Treatment	Dose (mg/kg)	No. of writhing	% of inhibition
Control (Saline water)	10	59.80 ± 1.66	--
Diclofenac Na	10	27.40 ± 2.22**	54.18
VTA	200	41.40 ± 1.63**	30.77
VTA	400	34.46 ± 2.82**	42.37
VTM	200	40.90 ± 0.93*	31.60
VTM	400	32.84 ± 2.23*	45.08

Values are expressed as mean ± SEM; (n = 5). *p < 0.05, **p < 0.01 as compared with control. Data were processed with Dunnet’s test for multiple comparisons, GraphPad Prism for Windows, Version 6.0. VTA = V. tessellata aqueous extract, VTM = V. tessellata methanol extract.
