Ashwagandha

Withania somnifera · winter cherry

Mechanism

Ashwagandha (Withania somnifera) is a classic adaptogen whose effect is attributed to withanolides. Human and rodent-model studies describe a reduction of stress and cortisol parameters as well as GABAergic and anxiolytic effects. Controlled efficacy and pharmacokinetic studies in the horse are practically absent, so transfer to the horse remains speculative. Because withanolides have centrally depressant/anxiolytic properties, the FEI status must be checked before any competition; adaptogenic/sedative botanicals may be captured as Controlled Medication. Note: Withania somnifera belongs to the nightshade family.

Cautions

· Horse-specific efficacy/PK data largely lacking
· Sedative/adaptogenic: check FEI status before competition
· Nightshade plant; use in pregnancy/lactation not sufficiently studied

How the Equiterna Score is built

The Equiterna Score combines three dimensions into a value of 0-100: science (40%), practical experience (30%) and safety (30%). It is transparently derived from evidence level, attributed sources (PubMed/journals), legal classification and cautions. The FEI doping status is shown separately as a competition-law note and does not enter the score. Commissions and vendor relationships have no influence on the score. In addition, the editorial safety rating caps the result: it limits the safety dimension and the overall tier (orange: at most solid). For entries rated red, no score is calculated at all. The rating never raises anything — a green rating does not lift a calculated value.

An editorial assessment of the evidence and safety situation — not a healing claim and not an individual recommendation. It does not replace veterinary advice.

DosageNo established equine dose; standardised root extract in practice approx. 5–10 g/animal/day for a large horse (~500–600 kg). Coordinate with a vet.
