Health Benefits of Hibiscus Tea:
Although few scientific studies have tested the health benefits of hibiscus, early research suggests that hibiscus tea or hibiscus extract may offer antioxidant effects and enhance cardiovascular health. Here’s a look at key findings from the available research on the health benefits of hibiscus:
1) High Blood Pressure
Drinking hibiscus tea daily may benefit people with slightly elevated blood pressure, according to a small study published in The Journal of Nutrition in 2010. For six weeks, 65 adults who had mildly elevated blood pressure (but were not taking blood pressure medication) drank either three cups of hibiscus tea or a placebo beverage each day. Study results revealed that members of the hibiscus group experienced a greater drop in blood pressure (compared to those who consumed the placebo beverage).
In a 2010 research review fromPhytomedicine, scientists sized up four clinical trials on the use of hibiscus tea in treatment of high blood pressure. While each trial showed that hibiscus may help lower blood pressure, the review’s authors caution that three of the four studies were of poor quality.

Hibiscus tea may offer some health benefits to people with type 2 diabetes. In a 2009 study from the Journal of Alternative and Complementary Medicine, for instance, researchers assigned 60 diabetes patients to drink hibiscus tea or black tea twice daily for a month. Looking at data on the 53 people who completed the study, the study’s authors found that members of the hibiscus group had a significant increase in HDL (“good”) cholesterol and a significant decrease in total cholesterol and LDL (“bad”) cholesterol.
In a 2009 study from the Journal of Human Hypertension, meanwhile, scientists discovered that daily consumption of hibiscus tea may help lower blood pressure in people with type 2 diabetes.

3) High Cholesterol
Preliminary findings from animal-based research and test-tube studies indicate that hibiscus extract may help keep cholesterol in check and in turn protect against atherosclerosis.

Using Hibiscus Tea for Health:
It’s too soon to recommend hibiscus as a standard treatment of any health condition. However, since hibiscus contains a number of healthful substances (including anthocyanins), sipping hibiscus tea regularly may offer some mild health benefits.
