Acute exacerbation of interstitial lung disease （AE-ILD） is one of the critical and severe respiratory conditions with a high mortality rate.

Professor WANG Yuguang， through extensive clinical practice， has summarized the main pathogenesis and treatment methods for AE-ILD， achieving remarkable therapeutic results in clinical applications. Professor WANG believes that AE-ILD， in terms of traditional Chinese medicine （TCM）， belongs to the category of "asthma collapse". The disease primarily involves the lungs， spleen， kidneys， and the triple energizer membrane， with the kidneys being the primary organ responsible. The main pathogenesis is characterized by a deficiency at the root and an excess at the manifestation. The deficiency of true primordial qi leads to a tendency for collapse， while pathogenic

obstructs lung

. Cold pathogens constrain lung

qi

， preventing its dispersal， which results in the transformation of body fluids into dampness， turbidity， and phlegm. The syndrome is characterized by the decline of primordial

qi

leading to collapse， the stagnation and accumulation of cold pathogens resulting in contraction， and the internal obstruction of dampness， turbidity， and phlegm triggering blockage. The treatment mainly focuses on restoring

and replenishing

qi

to prevent collapse， dispersing cold， and transforming dampness. The prescription chosen is a modified combination of
