  • Title: Medicinal plants and antioxidants: what do we learn from cell culture and Caenorhabditis elegans studies?
    Author: Tang SY, Halliwell B.
    Journal: Biochem Biophys Res Commun; 2010 Mar 26; 394(1):1-5. PubMed ID: 20188074.
    Abstract:
    Traditional medicinal plants have a long history of therapeutic use. The beneficial health effects of medicinal plants rich in polyphenols are often attributed to their potent antioxidant activities, as established in vitro, since diets rich in polyphenols are epidemiologically associated with a decreased incidence of age-related diseases in humans. However, medicinal plants may also exert pro-oxidant effects that up-regulate endogenous protective enzymes. Care is needed when studying the biological effects of medicinal plants in cell culture because some polyphenols oxidize readily in culture media. This review summarizes the data we have obtained from in vitro and in vivo (Caenorhabditis elegans) studies examining the diverse effects of traditional medicinal plants and their modes of action.
