许叔微

Xu Shuwei is an important physician in the history of traditional Chinese medicine. Publicly available sources offer limited information about his life, and neither his dates nor his native place are known with certainty, yet his surviving works attest to considerable medical expertise. Seven of his works are held in the collection, including the Puji Benshi Fang, its classified sequel, the Shanghan Fawei Lun, the Shanghan Jiushi Lun, the Benshi Fang Xuji, the Puji Benshi Fang Xuji, and the Shanghan Baizheng Ge. These writings span both formulary compilations and analyses of cold-damage theory, combining practical prescriptions organized by pattern with mnemonic verses suited to study and recitation. His style is orderly and clinically practical, touching on Eastern philosophy and culture as well as medicine, and his work has exercised a lasting influence on later developments in Chinese formulary and cold-damage scholarship.
