There is no "lung nodule" in traditional Chinese medicine, and modern medicine thinks that this disease can be classified as "cough", "asthma" and "phlegm nucleus".

The disease is located in the lung and involves the spleen and kidney. Its basic pathogenesis is qi deficiency and phlegm and blood stasis blocking lung collaterals.

Factors such as exogenous six evils, injury from work and rest, improper diet, and internal injury of seven emotions can all lead to qi stagnation and water stagnation, which will hinder qi movement for a long time, and water and dampness will not gather into phlegm, and phlegm and qi will gather together for a long time, which will lead to blood stasis, invading the lung and chest from the outside, and phlegm and blood stasis will block the lung collaterals, resulting in stagnation.

The disease also involves the liver. The syndrome of this disease belongs to deficiency in essence and excess in substance. Its pathogenesis is characterized by qi stagnation and blood stasis, and phlegm and toxin are abundant. According to the difference of qi stagnation and blood stasis and phlegm coagulation, the methods of promoting qi circulation and removing blood stasis, resolving phlegm and detoxifying are adopted.
