The Jing ethnic group is distributed in coastal and border areas of China, and after thousands of years of development, it has formed a rich marine-oriented medical system in the struggle against the environment and diseases, displaying unique medication characteristics and clinical efficacy. According to Jing Medicine, the human body is an organic whole that is unified with the natural and social environment. It believes that the heavens and earth are the spirits of all things, and all things possess spiritual energy, which is closely connected to the human body’s spiritual energy. The utilization of marine organisms in medicine is the greatest feature of Jing Medicine, and it is a common approach used by the local population for disease prevention and treatment. To further explore Jing Medicine, improve the repository of ethnic medicine culture, and address the insufficient understanding of Jing Medicine in traditional Chinese medicine culture, this article provides a comprehensive review of the distinctive diagnostic and therapeutic theories, techniques, and applications of internal and external treatments in Jing Medicine.展开更多

It is a medicine developed by ethnic minorities in order to survive and reproduce and in the process of fighting diseases. Culture, based on its own language, life experience and cultural traditions, has its own understanding and theoretical system of disease naming, etiology and pathogenesis, treatment principles and treatment methods, which is a major feature of my country’s medical care. Among them, ethnic medicine has unique advantages and good clinical efficacy in the prevention and treatment of cholelithiasis. Therefore, this paper focuses on summarizing the characteristic theories and diagnosis and treatment experience of Tibetan medicine, Mongolian medicine, Miao medicine, Yao medicine, and Beijing medicine in ethnic medicine by sorting out and summarizing the relevant materials in this regard, so as to provide new ideas for improving the treatment of cholelithiasis and enriching clinical drug selection.展开更多
