Both American ginseng and Asian ginseng are commonly referred to as simply ginseng, but Asian ginseng has been more commonly used in scientific research. Though ginseng's use for treating health complaints dates back more than 2,000 years, modern researchers have just begun to explore the scientific basis of ginseng's traditional benefits. As with any herbal remedy, ginseng can have strong effects, including side effects, so it's wise to check with your health care provider before making ginseng part of your health regimen.
Boosting the Immune System
According the University of Maryland Medical Center, there's some evidence that Asian ginseng can help improve your immune system function, reducing your risk for catching colds and infections and helping speed up the recovery process when you do get sick. Though early studies are promising, more research is needed to confirm these benefits.
Managing Blood Sugar
American ginseng may help people with type 2 diabetes manage their blood sugar levels, according to the University of Michigan Health System's Healthwise Knowledgebase. Taking a small amount of ginseng with high-glucose food and drinks may help control sharp spikes in blood sugar these products usually generate, but studies have been small and shown some contradictory results, so more research is needed to confirm these benefits.
Improving Heart Health
Though more research is needed, the antioxidants in ginseng combined with the herb's potential cholesterol-improving powers may benefit people who have cardiovascular health issues, according to MedLine Plus, an online health information resource maintained by the U.S. National Library of Medicine and the National Institutes of Health.
Boosting Mental Clarity
Ginseng, especially in combination with Ginkgo biloba, may help improve concentration, memory, critical thinking and general alertness, according to the University of Maryland Medical Center. Though early studies show promise, this type of research can be difficult to quantify and studies are often poorly designed. Further investigation is needed to confirm these benefits.
