Among respiratory complications, cough is an important defensive pulmonary reflex that removes fluids, irritants or foreign substances from the respiratory tract. Rosa damascene Mill, petal extract is a traditional medicine and reported to use in the management of cough. In the present study rose petals extract samples were used to prepare natural antitussive cough syrups containing ivy leaf extract to observe synergistic effect of rose water in managing coughing in rats. Four cough formulations (A1, A2, A3 and A4) were prepared. The antitussive activity was observed at three dosage levels; 5ml, 10ml and 15ml. Cough was induced by the standard procedure using sulfur dioxide gas and ammonia. The antitussive activity was recorded by observing the coughing bouts. The result indicated that all formulations had a good effect on cough reduction at 90min but comparing the effect of formulations in all doses formulations, A2 followed by A3 and A4 at 30 minute time interval which is good in comparison with standard Diphenhydramine HCL and Dextromethorphan HBr 10ml in sulfur dioxide gas and ammonia induced cough. Hence, the results of the present study indicated the synergistic effect of rose water in the management of cough ailments.
