Discriminatory treatment is the characteristic and essence of Chinese medicine. Diagnosis of diseases by evidence is a proper and special content of diagnosis in TCM, it is the main basis of legislation and prescription, the basic principle of understanding and treatment of diseases in TCM, a special method of research and treatment of diseases in TCM, and one of the basic features of TCM. The evidence is a generalization of the pathology of the organism at a certain stage in the process of disease development. It includes the location, cause, nature of the disease and the relationship between positive and evil, reflecting the essence of the pathological changes at a certain stage in the development of the disease, thus it reveals the essence of the disease more comprehensively, profoundly and correctly than the symptoms, for example, hyperactivity of liver yang and damp-heat. Another concept that needs to be clarified is the “symptoms”, such as fever, headache, yellow tongue coating, and counted pulse. Identification is to analyze and synthesize the information, symptoms, and signs collected from the four diagnoses (look, smell, ask, and cut) to determine a certain disease. To discuss treatment is to determine the corresponding treatment method. Therefore, the treatment methods are different for different symptoms of the same disease, while different diseases can be treated by the same method as long as the symptoms are the same, which is “different treatment for the same disease and different treatment for the same disease”. This rule of using different methods to solve different qualitative contradictions in the process of disease development is the spirit of discriminatory treatment. To differentiate and treat patients according to their different symptoms, they are identified as different certificates in TCM and are treated flexibly. With evidence-based treatment, TCM diagnosis and treatment of diseases can highlight the word “live”, which requires TCM doctors to grasp dynamic people and dynamic diseases in the dynamic cosmic weather, apply TCM theory of the unity of heaven and man and evidence-based treatment, accurately grasp the best balance between the human body and heaven and earth, skillfully adjust the balance of human yin and yang, and finally turn Because of the flexibility and creativity of TCM, it is possible to treat these diseases even without a clear diagnosis of the disease name as long as one correctly grasps the discriminatory treatment. Therefore, for both known and unknown diseases, as long as there are symptoms, a treatment plan can be formulated and treated in a timely manner, which is one of the greatest characteristics of Chinese medicine. The following methods of identification are commonly used in clinical practice: the eight principles of identification, identification of qi, blood and fluid, identification of the internal organs, identification of the six meridians, identification of the body, qi and blood, identification of the three jiao, and identification of the meridians. Identification of disease and evidence: disease, that is, disease, is a complex and pathological process caused by pathogenic factors in the human body under certain conditions, with certain forms of expression and pathogenesis. Evidence, that is, the evidence, is the pathological generalization of the body at a certain stage in the process of disease development. It includes the cause of disease, disease location, disease nature and the relationship between evil and positive, reflecting the nature of pathological changes at a certain stage in the development of disease. Since disease refers to the whole process of disease, while evidence reflects the essence of pathological changes at a certain stage of disease, evidence is more specific, relevant and operable than disease. Identification is to take the information, symptoms and signs collected from the four diagnoses (looking, smelling, asking, and cutting), analyze, synthesize, and identify the cause, nature, location, and relationship between evil and positive aspects of the disease, and generalize and judge it as a certain kind of evidence. The purpose of treatment is to determine the corresponding treatment based on the results of the identification. After the diagnosis of the disease is determined, the principle of treatment is determined according to the disease. For simple diseases, it is easier to identify and treat the disease, such as the application of deworming agents for ascariasis. However, most diseases are relatively long processes in which the pathological changes vary at each stage, making it difficult to determine a uniform treatment method. Therefore, treatment guidelines can only be determined based on the evidence, not the disease. This is the reason why Chinese medicine treats evidence more often than disease. For example, in the early stage of wind-heat, with fever and slight wind aversion, wind-heat is on the surface and should be treated by the method of cooling the surface. In the later stage, the fever has subsided, the tongue is red and the mouth is dry, the cough is dry with little phlegm, and the pulse is weak and fatigue. In the later stage, the fever has subsided, the tongue is red and the mouth is dry, the cough is dry with little sputum, and the pulse is weak. In contrast, sometimes the same or similar pathological changes occur in different diseases, i.e., the same or similar evidence appears, and according to the principle of discriminatory treatment, the same treatment can also be applied to different diseases, and this situation is called different diseases with the same treatment. For example, after prolonged diarrhea, prolapse of the anus occurs, which belongs to the lowering of the middle qi; while after improper postpartum conditioning, prolapse of the uterus also belongs to the lowering of the middle qi, so both patients should be treated with the treatment of benefitting the qi and raising it.
