TCM Treatment of Obstructive Emphysema
Obstructive emphysema falls under the category of chronic obstructive pulmonary disease (COPD), characterized by incomplete reversible airflow limitation. Its pathological basis is chronic inflammation and structural changes in the terminal bronchioles and lung parenchyma, ultimately leading to airway narrowing and progressive increase in airflow resistance. Traditional Chinese Medicine (TCM) does not have this exact name, but related discussions exist in conditions such as "cough," "shortness of breath," "phlegm-dampness," and "lung distention," particularly closely related to "lung distention" in etiology, pathogenesis, clinical presentation, disease progression, and prognosis. Generally, in early stages, the disease affects the lungs; in mid-stage, it impacts the spleen; in late stages, it involves the heart and kidneys. Pathological factors include wind, phlegm, blood stasis, heat, water, dampness, and toxic turbidity. The pathogenesis is typically a mixture of deficiency and excess, with qi deficiency, blood stasis, and phlegm obstruction being the most common syndromes. Treatment follows a staged approach (acute exacerbation phase vs. remission phase), classifying by syndrome characteristics, yielding good clinical results. Below is a brief overview of medication and differential diagnosis:
One, Wind-Heat Invading Lung, Lung Losing Function of Dispersion and Descent
This type commonly appears in the initial stage of COPD exacerbation, often triggered by external wind-heat pathogens. Symptoms include cough, shortness of breath, wheezing, chest tightness, difficult expectoration, sticky or yellow-thick phlegm, often accompanied by aversion to wind, fever, headache, thirst, and yellow nasal discharge. Tongue coating is thin yellow, pulse is floating rapid or floating slippery.

Two, Phlegm-Heat Blocking Lung, Both Qi and Yin Damaged
This type commonly appears in the acute exacerbation phase of COPD, especially in those with recurrent episodes prone to lung abscess (bronchiectasis). Symptoms include shortness of breath, chest tightness, cough, shortness of breath, abundant sticky yellow phlegm, difficult to expectorate, sometimes with a foul odor or blood streaks, accompanied by dry mouth, constipation, irritability, insomnia, fatigue, weak speech.

After phlegm is expectorated, cough stops. Phlegm is white or grayish, viscous or thick and clumped, accompanied by chest tightness, epigastric fullness, nausea, poor appetite, fatigue, loose stools, pale tongue with dark color, white greasy coating, fine slippery or soft slippery pulse.

In summary, obstructive emphysema is commonly characterized by deficiency of the root and excess of the branch. The root deficiency primarily involves qi deficiency, qi-yin deficiency, and spleen-kidney yang deficiency, while the branch excess mainly involves phlegm, blood stasis, wind, and heat. During acute exacerbation, treat the branch first; during remission, treat both root and branch, balancing deficiency, phlegm, and blood stasis. For severe COPD with right heart failure or respiratory failure, combination of TCM and Western medicine is essential to quickly control symptoms and prevent further deterioration.
