Clinical Trial Shows Cardiovascular Benefits for Rooibos, Popular Antioxidant Herbal Tea from South Africa
Austin, TX. September 10, 2008. The first-ever human clinical trial on a popular traditional South African herbal tea was recently conducted, testing whether the tea can possibly lower the risk of cardiovascular disease.
The new trial also generated the first human safety data in a controlled clinical trial environment, scientifically showing that short-term consumption of rooibos tea is safe for the liver and kidneys while keeping various blood parameters (e.g., blood pressure, cholesterol levels, etc.) in a normal range.1
Provisional results from this study indicate that rooibos tea protects the body against oxidative damage, as seen by the approximate 21% decrease in conjugated dienes in the blood. Conjugated dienes are products formed in large numbers during the early stages of oxidation (destruction) of important cellular components such as fats (lipids). These lipid peroxidation products may be implicated in the development of vascular disease.
