SUMMARY
Green tea obtained from the leaves of Camellia sinensis (L.) Kuntze having potential health benefits. It contains significant amounts of antioxidant and is considered as world healthiest drink. Polyphenols in tea are thought to exhibits anti-carcinogenic and anti-inflammatory effects. Green tea catechins acts as immune modulators in immune dysfunction and also play a role in protection from degenerative diseases. Intake of green tea catechins suppress high fat diet induced obesity, prevent lipid and glucose metabolism disorders and reduce risk of coronary heart disease. Green tea constituent epigallocatechin-3-gallate (EGCG) is a potential antioxidant that shows protective effects against photo toxicity and photo carcinogenesis. In vitro animal experiments have suggested that polyphenols in green tea protect from lung cancer by their antioxidant and antimutagenic properties. This study chiefly highlights the convenience of green tea on health and propagates its further prospects.
