Ginseng root is reputed to lower blood sugar and cholesterol levels, protect against stress, enhance strength and promote relaxation. Koreans have fed ginseng to race horses to enhance their performance on the track. Although some European and Asian studies appear to support some of these claims, American researchers remain skeptical. Ginseng is not a drug and should not be taken as such. It is classified by the Food and Drug Administration (FDA) as a “generally recognized safe food” (GRAS).
