Shamkuwar P B, Pawar D P.
Berberis aristata (family Berberidaceae) has been traditionally used as an ingredient of polyherbal formulations for the treatment of diarrhoea. Aqueous extract of stems of Berberis aristata (100, 200, 400 mg/kg, p.o.) was tested for its antidiarrhoeal and antispasmodic effect in mice. The method of magnesium sulphate (2 g/kg) induced diarrhoea were used to evaluate antidiarrhoeal activity, while charcoal meal test and castor oil induced intestinal secretions were used for testing antimotility and antisecretory activity in mice. Aqueous extract of Berberis aristata (BA) treated mice, significantly reduced the induction time of diarrhoea, number of wet stools and total no of stools in the diarrhoea induced by magnesium sulphate. It has also produced antimotility and antisecretory activity in castor oil induced intestinal transit and intraluminal fluid accumulation in mice. These results indicate that BA produces its antidiarrhoeal effect through decreasing intestinal secretions and antispasmodic effect through inhibiting the intestinal motility.
