What to know before use
A concentrated root, not a food. Traditionally taken in small amounts with milk or water for short periods. It is not suitable in pregnancy or breastfeeding, for children, or with thyroid, autoimmune or liver conditions without clinician review, and it can add to the effect of sedatives and thyroid medicines. Rare liver reactions have been reported, so stop and seek advice if nausea, itching, dark urine or yellowing appear.
Important cautions
Best used with guidance. Not suitable for everyone, especially with thyroid or autoimmune conditions.
Who should avoid it
- People with hyperthyroidism
- People with autoimmune conditions unless advised
- Those on sedatives
Medicine interactions
- Sedatives and sleep medicines
- Thyroid medicines
- Immunosuppressants
PregnancyTraditionally avoided in pregnancy unless prescribed by a qualified practitioner.
ChildrenNot recommended for young children without practitioner guidance.
Quality and buying guidance
Choose root-only powder from a licensed manufacturer — cheaper products may include leaf or stalk. Look for the botanical name Withania somnifera, batch number, expiry and, ideally, published heavy-metal and pesticide testing. Avoid unlabelled loose powders and combination "energy" blends of unclear content. Store airtight, away from heat and moisture.
What does the evidence say?
Some early laboratory or small human studies exist, but they are limited and not conclusive. Traditional use remains the main basis for this entry.
