Cough Suppressants
Coughing is an important reflex as it helps to expel mucus from the lungs, keeping them clear. Coughing is also annoying and can make it difficult to work ad to sleep. Cue cough suppressants, which work by inhibiting the coughing reflex. In doing so, they help to reduce the number of times that you cough, making it a bit easier to get through your day and to sleep at night.
The most common ingredient that suppresses the cough is called dextromethorphan, usually listed as DM on the bottle. Other cough suppressants inclide camphor, eucalyptus oil and menthol.
