Hibiscus is a member of the Malvaceae family, or the mallow family of flowering plants. There are more than 200 species, all of which are known for their colorful, showy blooms. There are many folk remedies attributed to hibiscus flowers, including help with stomach or digestive problems, and to help soothe the nerves. Recently it has been added to many ready-made teas due to its high levels of anti-oxidants. The Journal of Human Hypertension published an article that showed that drinking hibiscus tea can reduce the blood pressure in people with type 2 diabetes. (5)

African folk medicine uses hibiscus as a diuretic, to relieve pressure in the gallbladder, and to relax the uterus. The mucilage in the herb make it a mild laxative, but they are also helpful when the herb is used as a wash to treat weeping eczema. Regular consumption of hibiscus teas often lowers blood pressure, typically 8 to 12 mm/Hg. Hibiscus is also the source of the hydroxycitric acid (HCA, or hydroxycut) used in many diet formulas. This compound has been long used to fight obesity. Scientific studies with lab animals find that it stops the conversion of carbs in food to body fat. It fights appetite and encourages weight loss not by increasing energy expenditure but by encouraging the "wasting" of carbohydrates. HCA does not enhance weight loss during low-carb or Atkins-style diets, but it does help weight loss when used with a program of general calorie restriction reducing consumption of carbs, protein, and fats equally. Hibiscus powder will have more of a laxative effect than other forms of the herb. It delivers more HCA. It is also more likely to help lower LDL cholesterol, although definitive research of the use of this herb for controlling high cholesterol has not been completed. Hibiscus is Good for Controlling Pitta Diseases. (3)
