Antidiarrheal activity of P. spinosa hydroalcoholic extract, isovanillin, iso-acetovanillon and propantheline on mice with MgSO₄ induced diarrhoea (0.5 ml, 10% solution) in comparison with that of corresponding vehicle treated controls. Incident of diarrhoea were assessed as number of wet defecation following MgSO4 administration. Data are expressed as mean ± SEM, n=10 for each group. *P<0.05, ***P<0.001 in comparison with corresponding vehicle treated control group (Student's t-test).
