Pattern Overview

Phlegm Wheezing is a common pattern in asthma, characterized by airway mucus hypersecretion, wheezing with phlegm sound, copious sticky sputum, and chest tightness. The core pathogenesis is Phlegm-turbidity obstructing the Lung, causing Lung Qi to fail to descend, mucus obstruction, and wheezing.

Western Mechanism Reference

Airway mucus hypersecretion with mucus plug obstruction of small airways, airflow limitation, and MUC5AC overexpression. Phlegm Wheezing corresponds to asthma with mucus hypersecretion, where goblet cell hyperplasia and MUC5AC overexpression contribute to mucus plug formation and airflow obstruction.
