American ginseng improves glucose tolerance in diabetics and nondiabetics

A small, randomized clinical study showed that treatment with American ginseng (Panax quinquefolius) helped improve glucose tolerance in nondiabetic people as well as those with type II diabetes mellitus. For the study, 10 nondiabetic people and 9 people with type II diabetes received treatment with 3 g ginseng or placebo capsules either 40 minutes before or in combination with an oral glucose challenge. In nondiabetic participants, no difference was observed in glycemia between placebo and ginseng when the substances were administered along with glucose, but significant reductions were seen when ginseng was taken 40 minutes before the glucose challenge. However, compared with placebo, both ginseng dosage regimens improved glucose tolerance in the people with diabetes. The researchers cautioned that for nondiabetics, "to prevent unintended hypoglycemia, it may be important that the American ginseng be taken with meals." They also noted that the 3 g dose of ginseng used in their study is higher than that used in most other clinical studies, which is typically 1.5 g or less. Vuksan V, Stevenpiper JL, Koo VYY, et al.
