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

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...
