Coughing is an act which helps to clear the foreign particles from the throat and the airway, where the foreign particles are usually germs, irritants, or mucus. It can be voluntary as well as involuntary. Coughs are of two types—productive and non-productive. A productive cough or wet cough involves phlegm and mucus whereas a non-productive cough or a dry cough does not include any phlegm and mucus.

According to the American Lung Association, dry cough is a persistent medical condition for many individuals in the country.
