American Ginseng Affects Postprandial Glucose Response

KEY POINT

Patients who do not have diabetes perhaps should take doses of American ginseng with meals—rather than between them, as is usually recommended by practitioners of Asian medicine. A recent study shows that agent mutes the body’s postprandial glucose spike when ginseng is taken as little as 40minutes before ingestion of a glucose load.
