Cough:

The cough reflex consists of three phases: an inhalation, a forced exhalation against a closed glottis, and a violent release of air from the lungs following opening of the glottis, usually accompanied by a distinctive sound. Coughing can happen voluntarily as well as involuntarily, though for the most part, involuntarily.

Frequent or severe coughing usually indicates the presence of a disease. Many viruses and bacteria benefit by causing their host to cough, which helps to spread the disease to new hosts. Coughing is classified as acute (of sudden onset) if it is present less than three weeks, sub acute if it is present between three and eight weeks, and chronic when lasting longer than eight weeks. A cough can be dry or productive, depending on whether sputum is coughed up. Most of the time, coughing is acute and caused by a respiratory tract infection.

Coraxicum RA-21 is a very effective product in acute cases of Cough Patients.
