1 "Difficult Classics". "Difficult Classics" was originally named "The Yellow Emperor's Eighty-one Difficult Classics", with a total of three volumes * *, originally published by Qin Yueren. Difficult Classics is a classic work of Chinese medicine theory. Difficulties include "asking difficult questions" or making difficult explanations. Classic refers to Neijing, which means "asking difficult questions". This book puts forward the difficulties and doubts in Neijing, and then explains them one by one, giving full play to some problems. The book is divided into eighty-one difficult points, and many problems such as the functional form of human viscera, pulse diagnosis and acupuncture of meridians are discussed one by one. The contents include pulse diagnosis, meridians, viscera, yin and yang, etiology, pathology, camp and health, acupoints, acupuncture and other basic theories, and also lists some diseases and syndromes. The book is based on basic theory, combined with some clinical medicine. The basic theory is based on pulse diagnosis, viscera, meridians and Shu points. Among them, it is difficult to discuss pulse condition, meridians, viscera, diseases, acupoints and acupuncture from 23 to 29, 30 to 47, 48 to 6 1, 62 to 68, 69 to 8 1 respectively. The academic views on Mingmen and Sanjiao in the book, as well as the names of Qichongmen and Bahui, enrich and develop the theoretical system of traditional Chinese medicine. In addition, the book clearly puts forward that "there are five kinds of typhoid fever", and expounds many diseases such as five zang-organs diseases and diarrhea, which has had a certain influence on the development of typhoid fever theory and febrile disease theory in later generations and is considered as one of the most important classic medical books.
(2) Treatise on Febrile Diseases. At the end of the Eastern Han Dynasty, Zhang Zhongjing, a native of Nanyang, wrote Treatise on Febrile Diseases in 200-205 AD. Later generations compiled the contents of exogenous fever into Treatise on Febrile Diseases, which is a monograph on treating exogenous diseases and their miscellaneous diseases. Treatise on Febrile Diseases focuses on a series of pathological changes caused by human body feeling the evil of wind-cold and how to treat it according to syndrome differentiation. He divided the symptoms into six types: sun, Yangming, shaoyang, Taiyin, Jueyin and Shaoyin, which were called "Six Classics". According to the strength of human body's disease resistance, the severity of illness and other factors, various symptoms in the evolution of exogenous diseases, such as symptom characteristics, lesion site, visceral injury, cold and heat tendency, and the rise and fall of pathogenic factors, are summarized as the basis for diagnosis and treatment. This book summarizes the medical achievements and rich practical experience of predecessors, integrates the medical achievements before the Han Dynasty, and systematically expounds the syndrome differentiation and treatment of various exogenous diseases in combination with its own clinical experience. It is of epoch-making significance in the history of the development of traditional Chinese medicine, plays a role of connecting the past with the future and has made important contributions to the development of traditional Chinese medicine. Specifically, he not only put forward the dialectical program and treatment methods of exogenous diseases, but also provided the norms of syndrome differentiation and treatment for clinical departments of traditional Chinese medicine, laid the foundation for syndrome differentiation and treatment, and was regarded as a classic by later physicians.
(3) Shennong Herbal Classic. Shennong's Classic of Materia Medica, also referred to as Shennong's Classic of Materia Medica, was written in the name of Shennong. Shennong's Classic of Materia Medica is the earliest existing monograph on pharmacology in China, the first systematic summary of early clinical medication experience in China, and it has been praised as a classic of traditional Chinese medicine in past dynasties. Shennong Herbal Classic is divided into three volumes and contains 365 kinds of medicines, including 252 kinds of plant medicines, 67 kinds of animal medicines and 46 kinds of mineral medicines. In the book, the essence of TCM theory is expounded in simple words, and the source, nature, collection time, medicinal parts and indications of each drug are recorded in detail. Summarized how various drugs and simple preparations cooperate with each other in application. Shennong's Classic of Materia Medica also describes the nature and taste of drugs in detail: it points out that four flavors of cold, heat and cold and five flavors of acid, bitter, sweet, pungent and salty are the basic temperament of drugs, and drugs can be selected according to the different properties of diseases such as cold, heat, dampness and dryness. Choose hot drugs for cold diseases; Choose cold medicine to treat fever; Wet disease with warm and dry products; Dry diseases must be cool and moist. In addition, referring to the relationship between the five elements and the generation of grams, we have a good understanding of the meridian tropism, trend, fluctuation and ups and downs of drugs, so as to achieve twice the result with half the effort. The principle of "seven emotions and harmony" put forward by Shennong's Herbal Classic has played a great role in the practice of medication for thousands of years.
What needs to be spent is that at present, the academic circles generally regard Difficult Classics, Treatise on Febrile Diseases, Shennong Herbal Classics and Huangdi Neijing as the four classics of Chinese medicine, and there is no so-called "three medical books". It's just that Huangdi Neijing focuses on "prevention before illness", and some people can make it a book of health preservation. In fact, Huangdi Neijing is the first classic of TCM theory.
