Inhibitory Effects of Glycyrrhiza glabra and Its Major Constituent Glycyrrhizin on Inflammation-Associated Corneal Neovascularization

Figure 3

Representative photographs of CNV in G. glabra extract, glycyrrhizin, vehicle, and dexamethasone (positive control) treated group on days 0, 7, 14, 21, and 28. There is a gradual decrease in diameter and thickness of NV, and it almost vanished on the last day of experiment. The glycyrrhizin treated group also showed decrease in diameter and thickness of NV but the activity was lesser than the G. glabra extract.
