(a) Anti-nociceptive activity of PAG (200 mg/kg and 400 mg/kg) and Diclofenac sodium (50 mg/kg) evaluated using hot plate method. All data are expressed as mean ± SD (n = 5), p < 0.001 (***) on comparison with control (only saline treated) group. (b) Anti-nociceptive activity of PAG (200 mg/kg and 400 mg/kg) and Diclofenac sodium (50 mg/kg) evaluated using acetic acid induced writhing test. All data are expressed as mean ± SD (n = 5), p < 0.001 (***) and p < 0.01 (**) on comparison with control (only saline treated) group.
