High in Antioxidants
Study conducted on rats revealed hibiscus extract increased the number of antioxidant enzymes and reduced the harmful effects of free radicals.
Another study on rats had similar findings, showing that parts of the hibiscus plant, such as the leaves, possess potent antioxidant properties.
May Lower Blood Pressure
Hibiscus tea had shown a decrease in systolic blood pressure during a study on people. Five other studies discovered that hibiscus tea decreased both systolic and diastolic blood pressure.
Hibiscus may be seen as a safe and natural way to help lower blood pressure, though it is not recommended for those taking hydrochlorothiazide, a type of diuretic used to treat high blood pressure, as it may interact with the drug.
