Green Tea and Antioxidant Power
Green tea is made from the leaves and buds of the Camellia sinensis plant that have not undergone the withering and oxidation processes used to make black or oolong teas. Originating in China around the late 1st millennium BC, it has since become popular across East Asia and worldwide. Different varieties of green tea exist depending on plant type, growing region, cultivation methods, processing techniques, and harvest time.
