Figure 3.

Effects of eucalyptol on CFA‐induced mechanical allodynia in wild‐type and Trpm8^−/− mice, measured by von Frey hair analysis (administration as in Figure 1A). Testing was performed 26 h after CFA injection, 2 h after the mice received the third treatment of vehicle (Veh, corn oil), eucalyptol (Euc, 300 mg·kg⁻¹) or ibuprofen (Ibu, 30 mg·kg⁻¹). ^# P < 0.05, significantly different from control group; *P < 0.05, significantly different from CFA + Veh group, NS, no significance (P > 0.05), one‐way ANOVA. n = 6–12 mice per group.
