Green tea is a type of tea that is made from Camellia sinensis leaves and buds that have not undergone the same withering and oxidation process used to make oolong teas and black teas. Green tea originated in China, and since then its production and manufacture have spread to other countries in East Asia.

• Several varieties of green tea exist, which differ substantially based on the variety of C. Sinensis used in growing conditions, horticultural methods, production processing, and time of harvest.
