Green tea is known for numerous health benefits which has been studied scientifically. Polyphenols, especially epigallocatechin gallate (EGCG), in green tea are potent antioxidants as it limits the amount of free radicals by binding to reactive oxygen species. It also protects the skin from premature aging, and repair damage caused by the ultraviolet rays through faster cell regeneration and rejuvenation. Green tea extract, when applied externally, can relieve redness caused by the sun due to its anti-inflammatory properties. Anti-inflammatory effects may be a result of increased production of IL-10, an anti-inflammatory cytokine. Green tea is also known for its anti-carcinogenic effects which are seen in many types of cancer.
EGCG inhibits angiogenesis and cell growth, and induces apoptosis in cancer cells. It also inhibits the adhesion of cancer cells to endothelial cell layers. Thus green tea has anti-carcinogenic & anti-metastatic effects. Green tea is also known for its antimicrobial effect on the bacteria causing dental caries. In addition, green tea is a natural source of fluoride which strengthens the teeth. Thus, modern scientific techniques have given the basis for the health-promoting effects of green tea, which have been recognized from ancient times.
