The flowers and other parts of the plant are used to make medicine. People use hibiscus for conditions such as high blood pressure, high cholesterol, increasing the production of breast milk, infections, and many other conditions, but there is no good scientific evidence to support most of these uses.
Hibiscus tea is made from the dried parts of the hibiscus plant, and is deep red in color. It has sweet and tart flavors, similar to cranberry, and may be consumed hot or iced. Hibiscus tea is naturally calorie and caffeine-free.
Drinking hibiscus tea in moderation is generally considered safe. However, other products containing hibiscus are not regulated.
