Evaluation of antiemetic effect of aqueous rhizome extract of Cynodon dactylon against all emetogenic stimuli

摘要

This study was an extension of our previous antiemetic work. Many researchers quoted Cynodone dactylon as anti emetic agent but none of them have provided strong pharmacological evidence for it, which drove us for its therapeutic evaluation. Crude aqueous rhizome extract of C. dactylon was evaluated for anti-emetic activity. Emesis was induced by the oral administration of copper sulphate, fresh aqueous extract of Brasica compestris while intravenous Cisplatin was used to induce emesis in fifteen days age chicks of either sex. The anti-emetic activity was determined by calculating the mean decrease in number of emesis in comparison to those of control and standards. C. dactylon (50 and 100 mg/kg body weight orally) showed remarkable emesis suppressant activity when compared with standard drugs chlorpromazine, domperidone and metoclopramide. Both the doses showed remarkable antiemetic activity.
