A dry cough — non-productive, without mucus — arises from airway irritation and hypersensitivity rather than active infection. The most common cause is post-viral airway inflammation that persists weeks after apparent recovery. Constitutional homeopathy often accelerates resolution of this stubborn cough significantly faster than spontaneous recovery.
What Causes Dry Cough?
Post-viral airway hypersensitivity (after influenza, COVID-19, or common colds) is the most common cause of persistent dry cough. Other causes include ACE inhibitor medication (a side effect in up to 20% of users), GERD with laryngopharyngeal reflux, post-nasal drip from chronic sinusitis, asthma (cough-variant), and — less commonly — interstitial lung disease or cardiac causes. The classic post-viral dry cough is triggered by cold air, exercise, speech, eating, and strong odours.
Post-Viral Cough and Airway Hyperreactivity
After viral respiratory infections, many patients develop persistent dry cough from ongoing airway inflammation and hypersensitivity that outlasts the infection itself. The airways become so sensitive that even cold air, a sip of water, or speaking triggers coughing bouts. Conventional treatment with cough suppressants and inhaled corticosteroids provides partial relief. Constitutional homeopathy — selected precisely for the individual's specific trigger pattern and constitutional picture — often produces resolution faster than spontaneous recovery.
Homeopathic Remedy Selection
The character of a dry cough varies significantly between patients, and this variation is diagnostically important for remedy selection. A cough exclusively triggered by cold air, coming in from outdoors, or a change in temperature points toward different remedies than a cough worse lying down, or one triggered by speaking or singing. Associated symptoms — tickling throat at a specific location, hoarseness, heartburn, nasal drip — further refine the prescription.
Key Remedies
Rumex Crispus suits an incessant dry cough triggered specifically by cold air or breathing cold, with a sharp tickle in the throat pit at the suprasternal notch — covering the throat while going outside is a characteristic feature. Bryonia addresses a dry, painful cough where every bout causes chest wall pain and the patient holds the chest while coughing. Phosphorus suits a burning, tight chest with persistent dry cough worse lying on the left side. Drosera is specific for spasmodic, convulsive coughing bouts ending in retching, particularly in children.
