This study reports that
“arginine, yohimbine, Panax ginseng, Maca, and Ginkgo biloba all have some
degree of evidence they may be helpful for erectile dysfunction.
Improvements in penile endothelial L-arginine-nitric oxide activity appear
to be a unifying explanation for the actions of these naturally occurring
agents.”

Erectile dysfunction affects 50 percent of men ages
40-70 in the United States and is considered an important public health
problem by the National Institutes of Health. Consumers are exposed to a
plethora of natural products claiming to restore erection and sexual
vitality. A review of the available empirical evidence reveals most
naturally occurring compounds lack adequate clinical trials to support
efficacy. However, arginine, yohimbine, Panax
ginseng, Maca, and Ginkgo biloba all have some degree of evidence they may
be helpful for erectile dysfunction. Improvements in penile endothelial L-arginine-nitric
oxide activity appear to be a unifying explanation for the actions of these
naturally occurring agents.
