Cough
a spasmodic effort, attended with noise, to expel from the air passages of the lungs some foreign body or irritating matter, which else would injure the delicate respiratory apparatus. Properly speaking it is not a disease; it is the effort of nature to remove what, if it be allowed to remain, may generate one; or it may be the symptoms of a disease of the lungs, the liver, the stomach, or the intestines; or may be produced by the over-excitability of the system in the nervous temperament. At the same time, when itself violent, it may produce morbid effects.
