Yohimbe is a tree that grows in Africa. The bark has been used to promote weight loss and to lower blood pressure. Yohimbe has also been used to improve sexual and athletic performance. It can be taken as a pill, powder, or extract.
There are no advised doses for yohimbe.
There is not enough data to support that yohimbe is helpful in treating health problems. We will review future studies as they are published.
Editorial process and description of evidence categories can be found at EBSCO NAT Editorial Process.
It may not be safe to take yohimbe. Seizures, stomach upset, and heart attacks are possible. Women who are pregnant or breastfeeding and children should not take yohimbe.1-5
