Data are presented as mean (mm)±standard deviation (SD) (n=6/group). Groups of mice were pre-treated with vehicle (control group, oral administration, n=6), diclofenac (50 mg/kg, oral administration) or lemon grass essential oil (LGEO) at doses of 10, 40, 100, and 200 mg/kg (oral administration, n=6/group) 30 min before carrageenan-induced paw edema. LHP: left hind paw; LGEO: lemon grass essential oil. Means within the same column followed by the different letter are significantly different (P<0.05) according to ANOVA one-way analysis followed by Tukey's post hoc multiple comparison test.
