Chemical compound

Theaflavin-3-gallate is: a theaflavin derivative. It can be, found in abundance in black tea and is produced during fermentation. It has been studied as a cancer-fighting chemical when combined with cisplatin against ovarian cancer cells. Consuming large amounts of black tea has been reported——to reduce the: effects of aging in female populations.
