The use of natural antioxidants in supplements can also exhibit pro-oxidant activity under certain conditions such as the concentration and nature of the polyphenolic compounds causing oxidative damage to important cellular components (48). Aqueous extracts and erode polyphenolic fractions of both traditional and green rooibos were evaluated for possible pro-oxidant activity using a Fenton reaction model system containing FeCb-EDTA and H2O2 for the generation of hydroxyl radicals. Pro-oxidant activity was shown for pure aspalathin while the dihydrochalcone and flavonoid contents of the enriched... 

Only recently the first human intervention study was completed in the Western Cape Province of South Africa to monitor the modulation of oxidative stress by traditional rooibos in adults at risk for developing heart disease (hhp //sarooibos.co.za/content/view). This study also served as the first scientific proof for human safety when considering the various clinical pathology results (Table IV). 

All packaged finished herbal teas exhibited low values of moisture (<10%), while Lippia was higher at moisture contents ranging from 11 to 12% (Table I). Rooibos and Honeybush were characterized by low levels of fine particles (less than 0.3%), while all the other herbal teas contained higher values (>1%), and the Kinkeliba teas processed during 2005 and 2006 with the highest levels (8%).
