Aescin or escin is a mixture of saponins with anti-inflammatory, vasoconstrictor and vasoprotective effects found in Aesculus hippocastanum (the horse chestnut). Aescin is the main active compound in horse chestnut, and is responsible for most of its medicinal properties.

High-quality evidence suggests aescin is a safe and effective treatment for chronic venous insufficiency.^[1]^[2] In one randomized controlled trial, horse chestnut extract was found to be as effective and well-tolerated as use of compression stockings.^[3]

Mechanism of action

Aescin appears to produce effects through a wide range of mechanisms. It induces endothelial nitric oxide synthesis by making endothelial cells more permeable to calcium ions, and also induces release of prostaglandin F_2α.^[4]^[5]^[1] Other possible mechanisms include serotonin antagonism and histamine antagonism and reduced catabolism of tissue mucopolysaccharides.^[1]
