Bronchiectasis(BE) is a chronic，progressive respiratory disease characterized by irreversible，permanent dilation of the bronchi.Therefore，blocking abnormal bronchial dilation is of significant importance.Based on the theory of “strong fire consumes qi”，this article discusses the pathogenesis of BE during different stages from both traditional Chinese medicine(TCM) and Western medical perspectives，combining microscopic and macroscopic viewpoints.In the acute phase of BE，the main pathological features are deficiency of healthy qi，an internal excess of “strong fire”，which obstructs and damages the collaterals，leading to the consumption of healthy qi.The core of this stage is the excessive “strong fire”.In the stable phase of BE，prolonged consumption of qi leads to hidden “strong fire” and the deficiency and damage of the collaterals，resulting in the subtle consumption of healthy qi.The main feature of this stage is the prolonged consumption of qi.Treatment should focus on clearing “strong fire” and supplementing “deficient qi” as a general approach.However，“strong fire” should not be cleared in isolation，nor should “deficient qi” be supplemented alone.Both supporting and expelling methods must be used in combination.During the acute phase，the focus is on the excess “strong fire”，and symptomatic treatment should prioritize clearing “strong fire” while supplementing “deficient qi”，with attention to syndrome differentiation.The appropriate treatment method should be tailored based on the predominant pathogenic factor to improve clinical efficacy，while considering the physiological characteristics of the lungs.In the stable phase，the emphasis is on “consumed qi”，and the primary treatment goal is to address the root cause.This involves supplementing “deficient qi” while clearing “strong fire” to prevent its recurrence，with the use of collateral-dredging drugs to target hidden “strong fire” in the lung collaterals.
