The recent occasionally glanced at a blog post title, called “dangerous bloodletting therapy”, I often use bloodletting therapy, there is a need to read, or a look at the fight against counterfeiting hero Fang Zhouzi wrote, so look carefully down. After reading it, I couldn’t help but laugh at the original famous Mr. Fang’s knowledge is only half a bucket of water, but to shake very much. First of all, Mr. Fang does not know the history of Chinese medicine at all. Mr. Fang presumptuously claimed that “the bloodletting therapy in the history of China has released very little blood, usually only a few drops”. The fact is that the Yellow Emperor’s Classic of Internal Medicine, the foundational work of Chinese medicine, repeatedly mentions that bloodletting should be done until “the blood changes”. What do you mean by “until the blood changes”? This is what Xu Da-chun, a famous doctor in the Qing Dynasty, said: “Where there is evil in the blood, it must be removed, if the blood is shot out and black, it will change color and see red, otherwise the disease will not be removed but harm” (Medical Source and Stream). . Anyone with a little clinical experience knows that the amount of blood released by such a bloodletting method would not be just a few drops. Historically, there are still many examples of ancient Chinese who used large doses of bloodletting. For example, in the Song Dynasty, Lou Quanshan treated laryngeal paralysis by stabbing the Taixi point to produce half a jan of black blood; Chen Ziming’s “Essence of Surgery” treated gangrene of the back, acupuncture red place, bleeding bowl, and then the back heavy and suddenly removed; Zhang Congzheng, the patriarch of the Jin-Yuan period, stabbed blood in liters and in buckets, with outstanding results. Probably by the Qing Dynasty, the method of massive bloodletting was gradually used less and less, as Xu Da-chun said: “The ancients stabbed to get a lot of blood, such as headaches and lumbago, a large diarrhea of its blood; nowadays, people occasionally bleeding, fear of loss of evidence, how to get rid of the disease? ……”. Therefore, this Chinese treatment of massive bloodletting is not something that Mr. Fang supposedly learned from traditional Western medicine. Secondly, Mr. Fang did not really understand the modern knowledge of blood circulation. Mr. Fang claims that the “bad blood” in Chinese medicine is “a conjecture of the ancients who did not understand blood circulation. Blood is constantly circulating, running through the whole body about once every 20 seconds. The blood of the whole body is one, there is no difference between bad blood and good blood”. Did the ancient Chinese not know that blood is circulating? No! Of course the ancient Chinese did not discover the true way of blood circulation, but the Yellow Emperor’s Classic of Internal Medicine presents two theories of blood circulation, one is the twelve meridians of qi and blood flow, and the other is the theory of the five transfusion points where qi and blood circulate toward the heart. The Yellow Emperor’s Classic of Internal Medicine clearly states that the circulation of qi and blood is “like a ring without end”, so we cannot assume that the ancients did not know that blood circulates. It is nonsense to say that “the blood of the whole body is one”. What tissue in the whole body is not one? It is the organic connection between all parts of the body that TCM emphasizes! Mr. Fang claims that blood is constantly circulating, running through the whole body about once every 20 seconds, which is to know one thing but not the other. It is true that the blood in the main part of human body circulation can circulate once every few tens of seconds, but not all the blood components in body circulation run through the whole body once. For example, the blood flow in the capillaries is extremely slow, only 0.41 mm per second, 20 seconds can only go 8.2 mm, if the blood flow in the microcirculatory disorders is even slower; varicose veins in the blood flow is also extremely slow. If blood can run all over the body once every 20 seconds, there will be no varicose veins and many other diseases. The so-called “bad blood” in Chinese medicine refers to the blood stagnated in the veins or microvessels, because the circulation speed is slow, the oxygen content of these blood is low, and the metabolic products and harmful ingredients absorbed by food cannot be discharged out of the body quickly, so the toxic content of these blood is high, so it is called “bad blood”. What’s wrong with calling it “bad blood”? The microcirculation theory of modern medicine believes that the aging of the human body, the occurrence of tumors, hypertension, diabetes, cardiovascular and many other diseases, mainly due to microcirculation disorders. When the microcirculation is impaired, the blood flow is slow, and certain components in the blood not only thicken the blood vessel wall, but sometimes coalesce to block the blood vessels, resulting in more poor blood flow, forming a vicious circle, and the metabolism of local tissues and organs cannot be carried out normally, causing the occurrence of many diseases. There is no difference between bad blood and good blood in the human body, which is only possible when the person is healthy and free of disease, but we can often find “bad blood” somewhere when the person is in a state of disease or discomfort. What is the basis of Mr. Fang’s claim that bloodletting is a dangerous therapy? It is the one mentioned in the article that one of the physicians who had the most blood released had 850 ml of blood released. It is indeed dangerous enough to let 850ml of blood at a time, but the doctor generally “the amount of blood let varies from person to person, as little as 100-200ml and as much as 400ml”, and Mr. Fang also admitted that “donating 200-400ml of blood is harmless to the human body”. Then how is this 400 ml of blood donation harmful and dangerous? This is Mr. Fang’s way of denying the whole treatment with extreme cases. Surgical procedures for serious illnesses carry the risk of dying on the operating table, so by Mr. Fang’s logic, should surgery be considered a dangerous therapy? From this we can see that Mr. Fang is attacking Chinese medicine in every way possible, which has lost the impartial position a scholar should have. I cannot help but ask if Chinese blood still flows in Mr. Fang’s veins. Has Mr. Fang’s opinion that the efficacy of bloodletting therapy is uncertain been investigated and counted? As far as I am concerned, my patients and family members are deeply benefited by bloodletting therapy. I treat more than a hundred patients daily, and new patients have been booked until a month later, of which bloodletting therapy is one of the common methods and is highly credited. My bloodletting usually does not exceed 100 ml and is not dangerous. I don’t need to talk about the efficacy of specific diseases here, because in some people’s eyes these efficacy are by chance, but I hope that there are more doctors who can “happen” to cure diseases, so as to solve more pain for patients and divert some of the burden of too much consultation for me. It should be pointed out that bloodletting is not only a simple way to release stagnant or poisonous blood, but also a way to stimulate the walls of blood vessels, which are rich in nerves and endocrine cells in some parts, so the stimulation of blood vessels may also regulate nerves and endocrine effects. Bloodletting is not obsolete, but we need to study its specific mechanism of action. We do not “already have a safer and more reliable method”, but there is a shortage of safer and more reliable methods! Otherwise, WHO would not consider that modern medical technology can only treat 8% of diseases.
