What is the difference between green tea and black tea?

Green teas and black teas both come from the same plant – Camellia Sinensis. Hence, they have the same amount of antioxidants and minerals in them. Their only difference is their treatment after they were harvested. Black tea undergoes an oxidation process which results in a flavour and colour change, whereas green tea is not oxidized. Oxidation does not compromise the health benefits of black teas though.
