Orivax

Orviax is a natural male enhancement supplement. Orviax credits its success to its proprietary blend of 11 herbal ingredients, including damiana, epimedium and gingko biloba, which are advertised as completely free of any side effects.

Orviax contains damiana, horny goat weed, ashwagandha root, avena sativa, ginkgo biloba, Korean ginseng, maca root, muira puama, saw palmetto, tribulus terrestris and l-arginine.

It might for some. Orviax contains horny goat weed, an herb reported to have some male enhancement properties. Ginseng also reportedly male enhancement effects. Ginsenoside, a chemical found in Ginseng, is believed to be the active ingredient. But many of Orviax's ingredients are also proven not to work, including maca root, muira puama and avena sativa. Although it was used in traditional Chinese and Indian medicine , it's been proven ineffective by various national studies. Some of these ingredients are also unsafe to take for some people.

Not for some. Ginseng can cause nausea, diarrhea, headaches, nosebleeds, sudden changes in blood pressure and breast pain in some users. Men on antidepressants should take extreme caution--ginseng can also cause mania if used with certain antidepressants. Ginkgo biloba also worsens bleeding, and should not be taken by people on anticoagulants.

Orviax makes big claims, but the evidence doesn't support them--in fact, only a few of its ingredients have been reported to have male enhancement properties. Orviax comes up short when it comes to efficacy, but goes long when it comes to side effects, something this supplement isn't short of.
