Chinese medicine is a profound and profound science with a long history, the pride of the Chinese nation, we must love it and pass it on. We Chinese medicine workers are duty-bound to shoulder the sacred mission of its inheritance and promotion. The classical works of Chinese medicine have always been throughout the holistic view of the unity of heaven and man; “Laozi? Chapter 25” says: “People follow the laws of the earth, the earth follows the laws of the sky, the sky follows the laws of the Tao, and the Tao follows the laws of nature”. Chinese medicine is the Tao of nature’s medicine, balanced medicine, generations of doctors are under the guidance of the Tao of nature theory, give full play to its wisdom, and the heritage to promote, so that the thousands of years and the life sciences. We live in nature, that is, from nature, which is the Tao of Chinese medicine. The Tao method of nature is unchanging to respond to all changes, is the highest human wisdom to solve difficult and complicated diseases. It is not allopathic medicine, not premised on killing bacteria and viruses, but on adjusting the balance of yin and yang in the human body with medicine, and the purpose of balance is to restore the natural state of the human body, getting rid of only the disease, but protecting the human body. In 2011, Harvard University had this to say about the Yin-Yang and Five Elements of TCM: “The Yin-Yang and Five Elements of TCM are the simplest philosophical model to describe the highly complex and open giant system of the human body.” The world-renowned sinologist and tenured professor at the University of Munich in Germany, Manqib, clearly states, “Chinese medicine is by far the most complete, coherent, and comprehensible representative expression of Chinese science. As such, it illustrates Chinese science with rich and readily available information and provides the most useful paradigm for establishing the univocity of expression in all life sciences.” The U.S. Food and Drug Administration document (FDA Regulatory Guide) states that “Chinese medicine is an independent scientific system with a complete theoretical and practical system, like mainstream Western medicine, and not merely a complement to mainstream Western medicine.” This is the fairest evaluation of the scientific nature of TCM in the West and the entire human world, and we cannot forget our ancestors and be presumptuous. At present, the westernization of Chinese medicine has taken over the mainstream of the Chinese medical profession, which of course has to do with the hospital management system and the misunderstanding of the public, but also has to do with the fact that when we diagnose and treat diseases, we have forgotten the magic weapon of discriminatory treatment, but first focus on the discriminatory treatment of diseases, which has fallen into the wrong path and greatly reduced the effectiveness of treatment. In terms of treatment, there are hundreds of thousands of prescriptions and prescriptions, but they are inseparable from the eight methods, “among the eight methods, a hundred methods are ready”. Zhang Zhongjing, the sage of medicine, said, “Look at the pulse and evidence, know what is wrong, and treat it according to the evidence.” This is a high summary of the scientific nature of Chinese medicine treatment, which has become the ancient method of Chinese medicine, if you can carefully grasp and apply, you can make complex diseases simple, simple to manage complex, this is the highest human wisdom to overcome disease. We can not know the disease, but we must not fail to understand the evidence, not to identify the evidence. To illustrate. In the 1960s, a young worker surnamed Wang, a native of Wuxi, suffered from periodic episodes of severe abdominal pain, when the abdominal pain was unbearable, rolling and howling on the ground, and had to be relieved by injecting dulcolax, which was relieved for 2 to 3 consecutive days. Later, he sought medical advice in Nantong. Medical records, a stack of test sheets, the diagnosis of “blood purple disease”, I did not know the history of this disease, I only from his face white light white less flashy, fatigue, the grain is not fragrant, waist and leg weakness, loose stools, timid cold times than normal, thin moss light, pulse is thin and slow. The evidence belongs to the deficiency of spleen and kidney yang and the blockage of yin and cold. The treatment is to warm the spleen and kidney, disperse the cold and relieve the condensation, so as to achieve the effect. Prescription: 9 grams of Phellodendron, 6 grams of ginger, 15 grams of Atractylodes Macrocephala, 9 grams of Radix Codonopsis, 9 grams of Ginseng, 9 grams of Radix Bupleurum, 9 grams of Radix Aromaticum, 9 grams of Radix Bacopa Monnieri, 3 grams of sand, 3 grams of licorice, three slices of ginger and five red dates. 7 doses, if there is a small effect after taking, it can be continued. At the time of consultation, it was the 10th day after the previous attack, and the decoction was asked to be taken to see its effect. The patient was afraid that he would have a seizure at that time, but after taking the decoction, he was very comfortable and did not have a seizure at that time, so his confidence was increased and he continued to take it. The patient’s face was slightly rosy and he was in good spirits when he returned to the clinic after a few months, so he was told to take one dose every day to consolidate the effect. In 2010, we met with a female patient surnamed Chen from Nanjing, who had periodic abdominal pain, causing fainting every time when she was in pain, with one attack in three to five days, and many examinations were inconclusive so far. Her face is yellowish, her chest is stuffy, her abdomen is distended, she sighs sometimes, her mouth is dry, she has trouble sleeping at night, her menstrual flow is low, she has difficulty in passing stools, and she has one line for several days. The coating is thin and greasy, the texture is dark red, and the pulse is thin and stringent. Because of her periodic abdominal pain, Yu thought of the similarity of symptoms in a patient with hemochromatosis in Wuxi, and on the one hand, administered medicine and on the other hand, asked her to further examine her urine in order to exclude hemochromatosis. As a result, the urine was found to be positive for urine violet, which confirmed the diagnosis of hemopurulmonary disease. According to his pulse, he was diagnosed as having deficiency of both liver and kidney, stagnant qi, and abnormal elevation. Prescription: Radix Rehmanniae Praeparata 15g, Radix Paeoniae Alba 20g, Radix Lycium barbarum 15g, Radix chasteberry 15g, Radix Shou Wu 20g, Radix Dendrobium Chuan 15g, Radix Glycyrrhiza Glabra 10g, Radix Erythrinae Sinensis 20g, Radix Angelicae Sinensis 10g, Radix Psidium Guadua 30g, Radix Citrus aurantium 8g, Radix Xu Changqing 15g, Radix et Rhizoma chenopodium 8g, Radix Glycyrrhiza Uralensis 8g. 5 doses. After two weeks, the abdominal pain was greatly relieved, the number of attacks was reduced, the interval was longer, there was no more syncope, the stool was smooth, and the night sleep was peaceful. The symptoms gradually slowed down, and changed to Liu Wei Di Huang Wan and Yi Yao Wan to consolidate the situation. It is also called hematoporphyria because of the disorder of porphyrin metabolism in the body and the increased production and excretion of porphyrins. I have been practicing medicine for more than 70 years and have only encountered these two cases, I did not know this disease, one case for the spleen and kidney Yang deficiency, one case for liver and kidney Yin deficiency, different types of evidence, but with the identification and treatment, were cured. It shows that identification is the primary and absolute, and identification is for reference only. The so-called “difficult disease” refers to the doctor in the clinical evidence, identification and treatment of the disease feel difficult, the problem lies in the identification of the “doubt”, the treatment of the “difficult”; in fact, the vast majority, or can be identified The key is how to master the law of identification and treatment, to find the essence of the evidence, identify “doubt” without confusion, treatment “difficult” without chaos, can be handy, to solve the difficult disease can be identified and treated. To sum up, we have to be people-oriented, through the four diagnoses, the Division of external speculation within, no matter how the disease changes, we just need to use the essence of diagnosis and treatment of Chinese medicine, we will be able to insight into the mystery of the disease, to see the microscopic, to develop the first opportunity to adjust the balance of Yin and Yang in the human body. My old friend, Comrade Guo Boxin, said: “Chinese medicine is an invisible science”, and I agree. Because the classical works of Chinese medicine are full of “great truths and scientific foresight”. We should seriously study the classics such as “Nei Jing” and “Treatise on Typhoid”, contact with clinical practice, find the lost “spirit” of Chinese medicine, and use it for me, we will be able to overcome many difficult and complicated diseases. “, I believe we still do not know enough. Although I am old, I would like to work with all colleagues to sharpen each other and strive to achieve “self-improvement, stopping at the best”, so that Chinese medicine can go global as soon as possible and prevent diseases and health care for all mankind.
