| − | However, problems getting an erection develop there is not enough nitric oxide. This unbalanced system makes it so the muscle in the erectile tissue remains flaccid [4]. Therefore, the bottom line is without sufficient amounts of nitric oxide you do not get an erection [8].

| − | Since nitric oxide is made from the amino acid L-arginine, researchers have used L-arginine supplements in the treatment of erectile dysfunction (ED) [7,9]. In one small trial of men with ED, participants were given arginine daily for two weeks [10]. At the end of the study period, 40% of the men in the treatment group reported an improvement in their erectile function compared to none in the placebo group.
| |
| − | In a larger, double-blind clinical trial, 50 men with confirmed ED took either L-arginine or a matching placebo [11]. After six weeks of treatment, 31% of the men taking the L-arginine supplement reported a significant improvement in their sexual function. It is interesting to note that all of the patients who reported positive results had low levels of nitric oxide before the study began and that these levels had doubled by the end of the treatment period.

| − | Because L-arginine is a supplement that is taken regularly, it works over time to increase nitric oxide concentrations. As a result, men are able to achieve a natural, spontaneous response to a partner’s stimulation without the need to take a prescribed pill in advance of sexual activity [7].

| − | In Asia, ginseng is one of the most commonly used herbs for the treatment of sexual dysfunction. This is because ginseng’s activity is thought to enhance physical performance, as well as sexual stamina [7].
| |
| − | Studies conducted with laboratory animals have shown that Asian varieties of ginseng enhance libido and sexual performance. According to researchers, there is good evidence that some of the chemical components of ginseng (known as ginsenosides) work to enhance erections by directly inducing the blood vessel widening and relaxation of the erectile tissue by enhancing the production of nitric oxide in the endothelium [12-16]. Ginsenosides also have heart protecting, immune stimulating, anti-fatigue and antioxidant properties that may also improve erectile function and have therapeutic actions in ED [13,17-20].

| − | Clinical research has shown that ginseng supplements are a good treatment option for men with ED. In one randomized study, 90 men with ED were divided into three groups and given either Panax ginseng, placebo or trazodone (an antidepressant) [21]. The researchers reported that the men taking the ginseng supplement had a significant improvement in erectile parameters such as penile rigidity, girth, duration of erection, improved libido and patient satisfaction. Overall, the ginseng improved erectile dysfunction by 60% compared to 30% for the other two groups.
| |
| − | In a more recent, double-blind, placebo-controlled, crossover study, 45 men with ED were divided into two groups and received either ginseng or a placebo (starch capsule with ginseng flavor) three times a day [22]. After eight weeks, ginseng supplementation produced a significant increase in erectile function and penile tip rigidity compared to placebo. The researchers speculated that the activity of ginseng for ED may include improvements in nitric oxide levels.

| − | Based on the available research it appears as though the therapeutic activity of ginseng is modest in comparison to the current treatment choices for ED. [http://www.vitalikor.com/site/order-page Vitalikor]
