Hundreds of millions of people drink tea in the world, and studies suggest that green tea (Camellia Sinesis) in particular has many health benefits. Green tea originated from China and has associated with many cultures in Asia, Japan to the Middle East. It has recently been more widespread in the West, where traditionally black tea is consumed.
There are three varieties of tea – green, black, and oolong. The difference between the teas is in their processing. Green tea is made exclusively from leaves of “Camellia sinensis”, which have undergone minimal oxidation during processing done.
Green tea contains salubrious polyphenols, especially the catechin, epigallocatechin gallate is the most common. Green tea also contains tocopherols, carotenoids, ascorbic acid (vitamin C), minerals such as manganese, chromium, selenium and zinc, and certain phytochemicals. It is an effective antioxidant than black tea.
