Biochem/physiol Actions
Glabridin is a bio-available isoflavan isolated from licorice (Glycyrrhiza glabra L.) root extract. Glabridin has been reported to posses varies biological activities including strong antioxidant activity, antioxidant against LDL oxidation, anti-Helicobacter pylori properties, estrogen-like activity and antinephritic and radical scavenging activities. Also it appears to inhibit serotonin re-uptake, melanogenesis, inflammation and cytochrome P450 3A4, 2B6, and 2C9.
