Glabridin

Glabridin is a chemical compound that is found in the root extract of licorice (Glycyrrhiza glabra).[2] Glabridin is an isoflavane, a type of isoflavonoid. This product is part of a larger family of plant-derived molecules, the natural phenols. Glabridin effectively inhibits platelet activation, so it might become therapeutic agent for thromboembolic disorders.[3]
