Many therapies target this function as a way to improve overall health. In this study, Korean red ginseng was used to see if it could improve blood sugar levels in those who had higher than normal levels.
Forty one adults, whose blood sugar was classified as impaired, were given either Korean red ginseng or placebo for 12 weeks. Blood measurements were taken at baseline and then again after the study.
Those receiving the Korean red ginseng had lower overall blood glucose and lower levels of insulin, signaling that the overall function was improved.
