Green tea has been used as a medicine for thousands of years, originating in China but widely used throughout Asia this beverage has a multitude of uses from lowering blood pressure to preventing cancer.

These are some of the many benefits but the reality is one cup of tea a day will not give you all the abundant gains. The jury is out on how many cups are necessary; some say as little as two cups a day while others five cups — and more still say you can drink up to ten cups a day.
Green tea also contains tannins (which can decrease the absorption of iron and folic acid), so if you are pregnant or trying to conceive then green tea may not be ideal for you. You can try mixing green tea with other healthy ingredients such as ginger.
