According to the clinical symptoms, benign thyroid swellings belong to the category of “gall disease” in Chinese medicine. For example, in the “Three Causes and One Disease Formula? Gall tumor evidence and treatment”: “hard and immovable, called stone gall; skin color unchanging, called flesh gall; tendon veins nodules, called tendon gall; red veins interlocking, called blood gall; years of worry and sorrow to eliminate, called gas gall”. The “Essays on Reading Medicine” once said, “A doctor who is good at regulating the liver is good at curing all diseases.” The close relationship between benign thyroid swellings and the liver is due to the fact that the orderly rise and fall of qi in the organism and the normal operation and distribution of qi, blood, and fluids are subject to the drainage function of the liver. For example, “Blood evidence theory? Viscera pathogenesis” cloud: “the nature of the wood is concerned with the sparing …… liver is wood, wood qi rushing and striped, not to curb the depression of the heart veins to be smooth.” In Chinese medicine, the so-called “liver is the main drainage” means that the liver has the physiological effect of regulating emotions, smooth qi, and help the spleen to transport. If depression, anger and injury to the liver, or evil in the liver meridian can affect the draining function of the liver, causing pathological changes such as qi stagnation, phlegm blockage, dampness, qi deficiency, blood stasis, etc. and the disease becomes “gall disease”. As stated in the treatise on Gall Tumors Gall tumor theory” said: “The symptoms of the lady’s gall tumor, not Yin and Yang positive Qi swelling, is the five viscera blood stasis, turbid Qi, phlegm stagnation. And “Taiping Shenghui Fang” recorded: “The initial onset of gall is caused by a person’s anguish and rage against the Qi, which is stored.” This indicates that emotional and mental abnormalities are a common cause of gall disease. According to the Golden Guide to Medicine, the Liver Meridian of the Foot: “Goes up through the diaphragm, spreads to the ribs, disperses to the internal organs, follows the throat, goes up into the fly down, connects to the eye system, goes up to the forehead and meets the Governor’s Vessel in the upside down.” This explains that where the Liver meridian travels, it is precisely where the “gall disease” is located. Therefore, the treatment of benign thyroid swellings from the liver has important clinical significance. Ye Tianshi once said, “Diseases have testimonies, changes, and transitions, so one must see the initial and final transmissions and have a good idea of what to do before applying the prescription.” This shows that the key to the treatment of the disease is to prevent the slightest change and cut off the disease. Although thyroid nodules are mostly blamed on the liver, in terms of the pattern of disease transmission, they can also involve the spleen and stomach and evolve into evidence of liver depression and spleen deficiency. As stated in the chapter on hypochondriac pain, “If the disease is prolonged, it must affect the Yangming stomach lobe and gradually return to the right side, so the liver and stomach are sick together.” Traditional medicine says that the spleen is the “essence of the later heaven” and resides in the middle jiao, which is responsible for transporting, clearing and regulating blood. The spleen and the stomach belong to the same earth, which is the main organ of the central state and irrigates the four sides. The strength of the spleen and the stomach and the order of the ascending and descending of the spleen also depend on the proper drainage of the liver. If the emotions are not comfortable, the liver is depressed, the liver is depressed and the spleen is overcome, the spleen and stomach will eventually be damaged and the phlegm and dampness will be generated internally. Phlegm and dampness stay and do not transform, obstructing the qi, but also can be injured in the internal organs to make its dysfunction, by giving rise to qi stagnation, stasis of blood. Phlegm, stagnant blood, and stagnant qi are congested in the front of the neck, which is the problem of “gall disease. Therefore, Wu Qianji writes in the “Golden Guide to Medicine” that “the spleen is the master of the muscles, depression and injury to the spleen, the muscles are shallow, the earth does not work, and the reverse is in the flesh, resulting in flesh galls”. It is clear that the liver and spleen are inextricably linked to the development of galls in the body. In today’s society, with the accelerated pace of life, increased work pressure and the stimulation of various negative social life events, the mental and psychological stress of human beings is gradually increasing, which is followed by an increase in various psychiatric and endocrine disorders. The key to treating benign thyroid nodules from the liver and spleen is to “relieve liver depression and strengthen the spleen and stomach”. Only when the liver is properly drained and the spleen is strong and healthy in transporting and transforming, there will be no gas stagnation, phlegm and blood stasis. It is true that as stated in the book “The Authentic Principles of Surgery”, “like scrofula, phlegm injection, gas puffiness, gall tumor, the treatment does not need to be published and attacked, but should only nourish blood, regulate the meridians, strengthen the spleen, harmonize the middle, move phlegm and open the depression, the method is the best”. The treatise on the spleen and stomach also says: “The only good treatment for this disease is to harmonize the spleen and stomach.” It can be seen that the treatment of benign thyroid swellings should be based on “regulating the liver and spleen first and mediating the qi flow”.
