About Green Tea
This is something that has been gaining popularity over the years. Though born in China, green tea has had all kinds of incarnations in different parts of the world. Made exclusively with the leaves of Camellia sinensis (haril chai), green tea is quite popular in the west. Science turned its focus on this recently and found that it is highly beneficial for health without having any side effects. And this accounts for people switching from the warmth of regular black to green tea.
How does it vary from black tea?
Tea in general is made from the leaves of Camellia sinensis. Predominantly, there are three types of tea -black, green and oolong depending on the way tea leaves are processed. And there is the not-so popular white tea too. Green tea is the least processed of all and thus retains the antioxidant, catechin polyphenols called epigallocatechin-3-gallate (EGCG) along with caffeine. This is the main ingredient responsible for the health benefits. Remember, nature cures!
How are the leaves processed?
The freshly harvested tea leaves are steamed to a soft pliable stage so that they do not lose their natural colour or aroma. Then they are rolled, spread out and dried.The black and oolong tea leaves are made from fermented leaves which make them incapable of retaining any beneficial stuff inside.
