3000 年印度阿育吠陀

The name Ashwagandha comes from Sanskrit, combining 'horse smell' and 'strength of a horse'.

Foundational facts:

Latin name Withania somnifera, a Solanaceae shrubThe main medicinal part is the root; leaves and berries have different traditional uses and safety profiles3000 years of Ayurvedic use, in India, Nepal, and South AsiaAyurveda classifies it as a rasayana (rejuvenator / adaptogen), traditionally used to improve vitality, sexual function, memory, and longevity
On the concept of adaptogen, introduced by Soviet pharmacologist Lazarev in 1947 and systematized by Brekhman + Dardymov in 1969, with three defining features:

1. Non-toxic at normal doses
2. Non-specific — effective against multiple stressors
3. 'Normalizing' action — returns the body to homeostasis, whether starting from too high or too low

Classic adaptogens typically listed: ashwagandha, rhodiola, ginseng, cordyceps, holy basil, schisandra. The word has no formal FDA/EMA recognition and lives mostly in marketing and integrative medicine, but some of these plants do have RCT evidence — ashwagandha is among them.

Main active compounds

Withanolides: a class of steroidal lactones, ashwagandha's main pharmacologically active substance. Most-studied are withaferin A, withanolide A, withanone. Chemical structure resembles glucocorticoids, so partial effects may go through GR (glucocorticoid receptor) modulation; also acts on GABA / dopamine / serotonin systemsWithanosides: glycosylated withanolidesAlkaloids: trace amounts, used as a sedative in ancient India
Root vs leaf

Traditional use and most RCTs use root, because root has high withanolide content and few alkaloid impurities. Leaf extracts have higher withaferin A but also more cytotoxicity; some commercial products mix leaf and root, possibly explaining some adverse event reports. KSM-66, Sensoril and other proprietary extracts are standardized — see the next scene.
