Traditional Chinese medicine believes that lung accumulation is due to deficiency, and deficiency is solid, which is a disease with deficiency in essence and solid in essence. The formation and development of pulmonary accumulation are closely related to the decline of healthy qi and the invasion of exogenous pathogens.
Exogenous pathogens invade the lungs first; The disease stays too much and forms nodules.
Exogenous pathogens, especially pathogenic factors such as wind, cold, summer heat, dampness, dryness, fire and epidemic disease, are also called "exogenous six pathogens".
"The lung is covered by the five internal organs", and it is generally believed by medical scientists in past dynasties that the invasion of external evils attacks the lung first; "Qi belongs to the lung", and the lung governs the whole qi. When foreign evil invades, attacking the lung first will disturb the lung qi, resulting in qi stagnation and qi inversion.
In Huangdi Neijing, it is mentioned that "the most virtual person is the place where guests are evil". Invasion of exogenous pathogens consumes lung qi. Pathogens are most likely to stay in virtual organs, such as phlegm, blood stasis, dampness and poison. When the healthy qi of the human body is insufficient, these pathogens in the body are difficult to discharge and easy to stay in the body. These pathogens will form nodules over time.
Qi deficiency provides an opportunity for the invasion of exogenous pathogens.
Congenital deficiency of vital qi or acquired factors lead to lung qi deficiency, leading to vital qi failure. Su Wen Wen Re points out that "the combination of evils leads to deficiency of qi", and the reason why exogenous evils can invade the human body and cause diseases must be that their vital qi in the human body loses first. In other words, if it is not a person with weak vital energy in the body, these exogenous evils cannot harm the human body alone.
The formation of pulmonary nodules is a slow process, so the course of treatment is also long and slow. The treatment method adopted by Chinese medicine is usually to fundamentally adjust the overall state, that is, the weakness of vital qi.
