When Li Zhongzi discussed the causes of "accumulation" in "Required Reading for Medical Zong", he pointed out: "If the accumulation of healthy qi is insufficient, then evil spirits will stand in it." On the other hand, Zhang Jingyue obviously believed that weak and unbalanced people would accumulate diseases. Pneumoconiosis is mainly caused by deficiency of vital qi, imbalance of yin and yang, evil and toxin entering the lung by taking advantage of deficiency, the lung does not descend obviously, qi is unfavorable, blood circulation is not smooth, body fluid is lost, phlegm accumulates, phlegm congeals and qi stagnates, and veins stagnate, which leads to phlegm, blood, blood stasis and toxin cementation, and finally forms pneumatosis over time.
Deficiency of vital qi and dysfunction of zang-fu organs are the main internal causes of tumors. If lung cancer is not treated in time, it will damage lung qi, consume lung yin, make the body more healthy, and promote the further spread and development of cancer. In the early stage, the tumor is still small, healthy qi is still strong, and healthy qi is strong and evil is light. The principle of giving priority to attack, or making up for it with a big attack, or attacking first and then adjusting. In the middle stage, when the tumor develops to a certain stage, pathogenic factors are flourishing and healthy qi is also damaged, and most of them are in the stage of "evenly matched", so the principle of both attack and supplement should be adopted. In the later stage, the illness is serious, and the healthy qi is weak. "Deficiency of healthy qi and excess of evil" should be based on supplementing, or supplementing minor attacks, or supplementing before attacking, that is, "strengthening the healthy qi, so eliminating evil".
The data show that the patients with lung cancer in China are mainly middle-aged and elderly people, and most of them are in the middle and late stage when they are diagnosed. At this time, the lack of healthy qi is a major feature of patients, and early patients are common even after surgery. Therefore, TCM treatment should be based on strengthening the body resistance, supplemented by eliminating pathogenic factors and eliminating food stagnation, and strengthening the body resistance is based on the rise and fall of qi, blood, yin and yang of patients. Eliminating pathogenic factors is based on phlegm coagulation, qi stagnation, blood stasis and heat toxin, but it is more than enough. In recent years, the therapeutic principle of "nourishing health and eliminating oneself" has gradually become common sense. Traditional Chinese medicine treatment focuses on enhancing the body's immunity and anti-cancer ability, supplemented by anti-cancer Chinese medicine, so as to control tumors and improve symptoms.
