Many herbs have certain anti-tumor effects. In vitro experiments and animal experiments have shown that the aqueous decoction or extracts of certain herbs have direct inhibitory effects on tumor cells, induce apoptosis of cancer cells, reduce inflammatory responses, block neovascularization in tumors, immunomodulatory effects, and regulate the microenvironment of tumor growth. Most of these herbs exert their anti-tumor activity through the mechanism of Chinese medicine such as clearing heat and detoxifying, activating blood circulation and resolving blood stasis, and supporting the root. Some patients listened to biased prescriptions and bought drugs such as white flowering snake’s tongue, half-root lotus and red bean curd to boil water and drink, hoping to cure their cancer, which is not scientific. The effectiveness of TCM is based on evidence-based treatment and holistic view, which not only requires evidence-based legislation according to the main characteristics of the disease, such as cold, heat, deficiency and actuality, but also takes into account the balance of yin and yang between internal organs and qi and blood, as well as the individual characteristics of the patient, the relationship between the person and the season and the living environment, i.e. the principle of “three causes and conditions” in TCM treatment. The principle of “three reasons for the appropriate” in Chinese medicine treatment: “according to the person, according to the time, according to the place and according to the appropriate”. Without evidence-based treatment, the soul of TCM treatment of diseases is lost. The mere piling of drugs not only cannot effectively treat tumors, but even likely to damage the body due to improper medication. For example, if patients with cold constitution take a lot of anti-tumor drugs of heat-clearing and detoxifying type, but fail to take into account the essential characteristics of the body’s Yang energy deficiency, it will lead to the aggravation of symptoms and deterioration of the disease. The effectiveness of Chinese medicine in the treatment of tumors is based on evidence-based treatment, which cannot be separated from the treatment principle of “supporting the righteous” and “eliminating the evil”. In the treatment, we should not only take into account the methods of “attacking evil”, “detoxifying” and “eliminating accumulation” to remove tumors, but also actively adopt the methods of “benefiting qi” and “nourishing qi” to address the deficiency of the body. To improve qi”, “nourish blood”, “nourish yin”, “support yang”, “regulate the internal organs “to gradually adjust the imbalance of the organism and help the body restore health. Therefore, it is feasible to use Chinese medicine to treat lung cancer. Then can Chinese medicine alone cure tumor or not? It should be said that up to now, both modern medicine and traditional Chinese medicine still have limited treatment for tumor, which is reflected in: 1) the pathogenesis is complex, with internal and external factors such as human factors (congenital deficiency, emotional and mental disorders, poor diet, excessive labor, etc.) and environmental factors (living environment, social factors, etc.) interacting with each other to develop the disease; 2) the identification and typing of tumor is often combined with deficiency and reality, which requires accurate identification and precise use of medicine. (3) The strength of the disease varies at different stages, so that “the disease is in the skin”, “in the couples”, “in the muscles” or “in the muscles”. In the lighter stages of the disease, Chinese medicine can be treated. In the light stage of the disease, TCM can play a good curative effect, such as actively using the combination of Chinese and Western medicine treatment and comprehensive rehabilitation methods, can help patients recover; after the end of Western medicine treatment, the use of TCM treatment and comprehensive rehabilitation can play a role in consolidating the efficacy, preventing recurrence and metastasis; but in the progressive stage of the disease, such as the disease is strong and the body is weak, the role of simple TCM treatment is mainly reflected in improving the symptoms, improving the quality of life. At this time, the appropriate treatment goal should not be “cure”, but “delay the progress and stabilize the disease”. Therefore, it is important to evaluate the efficacy of TCM objectively and not to be biased and blindly pursue a cure. Many clinical studies have shown that the combination of Chinese and Western medicine is still the best treatment option for malignant tumors. For lung cancer patients who have lost the opportunity of western medical treatment or western medical treatment is ineffective, it is practical to choose Chinese medicine treatment. When seeking TCM treatment, it is important to have an objective, fair and rational attitude. The strengths of TCM are to improve symptoms, enhance quality of life and prolong survival, and the efficacy is based on individualized treatment. It is recommended that patients who intend to use TCM treatment should seek medical consultation from qualified TCM oncology specialists, and not to listen to unlawful propaganda, so as not to delay the disease.
