Ashwagandha (Withania somnifera) is a classical Ayurvedic rasayana herb, often called an adaptogen. It's traditionally used to help the body cope with stress, restore energy and vitality, support restful sleep, and build strength — especially for Vata and Kapha types. It's taken as a powder, usually with warm milk.

Ashwagandha — its name means 'smell of the horse', hinting at the strength it's said to give — is a small shrub whose root is the part used. It has been used in Ayurveda for thousands of years as a grounding, restorative tonic.

How it's used in Ayurveda

In Ayurveda ashwagandha is classed as a rasayana (rejuvenator) and a nervine that calms Vata. It is warming and grounding, traditionally given to those who are depleted, anxious, overworked or sleeping poorly, to rebuild strength and steadiness.

Traditional benefits

Ashwagandha is traditionally used to reduce the effects of stress, support steady energy and stamina, encourage sound sleep, and nourish the muscles and nervous system. Modern research into it is ongoing and generally supportive of its calming, stress-easing reputation.

How it's taken

The root powder (churna) is the classic form — commonly half a teaspoon stirred into warm milk with a little honey or ghee at night, or taken as tablets or a standardised extract. It's often used in courses of a few weeks.

Cautions

Ashwagandha is best avoided in pregnancy, and anyone on thyroid, sedative, immunosuppressant or blood-sugar medication should check with a doctor first, as it may interact. It is a nightshade, so avoid if sensitive. Buy from a reputable source.
