Ashwagandha can help you reduce stress levels. Ashwagandha or Withania somnifera is in a group of herbs called “adaptogens”. Adaptogens affect the systems and hormones in the body that regulate a person’s stress response. Ashwagandha has a long history of use in traditional Indian, or Ayurvedic, medicine. A small 2019 clinical trial investigated the efficacy of ashwagandha for stress and anxiety. The 8-week study involved 58 participants with perceived stress. Each participant randomly received one of three treatments: Ashwagandha extract at doses of 250 milligrams (mg) per day or 600 mg per day, or a placebo. Participants taking ashwagandha showed less cortisol, the stress hormone, than those in the placebo group. Participants taking 600 mg of ashwagandha reported significantly reduced stress levels. However, participants who took the lowest dose of ashwagandha did not report a reduction in stress. In another 2019 study, 60 participants with moderate anxiety received 250 mg of ashwagandha or placebo for 60 days. Those who took the herb showed a significant reduction in some measures of anxiety, but not others. People can take ashwagandha in a tablet or liquid tincture form.
