Did You Know?: Black Tea for High Blood Pressure

It’s well known, or at least widely believed, that green tea is good for you. But did you know that black tea may pack a healthful punch, too?
According to a recent study, drinking black tea can lower blood pressure by an average of two or three points -- enough to lower the risk for high blood pressure by up to 10 percent.
Researchers at the University of Western Australia examined the effects of drinking black tea on 95 men and women with normal to high-normal blood pressure. About half drank three cups of black tea per day for six months. The other half drank a tea-flavored placebo. Compared to the placebo drinkers, those who drank black tea experienced a drop in blood pressure.
What’s so special about black tea? The researchers suspect that it improves the functioning of endothelial cells lining blood vessels that help blood flow smoothly through the body’s circulatory system.
