San: Danti;

Hin: Danti;

Mal: Danti, Nagadanti;

Tam: Nakatanti;

Tel: Nelajidi

Importance: Danti or Nagadanti is a stout undershrub with numerous flowers. Root, which is the officinal part, is used in abdominal pain, constipation, calculus, general anasarca, piles, helminthic manifestations, scabies, skin disorders, suppurative ulcers and diseases caused by the morbidity of kapha and pitta. Root paste is applied to painful swellings and piles. Leaves cure asthma and seeds are used in snakebite (Kurup et al, 1979; Sharma, 1983). The drug forms an important constituent of preparations like Dantyarishta, Dantiharitakileham, Kaisoraguggulu gulika, etc.(Sivarajan et al, 1994).

Distribution: The plant is found throughout the sub-Himalayan tracts from Kashmir to Khasi Hills. It is common in West Bengal, Bihar and Central and Peninsular India.

Botany: Baliospermum montanum (Willd.) Muell-Arg. syn. B. axillare Bl., B. polyandrum Wt. belongs to the family Euphrobiaceae. It is a stout under-shrub 0.9-1.8m in height with herbaceous branches from the roots. Leaves are simple, sinuate-toothed, upper ones small, lower ones large and sometimes palmately 3-5 lobed. Flowers are numerous, arranged in axillary racemes with male flowers above and a few females below. Fruits are capsules, 8-13mm long and obovoid. Seeds are ellipsoid smooth and mottled (Warrier et al,1993).

Agrotechnology: The tropical plant is suited to almost all soils. It can be cultivated either as pure crop or intercrop. It is propagated vegetatively by cuttings. About 15-20cm long rooted cuttings are used for planting. Pits of size 50cm cube are to be taken at 3m spacing and filled with dried cowdung, sand and top soil and formed into a mound. On these mounds, rooted cuttings are to be planted at 2 cuttings/mound. Cuttings establish within one month. Weeding is to be carried out at this time. Application of organic manure after every 6 months is beneficial. Irrigation during summer months is preferable. The plant is not attacked by any serious pests or diseases. Roots can be collected at the end of second year. The roots are to be cut and dried in sun before marketing. The yield is about one tonne root/ha (Prasad et al,1997).

Properties and activity: Roots contain diterpenes, baliospermin, montanin, phorbol-12-deoxy-13-O-palmitate, phorbol-12-deoxy-16-hydroxy-13-O-palmitate and phorbol-12-deoxy-5 -hydroxy-13 – myristate (Ogura et al, 1978). Alcoholic extract of plant showed hypotensive activity in experimental animals (Bhakuni et al, 1971). Antilukaemic and cytotoxic activities have been demonstrated in the esters of both 12-deoxyphorbol and 12-deoxy-16-hydroxyphorbol, isolated from B. montanum (King-horn, 1979). The roots are acrid, thermogenic, purgative, antiinflammatory, anodyne, digestive, anthelmintic, diuretic, diaphoretic, rubefacient, febrifuge and tonic. Seed is purgative, stimulant, rubefacient and antidote for snakebite. Seed oil is antirheumatic. Leaf is antiasthmatic and wound healing. Root and seed oil is cathartic and antidropsical. Stem is anti-dontalgic.... nagadanti

Croton tiglium

Euphorbiaceae

San: Jepalah, Dantibijah

Hin: Jamalgota

Ben: Jaypal Mal: Nirvalam

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

Leaves—used externally in skin diseases (ringworm, eczema, boils, swellings); rubefacient, topically stimulant.

The seeds contain hallucinogenic ergoline alkaloids, the main ones being ergine and isoergine. EtOH (50%) extract of seeds exhibits hypotensive activity. (Seeds of all species of Argyreia contain ergoline alkaloids and are hypotensive.) Leaves of Argyreia sp. contain sitosterol and are antiphlogistic.

In Indian medicine, A. speciosa is not used as a single drug for sexual disorders in men, but as a supporting drug for exerting its antiphlogistic, spasmolytic and hypotensive actions on the central nervous system. The drug, in itself, did not show anabolic- cum-androgen-like or spermogenetic activity experimentally.

Ipomoea petaloidea Chois and Ipo- moea biloba Forskofthe Convolvulacae family are also used as Vriddhadaaru.

In Western herbal medicine, Hawaiian Baby Woodrose is equated with Argyreia nervosa (synonym Argyreia speciosa; grows in Florida, California and Hawaii). The seed is used for pain relief and as a hallucinogen.

The seeds contain hallucinogens including ergonovine, isoergine (isoly- sergic acid amide) and ergine (lysergic acid amide). Four to eight seeds are equivalent to 10-100 mcg of LSD, a potent serotonin-1A (5-HT1A) agonist. The effects last 6-8 h. (Natural Medicines Comprehensive Database, 2007.)

Dosage: Root—3-5 g powder.

(L.) Boiss.

Synonym: Sinapis alba L.

Family: Cruciferae; Brassicaceae.

Habitat: Native of Europe and West Asia. Cultivated in North India as a crop.

English: White Mustard.

Ayurvedic: Siddhaartha, Shveta Sarshapa, Sarshapa-Gaura.

Unani: Khardal Safed.

Siddha/Tamil: Venkadugu.

Folk: Safed Raai.

Action: Stimulant to gastric mucosa, increases pancreatic secretions; emetic (used in narcotic poisoning), diaphoretic, rubefacient. (As a counter-irritant it increases flow of blood to a specific area.) Used externally as a poultice in bronchitis, pleurisy, intercostal neuralgia, chilbains.

Seeds contain glucosinolates. Sinalbin in B. alba and sinigrin in B. juneja oil are toxic constituents. The oil with toxic constituents should be avoided in gastrointestinal ulcers and kidney disorders. When moistened, sinigrin in the seeds is degraded to allyl isothiocyanate, a potent irritant volatile oil. (Francis Brinker.)

Glucosinolates are goitrogenic. Excessive consumption of Brassica sp. vegetables may alter absorption of thyroid hormone in G2 tract. (Sharon M. Herr.)... brassica alba

Habitat: Cultivated as an oil-yielding crop.

English: Field Mustard, Turnip Rape.

Ayurvedic: Sarshapa, Siddhaartha.

Unani: Sarson.

Siddha/Tamil: Kadugu.

Action: Stimulant, diuretic, emetic, rubefacient, counter-irritant. Used externally for bronchitis and rheumatic pains (increases flow of blood to a specific area). Powdered seeds are used as a tea for colds, influenza and fever.

The seeds contain glycosinolates (the derivatives are responsible for tox- icity). The concentration of the major glucosinolate, gluco-napin, varies from 0.64 to 1.8% in the oil-free meal of Indian brassicas. The glucosinolates in rapeseed meal split upon enzymatic hydrolysis to produce glucose, potassium, hydrogen sulphate and a sulphur- containing compound which undergoes intramolecular rearrangement to give rise to the antinutritional factors, isothiocyanates or thiocyanates.

The volatile oil of mustard is given internally in colic; in overdoses it is highly poisonous and produces gastro- enteric inflammations. It is employed externally as a liniment for rheumatic pains.

Adulteration of mustard oil with argemone oil (Argemone mexicana is frequently found growing in brassica fields), by accident or by design, has led to the widespread epidemics of dropsy and glaucoma due to an alkaloid sanguinarine.

Black mustard contains sinigrin, which on hydrolysis by enzyme my- rosin, produces allyisothiocynate; the white mustard contains sinalbin, which produces p-hydroxybenzyl isothiocy- nate. Mucilage contains sinapine.

Key application: Externally in catarrhal diseases of the respiratory tract and muscular rheumatism; internally in hypotonic circulatory regulation disorders, Catarrhal diseases of the respiratory tract. (German Commission E.)

The plant contains a volatile oil comprising camphor, safrole, linalool, eugenol and terpeneol. It also contains lignans (including secoisosolari- ciresinol dimethyl ether and kusunoki- ol). Safrole is thought to be carcinogenic.

The leaf oil is a natural source of linalool (94.9%); also contained cit- ronellal (2.4%).

Camphor in concentration of 500 mcg/ml completely inhibits the growth of vibro parahaemolyticus, one of the causative agents of diarrhoea and dysentery. Ethanolic extract (50%) of fruits show antibacterial activity against several Gram-positive and Gram-negative bacteria. The essential oil from the plant possesses antifungal activity against many fungi. Camphor is toxic at 2-20 g.

Action: Juice from petiole—styptic, rubefacient. Juice of corn—used in alopaecia.

The leaves contain flavones, api- genin and luteolin, also anthocyanins. Leaves cause severe irritation in mouth. Cooked leaves are a source of dietary fibre for diabetics helping in lowering post-prandial blood glucose level. A significant increase in total lipids, total cholesterol and triglyceride levels was observed in hypercholesterolaemic rats when fed with dried leaf powder.

The pressed juice of the petioles is used as an astringent and styptic. All parts of the plant show an acridity. The acridity is removed by boiling and by addition of baking soda.

From the tubers two dihydroxys- terols, besides beta-sitosterol and stig- masterol, have been isolated. Five novel aliphatic compounds have been reported. Trypsin inhibitors are isolated from the tubers.

The total amino acids recorded in the tubers range from 1380 to 2397 mg/ 100 g. The lysine concentration was relatively low. Besides starch, the tubers contain natural polysaccharides with 56% neutral sugars and 40% anionic components. Steamed corms contain 30% starch and 3% sugar.... colocasia esculenta

Siddha/Tamil: Nervaalam.

Action: Cathartic, rubefacient, irritant. Used in ascites, anasarca, dropsy and enlargement of abdominal viscera.

The seed oil is purgative. It produces severe symptoms of toxicity when taken internally or applied externally to the skin.

Croton oil showed tumour-promoting activity on mouse skin. The skin irritant and tumour promoting diterpene esters of the tigliane type (phorbol esters) and toxins have been isolated from the seeds. (In China, where the herb is employed for the treatment of gastro-intestinal disturbances, the highest incidence of naso- pharyngeal cancer has been reported.) 1 ml oil is usually fatal. Phorbols (terpenoids) from nonvolatile oil are toxic. Crotin, a toxic albuminous substance, is not extracted in the oil. The plant caused haematuria and swelling of lymph glands in animals.

Dosage: Seed—6-12 mg powder. (API Vol. IV.)... croton tiglium

Unani: Zarambaad. Siddha/Tamil: Kichhilikkizhangu.

Action: Carminative, stomaehie, gastrointestinal stimulant, diuretic, expectorant, demulcent, rubefacient. Used in flatulence and dyspepsia. Fresh root is used for checking lecorrhoeal discharge; also for blood purification. Zedoary's effect on digestive organs is similar to ginger but milder.

Along with other therapeutic applications, The Ayurvedic Pharmacopoeia of India indicated the use of the rhizome in goiter.

The rhizomes are a source of Shoti Starch, used as a food for babies and convalescents, recovering from chronic stomatitis. It is cooling and demulcent.

Zedoary, dried rhizomes, contains a number of terpenoids, including curcumene, curcumenone, curdione, curcumenol. Curzerenone, furanoger- menone, germacrone, germacrone epoxide; a volatile oil (1.0-1.5%) resembling ginger oil, and starch (50%).

Zedoary is thought to stimulate bile production (due to sesquiterpene ke- tones) and gall bladder emptying (due to cucuminoid constituents).

The sesquiterpenes, germacrone, germacrone epoxide, curzerenone and curcumenol showed CNS depressant properties. Curzerenone also showed a potent protective effect against induced lesions in rats. Both curz- erenone and curcumenol showed a moderate analgesic action.

The terpenoid furanogermenone exhibits antiallergic activity. (Powdered zedoary, mixed with fructose, is used as an antiallergant in Japan.)

Curcumenol and curdione are shown to possess tumour-inhibiting property. The rhizome is used in China for extradural haematomas and certain types of tumours. It has been reported in China that zedoary reduced cervical cancer and increased the effects of chemotherapy and radiotherapy.

The volatile oil of zedoary exhibits antimicrobial and antifungal activity. The antifungal constituent of the oil has been reported as methyl-p-methoxy- cinnamate.

Ruta graveolens has been included among unapproved herbs by German Commission E.

The herb contains a volatile oil, with 2-undecanone (30.73) 2-nona- none (18.06), 2-nonyl acetate (11.03), psoralen (1.28) and bergapten and xan- thotoxin (7.24%); rutin (about 2%). The flavonoids include quercetin; cou- marins include bergapten, daphnore- tin, isoimperatorin, naphthoherniarin, psoralen, pangelin, rutamarin, rutarin, scopoletin and umbelliferone. Tissue culture of the plant gave furacridone alkaloids. Tissue culture of the root gave gravacridondiol and its glucoside.

The spasmolytic activity of the herb is attributed to the presence of bergapten, xanthotoxin and the essential oil. Anti-inflammatory and antitumour activity is due to rutin. The furo- coumarins are responsible for the herb's phototoxicity.

The herb is hepatotoxic, and is con- traindicated in kidney diseases and bleeding disorders. (Sharon M. Herr.) Maximum safe level is 0.001% for Rue and 0.0002% for the oil. (Natural Medicines Comprehensive Database, 2007.)... ruta graveolens

Pimenta dioica

FAMILY: Myrtaceae

SYNONYMS: P. officinalis, pimento, pimenta, Jamaica pepper.

GENERAL DESCRIPTION: An evergreen tree which reaches about 10 metres high and begins to produce fruit in its third year. Each fruit contains two kidney-shaped green seeds which turn glossy black upon ripening.

DISTRIBUTION: Indigenous to the West Indies and South America, it is cultivated extensively in Jamaica, Cuba and, to a lesser degree, in Central America. Imported berries are distilled in Europe and America.

OTHER SPECIES: Four other varieties of pimento are found in Venezuela, Guyana and the West Indies which are used locally as spices.

HERBAL/FOLK TRADITION: Used for flatulent indigestion and externally for neuralgic or rheumatic pain. Pimento water is used as a vehicle for medicines which ease dyspepsia and constipation since it helps prevent griping pains. It is used extensively as a domestic spice – allspice is so called because it tastes like a combination of cloves, juniper berries, cinnamon and pepper.

ACTIONS: Anaesthetic, analgesic, anti-oxidant, antiseptic, carminative, muscle relaxant, rubefacient, stimulant, tonic.

EXTRACTION: Essential oil by steam distillation from 1. the leaves, and 2. the fruit. The green unripe berries contain more oil than the ripe berries, but the largest percentage of oil is contained in the shell of the fruit. An oleoresin from the berries is also produced in small quantities.

CHARACTERISTICS: 1. Pimenta leaf oil is a yellowish-red or brownish liquid with a powerful sweet-spicy scent, similar to cloves. 2. Pimenta berry oil is a pale yellow liquid with a sweet warm balsamic-spicy bodynote (middle note) and fresh, clean top note. It blends well with ginger, geranium, lavender, opopanax, labdanum, ylang ylang, patchouli, neroli, oriental and spicy bases.

PRINCIPAL CONSTITUENTS: Mainly eugenol, less in the fruit (60–80 per cent) than in the leaves (up to 96 per cent), also methyl eugenol, cineol, phellandrene and cryophyllene among others.

SAFETY DATA: Eugenol irritates the mucous membranes, and has been found to cause dermal irritation. Pimenta leaf and berry oil should therefore be used with care in low dilutions only.

AROMATHERAPY/HOME: USE:

Circulation, muscles and joints: Arthritis, fatigue, muscle cramp, rheumatism, stiffness etc. ‘Used in tiny amounts … in a massage oil for chest infections, for severe muscle spasm to restore mobility quickly, or where extreme cold is experienced.’1

Respiratory System: Chills, congested coughs, bronchitis.

Digestive System: Cramp, flatulence, indigestion, nausea.

Nervous System: Depression, nervous exhaustion, neuralgia, tension and stress.

OTHER USES: Used in aromatic carminative medicines; as a fragrance component in cosmetics and perfumes, especially soaps, aftershaves, spicy and oriental fragrances. Both leaf and berry oil are used extensively for flavouring foods, especially savoury and frozen foods, as well as alcoholic and soft drinks.... allspice

Betula lenta

FAMILY: Betulaceae

SYNONYMS: B. capinefolia, cherry birch, southern birch, mahogany birch, mountain mahogany.

GENERAL DESCRIPTION: A graceful tree about 25 metres high which has a pyramidal shape while young. It has bright green leaves and a dark reddish-brown aromatic bark, which is broken into plates or patches.

DISTRIBUTION: Native to southern Canada and southeastern USA; produced mainly in Pennsylvania.

OTHER SPECIES: There are numerous species of birch, spanning several continents, such as black birch (B. nigra) found in North America. Not to be confused with the European white birch (B. alba), which produces birch tar oil used in chronic skin diseases.

HERBAL/FOLK TRADITION: The cambium (the layer directly under the bark) is eaten in the spring, cut into strips like vermicelli. The bark, in the form of an infusion, is used as a general stimulant and to promote sweating. As a decoction or syrup, it is used as a tonic for dysentery and is said to be useful in genito-urinary irritation. The flavour of wintergreen and birch bark, in the form of a tea, was popular with the American Indians and European settlers. More recently, this has been translated into a preference for ‘root beer’ flavourings.

ACTIONS: Analgesic, anti-inflammatory, antipyretic, antirheumatic, antiseptic, astringent, depurative, diuretic, rubefacient, tonic.

EXTRACTION: Essential oil by steam distillation of the bark macerated in warm water.

CHARACTERISTICS: Colourless, pale yellow or reddish tinted liquid with an intense, sweet-woody, wintergreen-like scent.

PRINCIPAL CONSTITUENTS: Almost entirely methyl salicylate (98 per cent), produced during the maceration process. It is almost identical in composition to wintergreen oil.

SAFETY DATA: Methyl salicylate, the major constituent, is not exactly toxic but very harmful in concentration.’ It can be absorbed through the skin, and fatal poisoning via this route has been reported.’. ’ It is also classed as an enviromental hazard or marine pollutant.

AROMATHERAPY/HOME: USE None.

OTHER USES: Limited use as a counter-irritant in anti-arthritic and antineuralgic ointments and analgesic balms. Limited use as a fragrance component in cosmetics and perfumes; extensively used as a flavouring agent, especially ‘root beer’, chewing gum, toothpaste, etc. (usually very low-level use).... birch, sweet

Citrus bergamia

FAMILY: Rutaceae

SYNONYM: Citrus aurantium subsp. bergamia.

GENERAL DESCRIPTION: A small tree, about 4.5 metres high with smooth oval leaves, bearing small round fruit which ripen from green to yellow, much like a miniature orange in appearance.

DISTRIBUTION: Native to tropical Asia. Extensively cultivated in Calabria in southern Italy and also grown commercially on the Ivory Coast.

OTHER SPECIES: Not to be confused with the herb bergamot or bee balm (Monarda didyma).

HERBAL/FOLK TRADITION: Named after the Italian city of Bergamo in Lombardy, where the oil was first sold. The oil has been used in Italian folk medicine for many years, primarily for fever (including malaria) and worms; it does not feature in the folk tradition of any other countries. However, due to recent research in Italy, bergamot oil is now known to have a wide spectrum of applications, being particularly useful for mouth, skin, respiratory and urinary tract infections.

ACTIONS: Analgesic, anthelmintic, antidepressant, antiseptic (pulmonary, genito-urinary), antispasmodic, antitoxic, carminative, digestive, diuretic, deodorant, febrifuge, laxative, parasiticide, rubefacient, stimulant, stomachic, tonic, vermifuge, vulnerary.

EXTRACTION: Essential oil by cold expression of the peel of the nearly ripe fruit. (A rectified or terpeneless oil is produced by vacuum distillation or solvent extraction.)

CHARACTERISTICS: A light greenish-yellow liquid with a fresh sweet-fruity, slightly spicy-balsamic undertone. On ageing it turns a brownish-olive colour. It blends well with lavender, neroli, jasmine, cypress, geranium, lemon, chamomile, juniper, coriander and violet.

PRINCIPAL CONSTTTUENTS Known to have about 300 compounds present in the expressed oil: mainly linalyl acetate (30–60 per cent), linalol (11–22 per cent) and other alcohols, sesquiterpenes, terpenes, alkanes and furocoumarins (including bergapten, 0.30–0.39 per cent).

SAFETY DATA: Certain furocoumarins, notably bergapten, have been found to be phototoxic on human skin; that is, they cause sensitization and skin pigmentation when exposed to direct sunlight (in concentration and in dilution even after some time!). Extreme care must be taken when using the oil in dermal applications – otherwise a rectified or ‘bergapten-free’ oil should be substituted. Available information indicates it to be otherwise non-toxic and relatively non-irritant.

AROMATHERAPY/HOME: USE

Skin Care: Acne, boils, cold sores, eczema, insect repellent and insect bites, oily complexion, psoriasis, scabies, spots, varicose ulcers, wounds.

Respiratory System: Halitosis, mouth infections, sore throat, tonsillitis.

Dryobalanops aromatica

FAMILY: Dipterocarpaceae

SYNONYMS: D. camphora, Borneo camphor, East Indian camphor, Baros camphor, Sumatra camphor, Malayan camphor.

GENERAL DESCRIPTION: The camphora tree grows to a great height, a majestic tree often over 25 metres high, with a thick trunk up to 2 metres in diameter. Borneol is a natural exudation found beneath the bark in crevices and fissures of some mature trees (about 1 per cent); young trees produce only a clear yellow liquid known as ‘liquid camphor’.

DISTRIBUTION: Native to Borneo and Sumatra.

OTHER SPECIES: To be distinguished from the Japanese or Formosa type of camphor, more commonly used in Europe, which is relatively toxic. See also Botanical Classification section.

HERBAL/FOLK TRADITION: Borneol has long been regarded as a panacea by many Eastern civilizations, especially in ancient Persia, India and China. It was used as a powerful remedy against plague and other infectious diseases, stomach and bowel complaints. In China it was also used for embalming purposes. ‘It is mentioned by Marco Polo in the thirteenth century and Camoens in 1571 who called it the “balsam of disease”.’. It is valued for ceremonial purposes in the east generally, and in China particularly for funeral rites. Its odour repels insects and ants, and it is therefore highly regarded as timber for the construction of buildings.

ACTIONS: Mildly analgesic, antidepressant, antiseptic, antispasmodic, antiviral, carminative, rubefacient, stimulant of the adrenal cortex, tonic (cardiac and general).

EXTRACTION: The borneol is collected from the tree trunk in its crude crystalline form (the natives test each tree first by making incisions in the trunk to detect its presence). The so-called ‘oil of borneol’ is extracted by steam distillation of the wood.

CHARACTERISTICS: Watery white to viscous black oil depending upon the amount of camphor which it contains, with a distinctive, sassafras-like, camphoraceous odour.

PRINCIPAL CONSTITUENTS: The crude is made up of mainly cl-borneol which is an alcohol, not a ketone (like Japanese camphor). The oil contains approx. 35 per cent terpenes: pinene, camphene, dipentene; 10 per cent alcohols: d-borneol, terpineol; 20 per cent sesquiterpenes, and 35 per cent resin.

SAFETY DATA: Non-toxic, non-sensitizing, dermal irritant in concentration.

GENERAL DESCRIPTION: A beautiful, tall, evergreen tree, up to 90 metres high. The young trees have bluish-green oval leaves while the mature trees develop long, narrow, yellowish leaves, creamy-white flowers and a smooth, pale grey bark often covered in a white powder.

DISTRIBUTION: Native to Tasmania and Australia. Mainly cultivated in Spain and Portugal, also Brazil, California, Russia and China. Very little of this oil now comes from its native countries.

OTHER SPECIES: There are over 700 different species of eucalyptus, of which at least 500 produce a type of essential oil. Many have been extracted simply for experimental purposes, and research is still being carried out with regard to the different constituents of each oil. In general, they can be divided into three categories. 1. The medicinal oils containing large amounts of cineol (or eucalyptol), such as the blue gum, but increasingly the blue malee (E. polybractea), the narrow-leaved peppermint (E. radiata var. australiana) and the gully gum (E. smithii). 2. The industrial oils containing mainly piperitone and phellandrene, such as the peppermint eucalyptus (E. piperita), grey peppermint (E. radiata var. phellandra) and increasingly the broad-leaved peppermint (E. dives var. Type). 3. The perfumery oils containing mainly citronellal, such as the lemon-scented eucalyptus (E. citriodora). See also Botanical Classification section.

HERBAL/FOLK TRADITION: A traditional household remedy in Australia, the leaves and oil are especially used for respiratory ailments such as bronchitis and croup, and the dried leaves are smoked like tobacco for asthma. It is also used for feverish conditions (malaria, typhoid, cholera, etc.) and skin problems like burns, ulcers and wounds. Aqueous extracts are used for aching joints, bacterial dysentery, ringworms, tuberculosis, etc. and employed for similar reasons in western and eastern medicine. The wood is also used for timber production in Spain.

FAMILY: Lamiaceae (Labiatae)

SYNONYMS: L. hybrida, L. hortensis, bastard lavender.

GENERAL DESCRIPTION: A hybrid plant developed by crossing true lavender (L. angustifolia) with spike lavender or aspic (L. latifolia). Due to its hybrid nature, lavandin has a variety of forms: in general, it is a larger plant than true lavender, with woody stems. Its flowers may be blue like true lavender, or greyish like aspic.

DISTRIBUTION: A natural lavandin occurs in the mountainous regions of southern France where both parent plants grow wild, though at different altitudes. Still mainly cultivated in France, but also Spain, Hungary, Yugoslavia and Argentina.

OTHER SPECIES: There are cultivars of lavender, such as ‘Dwarf Blue’, ‘Hidcote Pink’ and ‘Bowles Early’; there are also many cultivars of lavandin such as ‘Grey Hedge’, ‘Silver Grey’ and ‘Alba’. For further information see entries on true lavender and spike lavender; also the Botanical Classification section.

HERBAL/FOLK TRADITION: Sixty years ago, when A Modern Herbal was written by Mrs Grieve, lavandin was still unknown, so it does not have a long history of therapeutic use. Its properties seem to combine those of the true lavender and aspic.

ACTIONS: See true lavender.

EXTRACTION: Essential oil by steam distillation from the fresh flowering tops; it has a higher yield of oil than either true lavender or aspic. (A concrete and absolute are also produced by solvent extraction.)

CHARACTERISTICS: A colourless or pale yellow liquid with a fresh camphoraceous topnote (which should not be too strong in a good quality oil), and a woody herbaceous undertone.

The so-called cotton lavender (Santolina chamaecyparissus) and the sea lavender (Statice caroliniana) belong to different botanical families.

HERBAL/FOLK TRADITION: Lavender has a well-established tradition as a folk remedy, and its scent is still familiar to almost everyone. It was used to ‘comfort the stomach’ but above all as a cosmetic water, an insect repellent, to scent linen, and as a reviving yet soothing oil ‘The essential oil, or a spirit of lavender made from it, proves admirably restorative and tonic against faintness, palpitations of a nervous sort, weak giddiness, spasms and colic ... A few drops of lavender in a hot footbath has a marked influence in relieving fatigue. Outwardly applied, it relieves toothache, neuralgia, sprains and rheumatism. In hysteria, palsy and similar disorders of debility and lack of nerve power, lavender will act as a powerful stimulant.’.

Zingiber cassumunar

FAMILY: Zingiberaceae

SYNONYMS: Z. montanum, Z. cassumunar ‘Roxburgh’, Z. purpureum ‘Roscoe’, cassumunar ginger.

GENERAL DESCRIPTION: The root of this tropical perennial plant is tuberous, with long fleshy fibres and jointed appendages, much like ginger but slightly larger. The fresh rhizome, which is yellow inside, has a cool, green, camphoraceous, spicy-warm scent. The stem is made of green leaf sheathes which are grass-like with brownish-purple pointed shoots bearing pale yellow flowers.

DISTRIBUTION: Native to Thailand, Indonesia and India: it is now commonly found throughout Asia. Since plai is an important medicinal plant in Thailand, there are many regions where plai is cultivated and there are now at least three native varieties or sub-species found in Thailand.

OTHER SPECIES: There are several sub-species (and essential oil chemotypes) of plai depending on the location of the plant from which it has been extracted. Essential oil produced from rhizomes grown in the north-west region is the most typical from Thailand and contains almost as much terpinen-4-ol as tea tree oil. Terpinen-4-ol has been well researched, and is to known to activate white blood cells: it also has significant antibacterial, antiviral and antifungal properties. Oil produced from the central region contains more sabinene. Zingiber cassumunar is a close relative of ginger and galangal, both of which are used to produce essential oils.

HERBAL/FOLK TRADITION: Zingiber cassumunar is widely used in folklore remedies as a single plant or as component of herbal recipes in Thailand and many Asian countries for the treatments of conditions, such as inflammation, sprains and strains, rheumatism and muscular pain. Although it is derived from the same plant family as ginger (Zingiber officinale), it does not possess the classic warming effect common to ginger. Instead, plai has a cooling action on inflamed areas, making it an excellent choice for treating injuries, post-operative pain and all types of muscular and joint pain such as torn muscles and ligaments as well as conditions such as arthritis and rheumatism. For this reason, plai has long been regarded by Thai massage therapists as one of the most essential oils to have at their disposal. Although generally diluted with a carrier oil, it can be applied directly to the skin when treating areas of severe pain or inflammation that are close to the surface of the skin. It is reported to ease pain for up to 16–20 hours – it is even used by Thai boxers for pain relief!

Used in skin care, the oil exhibits good antioxidant properties and is used in Thai culture to treat stretch marks and scars; also to heal wounds. Plai herbal compound is used traditionally in the form of a poultice and decoction for the treatment of a range of digestive disorders including colic, constipation, diarrhoea, flatulence, nausea heartburn. Zingiber cassumunar is also a traditional Thai remedy for respiratory conditions, including asthma, catarrh, colds and coughs, fever and influenza.

ACTIONS: Analgesic, antioxidant, antibacterial, antimicrobial, antihistamine, antineuralgic, antifungal, anti-inflammatory, antiseptic, antispasmodic, antitoxic, antiviral, carminative, digestive, diuretic, febrifugal, laxative, rubefacient, rejuvenating, stimulant, tonic, vermifuge.

EXTRACTION: Steam distilled from the fresh rhizome (roots) of the Plai plant (Zingiber cassumunar).

CHARACTERISTICS: The oil is a pale amber colour with a fresh, herbaceous, spicy-green scent and a resinous, slightly floral undertone. It will blends well with black pepper, bergamot, ginger, grapefruit, lemongrass, lime, jasmine, lavender, neroli, petitgrain, rosemary, sandalwood and tea tree.

PRINCIPAL CONSTITUENTS: The main active chemical constituents of the oil are terpinen-4-ol (up to 49 per cent) sabinene (up to 45 per cent), DMPBD (up to per cent), g-terpinene and a-terpinene – depending on the source of the oil.

DISTRIBUTION: Native to Spain and the Mediterranean region; now found throughout Asia Minor, Algeria, Turkey, Tunisia, Israel, the USA, Russia, China and central Europe. The oil is mainly produced in Spain but also in France, Israel, Greece, Morocco, Algeria, Germany and the USA.

OTHER SPECIES: There are numerous varieties of thyme – the common thyme is believed to have derived from the wild thyme or mother-of-thyme (T. serpyllum), which is also used to produce an essential oil called serpolet, similar in effect to the common thyme oil.

Another species used for the production of the so-called red thyme oil is particularly the Spanish sauce thyme (T. zygis), a highly penetrating oil good for cellulitis, sports injuries, etc. (although, like the common thyme, it is a skin irritant). Other species used for essential oil production include lemon thyme (T. citriodorus), a fresh scented oil good for asthma and other respiratory conditions, safe for children. Spanish marjoram (T. Mastichina) is actually botanically classified as a variety of thyme, with which it shares many common properties, despite its common name. Spanish marjoram contains mainly 1,8-cineole (up to 75 per cent) and linalool (up to 20 per cent), so therapeutically has much in common with eucalyptus, being well suited to treating viral and bacterial respiratory infections. See also Botanical Classification section.

HERBAL/FOLK TRADITION: One of the earliest medicinal plants employed throughout the Mediterranean region, well known to both Hippocrates and Dioscorides. It was used by the ancient Egyptians in the embalming process, and by the ancient Greeks to fumigate against infectious illness; the name derives from the Greek thymos meaning ‘to perfume’. It is also a long-established culinary herb, especially used for the preservation of meat.

It has a wide range of uses, though in Western herbal medicine its main areas of application are respiratory problems, digestive complaints and the prevention and treatment of infection. In the British Herbal Pharmacopoeia it is indicated for dyspepsia, chronic gastritis, bronchitis, pertussis, asthma, children’s diarrhoea, laryngitis, tonsillitis and enuresis in children.

ACTIONS: Anthelmintic, antimicrobial, antioxidant, antiputrescent, antirheumatic, antiseptic (intestinal, pulmonary, genito-urinary), antispasmodic, antitussive, antitoxic, aperitif, astringent, aphrodisiac, bactericidal, balsamic, carminative, cicatrisant, diuretic, emmenagogue, expectorant, fungicidal, hypertensive, nervine, revulsive, rubefacient, parasiticide, stimulant (immune system, circulation), sudorific, tonic, vermifuge.

EXTRACTION: Essential oil by water or steam distillation from the fresh or partially dried leaves and flowering tops. 1. ‘Red thyme oil’ is the crude distillate. 2. ‘White thyme oil’ is produced by further redistillation or rectification. (An absolute is also produced in France by solvent extraction for perfumery use.)

CHARACTERISTICS: 1. A red, brown or orange liquid with a warm, spicy-herbaceous, powerful odour. 2. A clear, pale yellow liquid with a sweet, green-fresh, milder scent. It blends well with bergamot, lemon, rosemary, melissa, lavender, lavandin, marjoram, Peru balsam, pine, etc.

PRINCIPAL CONSTITUENTS: Thymol and carvacrol (up to 60 per cent), cymene, terpinene, camphene, borneol, linalol; depending on the source it can also contain geraniol, citral and thuyanol, etc.

There are many chemotypes of thyme oil: notably the ‘thymol’ and ‘carvacrol’ types (warming and active); the ‘thuyanol’ type (penetrating and antiviral); and the milder ‘linalol’ or ‘citral’ types (sweet-scented, non-irritant).

SAFETY DATA: Red thyme oil, serpolet (from wild thyme), ‘thymol’ and ‘carvacrol’ type oils all contain quite large amounts of toxic phenols (carvacrol and thymol). They can irritate mucous membranes, cause dermal irritation and may cause sensitization in some individuals. Use in moderation, in low dilution only. They are best avoided during pregnancy.

White thyme is not a ‘complete’ oil and is often adulterated. Lemon thyme and ‘linalol’types are in general less toxic, non-irritant, with less possibility of sensitization – safe for use on the skin and with children.

Pinus palustris and other Pinus species

FAMILY: Pinaceae

SYNONYMS: Terebinth, therebentine, gum thus, gum turpentine, turpentine balsam, spirit of turpentine (oil).

GENERAL DESCRIPTION: ‘Gum turpentine’ is a term loosely applied to the natural oleoresin formed as a physiological product in the trunks of various Pinus, Picea and Abies species. Turpentine refers both to the crude oleoresin (a mixture of oil and resin) and to the distilled and rectified essential oils.

DISTRIBUTION: All over the world. The largest producer is the USA, also Mexico, France, Portugal, Spain, Greece, Scandinavia, New Zealand, Tasmania, India, China, the USSR, etc.

OTHER SPECIES: Apart from the longleaf pine (Pinus palustris), which is the leading source of American gum turpentine, other sources in the USA include the slash pine (P. elliottii) and the Mexican white pine (P. ayacahuite). In India the chir pine (P. roxburghii); in Tasmania the lodgepole pine (P. contorta var. latifolia); in China the masson or Southern red pine (P. massoniana); in Europe and Scandinavia the Scotch pine (P. sylvestris) and the sea pine (P. pinaster), as well as many others. See Botanical Classification section.

HERBAL/FOLK TRADITION: Known to Galen and Hippocrates for its many applications, especially with regard to pulmonary and genito-urinary infections, digestive complaints and externally as a treatment for rheumatic or neuralgic pain and skin conditions. In China the oleoresin has been used (both internally and externally) for centuries for excess phlegm, bronchitis, rheumatism, stiff joints, toothache, boils, sores, ringworm and dermatitis.

The turpentine essence or spirit of turpentine is said to be four times more active than the crude turpentine.

ACTIONS: Analgesic, antimicrobial, antirheumatic, antiseptic, antispasmodic, balsamic, diuretic, cicatrisant, counter-irritant, expectorant, haemostatic, parasiticide, rubefacient, stimulant, tonic, vermifuge.

EXTRACTION: Essential oil by steam (or water) distillation from the crude oleoresin, then rectified. ‘It has to be purified because it is viscous, coloured and acidic.’.

CHARACTERISTICS: A colourless, water white mobile liquid with a fresh, warm balsamic, familiar odour.

PRINCIPAL CONSTITUENTS: Mainly alphapinene (approx. 50 per cent), betapinene (25–35 per cent) and carene (20–60 per cent) in the American oils. In European oils the alpha pinene can constitute up to 95 per cent – constituents vary according to source.

SAFETY DATA: Environmental hazard – marine pollutant. Relatively non-toxic and non-irritant; possible sensitization in some individuals. Avoid therapeutic use or employ in moderation only.

AROMATHERAPY/HOME: USE Use with care for:

Skin care: Boils, cuts, fleas, insect repellent, lice, ringworm, scabies, wounds.

Circulation muscles and joints: Arthritis, gout, muscular aches and pains, rheumatism, sciatica.

Respiratory system: Bronchitis, catarrh, whooping cough.

Genito-urinary system: Cystitis, leucorrhoea, urethritis.

Immune system: Colds.

Nervous system: Neuralgia.

OTHER USES: Used in many ointments and lotions for aches and pains; and in cough and cold remedies. Neither oil nor oleoresin is used in perfumery work, although resin derivatives are used as fixative agents and in pine and industrial perfumes. Mainly known as a paint and stain remover, solvent and insecticide. Also used as a starting material for the production of terpineol, etc.... turpentine
