Coughing is the body’s way of removing irritating substances, excess secretions, and foreign objects from air passages. This is important, both as a protective mechanism and for the healing process—which is why a cough should not be artificially suppressed with drugs. Homeopathic medicines can soothe a dry or fitful cough, and loosen phlegm in a wet, productive cough. Coughing can accompany a wide variety of illnesses or conditions. Chronic cough or cough with difficulty breathing requires medical attention.
