Habitat: Western temperate Himalayas from 2,500 to 4,000 m.
English: American cowslip, Marsh Marigold, Water Buttercup.Folk: Mamiri (Punjab).Family: Theaceae.Habitat: Cultivated in Assam, Darjeeling, Travancore, the Nilgiris, Malabar, Bengal, Dehra Dun and Kumaon.
English: Tea.Unani: Chaai, Shaahi, Shaayi.Siddha/Tamil: Thaeyilai.Action: Stimulant, diuretic, astringent. In China, used for diarrhoea and dysentery (causes gastrointestinal upsets and nervous irritability when consumed in excess). Green tea: anticancer effects have been observed in Chinese green tea, Camellia thea, extract; the extract of Japanese green tea showed antihepatotoxic effects.
Important constituents of leaf buds and very young leaves are: caffeine, with a much smaller amount of other xanthines (theophylline and theo- bromine); tannins (the main tannin in green tea is (-)-epigallocatechin); flavonoids, quercetin, kaempferol. The stimulant and diuretic are due to caffeine content, the astringency due to the tannins.Drinking tea lowers thiamine and thiamine diphosphate losses in urine and blood serum respectively but increases niacin losses. Hot water extract of black tea facilitates Ca absorption in the body experimentally. Tea may decrease zinc bioavailability.The tea, if added to the meal, significantly lower the availability of iron. Milk is as effective as ascorbic acid in countering the depressing effect of tea on iron availability (in vitro).The green tea catechin inhibited car- cinogenesis in small intestines when given during or after carcinogen treatment to experimental rats. (-)-epi- gallocatechin gallate and theaflavin di- gallate from green tea inhibited the in- fectivity of both influenza A and B virus (in vitro).Green tea, when added to a lard- cholesterol diet, decreased the cholesterol and triglyceride levels in fowls. Tea polyphenols exhibit hypocholes- terolaemic activity.Tea polyphenols—(-)-epicatechin gallate, (-)-epigallocatechine galate, theaflavin monogallate A or B, and or theaflavin digallate—are used for treating hyperglycaemia.Saponins from tea are used as an- tiulcer agents.Concurrent use of tea and beta- adrenergic agonists may increase the risk of cardiac arrhythmias. Caffeine, a component of tea, may increase insulin resistance. (Sharon M. Herr.)... camellia sinensisHabitat: Native of China; grown in gardens throughout India.
English: Rose-of-China, Shoe- flower, Chinese Hibiscus.Ayurvedic: Japaa, Javaa, Odrapush- pa, Rudrapushpa, Arunaa.Unani: Gul-e-Gurhal.Siddha/Tamil: Semparuthi.Action: Flower—used in impo- tency, bronchial catarrh. Flower and bark—emmenagogue. Leaf— stimulates expulsion of placenta after childbirth; laxative, anodyne. Flower and root—used in menorrhagia.
The plant contains the cyclopro- panoids, methyl sterculate, methyl- 2-hydroxysterculate, 2-hydroxystercu- late, malvalate and beta-sitosterol.The major anthocyanin in the flower is cyanidin 3-sophoroside. The flower nectar is rich in amino acids, mainly aspartic acid and asparagin. During pollination, the amino acid concentration increases substantially.Flower powder exhibited anti-inflammatory activity in male albino rats with carrageenan-induced rat paw oedema. The aqueous extract of the plant showed antitumour activity against sarcoma 180 ascites.An aqueous extract of flowers reduced the duration of oestrus cycle in experimental albino rabbits. The alcoholic extract of flowers showed antiimplantation activity. The benzene extract of flowers, on oral administration, terminated pregnancy in experimental animals.Flower buds are used in the treatment of vaginal and uterine discharges.Oral administration of flower extract to rats affected spermatogenesis and endocrine function of testis.In diabetic patients, a flower bud is given daily up to 10 days or until the level of blood sugar is reduced to tolerable limits.The white-flowered var. of Japan (cultivated all over India in garden) is equated with Hibiscus syriacus Linn. (Rose of Sharon, Shrubby Althaea). The white flower is an oriental drug used as demulcent and antidiarrhoeal. The bud yields mucilage which consists mainly of partially acetylated acidic polysaccharides. The aqueous extract of the petals causes vasorelaxation of the isolated rat arota via both endo- thelium-dependent and -independent mechanisms. The petals contain anthocyanin pigments.The cortex and bark exhibit antifun- gal acitivity.The bark gave canthin-6-one and a fatty acid fraction consisting of lauric, myristic and palmitic acids.Dosage: Flower—10-20 g paste.
