Ashwagandha reduced serum cortisol by 27.9% compared to placebo in a double-blind RCT of 64 adults with chronic stress.
Ashwagandha (Withania somnifera) is classified as a rasayana in classical Ayurveda — an elite category of rejuvenating herbs intended for daily use. Modern researchers have identified its primary bioactives: withanolides, withaferin A[1], and alkaloids that modulate the HPA axis.
The adaptogen's ability to reduce cortisol has been replicated across multiple double-blind, placebo-controlled trials. A 2019 meta-analysis of 5 RCTs [2] found a standardized mean difference of -0.67 for perceived stress (PSS) — a moderate-to-large effect size.
☽ Ayurvedic Perspective
In classical Ayurveda, Ashwagandha pacifies Vata and Kapha doshas. The Charaka Samhita lists it as a primary rasayana for ojas (vital essence) and bala (strength).
☯ TCM Parallel — Ren Shen
While not part of classical TCM, Ashwagandha shares adaptogenic properties with Ren Shen (Panax ginseng). Both tonify Kidney Yang and support Shen (spirit/mind).
