Green tea originates from China and India, and it is prepared from the leaves of the Chinese Camellia sinensis. Tea is the most consumed drink in the world after water, except that the most popular type is red, not green, and this tea is prepared from the not oxidized leaves, and therefore it contains the highest percentage of antioxidants, and it should be noted that the types of tea differ according to the level of oxidation of the leaves.
