A discharge of fluid from a mucous membrane. The ancients considered catarrh as a simple flux, and not as an inflammation. Generally it partakes of this character, however. Catarrh is, with us, usually restricted to inflammation of the mucous membrane of the air-passages: the French extend it to that of all mucous membranes; (F.) Flux muqueux. Fluxion catarrhale. Catarrh, in the English sense, Broncho catar'rhus, Pul'monary Catarrh, Lung fever (vulgarly), Rheuma Pec'toris, Destilla'tio Pec'toris, Catar'rhus Pec'toris, C. Pulmo'num, C. Pulmona'lis, C.

Catarrhe pulmonaire, Fievre Catarrhale, Rhume de Poitrine, is a superficial inflammation of the mucous follicles of the trachea and bronchi. It is commonly an affection of but little consequence, but apt to relapse and become chronic. It is characterized by cough, thirst, lassitude, fever, watery eyes, with increased secretion of mucus from the air-passages. The antiphlogistic regimen and time usually remove it. Sometimes, the inflammation of the bronchial tubes is so great as to prove fatal.

Inflammation of a mucous membrane with free discharge; chiefly used of the nose and pharynx and of the bladder, etc.
