Unani Chaai, Shaahi, Shaayi. Siddha/Tamil Thaeyilai.
Action
b 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, Cam ellia 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 theobromine); 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 bioavailabiity.
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 carcinogenesis in small intestines when given during or after carcinogen treatment to experimental rats. (—)-epigallocatechin gallate and theaflavin digallate from green tea inhibited the infectivity ofboth 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 hypocholesterolaemic activity.
Tea polyphenols—(—)-epicatechin gallate, (—) -epigallo cate chine galate, theaflavin monogallate A or B, and or theaflavin digallate—are used for treating hyperglycaemia.
Saponins from tea are used as antiulcer agents.
