Overview
Emodin is an anthraquinone from rhubarb and other plants with preclinical evidence for metabolic, anti-inflammatory, and anti-cancer effects; restricted in some markets due to laxative effects.
Mechanism & Function
Mechanism of Action
Inhibits 11β-HSD1 (reducing local cortisol activation), activates AMPK, modulates inflammatory cytokines, and acts as mild laxative at higher doses.
Physiological Role
Used experimentally in metabolic and body composition stacks; UK MHRA restricts laxative anthraquinone use; safety profile cautious.
Primary Pathways
Performance / Health Relevance
Mostly preclinical; limited high-quality human RCTs; some safety concerns at high doses.
