EGCG is a kind of component extracted from Chinese green tea. It is the primary active and water-soluble component of green tea, which has the highest content among the tea catechins. By virtue of its peculiar stereochemical structure, EGCG possesses much stronger anti-oxidant activities and plays an important role in preventing cancer and cardiovascular diseases. In addition, it is potent as the reversal agent of MDR (Multidrug Resistance). As such, it may improve the sensitivity of cancer cells to chemotherapy drugs and reduce toxicity on the heart.
