柯琴

Ke Qin's biographical details are limited in publicly available sources; his dates of birth and death, nationality, and similar information are not clearly recorded. Judging from the works that survive, he was a medical author devoted to the study of the Treatise on Cold Damage (Shanghan Lun). Six of his works are held in the collection, including Annotated Treatise on Cold Damage, Collected Works on Cold Damage Laizhu, Supplementary Wings to Cold Damage, and Wings of the Cold Damage Treatise, as well as a guided-reading edition of Collected Works on Cold Damage Laizhu and an unannotated edition of Annotated Treatise on Cold Damage. These works revolve around Zhang Zhongjing's Treatise on Cold Damage, covering textual annotation, analysis of formulas and syndromes, and theoretical elaboration, and belong to the traditional literature of Cold Damage studies in Chinese medicine. His writing centers on annotating the classics and expounding medical theory, with a practical style that emphasizes clarity and pattern differentiation, and has exerted a certain influence within the Cold Damage school. His works are commonly classified under medicine and Eastern philosophy, reflecting a content that touches on both medical theory and classical philosophical thinking.
