What is the best home remedy for a dry cough?

Honey is a good home remedy for a cough, according to Healthline. Honey, which has a soothing effect, added to herbal tea or to a mixture of hot water and lemon juice — known for its decongestant properties — is a simple and effective treatment for a cough.

Dry coughs can persist after symptoms of the cold are relieved or may occur without any other symptoms. Hot, dry and dusty air can cause a dry cough. Chronic dry coughs are usually due to an allergic reaction, cigarette smoke, postnasal drip, asthma or environmental irritants, according to WebMD. In addition, gastric reflux can cause a chronic dry cough, often accompanied by heartburn, increased salivation and a burning sensation in the throat.
