Phlegm-Damp Obstructing the Lungs
This is a disease name that refers to the obstruction of phlegm-dampness in the lungs, preventing the lung qi from descending and dispersing. Symptoms include a cough with abundant phlegm that is white and thin, easily expectorated, a feeling of fullness and oppression in the chest, exacerbation of cough with movement, wheezing with phlegm, a white greasy or slippery tongue coating, and a soft and slow pulse.
Pathogenesis
This condition is often caused by spleen qi deficiency, prolonged coughing damaging the lungs, or invasion by external cold-damp pathogens. When external pathogens invade the lungs, the lung’s ability to disperse and descend is disrupted, leading to stagnation of fluids that transform into phlegm-dampness. Spleen qi deficiency fails to transport and transform fluids, causing water and dampness to accumulate into phlegm, which is stored in the lungs. Additionally, prolonged coughing can weaken the lung’s function to transport fluids, resulting in dampness accumulation. All three causes can lead to phlegm-damp obstructing the lungs, causing lung qi to rebel upwards, hence the symptoms of cough with abundant phlegm that is white and easily expectorated. The obstruction of phlegm dampens the airways, leading to poor lung qi flow, resulting in chest oppression and, in severe cases, wheezing with phlegm. The pale tongue with a white greasy coating and slippery pulse are signs of internal phlegm-damp obstruction.
Clinical Manifestations
Symptoms include a cough with abundant phlegm that is sticky, white, and easily expectorated, chest oppression, and in severe cases, wheezing with phlegm, a pale tongue with a white greasy coating, and a slippery pulse.
Diagnosis
1. Cough and wheezing often recur, with a prolonged course, differing from new onset due to external pathogens invading the lungs.
2. The symptoms of phlegm-damp are prominent, characterized by abundant phlegm that is sticky, white, and easily expectorated, wheezing, greasy tongue coating, and a slippery or wiry slippery pulse.
3. Lung symptoms include cough, wheezing, and chest oppression.
Dialectical Treatment

Prevention and Care
1. Regularly prevent cold and keep warm; change clothing with climate changes. Those with weak constitutions can take Yu Ping Feng San (Jade Windscreen Powder) to prevent external pathogens.
