Viagra is one amazing drug used to address ED. It assists in 70-80 percent of cases of this disease. One of its important features is that it is dispensed only by prescription. You cannot find Viagra OTC, which would be legally sold, but you can buy some anti-ED supplements having the same effectsl. In this article, we’ll tell you about some of these alternatives.

L-arginine – boosts your blood flow

NO (nitric oxide) is a very important chemical that is utilized to make sure you are not bothered by erectile function. Scientists established that the synthesis of NO happens in all endothelial cells (including the endothelium of cavernous bodies) from L arginine under the action of the endothelial nitric oxide synthase enzyme. Due to complex biochemical reactions, NO indirectly cals down the smooth muscle cells, which leads to vasodilation and filling the penis with blood. One possible way to eliminate ED is to improve the synthesis of NO from L-arginine, which is the dominant substrate for the synthesis of NO. Arginine is a natural amino acid that is found in some food (cheese, other dairy products, meat, seafood, grains, and nuts). There are also many arginine-based supplements on the market.

Ginseng – a powerful Asian plant

Scientists from the Yonsei University in Seoul (South Korea) conducted a research involving 119 men with mild and moderate erection problems. Half of the participants took four pills containing extracts from the Korean ginseng berries on a daily basis; and, the rest took a placebo. After 8 weeks of treatment, they measured the improvement in the condition of men using the International Index of Erectile Function. The results of the study showed a small but significant enhancement of sexual function in men who took ginseng, ascompared with those who took a placebo.

Ginkgo biloba – a potent folk remedy

Ginkgo biloba is a relic tree, widespread in folk medicine. Extracts of the plant strengthen immunity, increase the elasticity of the blood vessels and stimulate the proper work of the reproductive system of men by normalizing the blood circulation in the area where genitals are placed. The plant extract also increases stress resistance, normalizes sleep and working capacity, makes a men more confident and significantly decreases nervousness before penetration.

Yohimbine – a strong erection and libido enhancer

Yohimbine

is an alkaloid from the bark of a Yohimbe tree (Pausinystalia yohimbe or Corynanthe yohimbe). By the mechanism of action, it is a selective blocker of central and peripheral α2-adrenergic receptors. In moderate doses, this substance causes dilatation of the pelvic arteries, which contributes to the improvement of erectile function (enhances the erection, prolongs the time of sex), as well as stimulates spermatogenesis. Due to the stimulating effect on the central nervous system, the substance increases motor activity and sexual desire. Studies have shown that yohimbine is particularly effective in cases of psychogenic ED, while PDE5-inhibitors are often ineffective in such instances.
