Ginseng root has long been used in Chinese medicine to address a range of ailments. The root is traditionally used as a tonic to improve energy, stamina, mental performance and improve immunity, however it can also be used for diabetes. There are two main species of ginseng—American ginseng and Asian or Korean ginseng—though the kind which is diabetes-specific is Korean red ginseng. This kind of ginseng has been proven to provide glycemic control, improve pancreatic cell function and enhance the uptake of blood sugar from tissues. When used in animal studies it has significantly decreased blood glucose levels, blood glucagon levels, and increased blood insulin levels. When performing similar studies on humans it was found that even in non-diabetics, ginseng impacted blood sugar levels. The inherent benefits of red ginseng can be further enhanced if it is fermented, since the live bacteria which result from the fermenting process helps optimize the absorption of ginsenosides within the ginseng. Beyond blood sugar control, red ginseng has also been found to provide antioxidant protection, an important element when dealing with diabetes. All these things combined make this herb a powerful diabetic, anti-hyperglycemic ally.
