Staying hydrated is the single most effective thing you can do for a cough — fluids thin mucus and keep the throat moist. Honey, particularly Manuka, has documented cough-suppressant properties and is well-evidenced for children’s acute cough. Steam inhalation with or without peppermint or eucalyptus can temporarily ease congestion and reduce coughing. Elevating your head at night helps stop post-nasal drip triggering night coughs. Ginger tea helps reduce airway inflammation. Licorice root and thyme have traditional use as expectorants. A persistent cough lasting more than three weeks, or one accompanied by fever, shortness of breath, or blood, should be assessed by a doctor — it may indicate an infection that needs treatment.
