Hibiscus tea is a bit of an acquired taste (sort of like sour cranberries), but if you are trying to keep your caffeine levels in check, it's an equally healthy and caffeine-free alternative to green tea (which seems to have a much better PR agent...)
Egyptian pharaohs sipped hibiscus tea to cool off during a long day watching the slaves build pyramids. Ol' Pharaoh probably also drank hibiscus tea to improve his digestion, and he may have been aware that it increases both urination and bowel movements.
The Egyptian kings did not know about these other healthy benefits of that odd red flower, but you should:
The hibiscus flower has long been rumored to lower blood pressure, but researchers at Tufts University in Boston finally proved it. They learned that, because of its anti-inflammatory properties, hibiscus tea can reduce blood pressure by up to 10 points. For this drastic improvement to occur, you need to consume three cups every day for a few weeks. Also, hibiscus tea has diuretic properties that increase urination, simultaneously lowering blood pressure.
Hibiscus tea also has impressive antioxidant properties, and studies in animals suggest that hibiscus tea can lower LDL cholesterol and guard against its damaging effects. More recent studies indicate that it helps to lower levels of “bad” LDL cholesterol from the body, thereby helping to protect against heart disease and protecting blood vessels from damage.
Research out of India has shown that a phytochemical from the leaves of Sthalpadma, a sub-genus of hibiscus commonly called Confederate rose, restored insulin sensitivity of cells and thereby helped in lowering blood sugar levels in diabetic rats.

So it's not too off-base to suggest that drinking hibiscus tea could increase your lifespan by maintaining good overall health in many organ systems.
It fights cancer, too! Hibiscus tea contains hibiscus protocatechuic acid which has anti-tumor and antioxidant properties. A study conducted by the Department and Institute of Biochemistry at the Chung Shan Medical and Dental College, in Taichung, Taiwan suggests that hibiscus slows down the growth of cancerous cells by inducing apoptosis, commonly known as programmed cell death.
