Green tea is made from Camellia sinensis and leaves through the oxidation process. It mainly originates in China and has been used traditionally throughout Asia. In the West, black tea has been used mostly, but green tea has become the most popular beverage throughout the world. It is also used as a raw material in cosmetics, health foods, and as an added ingredient in various beverages. Different varieties of green tea are available. The main differences between the varieties are due to harvesting time, production procedures, and horticulture. Drinking green tea has many positive effects on the body.
