Regular drinking of green tea can preventing cancer, reducing fat and losing weight, and reducing nicotine damage to smokers.

The effective components of green tea extract are tea polyphenols,which also known as antioxidant and vitamin polyphenols. Tea polyphenols are a class of polyhydroxy compounds contained in tea, referred to as TP. The main chemical components are catechins (flavanols), flavonoids and flavonols, anthocyanins, phenolic acids and phenolic acids, polymeric phenols and other compounds. Catechins are the main components of tea polyphenols, accounting for 65% ~ 80% of the total amount of tea polyphenols. Catechins mainly include catechin (EC), epigallocatechin (EGC), catechin gallate (ECG) and epigallocatechin gallate (EGCG).

Tea polyphenols have strong antioxidant effect. Catechin monomer EGCG is its main antioxidant component, and its reducibility is even 100 times that of l-isoascorbic acid.

Secondly, it has antidote effect on heavy metal salt and alkaloid poisoning. Tea polyphenols have strong adsorption on heavy metals and can form complexes with heavy metals to produce precipitation, which is conducive to reducing the toxic effect of heavy metals on human body.

Thirdly, it has the effect of preventing radiation injury and reducing the adverse reactions of radiotherapy. Tea polyphenols and their oxidation products have excellent anti radiation function, so they can absorb radioactive substances and prevent their diffusion in human body.

Also, it owns the function of preventing caries and removing halitosis. Tea polyphenols can kill lactic acid bacteria and other dental caries bacteria in the tooth gap, inhibiting the activity of glucose polymerase and effectively interrupting the formation of dental caries.
