The general rule for the treatment of phlegm and cough is “for those who suffer from phlegm and cough, warm medicine should be used to harmonize them” (Han-Zhang Zhongjing, “The Essential Formula of the Golden Horoscope”). However, based on my years of clinical experience and study of ancient Chinese medical literature, I believe that the chapter of “Jin Kui Yao Yao – Phlegm Drinking Cough Disease with Pulse and Evidence” is not about “phlegm evidence”, but about “drinking evidence”. In other words, “for those who are sick with phlegm and drink, warm medicine should be used to harmonize them” is the general rule of treatment for drink evidence, while phlegm evidence also has cold phlegm, but always has hot phlegm in the majority, and treatment advocates clearing, which is worlds apart from drink evidence treatment, and if not observed, can easily lead to the change of deficiency. Yan Yongbin, Department of Pediatrics, The First Affiliated Hospital of Henan College of Traditional Chinese Medicine, because the lung is the source of water, the external evil dry, easy to produce drinking evil, drinking into phlegm, so that the lung disease is difficult to heal, so drinking evil is an important pathological basis for the early stage of pediatric lung disease, and is the metabolic products, in the occurrence, development and regression of lung disease plays an important role. The author’s clinical evidence, pediatric lung disease in the early stages of the drinking evil in seven or eight, and hot drinks and eight or nine, but “cold drinks easy to know, hot drinks difficult to know” (Cheng Menxue language), thus affecting the efficacy of Chinese medicine treatment of such diseases, and make the drink brewed into phlegm, the disease is prolonged. Early identification and treatment of hot drinks can not only have a rafter effect, but also cut off the reversal, prevent changes in both diseases, promote the improvement and innovation of the Chinese medicine diagnosis and treatment system for pediatric lung diseases, and carry forward the idea of “treating the untreated” in Chinese medicine. Therefore, clinical identification of hot drinks and is particularly important, my view is to identify phlegm drinks, to refer to modern medical tools, that is, the heart of the Chinese reference to the West. Identification is the basic principle of Chinese medicine to understand the disease, is also a special method of Chinese medicine to identify the disease judgment, is through the look, smell, ask, cut the collected information, symptoms and signs, through analysis, synthesis, judgment for some kind of evidence, in order to explore the nature of the disease. However, due to the limitations of scientific conditions, the four diagnoses of ancient Chinese medicine are only based on the perception and experience of the five senses, and sometimes it is difficult to discover deep or potential pathologies, which has great limitations, which is not only a problem that the ancient sages could not foresee, but also a problem that our contemporary Chinese medicine cannot avoid. Therefore, in today’s highly developed modern technology, it is necessary to reasonably apply modern diagnosis and treatment techniques to further extend the four diagnoses of TCM, in order to make up for the shortcomings of TCM diagnosis, which not only does not deviate from the way of TCM identification, but also complements and perfects the system of identification and treatment. Therefore, the author believes that the key point of identification of hot drink evidence is to refer to the Western medical auscultation, i.e., to make reference to Western medicine, specifically in the following three aspects: First, lung auscultation Smell diagnosis is a method to diagnose disease by listening to sound and smell, which is one of the important methods of Chinese medicine to diagnose disease, such as “Nei Jing” said “smell and know is called sage”. In ancient times, Chinese medicine practitioners only “smelled” diseases by their ears and nose, but in modern times, with the help of stethoscope, it is a further development of ancient Chinese medicine diagnosis, to improve the level of “smelling” diagnosis of internal sounds. According to the author’s clinical experience, the wet sound (i.e. blistering sound) heard with the help of the stethoscope is considered by Western medicine to be related to the obstruction of the airway with thin and clear secretions, which is similar to the so-called “clear and thin is drinking” in Chinese medicine, and is judged to be drinking evidence. On the contrary, the dry rhotic sound heard is considered by Western medicine to be related to sticky phlegm adhering to the airway, which is consistent with the so-called “thicker phlegm” in Chinese medicine, and is judged as phlegm evidence. Secondly, the clinical symptoms of pulmonary disease and drinking evidence are more complicated, in fact, both heat and drinking evidence are available, but they are the same as the simple heat and cold drinking evidence, and also have essential differences from the phlegm-heat evidence. The main manifestations are fever, coughing and salivation, mouth full of fluid, taste light but not fishy, dry mouth but not desire to drink, irritability, or with vomiting, abdominal distension, diarrhea. Because of heat, so fever, irritability, dry mouth, because of drink and heat, so dry mouth but do not want to drink, coughing and salivation, thin quality, light taste and not fishy odor or with vomiting, abdominal distension, diarrhea, etc. are all drink evil within the stop of the Hou. Third, the tongue and pulse The typical tongue and pulse of children with lung disease with hot drink evidence is a light tongue with a slight yellow coating and a tight or numbered pulse. The “phlegm” of the world.
