Burdock

Arctium lappa. N.O. Compositae.

Synonym: Hill, Lappa, Thorny Burr.

Habitat; This large plant, which grows to a height of five feet, is very commonly met along roadsides and in all waste places—indeed, wherever we see nettles, there also will be found Burdock.

Features ? Stout stems with wide spreading branches carrying alternately fleshy, heart-shaped leaves. The purple flowers bloom luxuriously in July and August, and the bristly burs or bracts adhere lightly to the clothes and coats of animals. The root is thick, brownish-grey externally, whitish inside. Roots and seeds have a sweetish, slimy taste, the leaves and stems being bitter.

Part used ? Root, seeds and the herb itself are used.

Action: Possesses alterative, diuretic and diaphoretic qualities, the root and herb

being predominantly alterative, while the seeds affect more specifically the kidneys.

The liquid from 1 ounce of the root boiled in 1^ pints of water simmered down to 1 pint, is taken four times daily in wineglass doses for many forms of skin trouble, noticeably boils, carbuncles and similar eruptions. Obstinate cases of eczema and even psoriasis have been known to yield to these decoctions of Burdock root, either alone or combined with other remedies.

An excellent lotion may be made by infusing the leaves in the proportion of 1 ounce to 1 pint of water.... burdock

Hin: Kebu, Keyu, Kust;

Ben: Keu, Kura

Mal: Channakkizhangu, Channakoova;

Tam: Kostam; Mar: Penva;

Tel: Kashmeeramu

Importance: Costus is one of the plants which contains diosgenin in its rhizome. It is widely used as starting material in the commercial production of steroidal hormones. The rhizomes are useful in vitiated conditions of kapha and pitta, burning sensation, flatulence, constipation, helminthiases, leprosy, skin diseases, fever, hiccough, asthma, bronchitis, inflammation and aneamia. It is used to make sexual hormones and contraceptives (Warrier et al,1994).

Distribution: The plant is widely distributed in Asia and other tropical countries like India, Nepal, Pakistan, Sri Lanka and China. In India, it occurs mostly in Arunachal Pradesh, Meghalaya, Nagaland, Tamil Nadu, Assam, Tripura and Kerala.

Botany: Costus speciosus (Koenig.) Sm. belonging to the family Zingiberaceae consists of two varieties viz., var. nepalensis Rose., found only in Nepal and Arunachal Pradesh and var. argycophyllus Wall., having a wide distribution in India.

The plant is a succulent herb with long leafy spirally twisted stems, 2-3m in height and horizontal rhizomes. Leaves are simple, spirally arranged, oblanceolate or oblong, glabrous above, silky pubescent beneath with broad leaf sheaths. Flowers are white, large, fragrant, arranged in dense terminal spikes. Bracts are bright red. The single stamen present is perfect, lip large with incurved margins. Fruits are globose or ovoid capsules with obovoid or sub- globose seeds (Warrier et al,1994).

Agrotechnology: Costus can be raised under a wide range of agroclimatic conditions. It prefers sandy loam soil for good growth. Propagation is by rhizomes. The best season for planting is April- May. The seed rate recommended is 2-2.4t/ha. The spacing adopted is 50x50cm. After an initial ploughing FYM or poultry manure should be applied at the rate of 30t/ha and the field is to be ploughed again irrigated and prepared to obtain a fine seed bed. Furrows are opened and the rhizome pieces are placed horizontally at a depth of 8-10cm and covered with soil. Care is taken to place the eye buds facing upwards. After 70-75 days about 90-95% sprouting is obtained. Desiccation of the young sprouts have been observed in the hot summer months, necessitating liberal water supply during the period. As September-November is the period of maximum tuberization at least two irrigations should be given at that time. One during the sprouting period of the crop followed by two more keeps the crop fairly free of weeds. Application of 37t/ha of poultry manure and fertilizers, 60kg P2O5 and 40kg K2O /ha as a basal doze, along with 80kg N/ha applied in 3 equal split dozes will take care. Crop is harvested at the end of seven months. Harvesting includes 2 operations, cutting the aerial shoots and digging out the rhizomes. Cost of production of diosgenin ranges from Rs. 271-300/kg (Atal, et al,1982).

Properties and activity: Tubers and roots contain diosgenin, 5 -stigmast-9(11)-en-3 ol, sitosterol- -D- glucoside, dioscin, prosapogenins A and B of dioscin, gracillin and quinones. Various saponins, many new aliphatic esters and acids are reported from its rhizomes, seeds and roots. Seeds, in addition, contain - tocopherol. Saponins from seeds are hypotensive and spasmolytic. Rhizomes possess antifertility, anticholinestrase, antiinflammatory, stimulant, depurative and anthelmintic activities (Hussain et al, 1992).... costus

Curcuma

Zingiberaceae

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

1. C. amada Roxb.

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

Mal: Mangainchi

Tam: Mankayinci

Tel: Mamidi Allam

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

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

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

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

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

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

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

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

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

Tel: Kacheramu

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

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

Other important species of Curcuma genus are

C. angustifolia Roxb. (Vellakoova)

C. caesia Roxb. (Black ginger)

C. leucorhiza Roxb.

C. pseudomontana Grah.

C. rubescens Roxb.

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

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

Importance: Holostemma is a twining shrub with large flowers. The roots of Holostemma are useful in ophthalmopathy, orchitis, cough, burning sensation, stomachalgia, constipation, fever and tridoshas. The leaves, flowers and fruits are eaten as vegetable. The root is also used in spermatorrhoea. It is used in preparations of Vidaryadiganam, Dhanwandharam thaila, Manasamithravatakam, Balarishta and Anuthaila. It is also useful in eye diseases and it imparts resistance to diseases.

Distribution: The plant occurs in tropical countries. In India, it is found in Himalayas, Dehradun, Konkan, Bombay, Deccan, Karnataka, Kerala and Tamilnadu. It grows over hedges and in open forests especially on the lower slopes of the hills. It is also distributed in Sri Lanka, Burma and W. China.

Botany: Holostemma ada-kodien Schult. syn. Holostemma annulare (Roxb.) K. Schum.

Holostemma rheedii Wall. belongs to the family Asclepiadaceae. It is a laticiferous twining shrub with large conspicuous flowers. Leaves are simple, opposite and cordate. Flowers are purple, arranged in axillary umbellate cymes. Fruits are thick follicles, 9 cm long, cylindrical and bluntly pointed. The roots are long upto 1 m or more, irregularly twisted, thick and cylindrical. When dry it is yellowish brown to brown black in colour with nearly smooth surface bearing white scars and small depressions. A mature root is about 1-2 cm thick when extracted for use (Warrier et al, 1995).

Agrotechnology: Holostemma prefers a tropical climate. The plant is propagated vegetatively by stem cuttings, but mainly by seeds. The seeds are collected from the plant in November-December before being dispersed. Seeds are cleaned, dried and stored for sowing. The stored seeds after soaking in water for 4-5 hours are sown in the seedbeds. About one month old seedlings are then planted in polybags of size 14x10cm which are filled with soil, sand and dried cowdung in 1:1:1 ratio, respectively. Polybags should be kept in shade and irrigated. About 1-1.5 month old seedlings are ready for transplanting. Pits of 30cm cube size are taken at 1-1.2m distance and filled with 10kg dried cowdung and sand. This is covered with surface soil and formed into a mound. Seedlings are transplanted on to the mounds from the polybags carefully. Regular irrigation is to be given till flowering. To aid in trailing, staking is given one month after planting. Flowering and fruiting occurs in November-December. Harvesting can be done at the end of second year when the vines start drying up. Harvesting is done by digging up the tubers. The tubers are cut into pieces of 10cm length and dried in sun before sale (Prasad et al, 1997).

Properties and activity: Holostemma tubers give -amyrin, lupeol and -sitosterol. Alanine, aspartic acid, glycine, serine, threonine and valine were detected chromatographically (Hussain et al, 1992). The root is antidiabetic, antigonorrhoeic, bechic, alterative, tonic, lactative, ophthalmic, emollient, stimulant, aphrodisiac, expectorant and galactagogue.

It has been recorded to occur in the sub tropical Himalayas from Kumaon eastwards ascending to 1800m, the Khasia hills, Bengal, Asssam, Konkan, Kanara, the western peninsula and Madras extending south as far as a Cape Comerin. It is also distributed in Sri Lanka, Japan, Malaysia and Australia.

Botany: Curculigo orchioides Gaertn. syn. C. malabarica Wight, C. brevifolia Dryand, Hypoxis dulcis Stand belongs to the family Amaryllidaceae. Musali is a small herbaceous plant with cylindrical rootstock. Leaves are simple, sessile, crowded on the short stem with sheathing leaf bases. Flowers are bright yellow. Seeds are black, deeply grooved in wavy lines.

A detailed description of the plant is as follows (Victoria, 1998). Rootstock is straight, cylindrical, tuberous, 5-22cm long, 0.5-0.8 cm thick, brownish surfaces marked with closely spaced prominent transverse wrinkles in the upper or basal half. It bears a few stout lateral roots of 5 or more cm long. Lateral roots are dull white in colour and spongy externally. The fresh cut surfaces of the rootstock has a starch white colour and mucilaginous. A few fibrous roots also occur. Leaves are sessile or short petiolate with sheathing bases, 15-45x1.2-2.5 cm size, linear or linear lanceolate, membranous, glabrouus or sparsely sofly hairy and plicate in bud. The leaf tips when contacts the soil, develops roots and produce adventitious buds. Inflorescence is axillary, scapose racemose, the scape very short and hidden among the bases of leaves underground, clavte, flattened with the pedicels, bracts and the ovary concealed in the leaf sheaths. The lower big flowers on the scape are mostly bisexual and the upper small ones staminate. Flowers are epigynous bright yellow, bisexual or unisxual with lanceolate, memb ranous bract.. Perianth gamophyllous, rotate & six lobed, locate at the top of a slender sterile long extension of the ovary by means of which the perianth is exposed above the ground. Perianth lobes similar, elliptic oblong 1.2-1.6 cm long, 0.2-0.3 cm broad, outer lobes hairy on the back, inner ones sparsely hairy along nerves. Stamens 6 in number, filamentous filiform, short 2mm long, adnate to the base of the perianth lobes, Anthers linear or linear lanceolate, basifixed and sagittate,.Ovary inferior, hidden among the leaves usually below the ground, tricarpellary syncarpous, lanceolate and trilocular with a fairly long slender beak or extension -the stipe. Ovules many in each cell attached by a distinct long funicle. Style short columnar, 2mm with a 3 lobed stigma. Lobes elongate, erect and appressed. Fruit is a capsule about 1.5-2cm long, 8mm broad, oblong, glabrescent with a slender beak and spongy septa. Seeds 1-many, oblong, black, shiny with crustaceous testa grooved deeply in wavy lines.

Properties and activity: Rao and Beri (1951) have identified glucose, mannose, xylose and glucuronic acid from the rootstock of C. orchioides. The rootstock is also reported to contain glycoside, polysaccharides (hemicellulose and other polysaccharides), starch, resin, tannin, mucilage, fat and calcium oxalate. The hexane extract contains an alkaloid-lycorine, sterols including -sitosterols and sapogenin identified as yuccagenin (Rao et al, 1978). The flavone glycoside from the rootstock has been identified as 5,7- dimethoxy glucopyranoside (Yadav et al, 1974; Sharma et al 1975). Mehta et al (1980) have isolated a number of fatty acids from C. orchioides root oil by GLC techniques. They are palmitic, oleic, linolenic linoleic, arachidic and behenic acid. Kubo et al (1983) isolated a new phenolic glycoside namely, curculigoside from the rhizomes and its structure has been elucidated as 5- hydroxy-2-0- -d-glucopyranosyl benzl 1,2,6-dimethoxy benzoate. Yamasaki et al (1994) developed HPLC method for estimating the curculigoside content in curculigo rhizome.

Two new aliphatic hydroxy ketone 27-hydroxy tricontan-6-one (M. P. 84-85o C) and 23- hydroxy tricontan-2-one (M. P. 109-110 o C) were isolated from the rhizome by Misra et al (1984). They also isolated 21-hydroxy tetracontan-20-one and 4-methyl heptade canoic acid from the root stock. Porwal et al (1988) have isolated and identified three new compounds from the rhizome as N- acetyl-N-hydroxy-2-carbamic acid methyl ester, 3-acetyl-5-carbomethoxy-2H-3,4,5,6-tetrahydro-1,2,3,5,6-oxatetrazine and N, N, N’, N’-tetra methyl succinamide. The rhizomes of C. orchioides yielded a new phenolic glycoside corchioside a, characterised as orcinol-3- -D-xylopyranosyl- (1 6)- -D-glucopyranoside and hentriacontanol (Garg et al, 1989).

A new aliphatic compound has been isolated from the rhizomes and characterised as 25- dihydroxy-33-methyl pentatricontan-one (Mehta et al, 1990). Misra et al (1990) isolated a new natural triterpene alcohol-Curculigol charactrised as 24-methy cycloart-7-en-3-beta-20-diol. A novel pentacyclic triterpene has been isolated from the rhizomes of C.orchioides and characterised as 31- methyl-3-oxo-20-ursen-28-oic acid (Metha and Gawarikar,1991). Xu and Xu (1992) and Xu et al (1992 a, b) have isolated 13 cycloartane type. Triterpene glycosides from C. orchioides rhizome and characterised them as curculigo saponin A-M.

The root stock are mucilaginous, sweet, cooling, bitter, emollient, diuretic, aphrodisiac, depurative, alternative, appetiser, carminative, viriligenic, antipyretic and tonic (Sivarajan and Indira, 1994; Warrier et al, 1994).

The uterine stimulant activity of the flavone glycoside extracted from C. orchioides has been studied by Dhawan and Saxena (1958), Sharma et al (1975) and Dhar et al (1979).

The plant extract of C. orchioides showed hypoglycaemic, spasmolytic and anticancer properties (Dhar et al,1968). Phagocytic activity (Kubo et al, 1983) and immunoadjuvant activity (Oru et al, 1982) of phenolic glycosides, curculigoside isolated from the rhizome of the plant have been reported. Porwal and Mehta (1985) discussed the medicinal importance of the plant and its use in indigenous system of medicine as a tonic. Sharma et al (1991) reported the influence of MAK an ayurvedic food supplement constituting C. orchioides against Dimethyl benz anthracene induced mammary tumours in rats. Samanta (1992) reported the modulation of male infertility by Ayurvedic drug, which constitutes C. orchioides. Immunostimulant activity of C. orchioides has been demonstrated by Saxena (1992). Immunological activites of curculigo saponin G were assayed in mice and the results showed that it promoted proliferation of spleen lymphocyctes very significantly and increased the weight of the thymus in vivo in mice (Xu et al,1992).

Pharmacological studies in China, on the alcoholic extract obtained from the plant showed several active effects such as adaptogenic, anti-inflammatory, anticonvulsant, sedative, androgenic and immunopromoting activities (Xu et al, 1992).

Curculigo orchioides is distributed widely throughout the country. The demand of the raw materials and derivatives of the plant for the indigenous drug industries are satisfied mainly from the wild source, depleting the natural population and thus the species have become extinct or endangered. Ansari (1993) have reported C. orchioides as a threatened plant from Madhulia forest of Garakhpur. Augustin and Souza (1995) also considered the plant as an endangered species. As the information on the cultivation of C.orchioides is scanty, it is very necessary to develop suitable agrotechniques for the domestication and large-scale cultivation of the plant.... holostemma

Malabar Nut

Adhatoda beddomei

Acanthaceae

San:Vasaka, Vasa;

Hin:Adusa; Mal:Chittadalotakam;

Tam:Adutota; Tel:Addasaramu

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

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

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

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

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

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

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

Tam: Itti, Kagodi, Kanjirai Mar:Jharkhatchura;

Kan: Hemmushti, Ittangi;

Tel: Mushti, Mushidi; Ori: Kora, Kachila

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Grindelia

Grindelia squarrosa

FAMILY: Asteraceae

SYNONYMS: Gumweed, hardy grindelia, gum plant, scaly grindelia, rosin weed, curlytop gumweed, curlycup gumweed, tarweed, resin-weed, sticky-heads.

GENERAL DESCRIPTION: A biennial or short-lived perennial up to one metre high with yellow, daisy-like flower heads, each with overlapping rows of backward-curling, bracts: squarrosa is Latin for ‘scaly or rough’, referring to these curling bracts. The leaves are dotted with resinous glands: thus many common names for Grindelia squarrosa, such as gumweed, refer to the gooey resin that they exude, which has a sweet incense-like scent. This white viscous gum may cover the entire bud top and flowers, which bloom in late summer from July to September. However, the dried flowering heads may persist for several years due to the preservative action of the gummy resin!

DISTRIBUTION: This plant is native to western North America and Mexico. It is naturalized in eastern North America and the Pacific Coast states: several species are also cultivated as ornamentals in Europe.

OTHER SPECIES: Grindelia comprises about 60 species: the name of the genus honours the Russian botanist, David Grindel. All are native to North and Central America and chiefly distributed in warm-temperate regions. Several species are used to produce essential oils, including G. oregana and G. robusta as well as G. squarrosa. All these oils were found to contain alpha-pinene, ?-pinene, limonene, borneol, bornyl acetate trans-pinocarveol and germacrene D as the main constituents and only showed small differences in chemical composition. However, menthol, menthone and pulegone were detected only in the essential oil of G. oregano.

HERBAL/FOLK TRADITION: Grindelia has been used as a traditional herbal remedy by indigenous cultures all over the Americas for centuries. The plant was harvested when in full bloom and used fresh as a poultice or herbal extract or dried for infusions etc. The herb was used by Great Plains Tribes mainly to treat respiratory problems, such as asthma, colic, coughs and bronchitis, especially among the aged; the leaves were smoked to relieve spasmodic asthma. Externally, the crushed flowers were used to make poultices, which was applied to burns, rashes, poison ivy, blisters, dermatitis, eczema, saddle sores and raw skin. The leaves and flowering tops was used to make an herbal tea used to relieve coughs and dizziness. The sticky sap was chewed as gum and herbal extracts were also used to treat rheumatic conditions. Spanish New Mexicans would also drink a tea made from boiling the flower buds in water, for treating kidney problems. The Eclectic School of Medicine used Grindelia externally to promote skin regrowth and to heal reluctant, persistent ulcers.

The medicinal value of this plant was not recognized by the orthodox practitioners of medicine in the US till the middle of the nineteenth century, after which it came into prominence as a major medicinal plant. Official recognition of Grindelia came with the introduction of the herb in the Pharmacopoeia of the United States in 1882. It is still listed in the U.S. Dispensatory, and is currently used by modern Americans in the treatment of colds, hay fever, nasal congestion, whooping cough, bronchial catarrh, asthma etc. It is current in the German Commission E for catarrh of the upper respiratory tract and the British Pharmacopoeia also lists the antispasmodic, expectorant and cardiac depressant properties of this herb. The positive effects of this herb on the relief of symptoms of common cold have been recognized empirically. Indeed recent studies have shown it to have good expectorant and antispasmodic as well as moderate anti-inflammatory and antibiotic effects. It also appears to aid allergenic attacks, not only by relieving the symptoms but in creating anti-bodies to reduce episodes and their severity. Secondary uses include the treatment of cystitis and fever, usually in combinations with other herbs. It is also indicated externally in lotion form for the treatment of eczema, dermatitis and rashes due to poison ivy, hives etc.

ACTIONS: Anti-asthmatic, antibacterial, antidepressant, antihistamine, anti-inflammatory, antimicrobial, antiseptic, antispasmodic, astringent, cooling, decongestant, emetic, expectorant, immune support, mucolytic, regenerative, sedative.

EXTRACTION: The essential oil is steam distilled from the flowering plant.

CHARACTERISTICS: A mobile liquid with a strong, earthy-herbaceous, medicinal and slightly camphoraceous odour. It blends well with eucalyptus, ravintsara, myrtle, pine, cypress and peru balsam.

PRINCIPAL CONSTITUENTS: Alpha-pinene (aprox. 25 per cent) is the major constituent, with ?-pinene, limonene, borneol, bornyl acetate and germacrene D. Data is lacking regarding the interaction of the chemistry of the aromatic resin and the volatile oils.

SAFETY DATA: No adverse effects have been reported in the literature regarding the safety of Grindelia in the case of therapeutic application. However, data is lacking regarding the essential oil specifically.

AROMATHERAPY/HOME: USE

Skin Care: Acne, blisters, cuts, eczema, dermatitis, rashes (hives etc), stretch marks, scars, ulcers, wounds and skin care generally.

Respiratory System: Aids breathing, asthma, catarrh, chronic colds, bronchitis, congestion, hay fever, fever, ’flu, sinusitis, sore throat, whooping cough.

Immune System: Supports the immune system.

Nervous System: Nervous tension, stress.

OTHER USES: A homeopathic remedy is prepared from the leaves and flowering stems. It is used by pharmaceutical companies in whooping cough and asthma drugs; also available as a tincture.... grindelia
