green tea
Green tea is a type of tea that is made from Camellia sinensis leaves and that have not undergone the withering and oxidation process. Several varieties of green tea exist, which differ substantially based on the variety of C. sinensis used, growing conditions, horticultural methods, production processing, and time of harvest. Although there has been considerable research on the possible health effects of consuming green tea regularly, there are few evidences that drinking green tea has effects on health.
