Hibiscus is a plant. The flowers and other parts of the plant are used to make medicine.
People use hibiscus for high blood pressure, high cholesterol, to increase the production of breast milk, and many other conditions, but there is no good scientific evidence to support most of these uses.
How does it work?
The fruit acids in hibiscus may work like a laxative. Some researchers think that other chemicals in hibiscus might be able to lower blood pressure; reduce levels of sugar and fats in the blood; decrease spasms in the stomach, intestines, and uterus; reduce swelling; and work like antibiotics to kill bacteria and worms.
