The diagnosis of diseases in TCM is based on the identification and treatment of the disease name and the type of evidence before the prescriptions and medicines can be administered. The names of diseases in TCM, such as cough, croup, asthma, phlegm, palpitation, heartache, sleeplessness, etc., are all names of the main symptoms. The “evidence” in identification is also a generalization and summary of symptom groups as a whole, and then the essential changes of disease location, disease nature, disease potential and disease development and regression. Then, there are six meridians, internal organs, body qi and blood, and qi, blood and fluid systems, all of which describe, summarize and identify symptoms from different perspectives. Therefore, diagnosis, as the basis for treating diseases, is closely related to the symptoms of the patient. The earliest explorations of TCM therapeutics originated from the ameliorating effects of selected acupuncture points and drugs on symptoms. Knowing the genus of points and medicines, understanding the nature of points and medicines, identifying the length of points and medicines, being familiar with the combination of points and medicines, understanding the use of points and medicines, and making the best use of points and medicines to give full play to the role of TCM in treating disease. For example, the origin of the A is point, according to the Tang dynasty Sun Simiao “Thousand Gold Essentials” mentioned: “A is the method, that people have a disease pain, that is, pinch it, if the place when it, do not ask the hole, that is, it will become pain, that is, the cloud A is. Moxibustion stabbing lend experience, so the cloud is the point also.” In other words, the use of needles may not necessarily be stuck in the acupuncture points. If effective, zap in the right place, if you can achieve the effect then you can. These special pain points are called “aye-points”. In the Ling Shu Jing Tendon, it is said that “the pain is the point of infusion”, i.e., the location is based on the location of the pain and the external symptoms. Following the words of Yuan Dou Hanqing, “Yang F Yang Wei and the Governor’s vein, to the heart and abdomen and the rib in the suspicion, the viscera disease and seek the door sea Yu collection of micro, meridian stagnation and seek the original other rendezvous way, more poor four roots and three knots, according to the specimen and prick no cure, but with eight methods and five doors, divided into the main guest and the needle is not effective, eight veins always even eight will, this is the outline, twelve meridians and twelve original is called the pivot. ” However, generations of acupuncture point works are detailed in the acupuncture point main treatment only list the name of the disease, and neglected to analyze the role of the point in the main treatment of the disease and application methods. The medicine speaks of “Shennong Ben Cao Jing” cloud: “Dansha, taste sweet, slightly cold. Main body five organs of a hundred diseases, nourishing the spirit, the soul, the benefit of Qi, bright eyes, kill the essence of the evil ghosts. Long serving, through the gods, not old”; “kudzu root, taste sweet, flat. Main thirst, body great heat, vomiting, all paralysis, up Yin Qi, detoxification of all poisons”. Although later generations have improved the positioning of acupuncture points to the meridian and acupuncture point examinations, as well as the theory of the nature of taste and meridian of drugs, but its landing point is still the improvement of specific symptoms, such as the “Materia Medica Preparation” cloud: “Astragalus: tonic qi, solid table, diarrhea of fire, sweet and warm. Raw use of solid surface, no sweat can send, with sweat can stop. Warm the flesh, the coup, diarrhea yin fire, solve muscle heat. It is used in roasting to tonify the middle, benefit the vital energy, warm the three jiao, and strengthen the spleen and stomach. Generating blood and muscle, draining pus and internal support, the holy medicine for sores and carbuncles”. The targeted ameliorative effect of a single drug as a unit of treatment for a specific symptom is the basic point that needs to be clarified when using medicine. The prescription canon also contains a lot of content based on symptom treatment. In the “Treatise on Typhoid Fever”, it is said, “In typhoid fever, there is the evidence of Chai Hu, but you can see one evidence, not all of them are necessary.” The “evidence” of “but see a certificate is” refers to the symptoms of the disease that are specific to the prescription, and is the indication for choosing the main prescription. In the specific use of prescriptions as the main body of treatment, it is also necessary to select them according to the symptoms.
