This book was written by Zhang Gao (also known as Ji Ming) of the Southern Song Dynasty. Gao was from Xin'an (near present-day She County, Anhui). The initial draft of the book was completed in the 16th year of the Chunxi era (1189). It was finalized in Gao's later years and first published in the 17th year of the Jiading era (1224), comprising 10 volumes divided into 49 sections. The first volume discusses over 120 renowned physicians before the Song Dynasty, followed by accounts of ancient medical texts, materia medica, the origins of acupuncture and moxibustion, as well as legendary healers, miraculous prescriptions, and diagnostic methods recorded in historical texts, presented in a narrative style that broadens knowledge. Subsequently, it discusses various diseases and conditions, including cold-damage disease, various wind disorders, pulmonary tuberculosis, hematemesis, recurrent headaches, eye diseases, oral and dental issues, throat and tongue disorders, ear problems, bone obstructions, asthma, and coughs, among others, covering internal, external, gynecological, and pediatric cases, offering valuable clinical references. Additionally, it includes discussions on poisoning, detoxification, rare diseases, dietary contraindications, medicinal diets, drug contraindications, health preservation, and warnings against the use of mineral-based medicines, preserving many insights from scholars and physicians of the time. The book also emphasizes the importance of medical ethics, though it is marred by superstitious beliefs such as "karmic retribution for medical deeds."
