The tannins in green tea have a very obvious effect on lowering blood pressure, not only inhibiting the increase in blood pressure, but also reducing high blood pressure. Studies have also pointed out that tannins can eliminate excess cholesterol in the blood, can control the evolution of arteriosclerosis to a minimum, and help prevent cerebral thrombosis and myocardial infarction.
