Hibiscus cardio-protective actions is no doubt linked to its strong antioxidant activities. This includes inhibition of α-glucosidase and α-amylase, inhibition of angiotensin-converting enzymes (ACE), and a direct vaso-relaxant effect or calcium channel modulation which helps explain its hypotensive action. (3)

Hibiscus extracts have a dual action in the cardiovascular system with the ability to scavenge reactive oxygen species and free radicals, due to its ability to increase the activity of superoxide dismutase. There is compelling evidence that hibiscus extracts decrease the risk factors associated with cardiovascular disease and metabolic syndrome. This may be the result of hibiscus’s effect on lipid metabolism and hypertension. Several animal studies have shown that leaf and flower extracts have the ability to lower blood pressure and plasma levels of low-density lipoproteins, triglycerides, and total cholesterol. In addition, studies in rats and in humans have found an increase in plasma levels of high-density lipoproteins after oral administration of hibiscus extract. The effects of hibiscus on blood lipids and hypertension seem to be more effective at higher doses over longer periods of time. (1)

Hibiscus extracts have also shown protective properties for both liver and kidney tissue in animal and human models which makes it a perfect complementary therapy for metabolic syndrome. In one study in rats, oral administration of hibiscus extracts resulted in an increase in oxalate excretion in the urine and decrease in calcium oxalate crystal formation within the kidneys, potentially decreasing the formation of kidney stones.

Due to its acidic nature and the iron content contained in its flowers Hibiscus can be used as an addition to iron therapy for iron deficiency anaemia.

Hibiscus is best made as a tea as the phenolic acids and poly-saccharides are well extracted in water.
