Just 3 cups of hibiscus tea a day could reduce blood pressure, a study has shown.
Sixty-five people aged between 30 and 70 with "at risk" blood pressure levels were split into two groups. The first group drank hibiscus tea three times a day. The second group drank hibiscus-flavored water.
After six weeks, the hibiscus group showed an average fall of 7.2 % in blood pressure. Some even recorded a 13.2 % drop. The placebo group recorded a 1.3 % drop.
All-natural hibiscus tea contains antioxidants, which have been linked to many health benefits, including protection against heart disease and cancer.
Nutrition scientist Diane McKay, PhD, of Tufts University in Boston, presented the study to the American Heart Association's annual conference.
