Protection, Vascular Disorders Trial Clinical Study Results: To evaluate

the anti-caries effect of green tea, a group of 150 volunteers were

randomly divided into 3 groups: A, B and C with 50 persons in each.

People in test groups A and B were given a green tea polyphenol tablet

whereas placebo was given to group C (tablets were taken three times

daily). After 3 weeks, group A was given placebo and group B continued

with polyphenols for 6 weeks. After using polyphenol tablets for 2

weeks, the plaque index of test groups were clearly lower than the

control group (P < 0.01). After stopping use of the polyphenol

tablet, the effect was still kept for 3 weeks. It can be concluded that

polyphenol tablets from Chinese green tea have significant anti-plaque

effect and can therefore help to prevent dental cavities. Active

Constituents: Green and black tea leaves contain: methylxanthines -

caffeine (theine), up to 4% with smaller amounts of theobromine and

theophylline, as well as traces of adenine and xanthine; tannins.

Polyphenols: tannins, mainly catechol tannins (10-20%); (-)-epicatechol,

4-gallocatechol, epigallocatechin gallate (EGCG) and other catechol

gallates; flavan-3-ols and flavan-3.4-diols, as well as dimeric thea-

flavins and oligomeric proanthocyanidins (thearubigenins); phenolic

carboxylic acids such as gallic and chlorogenic acids, etc. Flavour

substances: alcohols (hex-3-en-1-ol, benzyl alcohol, and 2-phenyl-

ethanol, as well as linalool in black tea and geraniol in green tea.);

essential oils (monoterpene aldehydes and alcohols); and theanine, the

5-ethylamide of glutamic acid. Other constituents: abundant flavonoids

(including the apigenin derivatives isoschaftoside and vicenin-3);

triterpenoid saponins; hydroperoxide lyases (anti-oxidant enzymes, and

potent inhibitors of lipoxygenase). The accumulation of aluminum in tea

leaves and the occasionally high content of fluorine compounds in older

leaves are worth noting. Recent studies show that the residual green tea

leaves remaining after tea is made are also rich in powerful

antioxidants including (ranked according to suppressive activity against

hydroperoxide generation): chlorophyll a > lutein > pheophytin a

> chlorophyll b > beta-carotene > pheophytin b. [Wichtl and
