Stearyl glycyrrhetinate, a major component in licorice extract, has a MIC against S. aureus strains of more than 256 mg/L. Stearyl glycyrrhetinate has antibacterial effects^[1]. In Vitro: Glycyrrhetinic acid (GRA) and disodium succinoyl glycyrrhetinate (GR-SU) shows strong antibacterial activities compared to the other three agents tested. At a higher concentration (above 2x MIC), GRA and GR-SU shows bactericidal activity, whereas at a concentration of 1x MIC, they showed a bacteriostatic effect^[1].
