NEW ORLEANS — Drinking hibiscus tea has the potential to lower blood pressure, according to a report presented at the American Heart Association’s annual conference.
Specifically, nutrition scientist Diane McKay found drinking the tea lowered blood pressure in a group of pre-hypertensive and mildly hypertensive adults. Ms. McKay tested 65 volunteers and found over the course of six weeks those in the group who drink three cups of hibiscus tea daily showed a 7.2 point drop in systolic blood pressure compared to a 1.3 point drop in the placebo group.
Volunteers with the highest systolic blood pressure at the start of the study were found to have the greatest response to drinking the tea.
