Erectile Dysfunction and Korean Red Ginseng
Korean red ginseng is a heated form of Panax ginseng, one of the most popular species of the medicinal root.8 A handful of studies suggest that red ginseng may be a helpful treatment for erectile dysfunction.
Research Evidence on Korean Red Ginseng
Two double-blind, placebo-controlled trials, involving a total of about 135 people, have found evidence that Korean red ginseng may improve erectile function.1,2
In the better of the two trials, 45 participants received either placebo or Korean red ginseng at a dose of 900 mg 3 times daily for 8 weeks.2 After a 1-week period of no treatment, the two groups were switched. The results indicate that while using Korean red ginseng men experienced significantly better sexual function than while they were taking placebo.
In an analysis combining the results of 6 controlled trials, researchers found some evidence for the benefits of Korean red ginseng. However, the small size and generally low quality of the studies left some doubt about this conclusion.3
Side Effects and Warnings
Ginseng appears to be nontoxic, both in the short- and long-term, according to the results of animal studies4-7, but it is generally recommended that people with the following avoid ginseng: hypoglycemia, high blood pressure, heart conditions, asthma, and insomnia. Ginseng should also be avoided by women who are pregnant or breast feeding.8
