Action: Astringent, haemostatic, antirheumatic, diuretic. Used for diarrhoea, kidney disorders, bronchitis and for bleeding piles, wounds, bruises. Essential oil— used in bronchial catarrh and cystitis.

The extracts of the plant gave ses- quiterpenes, beta-santalen, beta-hima- chalene, cuparene, alpha-curcumene, gamma-cadinene.

The petroleum ether and ethanolic extracts of aerial parts exhibit significant anti-inflammatory activity.

Aqueous extract of powdered plant produces fall in blood pressure, depresses the heart and increases respiration in animals.

The essential oil, obtained from aerial parts in Japan, is found to contain 47 volatile compounds of which 91.0% are terpenoids. The leaves contain cumu- lene derivatives.

For preparing plant extract as a drug, the volatile oil is removed from a hot aqueous extract and the residue is filtered and concentrated to 24% or 60% of dry matter content. The 6% dry matter extract contains flavones 0.83, tannins 0.52, reducing sugars 6.37 and total sugars 12.6%. The extract is anti- inflammatory, analgesic, bactericidal and fungicidal.... erigeron canadensis

A triazole antifungal drug taken orally for oropharyngeal and vulvovaginal CANDIDA, PITYRIASIS versicolor, and tinea corporis and pedis (see under RINGWORM). It is also used for systemic fungal infections such as ASPERGILLOSIS, candidiasis and cryptococcosis where other fungicidal drugs have not worked. Itraconazole is metabolised in the liver so should not be given to patients who have or have had liver disease. The drug can be given as maintenance treatment of AIDS (see AIDS/HIV) patients to prevent resurgence of underlying fungal disease to which they are vulnerable.

Family: Compositae; Asteraceae.

Habitat: The temperate Himalayas up to 3,600 m and in Khasi Hills between 1,000 and 2,000 m.

English: Hemp Agrimony, Water Hemp, Hemp Eupatorium.

Folk: Bundaar (Maharashtra), Tongollati (Assam).

Action: Diuretic, cathartic, anti-tumoral. Used under strict medical supervision for blood impurities and tumours. Internal administration is not advised unless the hepatotoxic alkaloids are shown to be absent from the sample.

The herb contains volatile oil (about 0.5%); sesqiterpene lactones, the major one being eupatoriopicrin; flavonoids, pyrrolizidine alkaloids; immunoactive polysaccharides.

Eupatoriopicrin has shown to be cy- tostatic as well as cytotoxic; it delayed transplanted tumour growth in mice in a dose-dependent manner.

An aqueous extract of the plant exhibited anti-necrotic activity against carbon tetrachloride-induced hepato- toxicity in rats. The effect is attributed to the presence of flavonoids, rutoside, hyperoside and quercetin; phenolic acids, caffeic and chlorogenic; and not due to the presence of eupatoriopicrin.

Acrylic acid and the lactic, malic and citric acids, present in the plant, also exhibited protective effect against acute toxicity induced by ethanol in mice.

The polysaccharides have immuno- stimulatory activity and enhance phagocytosis in a number of immunolog- ical tests. The leaf oil is reported to exhibit fungicidal effect.

A related species, Eupatorium odorum Linn., is known as Gondri in Ori- ssa.... eupatorium cannabinum

Linn.

Habitat: Cultivated and naturalized throuhout India. Wild in the Sub-Himalayan tract up to 1,800 m.

English: Persian Lilac, Pride of India.

Ayurvedic: Mahaanimba, Ramyaka, Dreka. (Neem is equated with Azadirachta indica.)

Unani: Bakaayan.

Siddha/Tamil: Malaivembu.

Action: Leaf—diuretic, anthelmintic, antilithic. Leaf and flower—febrifuge, sedative, em- menagogue. Leaf, fruit and stem bark—antileprotic. Leaf, flower, fruit, root bark—deobstruent, resolvent. Seed oil—antirheumatic, insecticidal. Leaves, bark and fruit—insect repellent. Gum— used in spleen enlargement. Heart- wood—an aqueous extract, used in asthma.

The Ayurvedic Pharmacopoeia ofIn- dia indicated the use of the dried stem bark in increased frequency and turbidity of urine, skin diseases, nausea, emesis, asthma, gastroenteritis, giddiness and vertigo.

The bitter constituents are present exclusively in the pericarp, not in the kernel as in the case of Neem fruit. Bakayanin has been isolated from the pericarp (bitter in dilutions of 1 in 10,000).

The heartwood also yielded bakaya- nin and a lactone, bakalactone. Leaves gave quercitrin and rutin and tetranor- triterpenoids, salanin and vilasinin.

An infusion of the bark is effective against ascariasis. The activity resides in the inner bark which is bitter but not astringent (outer bark contains tannins and is astringent).

The ethanolic extract of the leaves is fungicidal and antibacterial. The activity is attributed to azadrine and me- liotannic acid.

The fruits are considered poisonous to man and animals; contain melianon- inol, melianol, melianone, meliandi- ol, vanillin and vanillic acid. Vanillic acid analogues show micro- and macro-filaricidal activity.

Gedunin, present in the plant, inhibits Plasmodium falciparum, while the seed extract does not show anti- malarial activity against P. berghei.

The plant exhibited sedative and psychostimulant properties. Antitu- mour and antiviral activities have also been reported. Intraperitoneal administration of partially purified extracts of fresh green leaves reduced the spread of Tacaribe virus (that causes typical encephalitis) to kidneys, liver and brain in inoculated neonatal mice.

Dosage: Stem bark—5-10 g (API, Vol. IV.); leaf, seed, root—50- 100 ml decoction; 3-5 g powder. (CCRAS.)... melia azedarach

Stapf.

Family: Rutaceae.

Habitat: Native to tropical America; cultivated in Indian gardens.

Family: Umbelliferae; Apiaceae.

Habitat: Native to the Mediterranean region; cultivated in Uttar Pradesh., Punjab, Assam and Orissa.

English: Anise, Aniseed.

Unani: Anisoon, Baadiyaan-roomi.

Action: Carminative, diuretic, anticholerin, antispasmodic, expectorant. Used for flatulence, dry coughs, whooping cough, bronchitis.

Key application: Internally in dyspeptic complaints; internally and externally in catarrhs of the respiratory tract. (German Commission E, ESCOP, WHO, The British Herbal Pharmacopoeia.)

The fruit gave volatile oil consisting mainly of trans-anethole (70-90%), with estragole, anise ketone, anisic acid, beta-caryophyllene, anisaldehyde, linalool. The fruit contained traces of furocoumarins; seeds gave benzoic acid, caffeic acid, containing protein and myristicin. Roots afforded sterols, coumarins and flavone glyco- sides. Aniseed has been demonstrated to increase the mucociliary transport in vitro and to significantly increase liver-regeneration in rats.

Aniseed is also used as a galacta- gogue. This property is thought due to the presence of polymers of anethole, dianethole and photoanethole.

Aqueous extract of roasted aniseed is reported to show cholinomimetic effect on rat blood pressure, rat jejunum and frog rectus abdominis preparations.

Alcoholic extract of aniseeds possesses antimicrobial and fungicidal activity.

Anethole has a structure similar to catecholamines including adrenaline, noradrenaline and dopamine and to the hallucinogenic compound myris- ticin as well. (Natural Medicines Comprehensive Database, 2007.)... pilocarpus microphyllus

Ammi majus

Apiaceae

Importance: Greater Ammi, also known as Bishop’s weed or Honey plant is an annual or biennial herb which is extensively used in the treatment of leucoderma (vitiligo) and psoriasis. The compounds responsible for this are reported to be furocoumarins like ammoidin (xanthotoxin), ammidin (imperatorin) and majudin (bergapten) present in the seed. Xanthotoxin is marketed under the trade name “Ox soralen” which is administered orally in doses of 50 mg t.d. or applied externally as 1% liniment followed by exposure of affected areas to sunlight or UV light for 2 hours. It is also used in “Suntan lotion”. Meladinine is a by-product of Ammi majus processing, containing both xanthotoxin and imperatorin sold in various formulations increases pigmentation of normal skin and induces repigmentation in vitiligo. Imperatorin has antitumour activity. Fruit or seed causes photosensitization in fouls and sheep.

Distribution: The plant is indigenous to Egypt and it grows in the Nile Valley, especially in Behira and Fayoom. It is also found in the basin of the Mediterranean Sea, in Syria, Palestine, Abyssinia, West Africa, in some regions of Iran and the mountains of Kohaz (Ramadan, 1982). It grows wild in the wild state in Abbottabad, Mainwali, Mahran and is cultivated in Pakistan. The crop was introduced to India in the Forest Research Institute, Dehra Dun, in 1955 through the courtesy of UNESCO. Since then, the crop has been grown for its medicinal fruit in several places in Uttar Pradesh, Gujarat, Kashmir and Tamil Nadu.

Botany: Ammi majus Linn. belongs to the family Apiaceae (Umbelliferae). A. visnaga is another related species of medicinal importance. A. majus is an annual or beinnial herb growing to a height of 80 to 120 cm. It has a long tap root, solid erect stem, decompound leaves, light green alternate, variously pinnately divided, having lanceolate to oval segments. Inflorescence is axillary and terminal compound umbels with white flowers. The fruits are ribbed, ellipsoid, green to greenish brown when immature, turning reddish brown at maturity and having a characteristic terebinthinate odour becoming strong on crushing with extremely pungent and slightly bitter taste.

Agrotechnology: Ammi is relatively cold loving and it comes up well under subtropical and temperate conditions. It does not prefer heavy rainfall. Though the plant is biennial it behaves as an annual under cultivation in India. A mild cool climate in the early stages of crop growth and a warm dry weather at maturity is ideal. It is cultivated as a winter annual crop in rabi season. A wide variety of soils from sandy loam to clay loam are suitable. However, a well drained loamy soil is the best. Waterlogged soils are not good. Being a hardy crop, it thrives on poor and degraded soils.

The plant is seed propagated. Seeds germinate within 10-12 days of sowing. The best time of sowing is October and the crop duration is 160-170 days in north India. Crop sown later gives lower yield. The crop can be raised either by direct sowing of seed or by raising a nursery and then transplanting the crop. Seed rate is 2 kg/ha. The land is brought to a fine tilth by repeated ploughing and harrowing. Ridges and furrows are then formed at 45-60 cm spacing. Well decomposed FYM at 10-15 t/ha and basal fertilisers are incorporated in the furrows. Seeds being very small are mixed with fine sand or soil, sown in furrows and covered lightly with a thin layer of soil. A fertilizer dose of 80:30:30 kg N, P2O5 and K2O/ha is generally recommended for the crop while 150:40:40 kg/ha is suggested in poor soils for better yields. The furocoumarin content of Ammi majus is increased by N fertiliser and the N use efficiency increases with split application of N at sowing, branching and at flowering. For obtaining high yields it is essential to give one or two hoeings during November to February which keeps down the weeds. If winter rains fail, one irrigation is essential during November to January. As the harvesting season is spread over a long period of time, two irrigations during March and April meets the requirements of the crop (Chadha and Gupta, 1995).

White ants and cut worms are reported to attack the crop which can be controlled by spraying the crop with 40g carbaryl in 10 l of water. Damping off and powdery mildew are the common diseases of the crop. Seed treatment with organomercuric compounds is recommended for damping off. To control powdery mildew the crop is to be sprayed with 30g wettable sulphur in 10 l of water whenever noticed.

The crop flowers in February. Flowering and maturity of seed is spread over a long period of two months. The primary umbels and the early maturing secondary umbels are the major contributors to yield. A little delay in harvesting results in the shattering of the seed which is the main constraint in the commercial cultivation of the crop and the main reason for low yields in India. Sobti et al (1978) have reported increased yield by 50 - 60% by the application of planofix at 5 ppm at flower initiation and fruit formation stages. The optimum time of harvest is the mature green stage of the fruit in view of the reduced losses due to shattering and maximum contents of furocoumarins. The primary umbels mature first within 35-45 days. These are harvested at an interval of 2-4 days. Later, the early appearing secondary umbels are harvested. Afterwards, the entire crop is harvested, stored for a couple of days and then threshed to separate the seeds. The seed yield is 900-1200 kg/ha.

Postharvest technology: The processing of seed involves solvent extraction of powdered seeds, followed by chilling and liquid extraction and chromatographic separation after treatment with alcoholic HCl. Bergapten, xanthotoxin and xanthotoxol can be separated. Xanthotoxol can be methylated and the total xanthotoxin can be purified by charcoal treatment in acetone or alcohol.

Properties and activity: Ammi majus fruit contains amorphous glucoside 1%, tannin 0.45%, oleoresin 4.76%, acrid oil 3.2%, fixed oil 12.92%, proteins 13.83% and cellulose 22.4%. This is one of the richest sources of linear furocoumarins. Ivie (1978) evaluated the furocoumarin chemistry of taxa Ammi majus and reported the presence of xanthotoxin, bergapten, imperatorin, oxypencedanin, heraclenin, sexalin, pabulenol and many other compounds. Furocoumarins have bactericidal, fungicidal, insecticidal, larvicidal, moluscicidal, nematicidal, ovicidal, viricidal and herbicidal activities (Duke, 1988).... greater ammi

Cedrus atlantica

FAMILY: Pinaceae

SYNONYMS: Atlantic cedar, Atlas cedar, African cedar, Moroccan cedarwood (oil), libanol (oil).

GENERAL DESCRIPTION: Pyramid-shaped evergreen tree with a majestic stature, up to 40 metres high. The wood itself is hard and strongly aromatic, due to the high percentage of essential oil which it contains.

DISTRIBUTION: Native to the Atlas mountains of Algeria; the oil is mainly produced in Morocco.

OTHER SPECIES: Believed to have originated from the famous Lebanon cedars (C. libani), which grow wild in Lebanon and on the island of Cyprus. It is also a close botanical relation to the Himalayan deodar cedarwood (C. deodora), which produces a very similar essential oil. (NB the oil is quite different from the Texas or Virginia cedarwood.)

HERBAL/FOLK TRADITION: The oil from the Lebanon cedar was possibly the first to be extracted, it was used by the ancient Egyptians for embalming purposes, cosmetics and perfumery. The oil was one of the ingredients of ‘mithridat’, a renowned poison antidote that was used for centuries. The Lebanon cedar was prized as a building wood; its odour repelled ants, moths and other harmful insects, as does the oil from the Atlas cedar.

Traditionally, the oil was used in the East for bronchial and urinary tract infections, as a preservative and as an incense. It is still used as a temple incense by the Tibetans, and is employed in their traditional medicine.

Commiphora myrrha

FAMILY: Burseraceae

SYNONYMS: Balsamodendron myrrha, gum myrrh, common myrrh, hirabol myrrh, myrrha.

GENERAL DESCRIPTION: The Commiphora species which yield myrrh are shrubs or small trees up to 10 metres high. They have sturdy knotted branches, trifoliate aromatic leaves and small white flowers. The trunk exudes a natural oleoresin, a pale yellow liquid which hardens into reddish-brown tears, known as myrrh. The native collectors make incisions in the bark of the tree to increase the yield.

DISTRIBUTION: The Commiphora species are native to north east Africa and south west Asia, especially the Red Sea region (Somalia, Yemen and Ethiopia).

OTHER SPECIES: There are several C. species which yield myrrh oleoresin: African or Somali myrrh (C. molmol) and Arabian or Yemen myrrh (C. abyssinica). Bisabol myrrh or opopanax (C. erthraea) also belongs to the same family.

HERBAL/FOLK TRADITION: Myrrh has been employed since the earliest times in Eastern and Western medicine; its use is mentioned some 3700 years ago. The ancient Egyptians used it for embalming purposes and in their perfumes and cosmetics. In China it is used for arthritis, menstrual problems, sores and haemorrhoids. In the West it is considered to have an ‘opening, heating, drying nature’ (Joseph Miller), good for asthma, coughs, common cold, catarrh, sore throat, weak gums and teeth, ulcers and sores. It has also been used to treat leprosy.

Current in the British Herbal Pharmacopoeia as a specific for mouth ulcers, gingivitis and pharyngitis.

Allium cepa

FAMILY: Liliaceae

SYNONYMS: Common onion, Strasburg onion.

GENERAL DESCRIPTION: A perennial or biennial herb up to 1.2 metres high with hollow leaves and flowering stem, and a globelike fleshy bulb.

DISTRIBUTION: Native of western Asia and the Middle East, it has a long history of cultivation all over the world, mainly for culinary use. The essential oil is mainly produced in France, Germany and Egypt from the ‘red’ onion.

OTHER SPECIES: There are numerous species of onion which have been developed, which include the Spanish or silver-skinned onion, the Tripoli and the red onion. See also Botanical Classification.

HERBAL/FOLK TRADITION: Onion has an ancient reputation as a curative agent, highly extolled by the schools of Galen and Hippocrates. It is high in vitamins A, Band C and shares many of the properties of garlic, to which it is closely related. Raw onion helps to keep colds and infections at bay, promotes strong bones and a good blood supply to all the tissues. It acts as an effective blood cleanser which, along with the sulphur it contains, helps to keep the skin clear and in good condition. It has a sound reputation for correcting glandular imbalance and weight problems; it also improves lymphatic drainage which is often responsible for oedema and puffiness.

Onion has long been used as a home ‘simple’ for a wide range of conditions: ‘As a poultice they are invaluable for the removal of hard tumours. In this form they afford relief in cases of suppressed gout or obstructed circulation ... Onions tend to soothe the nerves and induce sleep. They stimulate the action of the skin and remove obstructions of the viscera ... raw onions, bruised are good for burns and scalds in the absence of other remedies ... applied to the sting or bite of any poisonous insect often proves all that is desired.’ .

ACTIONS: Anthelmintic, antimicrobial, antirheumatic, antiseptic, antisclerotic, antispasmodic, antiviral, bactericidal, carminative, depurative, digestive, diuretic, expectorant, fungicidal, hypocholesterolaemic, hypoglycaemic, hypotensive, stomachic, tonic, vermifuge.

PRINCIPAL CONSTITUENTS: Mainly dipropyl disulphide, also methylpropyl disulphide, dipropyl trisulphide, methylpropyl trisulphide and allylpropyl disulphide, among others.

SAFETY DATA: Specific safety data unavailable at present – probably similar to garlic, i.e. generally non-toxic, non-irritant, possible sensitization.

AROMATHERAPY/HOME: USE None, due to its offensive smell.

OTHER USES: Used in some pharmaceutical preparations for colds, coughs, etc. The oil is extensively used in most major food categories, especially meats, savouries, salad dressings, as well as alcoholic and soft drinks. It is not used in perfumery work.... onion

DISTRIBUTION: Native to Europe, naturalized in North America. Extensively cultivated, especially in Spain, France, Yugoslavia and the USA for its essential oil.

OTHER SPECIES: Closely related to the thyme family, with which it shares many characteristics. There are several different types ‘of savory’ which include S. thymbra, found in Spain, which contains mainly thymol, and the winter savory (S. montana) – see separate entry.

HERBAL/FOLK TRADITION: A popular culinary herb, with a peppery flavour. It has been used therapeutically mainly as a tea for various ailments including digestive complaints (cramp, nausea, indigestion, intestinal parasites), menstrual disorders and respiratory conditions (asthma, catarrh, sore throat). Applied externally, the fresh leaves bring instant relief from insect bites, bee and wasp stings.

‘This kind is both hotter and drier than the winter kind ... it expels tough phlegm from the chest and lungs, quickens the dull spirits in the lethargy.’.

ACTIONS: Anticatarrhal, antiputrescent, antispasmodic, aphrodisiac, astringent, bactericidal, carminative, cicatrisant, emmenagogue, expectorant, fungicidal, stimulant, vermifuge.

Citrus sinensis

FAMILY: Rutaceae

SYNONYMS: C. aurantium var. dulcis, C. aurantium var. sinensis, China orange, Portugal orange.

GENERAL DESCRIPTION: An evergreen tree, smaller than the bitter variety, less hardy with fewer or no spines. The fruit has a sweet pulp and non-bitter membranes. Another distinguishing feature is the shape of the leaf stalk: the bitter orange is broader and in the shape of a heart.

DISTRIBUTION: Native to China; extensively cultivated especially in America (California and Florida) and round the Mediterranean (France, Spain, Italy). The expressed oil is mainly produced in Israel, Cyprus, Brazil and North America; the distilled oil mainly comes from the Mediterranean and North America.

OTHER SPECIES: There are numerous cultivated varieties of sweet orange, for example Jaffa, Navel and Valencia. There are also many other subspecies such as the Japanese orange (C. aurantium var. natsudaidai). See also bitter orange.

HERBAL/FOLK TRADITION: A very nutritious fruit, containing vitamins A, B and C. In Chinese medicine the dried sweet orange peel is used to treat coughs, colds, anorexia and malignant breast sores. Li Shih-chen says: ‘The fruits of all the different species and varieties of citrus are considered by the Chinese to be cooling. If eaten in excess they are thought to increase the “phlegm”, and this is probably not advantageous to the health. The sweet varieties increase bronchial secretion, and the sour promote expectoration. They all quench thirst, and are stomachic and carminative.’.

ACTIONS: Antidepressant, anti-inflammatory, antiseptic, bactericidal, carminative, choleretic, digestive, fungicidal, hypotensive, sedative (nervous), stimulant (digestive and lymphatic), stomachic, tonic.

EXTRACTION: 1. Essential oil by cold expression (hand or machine) of the fresh ripe or almost ripe outer peel. 2. Essential oil by steam distillation of the fresh ripe or almost ripe outer peel. An oil of inferior quality is also produced by distillation from the essences recovered as a byproduct of orange juice manufacture. Distilled sweet orange oil oxidizes very quickly, and anti-oxidant agents are often added at the place of production. (An oil from the flowers is also produced occasionally called neroli Portugal or neroli petalae; an oil from the leaves is also produced in small quantities.)

SYNONYM: 1. A yellowy-orange or dark orange mobile liquid with a sweet, fresh fruity scent, richer than the distilled oil. It blends well with lavender, neroli, lemon, clary sage, myrrh and spice oils such as nutmeg, cinnamon and clove.

2. A pale yellow or colourless mobile liquid with a sweet, light-fruity scent, but little tenacity.

PRINCIPAL CONSTITUENTS: Over 90 per cent monoterpenes, mainly limonene. The cold expressed oil also contains bergapten, auraptenol and acids.

SAFETY DATA: Generally non-toxic (although ingestion of large amounts of orange peel has been known to be fatal to children); non-irritant and non-sensitizing (although limonene has been found to cause dermatitis in a few individuals). Distilled orange oil is phototoxic: its use on the skin should be avoided if there is danger of exposure to direct sunlight. However, there is no evidence to show that expressed sweet orange oil is phototoxic although it too contains coumarins.

AROMATHERAPY/HOME: USE

Skin care: Dull and oily complexions, mouth ulcers.

Circulation muscles and joints: Obesity, palpitations, water retention.

Respiratory system: Bronchitis, chills.

Digestive system: Constipation, dyspepsia, spasm.

There are also several other similar species, notably the Chinese spikenard (N. chinensis) which is also used to produce an essential oil. Not to be confused with aspic or spike lavender (Lavandula latifolia), nor with essential oils from the musk root (Ferula sumbul) which is collected from the same area. The roots of several other plants are also commonly sold as ‘Indian valerian root’.

HERBAL/FOLK TRADITION: Spikenard is one of the early aromatics used by the ancient Egyptians and is mentioned in the Song of Solomon in the Bible. It is also the herb which Mary used to anoint Jesus before the Last Supper; ‘Then took Mary a pound of ointment of spikenard, very costly, and anointed the feet of Jesus, and wiped his feet with her hair; and the house was filled with the odour of the ointment.’.

The oil was also used by the Roman perfumers, or unguentarii, in the preparation of nardinum, one of their most celebrated scented oils, and by the Mughal empress Nur Jehan in her rejuvenating cosmetic preparations. It was also a herb known to Dioscorides as ‘warming and drying’, good for nausea, flatulent indigestion, menstrual problems, inflammations and conjunctivitis.

ACTIONS: Anti-inflammatory, antipyretic, bactericidal, deodorant, fungicidal, laxative, sedative, tonic.

EXTRACTION: Essential oil by steam distillation from the dried and crushed rhizome and roots.

Tagetes minuta

FAMILY: Asteraceae (Compositae)

SYNONYMS: T. glandulifera, tagette, taget, marigold, Mexican marigold, wrongly called ‘calendula’ (oil).

GENERAL DESCRIPTION: A strongly scented annual herb about 30 cms high with bright orange, daisylike flowers and soft green oval leaves.

DISTRIBUTION: Native to South America and Mexico. Now grows wild in Africa, Europe, Asia and North America. The oil is mainly produced in South Africa, France, Argentina and Egypt, the absolute in Nigeria and France.

OTHER SPECIES: There are several other types of tagetes which share similar characteristics and are used to produce essential oils, notably the French marigold (T. patula) and the African or Aztec marigold (T. erecta) – see also Botanical Classification section.

NB: Not to be confused with the ‘true’ marigold (Calendula officinalis) which has very different properties and constituents, and is used extensively in herbal medicine (and occasionally to make an absolute). See entry on marigold.

HERBAL/FOLK TRADITION: In India the locally grown flowering tops of the French marigold are distilled into a receiver which contains a solvent, often sandalwood oil, to produce ‘attar genda’ – a popular Indian perfume material. In China the flowers of the African marigold are used for whooping cough, colds, colic, mumps, sore eyes and mastitis – usually as a decoction.

ACTIONS: Anthelmintic, antispasmodic, bactericidal, carminative, diaphoretic, emmenagogue, fungicidal, stomachic.

EXTRACTION: 1. An essential oil by steam distillation from the fresh flowering herb. 2. An absolute (and concrete) by solvent extraction from the fresh flowering herb.

CHARACTERISTICS: 1. A dark orange or yellow mobile liquid which slowly solidifies on exposure to air and light, with a bitter-green, herby odour. 2. An orange, olive or brown semi-liquid mass with an intense, sweet, greenfruity odour. It blends well with clary sage, lavender, jasmine, bergamot and other citrus oils in very small percentages.

PRINCIPAL CONSTITUENTS: Mainly tagetones, with ocimene, myrcene, linalol, limonene, pinenes, carvone, citral, camphene, valeric acid and salicylaldehyde, among others.

SAFETY DATA: ‘It is quite possible that “tagetone” (the main constituent) is harmful to the human organism.’. Some reported cases of dermatitis with the tagetes species. Use with care, in moderation.

AROMATHERAPY/HOME: USE

Skin care: Bunions, calluses, corns, fungal infections.

OTHER USES: Used in some pharmaceutical products. The absolute and oil are employed to a limited extent in herbaceous and floral perfumes. Used for flavouring tobacco and in most major food categories, including alcoholic and soft drinks.... tagetes

Melaleuca alternifolia

FAMILY: Myrtaceae

SYNONYMS: Narrow-leaved paperbark tea tree, ti-tree, ti-trol, melasol.

GENERAL DESCRIPTION: A small tree or shrub (smallest of the tea tree family), with needle-like leaves similar to cypress, with heads of sessile yellow or purplish flowers.

DISTRIBUTION: Native to Australia. Other varieties have been cultivated elsewhere, but M. alternifolia is not produced outside Australia, mainly in New South Wales.

OTHER SPECIES: Tea tree is a general name for members of the Melaleuca family which exists in many physiological forms including cajeput (M. cajeputi) and niaouli (M. viridiflora), and many others such as M. bracteata and M. linariifolia – see Botanical Classification section.

HERBAL/FOLK TRADITION: The name derives from its local usage as a type of herbal tea, prepared from the leaves. Our present knowledge of the properties and uses of tea tree is based on a very long history of use by the aboriginal people of Australia. It has been extensively researched recently by scientific methods with the following results: ‘1. This oil is unusual in that it is active against all three varieties of infectious organisms: bacteria, fungi and viruses. 2. It is a very powerful immuno-stimulant, so when the body is threatened by any of these organisms ti-tree increases its ability to respond.’ .

ACTIONS: Anti-infectious, anti-inflammatory, antiseptic, antiviral, bactericidal, balsamic, cicatrisant, diaphoretic, expectorant, fungicidal, immuno-stimulant, parasiticide, vulnerary.

EXTRACTION: Essential oil by steam or water distillation from the leaves and twigs.

CHARACTERISTICS: A pale yellowy-green or water-white mobile liquid with a warm, fresh, spicy-camphoraceous odour. It blends well with lavandin, lavender, clary sage, rosemary, oakmoss, pine, cananga, geranium, marjoram, and spice oils, especially clove and nutmeg.

PRINCIPAL CONSTITUENTS: Terpinene-4-ol (up to 30 per cent), cineol, pinene, terpinenes, cymene, sesquiterpenes, sesquiterpene alcohols, among others.

SAFETY DATA: Non-toxic, non-irritant, possible sensitization in some individuals.

AROMATHERAPY/HOME: USE

Skin care: Abscess, acne, athlete’s foot, blisters, burns, cold sores, dandruff, herpes, insect bites, oily skin, rashes (nappy rash), spots, verrucae, warts, wounds (infected).

Respiratory system: Asthma, bronchitis, catarrh, coughs, sinusitis, tuberculosis, whooping cough.

Genito-urinary system: Thrush, vaginitis, cystitis, pruritis.

Immune system: Colds, fever, ’flu, infectious illnesses such as chickenpox.

OTHER USES: Employed in soaps, toothpastes, deodorants, disinfectants, gargles, germicides and, increasingly, in aftershaves and spicy colognes.... tea tree

Thymus vulgaris

FAMILY: Lamiaceae (Labiatae)

SYNONYMS: T. aestivus, T. ilerdensis, T. webbianus, T. valentianus, French thyme, garden thyme, red thyme (oil), white thyme (oil).

GENERAL DESCRIPTION: A perennial evergreen subshrub up to 45 cms high with a woody root and much-branched upright stem. It has small, grey-green, oval, aromatic leaves and pale purple or white flowers.

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.
