The short answer
Some small studies suggest ashwagandha may reduce stress and anxiety in the short term, but the research is limited. It can cause stomach upset and, rarely, liver injury, and it isn't safe during pregnancy. It's not a treatment for an anxiety disorder.

Several small, short-term studies suggest ashwagandha may help reduce stress and anxiety. The studies vary in quality and dose, and long-term safety isn't well established.

Side effects

The most common are stomach upset, diarrhea and drowsiness. Rare cases of liver injury have been reported.

Who should avoid it

The bigger picture

If anxiety is affecting your daily life, talk to a doctor or therapist. Anxiety disorders are common and treatable. In a crisis in the US, call or text 988.
