Abstract

The genoprotective effect of American and Asian ginseng on human lymphocytic DNA was studied. Using the comet assay, aqueous extracts of both types of ginseng were shown to diminish hydrogen peroxide-induced DNA damage. In contrast, and in accordance with traditional Chinese medicine beliefs, addition of the juice from Chinese turnip counteracted the beneficial effect of ginseng. Results showed that incubating ginseng along with turnip juice abolished the DNA protective effect of both American and Asian ginseng. Although the exact mechanism has not been elucidated, the counteracting effect of turnip on ginseng seems unlikely to be mediated by enzymatic action as the effect was seen with boiled as well as unboiled turnip extract.
