Reviewed guidance
Several trials suggest that some standardized ashwagandha extracts taken for weeks may reduce stress symptoms, but findings are inconsistent and products vary. One meta-analysis found improvement in perceived stress, while another found lower cortisol without a clear perceived-stress benefit. Ashwagandha should not be presented as an immediate rescue remedy.
Optional short-term adjunct for adults dealing with an identifiable stressor that persists for several weeks, using a standardized ashwagandha root extract comparable to studied products; not an immediate calming remedy and not a substitute for evaluation of persistent anxiety or depression.
How to use it: If considering ashwagandha for a stressor that lasts for weeks, use a clearly labeled standardized root extract rather than converting study doses into tea, food, or powder recipes. Reassess the underlying stressor and seek professional help if symptoms persist, worsen, or interfere with work, sleep, relationships, or daily function.
Avoid ashwagandha during pregnancy and breastfeeding. It is not recommended around surgery or for people with autoimmune or thyroid disorders without clinician review. It can cause drowsiness, stomach upset, diarrhea, or vomiting; rare liver injury has been reported. Review use with a clinician if you take sedatives, anticonvulsants, thyroid medicines, immunosuppressants, diabetes medicines, or blood-pressure medicines.
Get medical care for symptoms that are severe, last longer than expected, get worse, or otherwise concern you.

Later meta-analysis found a cortisol reduction but no significant perceived-stress improvement, preserving the conflicting evidence rather than overstating efficacy.

Herbal supplementation remains secondary to practical stress management and should not delay evaluation of severe or persistent symptoms.

NCCIH states that some ashwagandha preparations may help stress and supplies the principal liver, pregnancy, thyroid, autoimmune, surgery, sedation, and medicine-interaction safety boundaries.

Meta-analysis of nine randomized trials found lower perceived stress, anxiety scores, and cortisol, but the evidence base was small and heterogeneous.
