Rooibos shows cardiovascular benefits
The first-ever human clinical trial on the effects of rooibos tea on the cardiovascular system was carried out in South Africa. The research, conducted by a group of scientists from the Cape Peninsula University of Technology, shows that short-term consumption of rooibos tea is safe for the liver and kidneys while keeping various blood parameters in a normal range. Provisional results from the study indicate that "red bush" tea protects the body against oxidative damage, as seen by the 21 percent decrease in conjugated dienes in the blood.
