PHLEGM HEAT IN THE LUNG
This pattern is similar to Damp-Phlegm in the Lungs, but with additional Heat features, such as feeling of heat, thirst and profuse sticky yellow or green sputum. The typical manifestations of Phlegm are the coughing, short of breath, Phlegm in the throat and chest oppression. The Phlegm can also obstruct the head and cause heaviness and dizziness.
There can be acute or chronic conditions. The acute cases are often caused by external Wind-Heat penetrating the Defense Qi and attacking the Lungs, which results in acute chest infection and fever.
If the acute conditions are not treated completely, then the external Wind-Heat lingers and settles down in the Lungs, and it can become chronic eventually. Prolonged Spleen Qi Deficiency can also cause chronic condition. It is because the impaired Spleen can not transform and transport Body Fluids properly and thus Dampness and Phlegm forms.
