Catarrh

Catarrh or catarrhal inflammation, is a disorder of inflammation of the mucous membranes in one of the airways or cavities of the body. It can result in a thick exudate of mucus and white blood cells caused by the swelling of the mucous membranes in the head in response to an infection. It is a symptom usually associated with the common cold and chesty coughs, but can also be found in patients with infections of the adenoids, middle ear, sinus or tonsils. The phlegm produced by catarrh may either discharge or cause a blockage which may become chronic.The word "catarrh" is common to Appalachia where medicinal plants have been used to treat the inflammation and drainage associated with the condition.
