Hibiscus Sabdariffa goes by many names: hibiscus, roselle, Jamaica sorrel, Queensland jelly plant, sour-sour and Florida cranberry. Whatever it's called, it packs a healthy punch.
Widely cultivated in the tropics, hibiscus's exact origins are unclear. It was adopted in the new world when it was brought over by African slaves.
Hibiscus's role in cardiovascular health is an exciting area of research. Scientists have confirmed that constituents exhibit potent antioxidant activity and exert beneficial effects on blood pressure and cholesterol. Hibiscus appears to lower blood pressure in part because of its diuretic effect and by inhibiting angiotensin-converting enzyme (ACE), a compound that increases blood pressure.
