This article is to introduce Prof. WU Weiping’s experiences in treating interstitial lung disease

taking stage and syndrome as outline

taking symptom as detail

by adopting the differentiation mode of combining disease

syndrome and symptom. Prof. WU holds that dualism of lung flaccidity and lung Bi-syndrome should be applied when naming interstitial lung disease. The pathogenesis is deficiency of Qi and Yin and phlegm stagnation in collaterals.The key is deficiency

phlegm and stagnation. The disease location is lung and kidney. The treatment includes replenishing Qi and Yin

removing phlegm and stasis

and dredging collaterals. The disease is divided into three stages and six syndromes according to its progression. Seizing main symptoms

dealing with second symptoms

considering concomitant symptoms

according to tongue and pulse

as well as combing macroscopic and microcosmic view is emphasized when making syndrome differentiation.
