Epigallocatechin gallate (EGCG) is the most effective antioxidant polyphenol in green tea, with antioxidant, anti-cancer, anti-mutation and other activities. Antioxidants are at least 100 times as many times as vitamin C and 25 times vitamin E to protect cells and DNA, which are believed to be associated with cancer, heart disease and other major diseases. The effects of EGCG are attributed to their ability to scavenge oxygen free radicals.
