Hibiscus tea may cut blood pressure

"If you're worried about your blood pressure, you may want to follow the British custom of regularly 'sipping a cuppa' - tea, that is. In a new study, drinking three cups of herbal tea containing hibiscus each day lowered blood pressure. 'Most of the commercial herbal tea blends in the United States contain hibiscus,' says Diane L. McKay, PhD, of Tufts University in Boston. She tells WebMD that people with the highest blood pressure at the start of the six-week study benefited the most. McKay presented the study of 65 healthy men and women with modestly elevated blood pressure at the American Heart Association meeting" - WebMD
