The concept of “liver” in Chinese and Western medicine is different, and many people think that liver care is to take care of the liver as an organ. However, in Western medicine, the liver is an anatomical unit. The liver is a human organ with the functions of detoxification, synthesis, metabolism, excretion and adjustment of blood volume, which is deeply hidden under the diaphragm in the deep right abdominal cavity. So how to protect it from damage is to protect the liver, such as preventing the transmission of hepatitis virus, reducing the damage of drugs, alcohol and fat is to protect the liver. The concept of “liver” in Chinese medicine refers to the function of the liver. The liver in Chinese medicine is not only the anatomical liver, but also a functional activity system, which is a more abstract concept, such as the mental and emotional activities of human beings, which are all related to the function of the liver in Chinese medicine. Similarly, the concept of “liver disease” in TCM is also different from the liver diseases referred to in Western medicine. The scope of liver disease in TCM is based on the dysfunction of the liver and gallbladder and the diseases caused by their meridian circulation, which is mainly a group of disease concepts. For example, certain ophthalmological diseases, neurological diseases, mental system diseases, etc. can often be seen in TCM treatment as “liver fire inflammation”, “liver and kidney yin deficiency”, “liver blood deficiency “Some patients think that their liver has problems, but this often does not belong to the scope of Western medicine liver disease. Thus, the concepts between the two should not be confused.
