Abstract Summary
Objective
To evaluate the evidence behind Ashwagandha’s impact on psychological stress, cortisol regulation, cognitive clarity, and sleep quality.
Context
Ashwagandha (Withania somnifera) is an adaptogenic herb used in traditional Ayurvedic medicine to balance the body’s stress response. Its key compounds, particularly withanolides, modulate the hypothalamic-pituitary-adrenal (HPA) axis, reduce cortisol levels, and promote neurotransmitter balance. This results in calmer mood states, enhanced focus, and improved stress tolerance.
Methods Used
Approach
Systematic review of clinical trials and meta-analyses assessing Ashwagandha’s effects on stress, mood, cognition, and sleep.
Data Collection
Data included changes in cortisol levels, Perceived Stress Scale (PSS) scores, sleep quality indices, and cognitive task performance following supplementation.
Researchers’ Summary of Findings
Impact on Health
Multiple high-quality trials show Ashwagandha significantly reduces stress and anxiety scores and lowers cortisol levels, especially in chronically stressed individuals. Subjects also report improved sleep, better focus, and more stable energy.
Health Implications
Ashwagandha supports emotional and cognitive well-being by promoting hormonal balance and reducing stress reactivity. It is generally well-tolerated and beneficial when used consistently. Effects vary by individual response and extract potency.
Sustainability
Ethically sourced root-only Ashwagandha extracts grown using sustainable farming practices ensure potency while minimizing environmental impact.
