Preliminary study has shown that drinking hibiscus tea may lower blood pressure in people with type 2 diabetes, prehypertension, or mild hypertension. However, there is no reliable evidence to support recommending hibiscus tea in the treatment of primary hypertension.

Drinking 3 cups of hibiscus tea daily for 6 weeks reduced systolic blood pressure by 7 mm Hg in prehypertensive and mildly hypertensive participants. In those with mean systolic blood pressure over 129 mm Hg, the reduction was nearly 14 mm Hg. Hibiscus flowers contain anthocyanins, which are believed to be active
