Figure 1: Effect of ethanol extract of Nasturtium officinale on carrageenan-induced paw edema in rats. The extract (250, 500, and 750 mg/kg, p.o.), and indomethacin (10 mg/kg, p.o.) were administrated 45 min prior to carrageenan (1%) injection. The paw thickness was evaluated 4 h after carrageenan injection and the values represent the mean ± SEM increased in the paw thickness, n = 6. ###P < 0.001 Indicates significant difference compared to the saline group and ***P < 0.001 versus carrageenan group.
