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

Bacopa monnieri

Scrophulariaceae

San: Brahmi, Sarasvati;

Hin: Barami, Jalnim;

Ben: Boihim-sak;

Mal: Brahmi , Nirbrahmi;

Tam: Nirpirami, Piramiyapundu; Kan, Mar: Nirbrahmi

Importance: Brahmi or Thyme leaved gratiola is an important drug in Ayurveda for the improvement of intelligence and memory and revitalisation of sense organs. It clears voice and improves digestion. It is suggested against dermatosis, anaemia, diabetes, cough, dropsy, fever, arthritis, anorexia, dyspepsia, emaciation, and insanity. It dispels poisonous affections, splenic disorders and impurity of blood. It is useful in vitiated conditions of kapha and vata, biliousness, neuralgia, ascites, flatulence, leprosy, leucoderma, syphilis, sterility and general debility. The whole plant is used in a variety of preparations like Brahmighrtam, Sarasvataristam., Brahmitailam, Misrakasneham, etc. In unani Majun Brahmi is considered as a brain tonic.

Distribution: The plant grows wild on damp places and marshy lands in the major part of the plains of India, Pakistan, Afghanistan, Nepal, Sri Lanka and other tropical countries.

Botany: Bacopa monnieri (Linn.) Pennell. syn. Monniera cuneifolia Michx., Herpestis monniera (Linn.) H.B. & K. belongs to the family Scrophulariaceae. It is a prostrate, juicy, succulent, glabrous annual herb rooting at the nodes with numerous ascending branches. Leaves are simple, opposite, decussate, sessile, obovate-oblong or spatulate, entire, fleshy, obscurely veined and punctate. Flowers are pale blue or whitish, axillary, solitary, arranged on long slender pedicels. Fruits are ovoid, acute, 2-celled, 2-valved capsules and tipped with style base. Seeds are minute and numerous (Warrier et al, 1993).

Agrotechnology: The plant grows throughout the warm humid tropics upto 1200m elevation. Brahmi gets established well in water logged fields. The plant is propagated vegetatively by stem cuttings. Land is prepared by ploughing 2 or 3 times. Two to three tonnes/ha of cowdung or compost is applied and the field is again ploughed and levelled. Stem cuttings, 10cm long are spread at a spacing of 20cm. Waterlogging to height of 30cm is always required. Rooting may start within 15-20 days. It will spread over the field within 6 months. Regular application of organic manure will take care of the manurial requirement. Weeding once in a month is required. Care should be taken to maintain water level at a height of 30cm during the growth period. No serious pests or diseases are noted in this crop. Harvesting commences from sixth months onwards. Brahmi leaves can be collected once a month. After 3 years, the whole crop is harvested and removed. Fresh cultivation can be carried out in the same field.

Properties and activity: Earlier workers have reported the isolation of the alkaloids brahmine and hespestine and a mixture of 3 alkaloids from the leaves. Mannitol and saponins were reported later. Subsequent work described isolation of some C27, C29, and C31 hydrocarbons and betulic acid from this plant material. A systematic examination has resulted in the isolation and identification of two saponins designated as bacosides A and B. Bacoside A has chemical structure represented as 3-(-L-arabinopyranosyl)-O- - D-glucopyranoside-10, 20-dihydroxy-16-ketodammar-24-ene. The mixture of bacosides A and B on hydrolysis give four sapogenins, glucose and arabinose. The constitution of bacogenin A, has been established as 3 -30-dihydroxy-20(5)-25-epoxy-22-methyl-24-nor-dammar-22-en-16-one. Bacogenin A2 has been shown to be an isomer of bacogenin A, differing in configuration at C-20. Bacogenin A4 has been identified as ebelin lactone.

The plant is reported to have shown barbiturate hypnosis potentiation effect. The plant is anticancerous and improves learning ability. It is used as a tranquilliser. The plant is astringent, bitter, sweet, cooling, laxative, intellect promoting, anodyne, carminative, digestive, antiinflammatory, anticonvulsant, depurative, cardiotonic, bronchodialator, diuretic, emmenagogue, sudorfic, febrifuge and tonic (Basu et al, 1947; Rastogi et al 1960).... brahmi
