Erectile dysfunction (ED) is commonly called impotence. It’s a condition in which a man can’t achieve or maintain an erection during sexual performance. Symptoms may also include reduced sexual desire or libido. Your doctor is likely to diagnose you with ED if the condition lasts for more than a few weeks or months. ED affects as many as 30 million men in the United States.
* Panax ginseng
Called the herbal Viagra, Panax ginseng (red ginseng) has solid research behind it. Researchers reviewed seven studies of red ginseng and ED in 2008. Dosages ranged from 600 to 1,000 milligrams (mg) three times daily. They concluded there was “suggestive evidence for the effectiveness of red ginseng in the treatment of erectile dysfunction.”
* Rhodiola roseaOne small study indicated that Rhodiola rosea may be helpful. Twenty-six out of 35 men were given 150 to 200 mg a day for three months. They experienced substantially improved sexual function. This herb has been shown to improve energy and reduce fatigue. More studies are needed to understand action and ensure safety.
* DHEADehydroepiandrosterone (DHEA) is a natural hormone produced by your adrenal glands. It can be converted to both estrogen and testosterone in the body. Scientists make the dietary supplement from wild yam and soy.
* AcupunctureThough studies are mixed, many show positive results when acupuncture is used to treat ED. A 1999 study, for example, found that acupuncture improved the quality of erections and restored sexual activity in 39 percent of participants.
* YohimbeThis supplement is extracted from the bark of the African yohimbe tree. Some studies have shown positive effects on sexual performance with use of this drug.
