Uses
Escin (CAS NO.6805-41-0) is responsible for most of its medicinal properties.It is a safe and effective treatment for chronic venous insufficiency. It induces release of prostaglandin,and also induces endothelial nitric oxide synthesis by making endothelial cells more permeable to calcium ions.Other possible mechanisms include serotonin antagonism and histamine antagonism and reduced catabolism of tissue mucopolysaccharides.
