Green tea is made from the leaves of Camellia sinensis, an evergreen shrub native to Southeast Asia. Both green tea and black tea are made from the same plant species. Green tea is produced by lightly steaming the leaves. Black tea is produced by allowing the leaves to ferment.
Green tea is rich in the class of polyphenol compounds known as catechins. Polyphenols may have health benefits for humans. Many of the effects of green tea are thought to be due to its most abundant catechin, epigallocatechin gallate (EGCG).
Green tea also contains caffeine. One cup of tea contains approximately 50 milligrams of caffeine, while coffee typically contains 65-175 milligrams of caffeine per cup.
Traditional health claims for green tea include improved urine flow, relief of joint pain, and improved resistance to diseases. Historically, green tea bags have been applied to the body to soothe sunburn, headache, and tired eyes. Green tea is an accepted cancer prevention treatment in Japan and Fiji.
