Honeybush activity

Rooibos and Honeybush Recent Advances in Chemistry, Biological Activity and Pharmacognosy... 

Japanese and South African researchers were the first to scientifically investigate the possible health promoting properties of rooibos which led to publications reporting on various biological activities (31-37). A few studies regarding the in vitro, in vivo and ex vivo biological activities of honeybush has been published by mainly South African researchers and are mostly limited to the exported species, Cyclopia intermedia. These studies will be discussed. 

When comparing the antioxidant potencies of both the traditional/fermented and green/unfermented rooibos and honeybush, evidence is difficult to select for the best one, since the activity is highly dependent on the assay used, the nature of the raw material, and type of samples (aqueous extracts, enriched-extracts or solvent extracts) used.
