This study (LINK HERE) reports that an easy-to-get herb, Maca (Lepidium meyenii), has some mild benefit in humans. Men with ED received 2400 mg of Maca or placebo. The investigators reported that “a small but significant effect of Maca supplementation on subjective perception of general and sexual well-being in adult patients with mild ED.”

 

It’s nice to report on actual data.

 

My personal (subjective) experience with Maca is that it has some effect on mood; I feel the world looks a little better when I take Maca regularly. I don’t know if this translates into any sexual benefits.
