Biographical Introduction and Historical Accounts

Ke Qin, a Qing dynasty scholar of Shang Han Lun (The Treatise on Cold-Induced Diseases), used the aliases Yunbo (Yùn Bó) and Sifeng (Sì Fēng); his self-chosen literary name was Sifeng. He was a native of Cixi (present-day Zhangting, Yuyao). A native of Cixi (present-day Zhangting Town, Yuyao City, Zhejiang Province), he was well-versed in classical literature and skilled in composing poetry and "ci". Having abandoned preparation for the imperial civil service examinations, he devoted himself to the study of medicine despite his family’s poverty. He traveled to the Wu region and settled in Yushan. Reserved about his medical knowledge, he remained relatively unknown during his lifetime. His approach—“naming syndromes after prescriptions and classifying syndromes according to prescriptions”—is clinically pragmatic and profoundly influenced later studies of Shang Han Lun. Little biographical detail survives; available records identify him as both a Confucian scholar and a highly competent physician. He died in Yushan in his old age.

Major Works and Academic Contributions

Ke Qin deeply studied foundational texts such as Nei Jing (The Inner Canon) and Shang Han Lun (The Treatise on Cold-Induced Diseases). Among his works are medical treatises and annotated compilations. He compiled Nei Jing He Bi (Two-Piece Jade Combination of the Inner Canon, or A Harmonized Compilation of the Inner Canon), now lost. His extant major works include Shang Han Lun Zhu Annotations on the Treatise on Cold-Induced Diseases), Shang Han Lun Yi (Supplementary Treatise on Cold-Induced Diseases), and Shang Han Fu Yi (Additions to the Treatise on Cold-Induced Diseases). These three were later collected and published together as Shang Han Lai Su Ji (Renewal of the Treatise on Cold-Induced Diseases), widely regarded as a seminal model for studying Shang Han Lun.

Unlike many contemporaries, Ke Qin did not prioritize textual emendation or philological reconstruction of Zhang Zhongjing’s original text. Instead, he focused on elucidating the core principles of syndrome differentiation ("bian zheng") and treatment ("lun zhi"). As he stated: "Zhang Zhongjing’s six-channel system establishes a universal principle applicable to hundreds of diseases—not merely Shang Han (cold-induced diseases); . Cold-induced diseases and miscellaneous diseases alike are governed by the same six-channel framework; each channel manifests cold-induced disease, but cold-induced disease is not confined to the six channels ("liu jing") alone." Accordingly, he reorganized the text by channel, classified categories according to syndromes, and grouped prescriptions under corresponding syndromes—thereby integrating cold-induced and miscellaneous diseases under the six-channel paradigm. This method rendered syndrome differentiation and treatment more practical, systematic, and lucid. His theoretical annotations are clear, logically ordered, and reflect original insights—particularly in the classification of miscellaneous diseases, which follows Wang Haogu’s precedent. The work exerted a marked influence on later generations. In each of the six-channel chapters, he first outlines principal syndrome categories, then lists relevant syndromes and prescriptions within each category—including deteriorated cases, mistreated cases, and diagnostic dilemmas.

This method of textual organization is more clinically pragmatic. Inspired by it, later generations of physicians classified syndromes according to therapeutic methods and categorized them by symptom patterns to explore the principles of syndrome differentiation ("bian zheng") and treatment ("lun zhi") in Shang Han Lun (The Treatise on Cold-Induced Diseases) from multiple perspectives. At the same time, Ke Qin rejected the prevailing Tang–Song view that Shang Han Lun was solely a monograph on exogenous febrile diseases. He argued that the six-channel system applies equally to miscellaneous diseases. He also examined the fundamental nature of the six channels, summarizing them as “the foundational theory of the six-channel meridian system,” and provided detailed explanations.

Shang Han Lun Zhu (Annotations on the Treatise on Cold-Induced Diseases) is a four-volume work by Ke Qin, completed in 1669 CE. In composing and annotating this text, Ke Qin integrated his core thesis: "Zhang Zhongjing’s six-channel principle governs all diseases—not merely Shang Han (cold-induced diseases)." He systematically revised and annotated Shang Han Lun entry by entry and sentence by sentence. Its distinctive organizational feature is syndrome-centered classification—for example, Ma Huang Tang syndrome, Gui Zhi Tang (White Tiger Decoction) syndromes, Bai Hu Tang (Cinnamon Twig Decoction) syndrome, and Cheng Qi Tang syndrome, among others. Each syndrome group consolidates related passages under a unified clinical heading. Thanks to Ke Qin’s lucid explanations and integrative annotations, this edition presents a clear, coherent, and substantively enriched arrangement; his personal insights are seamlessly interwoven with classical exposition. His work profoundly influenced subsequent commentaries on Shang Han Lun.

Shang Han Lun Yi (Supplementary Treatise on Cold-Induced Diseases) is a two-volume work completed in 1674 CE. Ke Qin critically engaged with earlier Tang–Song editors’ approaches to collation, textual emendation, and reconstruction of Shang Han Lun. He maintained: "Shang Han (cold-induced diseases) and miscellaneous diseases are governed by a single theoretical framework—the six-channel system. Each channel manifests cold-induced disease, yet cold-induced disease is not confined to the six channels alone." Accordingly, Volume I addresses major topics—including cold-induced disease methodology, the six channels, combined syndromes, wind-cold syndrome, warm and heat, warm disease and summer heat, convulsive disorders, dampness diseases—as well as normal pulse patterns and pulse diagnosis. Volume II systematically outlines the six-channel syndromes. Major prescription methodologies conclude the volume, making it an essential supplementary study guide to Shang Han Lun.

Shang Han Fu Yi (Additions to the Treatise on Cold-Induced Diseases) comprises two volumes devoted exclusively to the prescriptions of Shang Han Lun. It elucidates the indications, mechanisms of action, and clinical applications of each formula by integrating etiology, pathogenesis, and pulse–syndrome correlations. It serves as a valuable reference for studying the pharmacotherapeutic foundations of Shang Han Lun.
