Other studies show that the herb Epimedium (commonly called ‘Horny Goat Weed’) helps sexual performance in several ways.

It functions as an adaptogen, increasing the level of various hormones including serotonin, dopamine, epinephrine, and norepinephrine when they fall below certain levels. This promotes higher energy levels and reduces the ‘stress hormones’ (cortisol) that depress sex drive and causing fatigue.

Epimedium also contains a number of flavonoids (plant compounds found in many green plants), one of which is known as icariin. Icariin can have a direct effect on erections. In medical terms, it is known as "a cGMP-specific PDE5 inhibitor", which are main ingredients contained in prescription drugs like Viagra, Cialis and Levitra.

Other ingredients in VigRX include both Ginseng and Ginko, both of which have hundreds of clinical studies (many institutions in many various different countries) that show their effects on the human body, not the least of which are improved circulation to peripheral circulation (body extremities), and increased libido and sexual function.

With drugs like Viagra, the pharmaceutical companies must provide clinical proof that their products are safe, and therefore spend little or no attention on the natural alternatives. There is, however, a growing body of knowledge that proves that the natural alternatives are effective!

VigRX ingredients have sufficient medical backing (as well as centuries of historical proof) to qualify VigRX as a totally viable and effective natural alternative, especially if you desire to spend less and/or avoid the potential side effects of Viagra.
