The Sanskrit name Ashwagandha translates, memorably, as 'smell of a horse.' Not because the root smells pleasant — it doesn't, particularly — but because consuming it was believed to impart the vitality, strength, and sexual vigour of the animal. In a culture that venerated the horse as the pinnacle of power and endurance, this was the highest possible praise for a medicinal herb.
Ashwagandha (Withania somnifera) has been in continuous clinical use for approximately 3,000 years. It appears in the Charaka Samhita as a premier Rasayana — a herb of the rejuvenation tradition, used to restore depleted vitality, extend lifespan, and enhance the capacity of body and mind.
In classical Ayurvedic medicine, Ashwagandha is classified as:
Brimhana: nourishing and building — it increases body mass, muscle, and Ojas Rasayana: rejuvenative — it reverses tissue depletion and premature ageing Vajikara: a virility tonic — it strengthens reproductive tissue (Shukra dhatu) in both men and women Balya: strength-giving — it supports recovery from illness, overwork, and chronic stress
The herb is classified as heating in potency (Ushna Virya), sweet and bitter in taste, and heavy in quality. It primarily pacifies Vata and Kapha doshas, making it particularly valuable for the depleted, anxious Vata type and the heavy, sluggish Kapha type. High-Pitta individuals should use it with some caution, pairing it with cooling substances like milk.
Ashwagandha's pharmacological profile is dominated by a class of steroidal lactones called withanolides, particularly withaferin A and withanolide D. These are found almost exclusively in Withania somnifera and are the primary compounds responsible for its adaptogenic, anti-inflammatory, and neuroprotective effects.
Additionally, the root contains:
Alkaloids (isopelleterine, anaferine, cuscohygrine): contribute to the nervine and sedative properties Sitoindosides: glycowithanolides that appear to be responsible for anxiolytic effects Withanine: the principal alkaloid, with muscle-relaxing properties Iron: one of the highest concentrations found in any medicinal herb
The concentration of withanolides varies significantly by plant part, growing conditions, and extraction method. This matters enormously in supplementation — a root powder will have very different withanolide content than a standardised extract like KSM-66 (5% withanolides) or Sensoril (10% withanolides).
Ashwagandha is among the most studied adaptogenic herbs in contemporary pharmacology. The research base is now substantial:
Cortisol and Stress: A double-blind, randomised controlled trial published in the Indian Journal of Psychological Medicine (2012) found that 300mg of KSM-66 extract twice daily over 60 days produced a 27.9% reduction in serum cortisol and a 44% reduction on the Perceived Stress Scale.
Sleep Quality: A study published in PLOS ONE (2019) found that ashwagandha root extract significantly improved sleep quality, sleep efficiency, and morning alertness in adults with self-reported insomnia.
Muscle Strength and Recovery: Research in the Journal of the International Society of Sports Nutrition found that ashwagandha supplementation over 8 weeks significantly increased muscle mass and strength in resistance training subjects, while also reducing exercise-induced muscle damage markers.
Thyroid Function: Preliminary research suggests ashwagandha may support thyroid hormone levels in subclinical hypothyroid patients, though this area requires further study.
Anxiety: Multiple RCTs demonstrate anxiolytic effects comparable to some pharmaceutical anti-anxiety agents in mild-to-moderate anxiety, without the dependence risk.
Beyond the molecular pharmacology, Ayurveda offers a more holistic explanation for why Ashwagandha works: it builds Ojas.
Ojas is the eighth and most refined product of digestion — the quintessence of all tissues, the substrate of immunity and consciousness. When the body has sufficient Ojas, it radiates: the eyes are bright, the skin is luminous, the mind is clear and calm, and the immune system is robust. When Ojas is depleted — through overwork, chronic stress, illness, sexual excess, grief, or poor nutrition — the system becomes vulnerable.
Ashwagandha is the premier Ojas-building herb in the Ayurvedic pharmacopoeia. It does not merely address a symptom. It nourishes the deepest tissue layer and, in doing so, strengthens every system above it.
The traditional Ayurvedic preparation is ashwagandha root powder (Churna) taken with warm milk, honey, and ghee — a combination called Ashwagandha Ksheerapaka (milk decoction). The fat-soluble compounds in the root are extracted more effectively in a fatty medium, and the milk buffers the heating quality for Pitta types.
For modern supplementation:
Root powder (1–3g daily): Lower withanolide concentration but contains the full spectrum of natural compounds in their original ratios. More aligned with traditional use.
Standardised root extract (300–600mg daily, 5% withanolides): Higher potency, more studied in clinical trials. KSM-66 is the most extensively researched extract.
Timing: Evening use tends to yield better sleep benefits; morning use with food supports energy and athletic performance.
Duration: Ashwagandha is a tonic herb best used over weeks and months, not days. Most studies observe significant effects at the 8–12 week mark. Ayurveda traditionally recommends it as part of a daily Rasayana protocol for sustained periods, not as an acute remedy.
Ashwagandha is among the safest herbs in the Ayurvedic pharmacopoeia, but certain situations warrant caution:
Pregnancy: Ashwagandha is traditionally contraindicated in pregnancy due to its uterine stimulant properties. Avoid unless under direct supervision of a qualified practitioner.
High Pitta conditions: Because of its heating potency, those with active inflammatory conditions (such as inflammatory bowel disease, active autoimmune flares, or intense heat signs) should use it with caution or pair it with cooling herbs.
Thyroid medication: Given the preliminary evidence for thyroid effects, those on thyroid hormone replacement should monitor levels if starting ashwagandha.
Immune-suppressive medications: The immunomodulatory effects may theoretically interact with immunosuppressants. Consult your physician if relevant.
Ashwagandha is a core ingredient in OKH Elements' Vata Calm Oil, combined with sesame and other nervine herbs for grounding and nervous system support.
