Botanical extract (mixture) · Fact sheet
Ashwagandha
Also known as Withania somnifera
Ashwagandha is a botanical extract with small trials suggesting stress and sleep benefits. Preparations vary, and drowsiness, gastrointestinal effects, thyroid concerns, and rare liver-injury reports complicate broad wellness claims.
What is Ashwagandha?
Ashwagandha is a plant, not a single molecule or peptide. Root and leaf preparations contain mixtures of constituents, so product-specific results should not be assigned to all extracts.
Benefits people look for
Stress relief, sleep, lower cortisol, and testosterone-related claims are common. A change in a stress questionnaire or hormone does not establish benefit for every associated condition.
What the evidence supports
- Some short trials suggest improvements in stress or sleep with specific preparations.
- Evidence does not establish a universal anxiety treatment, reliable hormonal enhancement, or long-term safety.
All research areas
- Perceived stress
- Sleep
- Stress-related hormone measures
Anecdotal reports & lived experiences
Reports describe what someone noticed. They cannot establish cause, typical results, or how often a side effect happens.
Lower perceived stress, but feeling emotionally flat
A person described less stress after starting ashwagandha alongside feeling neither happy nor sad and unusually emotionally neutral.
This selected account does not establish a diagnosis, mechanism, prevalence or permanent effect. Formulation, other exposures and baseline symptoms were not independently assessed.

- Drowsiness, stomach upset, diarrhea, and vomiting are possible.
- Published case reports describe liver injury; they do not measure how often it occurs.
- Thyroid, autoimmune, pregnancy, and medication-interaction concerns are described by NCCIH.
This is a summary of the cited evidence, not a complete product label. A lack of human safety data does not establish safety.
Clinical research: how strong is it?
Early human evidenceA 64-person trial found lower stress scores with a particular root extract over 60 days. Small samples, varied preparations, and short follow-up limit generalization.
Selected research to read
64-person, 60-day randomized trial of a specific extract.
Five clinical cases; causality assessment, co-exposures, and follow-up limitations.
FDA approval & research status
Ashwagandha has no FDA-approved drug indication for the wellness uses discussed here. Supplement availability is not premarket FDA approval of effectiveness or safety.
No FDA-approved use is documented in the records summarized on this page.
Supplement research is not FDA drug approval
Ashwagandha has no FDA-approved drug indication for the wellness uses discussed here. Supplement availability is not premarket FDA approval of effectiveness or safety.
This summarizes the cited product or research record. Trial phases do not establish successful completion of earlier stages, and a stopped program is not ongoing development. Approval applies only to the labeled product, use and population.
What we still don’t know
- Which preparations reproduce trial results
- Long-term safety and the frequency of liver injury
- Meaningful hormonal or functional outcomes
The takeaway
Evidence does not establish a universal anxiety treatment, reliable hormonal enhancement, or long-term safety.
