Additional Benefits of Hibiscus Extract
Polyphenols are plant compounds recognized for their disease prevention, antioxidant and anti-aging properties, and hibiscus extract is a potent source. Research has shown that hibiscus extract has been used "commonly and effectively… in native medicines" against high blood pressure, diabetes, and liver disorders.3 To date, the variety of studies showing health benefits of hibiscus extract are impressive and include:
Potential anti-cancer effects: Research has shown that polyphenol-rich extracts of hibiscus induced cell death in human gastric carcinoma cells.4 Hibiscus extract has also induced cell death in human leukemia cells.5
Antioxidant benefits: Research revealed that consumption of hibiscus extract enhanced systemic antioxidant potential and reduced oxidative stress in study participants.6 The study also found a "high biotransformation" of the ingested HSE polyphenols, which suggests the compounds are in a highly bioavailable form.
Kidney stones and liver protection: One study found that hibiscus extract has anti-urolithiatic activity, which means it may help reduce the formation of kidney stones.7 It's also been shown to help protect the liver against chemically induced damage in fish.8
Diabetes: Hibiscus extract has shown promise for improving both blood pressure9 and blood lipid profiles in people with diabetes.10
Metabolic syndrome: Hibiscus extract has even shown promise for preventing and treating metabolic syndrome, with one study finding a daily dose of hibiscus extract for just one month lead to improvements in glucose, cholesterol and triglyceride levels as well as improvements in insulin resistance in people with metabolic syndrome.11
