Traditional use
Classified as a rasayana in Ayurveda, a rejuvenative taken over time rather than for an acute complaint. The root is the part used in classical preparations, traditionally given with warm milk at night. It appears in vajikarana formulations for vitality and in balya formulations for strength.
Why brands use it
Ashwagandha carries search volume comparable to major vitamins, in English and in Hindi. That demand is large enough that a single-herb capsule is usually a better traffic product than a blend containing it. Named grades such as KSM-66 matter commercially because the better-informed segment of the audience looks for them by name and checks the label.
Quality and specification
Root-only material is what the classical texts specify and what the research generally uses. Cheaper supply often includes leaf material, which has a different constituent profile. Standardisation is usually expressed as withanolide percentage, 5% is a common commercial grade.
Safety and cautions
Generally well tolerated. Traditionally avoided in pregnancy. May interact with thyroid medication and sedatives, and anyone with a thyroid condition or on sedatives should consult a practitioner. Not a substitute for prescribed treatment.
