Scientific Research on Ginseng
- Previous studies, including research from the University of Toronto, have shown that Panax ginseng may lower blood glucose in conditions associated with diabetes.
- In a study at the Minnesota Mayo Clinic, terminal cancer patients taking a higher daily dosage of ginseng reported less weakness and fatigue than those taking lower dosages or placebos.
- Other experiments indicate possible beneficial effects on immune function due to its anti-carcinogenic, anti-inflammatory, and antioxidant properties.
- Results from scientific research on the health benefits of Asian ginseng remain inconclusive to date. The contradictory data from different studies may be attributed to varying types and quality of ginseng being analyzed. Few extensive clinical trials on Asian ginseng have been conducted. Most studies have been selective, lack statistical analysis, or have flaws in experimental design.
- Some previous studies were only conducted with animal subjects. For example, ginseng appears to inhibit cancer-related characteristics in animal models, but this effect is unclear in humans. Southern Illinois University School of Medicine found that Asian and American ginseng enhances sexual libido and activity in lab animals.
