Traditional use and modern products
Withania somnifera has a long history in Ayurveda, but commercial powders, root extracts and root-plus-leaf extracts are not interchangeable. “Adaptogen” is a broad promotional term, not a diagnosis or guaranteed effect.
What current evidence suggests
Several small, short clinical trials suggest some preparations may modestly help perceived stress or sleep. Different extracts and doses make broad recommendations difficult, and long-term effectiveness is not established.
Safety and interactions
- Short-term use can cause stomach upset, loose stools, nausea or drowsiness.
- Rare liver injury reports require attention to jaundice, dark urine or severe symptoms.
- It may affect thyroid function and interact with thyroid, diabetes, blood-pressure, sedative, anticonvulsant or immunosuppressant medicines.
- Avoid during pregnancy; breastfeeding safety is insufficient.
- Discuss use before surgery and with autoimmune, thyroid, liver or hormone-sensitive conditions.
How to evaluate a product claim
Look for the plant part, extract ratio, standardisation, independent quality testing, dose and study matching the claim. A testimonial or “ancient” label is not proof of safety or effectiveness.
Plain answers
Common questions
What dose of ashwagandha should I take?
Studies use different preparations and doses, so this page does not prescribe one. Discuss the exact product with a qualified clinician or pharmacist.
Can ashwagandha replace anxiety or sleep treatment?
No. Do not stop prescribed care. Evidence is limited and serious or persistent symptoms deserve professional assessment.
