Polyphenols which are produced by plants are very important functional foods in our nutrition. Because of their diverse chemical structures, they are subject to main classification among them. The main groups of polyphenols are; flavanoids, lignans, stilbenes and phenolic acids. At the present time, the health effects of them have been investigated in several in vivo and in vitro studies. In addition to their antioxidant effects, they are known to have a pro-oxidant character. Polyphenols have important effects in protecting the body against external factors and the cleansing of reactive oxygen species which occur as a consequence of some diseases. Furthermore, polyphenols have effects on protection from specific diseases and stop their progression with certain mechanisms. In this review, various effects of polyphenols including antioxidant, pro-oxidant, cytotoxic, anti-inflammatory, antihypertensive, anti-diabetic are discussed which obtained from in vitro, in vivo experimental animal and clinical investigations.

The concept of hormesis includes a biphasic cellular dose-response to a xenobiotic stimulus defined by low dose beneficial and high dose inhibitory or toxic effects. In the present study, an attempt has been made to help elucidate the beneficial and detrimental effects of thymol on different cell types by evaluating and comparing the impact of various thymol doses on cancerous (AGS) and healthy (WS-1) cells. Cytotoxic, genotoxic, and apoptotic effects, as well as levels of reactive oxygen species and glutathione were studied in both cell lines exposed to thymol (0-600 mu M) for 24 h. The results showed significant differences in cell viability of AGS compared to WS-1 cells exposed to thymol. The differences observed were statistically significant at all doses applied (P <= 0.001) and revealed hormetic thymol effects on WS-1 cells, whereas toxic effects on AGS cells were detectable at all thymol concentrations. Thymol at low concentrations provides antioxidative protection to WS-1 cells in vitro while already inducing toxic effects in AGS cells. In that sense, the findings of the present study suggest that thymol exerts a dose-dependent hormetic impact on different cell types, thereby providing crucial information for future in vivo studies investigating the therapeutic potential of thymol.
