Health Benefits of Rooibos Print
The antioxidants in Rooibos are known to help reduce the risk of strokes and heart attacks. Researchers have now discovered that it could also help prevent skin cancer. The implications are particularly relevant in South Africa where skin cancer is the most common form of cancer with 20,000 reported cases and 700 deaths annually.
 

Early and effective treatment can arrest or cure skin cancer, but poor compliance and the expense associated with many current treatments lead to failure. Other options are thus being investigated, such as plant polyphenols [type of chemical].

Polyphenols have been reported to have antioxidant, antimicrobial, antiviral, antimutagenic, anticarcinogenic, anti-inflammatory, antiproliferative and vosadilatory actions. They may prevent or retard cancer growth.

Recent studies

South African researchers from the Medical Research Council's PROMEC Unit and the Oxidative Stress Research Centre at the Cape Peninsula University of Technology presented the results of two recent studies at the third annual Rooibos Science Caf? in November 2010.

Professor Jeanine Marnewick and her team from the Cape Peninsula University of Technology studied the effect of herbal tea extracts on UV-induced skin tumours in mice. They found that green or unfermented Rooibos reduced the number of tumours per mouse by 75% and fermented Rooibos by 91%. Green Rooibos shrunk the size of the tumours by 91% and fermented Rooibos by 97%. They concluded that polyphenol-rich extracts from Rooibos have anti-tumour and photoprotective properties. This indicates potential for use in cosmeceuticals for sun protection and as part of a strategy for preventing non-melanoma skin cancers in humans.

The MRC study aimed to find out more about how herbal teas affect factors influencing the survival of cancer cells, an essential step in the road to creating an effective anti-cancer product. Rooibos promoted cell death in UV exposed cells, which could play a role in cancer prevention. The researchers concluded that Rooibos may prevent skin cancer by delaying the progression of abnormal cells, interfering with their growth and viability.

The SA Rooibos Council invests some R1 million a year on research. It supports research projects at local universities and science councils. It is hoped that Rooibos can counter cancer, oxidative stress and obesity.
