June 25, 2003 – Taking ginseng supplements may lead to a normalization of blood sugar levels in some diabetics, two new studies indicate.
The first, carried out by Canadian researchers, recruited 30 diabetics who were able to control but not normalize their blood sugar levels with modern medication. Some participants were given North American ginseng and fiber supplements three times a day for 12 weeks, while others were given a placebo. Then the two groups took a four-week hiatus before switching roles.
The researchers found that in patients who took ginseng and fiber supplements, hemoglobin A1C, the accepted measure of blood sugar levels, dropped to a level considered normal, but that was not the case with patients taking a placebo. Ginseng has also been shown to be safe, without dangerous side effects.
In the second study, other Canadian researchers found that Korean red ginseng would stimulate insulin production and improve insulin sensitivity, when compared to a placebo. Insufficient production of insulin or too low sensitivity to it could prevent an individual from adequately controlling their blood sugar level.
These studies remain small and it is therefore impossible to draw general conclusions. However, they are in addition to other small studies that have come to similar conclusions.
The researchers say that it is impossible to know if all diabetics would benefit from taking ginseng supplements, especially because the quality of products available on the market can fluctuate enormously. However, any diabetic patient who starts taking ginseng should tell their doctor, as too low blood sugar can be dangerous.
These studies have not been published, but were presented at a meeting of the American Diabetes Association.
