Acute Bronchitis & Cough

Reviewed by the Nimbera editorial team · Last updated May 2026

Natural and evidence-backed remedies for acute bronchitis, productive cough, and airway congestion. Most acute bronchitis is viral and self-limiting over 1-3 weeks. These remedies target mucus clearance, airway inflammation, and cough severity.

When to see a doctor

See a doctor if you have cough lasting more than 3 weeks, coughing up blood or yellow-green sputum, fever above 38.5 C / 101.3 F, shortness of breath at rest, chest pain, or if you are over 65, immunocompromised, or have underlying lung disease.
