Treatment	Dose (mg/kg)	Licking time (s)	Inhibition (%)
Control	0.1 ml/mouse	159.2 ± 5.74	-
Diclofenac sodium	10	12.20 ± 1.81*	95.10
MEPH	25	41.2 ± 4.92*	74.13
MEPH	50	31.2 ± 6.19*	76.92
MEPH	75	20.8 ± 4.10*	86.71

Each value is presented as the Mean ± SEM (n = 5). MEPH = Methanolic extract of P. hydropiper leaves.

*p < 0.001 compared with the control group (Dunnett’s test).
