Trump D Syrup 100 ml, a member of the class of drugs known as "cough and cold medicines," is to cure dry cough. The body uses coughing, whether it is productive or dry, to remove irritants from the airways and guard against infection. Dry cough and chesty cough are the two different forms of coughs. A chesty cough (wet cough) means mucous or sputum is generated to help clear your airways, but a dry cough is tickly and doesn't produce any nasty or thick mucus.Disclaimer:For more information contact your physician.
