. At each weeding the plants are pressed into the soil. The plant is attacked by mealy bugs. Both shoot and root mealy bugs can be controlled by spraying the shoot and drenching the roots of grown up plants with 10 ml Methyl parathion or 15ml Oxydemeton methyl or 20ml Quinalphos in 10 litres of water. The crop is ready for harvest at the end of first year. The field is to be dried partially so that sufficient moisture is left in the soil to facilitate deep digging. The leaves start turning yellow and dry, indicating maturity. The rhizome will be at a depth of 60cm and having about 30-60cm spread. Therefore, harvesting is to be done carefully. The rhizomes are to be cut into 5-7.5cm long pieces and all the fibrous roots are to be removed. Yield of rhizome is about 10t/ha (Farooqi et al, 1991).

Properties and Activity:Rhizomes, roots and leaves yield essential oil. The important constituents of the Indian oil are asarone and its -isomer. Other constituents are and -pinene, myrcene, camphene, p-cymene, camphor and linalool, sesquiterpenic ketones like asarone, calamone, calacone, acolamone, iso-acolamone, acoragermacrone, epishyobunone, shyobunone and iso- shyobunone. Alcohol present is preisocalamendiol. Sesquiterpene hydrocarbons like elemene, elemane and calarene are also present. Tricyclic sesquiterpenes present are caryophyllene, humulene, guaiene, S-guaizulene, arcurcumene, -cadinene, cadinane, calamenene, calacorene, dihydrocalacorene(calamenene), cadalene and selinene. Roots yield acoric acid as a main constituent in addition to choline. Plant also yields a flavone diglycoside- luteolin 6,8-C-diglucoside.

-asarone is the ma jor constituent of essential oil from rhizome (Dandiya et al, 1958,1959; Raquibuddoula, 1967).

Rhizome is insecticidal, pisicidal, spasmolytic, hypothermic, CNS active and analgesic. Essential oil is anticonvulsant. Rhizome is acrid, bitter, thermogenic, aromatic, intellect promoting, emetic, laxative, carminative, stomachic, anthelmintic, emmenagogue, diuretic, alexeteric, expectorant, anodyne, antispasmodic, aphrodisiac, antiinflammatory, sudorific, antipyretic, sialagogue, insecticidal, tranquillizer, sedative, analgesic, antithermic, antiasthmatic, hypotensive, respiratory depressant, aperitive and tonic.... sweet flag
