What is Pure Nutrition HORNY GOAT WEED - 60 Capsules? Horny goat weed is a traditional Chinese medicinal herb. Some people claim it can help treat erectile dysfunction and osteoporosis. People used the herb as an alternative medication for: • hay fever • atherosclerosis • nerve pain • fatigue • osteoporosis • erectile dysfunction Human research data to support the use of horny goat weed is limited at best. However, some anecdotal evidence and animal and cell studies claim health benefits. Health benefits of HORNY GOAT WEED - 60 Capsules? • Erectile Dysfunction Quality research is lacking, but some evidence suggests horny goat weed can help males who have certain types of sexual dysfunction. Horny goat weed contains a substance called icariin. Icariin can block a protein linked with erectile dysfunction called phosphodiesterase type 5 (PDE5). PDE5 basically limits the increase in blood flow to the penis that is needed for an erection. Erectile dysfunction happens when there's not enough blood flowing to the penis. Normally, the body curbs PDE5 levels. In people who have erectile dysfunction, PDE5 might not be controlled the way it should be. Scientists found that icariin acts in the same way as Viagra (sildenafil) by blocking PDE5 activity. However, the action was weak, even in a test tube study. Compared to icariin, Viagra was 80 times more effective. That’s not to say horny goat weed won't improve a man’s ability to have an erection. The supplement may increase blood flow enough to trigger an erection in people who have mild to moderate erectile dysfunction. • Bone and Joint Health Phytoestrogens are plant-based estrogens found in horny goat weed and other plants. They can imitate the action of estrogen. Low estrogen levels after menopause can cause bone loss. Some alternative medicine practitioners suggest phytoestrogens can help treat this bone loss. Horny goat weed wasn't linked with any negative effects that women experience when taking estrogen, such as endometrial hyperplasia (irregular thickening of the uterine wall).  Horny goat weed is an herbal supplement that some people use to treat erectile dysfunction and stimulate sexual arousal. Some research suggests it has other positive effects, especially on bone health. People who have certain conditions shouldn't take this supplement.
