Green tea, specifically Camellia sinensis, has been used as a medicine for thousands of years. It is originally from China but is mainly used in Asia. This drink has a variety of uses, such as lowering blood pressure to stop cancer. Green tea has more health benefits than black tea. Black tea is developed in such a way that fermentation is possible, while the development of green tea rejects the fermentation process. As a result, green tea contains the highest amount of polyphenols and antioxidants, the substances that give green tea its many health benefits.
