In a randomized, double-blind, placebo-controlled trial 64 schizophrenia patients were assigned to take placebo or 500 mg of an ashwagandha extract for the first week and 1000 mg for the remaining 11 weeks of the trial.
Funding issues for this study:
The primary outcome was the severity of schizophrenia systems as assessed by PANSS. Participants taking ashwagandha saw a modest, statistically significant reduction in their total symptoms compared with placebo. They also saw a notable reduction in perceived stress. Markers of inflammation, hsCRP, and S100B declined in the ashwagandha group and increased in the placebo group, but the difference wasn't statistically significant. There was no change in IL-6. There was no significant difference in blood pressure or body weight between the groups at the end of the trial.
No statistically significant differences in adverse events were found between the groups.
