Cough caused by exuberant phlegm. A phlegm cough is a heavy turbid-sounding cough characterized by copious phlegm that is easily expectorated and relieved by expectoration. It is associated with oppression in the chest, reduced food intake, white slimy tongue fur, and a slippery floating pulse. It is attributed to phlegm-damp brewing internally and ascending to affect the lung.
