Dizziness is a common functional disorder of the brain, as a sensation of dizziness, head swelling, light-headedness, shaking in the brain, and blurred vision, and is one of the very common symptoms in clinical practice. There are also very many diseases that cause dizziness, such as the most common febrile diseases (e.g. exopathia), hypertension, cranio-cerebral diseases, cervical spondylosis, anemia, etc. There are very many causes of dizziness, but the mechanism of dizziness is especially important when it comes to stopping dizziness in the clinic, especially when it comes to persistent dizziness and emergency dizziness. Let’s listen to Dr. Zhong, who has read a lot of books and thought deeply about Chinese medicine, talk about some of his personal views on the mechanism of dizziness and share them with you. Vertigo is often encountered in clinical practice and can occur in many common diseases, such as hypertension, cervical spondylosis, Meniere’s syndrome, cerebrovascular disease, and so on. However, today I would like to discuss the main mechanism of the disease from the perspective of Chinese medicine. It is said in the Internal Canon that “all winds and dizziness belong to the liver”, “the dizzying wind is a recipe for deafness, the eyes are deaf, the lower is real and the upper is deficient, and the lower is in the foot Shaoyang and Turk’s Yin, and even the liver is involved”, and “the wood is depressed…even the tinnitus vertigo”. Ling Shu: “If the medulla is insufficient, the brain turns to tinnitus, the shins are sore and dizzy”. This shows that vertigo is related to liver, wind and deficiency. In addition, with the continuous development of medicine, the connection between dizziness and phlegm-dampness and water-drink has been gradually recognized. For example, in The Essentials of the Golden Horoscope, there are branch drinks under the heart, and people suffer from vertigo. Danxi Xinfa proposes that no dizziness is caused by phlegm. Jing Yue Quan Shu: “No deficiency does not make dizziness.” In the book, “The evidence of dizziness is that eight or nine of them are deficient, and only one or two of ten are fire and phlegm.” How should we analyze liver, wind, phlegm, fire, and deficiency? First of all, there is deficiency and there is reality. From the point of view of deficiency and qi-blood, dizziness is also deficiency and reality, deficiency is insufficient qi-blood and reality is too much qi-blood. This excess is not an overall excess, but a local surplus. That is, the Qi and blood are rebellious. From modern physiology, we know that the brain is the organ that is given the highest priority to provide blood, oxygen and nutrients, and it is also the organ that consumes the most energy and generates the most heat. Therefore, if there is a deficiency of qi and blood, the brain function will be affected first, and vertigo and other problems will naturally occur. This is what happens when there is an overall deficiency. When there is too much qi and blood, the brain becomes more loaded to operate and its function is affected. In this way, the brain, the source of qi and blood, the channels through which qi and blood enter and exit, and the dynamics of qi and blood operation and the regulatory system, outline the mechanism of vertigo in a more graphic way. If the brain works normally, there will be no vertigo, and if not, there will be various diseases. So then, looking at liver, wind, phlegm, fire and deficiency, it is obvious that the products of vertigo are understood from different angles and at different levels. In my opinion, the most important one is liver. According to the article 19 of the disease mechanism, “all winds and dizziness belong to the liver”, dizziness is a problem of the liver. However, it should be noted that why did the ancients not say that all winds and dizziness belong to the brain? As I said above, dizziness occurs when the brain is affected. The reason why we analyze this disease with the liver as the main body is that the liver is not the liver in the anatomical sense of modern medicine, but in the functional sense, and it is one of the five Tibetan; and the brain, as said in Neijing, is the brain, marrow, bones, gall bladder, women and cells, and these six are the birth of the earth’s qi, which are all hidden in the yin and like the earth, so they are hidden but not leaked. In a nutshell, the brain is the internal organs of Qi Heng. In general, the ancients regarded the human life activities and its connection with heaven and earth, the sun and moon, the stars, the universe, as a whole. Under this holistic view, the five subsystems of heart, liver, spleen, lung and kidney are subdivided to govern the rest of the body. In this way, it is clear that the functions of the brain are dispersed among the five major systems. 1, the liver, its physiological characteristics and physiological characteristics, has been systematically summarized in recent times, the liver is the main blood collection, the main drainage. The liver is the main reservoir of blood, and the main spreader of blood. According to the anatomy, the liver is actually a super large “blood ball”, which is the material basis for the blood collection function. Therefore, the liver can be the source of blood for most organs of the body. And because blood is the mother of qi, qi is dependent on blood, and qi is the handsome of blood, to help the blood line, common brain supply. 2.Where does blood come from? Qi and blood are basically generated by the spleen, stomach, heart and lungs, and then blood is stored in the liver, and gas is stored in the mushroom. As for the wind, it is generated by the flow of Qi and Blood, and in turn affects Qi and Blood transportation. Just as in nature, typhoons and hurricanes mainly come from the sea, the liver stores blood, which is naturally the sea, but it is worth noting that the sea of blood in the human body is the chong veins. Coincidentally, the Tanzhong point is a Ren lineage point, and the back section of the Chong lineage is combined with the Ren lineage. 3, qi and blood upward to rely on the liver, because the liver is the main drainage, with the nature of ascension and development. Under normal circumstances, Yin and Blood are descending, but in pathological conditions, Qi and Blood go up to the brain and produce vertigo. That is, it is said inside the Nei Jing: great anger extinguishes the flow of qi, and the blood reverses upward, causing a thin convulsion. How to rebel upward, with the wind, through the Sanjiao and meridian system up to the brain. 4. What is the relationship between the channels and the production of vertigo? If the channels are unobstructed, the Qi and blood will flow. However, if the channels are blocked, all kinds of diseases will arise. The blockage is usually considered to be phlegm-dampness and blood stasis. Phlegm-dampness is the product of abnormal metabolism of fluid, and fluid can be transformed with blood. Stagnant blood is blood that does not return to the meridian. Therefore, the blockage is transformed from the original circulation, which is generated in the heart, lungs, spleen and stomach, all related to the drainage function of the liver. After blockage, what needs attention is the generation of fire. There is originally fire everywhere in the body; without fire, life activities stop, and too much fire dries up the essence and blood. If the channel is blocked, there will be a relative imbalance of qi and blood in the body, which is equivalent to oil. In addition, where the blockage, it is possible to produce such as charcoal, oil, methane and other flammable high-energy things, so, the fire can not be prosperous carry on! Fire will be forced to blood delusion, blood flow naturally accelerated, fast is the wind.
