This led to notable increases in muscle size between the ashwagandha vs. placebo groups.

Improving Erectile Dysfunction
Ashwagandha is frequently marketed as a natural treatment forerectile dysfunction (ED).
It is thought to help by increasing testosterone levels and by potentially acting as an aphrodisiac.
To date, the evidence supporting the claim is weak.
While some studies in rats suggest a benefit,research in humans has not yielded similar results.
This includes excessive levels of the hormoneprolactin, which ashwagandha appears to have no effect on.
Claims that ashwagandha is an aphrodisiac are also largely unsupported.
The evidence supporting the claims is strong.
Whether these effects translate to slowed or reversed aging is largely unproven.
Taking doses in excess of this may lead to stomach upset, diarrhea, and vomiting.
Despite its apparent safety, experts recommend that you consult with a healthcare professional before using ashwagandha.
As a result, some supplement products may not contain the ingredients listed on the label.
