Both dry coughs and tickly coughs are known as non-productive coughs, as distinct from chesty coughs where mucus is produced.

A dry cough is most often the result of infection by cold and flu viruses. It can also be triggered by atmospheric pollutants (such as cigarette smoke) irritating your throat. In most of these situations, dry coughs occur because the back of your throat (or pharynx) becomes irritated or inflamed, but may also arise from deeper in the chest.
However, sometimes, specific cough remedies are needed to help ease the symptoms of a dry cough:
Home remedies such as honey soothe the lining of the tissues at the back of the throat.
Conventional medicines such as cough suppressants reduce the activity of the cough reflex. These may be prescribed by your doctor or available without a prescription from a pharmacy
Herbal remedies such as extracts of spruce or pine shoots are ideal for treating dry and tickly coughs coming from the throat
