Ashwagandha

Withania somnifera

Ayurveda's greatest adaptogen — a root that builds stress resilience, supports the thyroid, and restores deep vitality.

At a glance

Pungent, earthy, and slightly bitter with a faint horse-like note (hence the name). Root powder in warm milk mellows into something almost malted.

Tradition

Ashwagandha has been the backbone of Ayurvedic rasayana (rejuvenation) medicine for at least 3,000 years. The Charaka Samhita, one of Ayurveda's foundational texts, prescribes it in milk as a tonic for fatigue, emaciation, and vata-type anxiety.

Modern evidence

Over 30 clinical trials now support its effects on perceived stress, cortisol, sleep quality, and athletic recovery. The most studied extracts (KSM-66, Sensoril) are standardized to withanolide content. Effect size for anxiety and cortisol reduction is modest but consistent.

How to use

The traditional route — root powder stirred into warm whole milk with honey and a warming spice — remains one of the best for bioavailability. Capsules work well too. Most effects become apparent after 4–6 weeks of daily use.
