Ashwagandha has been used for many things over the last 3,000 years.
Potential uses of ashwagandha that have been researched include effects on stress, sexual function and fertility, athletic performance, cognitive performance, pain, fatigue, thyroid function, diabetes, hypercholesterolemia, and tuberculosis. Initial findings for some of these conditions have been promising, but more robust clinical study designs are needed before confirming its benefits.
