Green tea is a type of tea that is made from Camellia sinensis leaves that have not undergone the same withering and oxidation process used to make oolong teas and black teas.

Some of the extracts of Green tea inhibit the activity of the Murine leukemia virus[1].

Green tea contains epigallocatechin gallate (EGCG) which is a strong antioxidant.

Theory[edit | edit source]

Regular green tea is 99.9% water, provides 1 Calorie per 100 ml serving, is devoid of significant nutrient content (table) and contains phytochemicals, such as polyphenols and caffeine. Polyphenols found in green tea include epigallocatechin gallate (EGCG), epicatechin gallate, epicatechins and flavanols,[citation needed] which have antioxidant, anticarcinogen, anti-inflammatory, and anti-radiation biochemical effects in vitro. Other components include three kinds of flavonoids, known as kaempferol, quercetin, and myricetin.

Evidence[edit | edit source]
