Origin of traditional Chinese medicine prescription

Traditional Chinese Medicine (TCM) is a medicine used by TCM, which is unique to traditional medicine in China. Under the guidance of Chinese traditional medical theory, drugs collected, processed, prepared, explained the mechanism of action and guided clinical application are collectively referred to as traditional Chinese medicine. In short, traditional Chinese medicine refers to substances that are used to prevent, treat and diagnose diseases and have rehabilitation and health care functions under the guidance of traditional Chinese medicine theory. Traditional Chinese medicine is mainly composed of plant medicines (roots, stems, leaves and fruits) and animal medicines (viscera, skins, bones, organs, etc.). ) and mineral medicine. Because plant medicine accounts for most of Chinese medicine, there is a saying that "all medicines are based on grass", so Chinese medicine is also called Chinese herbal medicine. Three Kingdoms Wei's theory of health preservation: "Therefore, Shennong said that those who take medicine to nourish their lives and Chinese medicine to nourish their nature are really know life's principles, because they are supplemented." Jin Zhanghua's "Natural History" Volume 7: "Chinese medicine nourishes nature, which means that lovesickness is angry and day lilies forget their worries." Song Xuxuan's poem "Temple" said: "Chang Jie is sick, suspicious of Chinese medicine, and intends to seek truth and help each other." Traditional Chinese medicine mainly comes from natural medicines and their processed products, including plant medicines, animal medicines, mineral medicines and some chemicals and biological products. Traditional Chinese medicine is divided into Chinese patent medicine and Chinese herbal medicine according to the processing technology.

Traditional Chinese medicine is commonly known as "materia medica" in China ancient books. The earliest monograph on traditional Chinese medicine in China is Shennong Herbal Classic in Han Dynasty, which contains 365 kinds of medicines such as animals, plants and minerals, each of which contains taste, function and indications. Another orderly example briefly describes the basic theory of medication, such as toxicity, four qi and five flavors, compatibility, medication methods and dosage forms such as pills, powders, ointments and wine, which can all be used. The New Compendium of Materia Medica promulgated by the Tang government is the earliest pharmacopoeia in the world. It contains 844 kinds of drugs and is accompanied by a drug map, which is the first example of graphic comparison of Chinese herbal medicine works. It not only had a great influence on the development of pharmacology in China, but also spread abroad quickly, making an important contribution to the development of world medicine. Li Shizhen's Compendium of Materia Medica in Ming Dynasty summarized the experience of using drugs before16th century. This book contains 1892 drugs and more than 1 1000 prescriptions, which has made great contributions to the development of pharmacology in later generations.
