Biographical Introduction and Historical Accounts

  Zhang Lu—whose alias was 路玉 (Lù Yù)—was born around 1617 and died in 1699 CE. He lived from the late Ming to the early Qing dynasty. In his old age, he adopted the self-designation "Stone-Mad Old Man" (石頑老人, Shí Wán Lǎo Rén). He was a native of Changzhou—now part of modern-day Changzhou City, Jiangsu Province—in Jiangnan (south of the Yangtze River). He was the grandson of Zhang Shaofeng (張少峰, Zhāng Shàofēng), an imperial inspector (censor) of the Ming dynasty. From childhood, Zhang Lu displayed exceptional intelligence and receptivity. He initially studied Confucian classics and medicine. After the fall of the Ming dynasty, he abandoned the civil service examination path and devoted himself entirely to medicine. He resided on Dongting Mountain for over a decade, practicing medicine, writing treatises, and working tirelessly into old age. Sixteen years after leaving his hometown, he returned bearing numerous medical manuscripts he had compiled. His sons, Zhang Deng (張登, Zhāng Dēng) and Zhang Zhuo (張倬, Zhāng Zhuō), also pursued medicine and authored related works.

Major Works and Academic Contributions

 Zhang Lu devoted his life to academia and medicine, particularly the study of the Shanghan Lun (Treatise on Cold-Induced Diseases). After accumulating insights over three decades, he compiled the seminal works Shang Han Zuan Lun and Shang Han Xu Lun. His other major works include: Zhen Zong San Mei (The Three Essential Principles of Diagnosis), 1 volume (1680 CE), focusing on pulse diagnosis; Qian Jin Fang Yan Yi (Elucidation of the Thousand Gold Prescriptions), 30 volumes, a detailed commentary on prescriptions from Sun Simiao’s Qian Jin Yao Fang (The Invaluable Prescriptions), herbal work Ben Jing Feng Yuan (Origins and Applications of the Materia Medica Canon), 4 volumes (1695 CE), expounding on herbal properties and clinical applications; and Zhang Shi Yi Tong (Comprehensive Medical Compendium of the Zhang Family), a systematic, encyclopedic medical treatise.

 In his study of exogenous febrile diseases, Zhang Lu held that Shanghan (exogenous febrile diseases) and miscellaneous diseases were both distinct and interrelated. His interpretation of Shanghan centered on the conceptual framework of “Yin-Yang Chuan Zhong” (Yin and Yang Transmission to the Middle), which he elaborated in depth. He systematically summarized the patterns of Yin-Yang channel transmission, direct invasion, syndrome differentiation, identification and analysis of the six channels, Zang and Fu viscera, and cold and heat of the exterior and interior. Regarding the six-channel syndromes described in the Shang Han Lun, Zhang Lu proposed that at the onset of Taiyang disease, three principal syndromes could be distinguished: Feng Shang Wei (wind pathogen attack and hurt the Wei system), Han Shang Ying (cold pathogen attack and hurt the Ying system), and Feng Han Shang Ying Wei (simultaneous wind and cold attacking and imparing the Ying and Wei systems). Correspondingly, he prescribed Gui Zhi Tang, Ma Huang Tang, and Qing Long Tang, respectively. Furthermore, Zhang Lu argued that the three-Yin cold syndromes were all related to Shaoyin, and the three-Yin cold syndromes should center on Shaoyin—what he termed “treating the root cause” (i.e., addressing the primary pathological basis).

 Zhang Lu’s scholarship on exogenous febrile diseases also emphasized differential diagnosis of warm diseases and incorporated tongue diagnosis into syndrome differentiation and treatment—a contribution that significantly influenced the later development of the Warm Disease School (the systematic study of epidemic febrile disorders in traditional Chinese medicine). In treating miscellaneous diseases, he prioritized precise syndrome differentiation and excelled in warming and tonifying therapies, establishing himself as a leading representative of the Warming-Tonifying School during the Ming and Qing dynasties. His profound academic influence earned him recognition as one of the three great physicians of the early Qing dynasty.

 Shang Han Zuan Lun (Inherited Discussions on the Treatise on Cold-Induced Diseases) is a two-volume annotated commentary on the Shang Han Lun, authored by Zhang Lu during the Qing dynasty and first published in the sixth year of the Kangxi reign (1667 CE). Dissatisfied with the divergent interpretations of earlier commentators—whom he observed as “differing without convergence”—Zhang Lu undertook extensive research. He studied key prior works, including Shang Han Lun Tiao Bian by the Ming-dynasty physician Fang Youzhi and Shang Lun Pian by the early-Qing scholar Yu Chang. After consulting numerous sources and engaging in rigorous, repeated analysis, he concluded that “the seemingly divergent views would gradually converge.” Drawing upon thirty years of dedicated study of the Shang Han Lun, he produced his authoritative annotation and interpretation of Zhang Zhongjing’s classic—resulting in the Shang Han Zuan Lun. Structured according to Yu Chang’s edition, the work integrates annotations from multiple schools while incorporating Zhang Lu’s own insights. Volume I systematically addresses diseases and syndromes of the six channels; Volume II covers specialized topics—including Zang Jie (accumulation of yin cold in the viscera), Xiong Pi (distention and fullness in the chest), He Bing Bing (disease involving two or more channels, combined syndrome, overlapping of syndromes), Wen Re Jing Shi Ye (warm disease, febrile disease, convulsion, dampness disease, summer-heat disorders).

 Shang Han Xu Lun (Continued Discussions on the Treatise on Cold-Induced Diseases), compiled by Zhang Lu, is a two-volume annotated commentary on the Shang Han Lun (Treatise on Cold-Induced Diseases). Zhang Lu established its structural framework, and his sons Zhang Deng and Zhang Zhuo assisted in revision. The book was first published in the sixth year of the Kangxi reign of the Qing dynasty (1667 CE). It addresses the incomplete parts in the original Shang Han Lun, particularly gaps in syndrome description, therapeutic principles, and prescription formulation. Drawing upon interpretations from multiple scholarly traditions, it offers systematic differentiation and analysis of syndromes and treatments. As stated in its preface: "To clarify distinctions among the various schools, outline their frameworks, supplement Zhang Zhongjing’s methods, and elucidate their origins and sources." Zhang Lu aimed to "remove all obstructions to Zhang Zhongjing’s method," thereby enhancing accessibility and practical utility for learners and clinicians. However, the supplementary prescriptions included in this work suffer from shortcomings—including insufficient compatibility among constituent herbs and lack of formulaic purity.

 Zhang Shi Yi Tong (Comprehensive Medical Compendium of the Zhang Family) authored by Zhang Lu and published in 1695 CE (the thirty-fourth year of the Kangxi reign), is a sixteen-volume encyclopedic medical treatise focused primarily on miscellaneous diseases. It epitomizes Zhang Lu’s mature academic thought and stands as his most influential medical work. According to the author’s preface, compilation began in the Jia Shen year (1644 CE); the first draft was completed in the Ji Hai year (1659 CE) and originally titled Yi Gui. However, due to the scattering and loss of portions of the manuscript, Zhang Lu undertook extensive supplementary revisions over many years. He consulted nearly 130 medical texts from previous dynasties and solicited feedback from more than 40 contemporary physicians—including You Cheng (尤乘, Yóu Chéng) and Li Yongcui (李用粹, Lǐ Yòngcuì). This process spanned five decades; the manuscript underwent ten major revisions, underscoring the extraordinary effort invested in its creation. The diagnostic categories and organizational structure of Zhang Shi Yi Tong largely follow Wang Kentang’s Zheng Zhi Zhun Sheng (Standards of Diagnosis and Treatment), , dividing content into sections on internal medicine, external medicine (surgery), gynecology, pediatrics, and disorders of the five senses—each accompanied by verified clinical cases. Volumes 1–7 cover internal medicine; Volume 8, otolaryngology and ophthalmology(department of ear, nose, throat, or ENT); Volume 9, surgery; Volumes 10–11, gynecology; Volume 12, pediatrics, and Volumes 13–16, prescriptions. The main prescriptions have reference to Xue Ji's medical case records and Zhang Jiebin's Jing Yue Quan Shu (Jing Yue's Complete Works), synthesizing classical medical theory and empirical knowledge with Zhang Lu’s own clinical experience to refine and elaborate therapeutic approaches. The book collects prescriptions for diseases, each prescription is accompanied by detailed indications, rationale, and explanations of herb compatibility. Rich in content and rigorously organized, the work achieved wide circulation upon publication. Scholars of his epoch lauded it as “a truly authoritative medical text.”

 Zhen Zong San Mei (The Three Essential Principles of Diagnosis), a one-volume work compiled by Zhang Lu of the Qing dynasty and edited by his son Zhang Deng, was first published in the twenty-eighth year of the Kangxi reign (1689 CE). Zhang Lu held that all diseases manifest discernibly in the pulse; simultaneously, he critiqued prevailing pulse studies of his time, declaring: "I shall employ the ‘Three Concealed Waters’ to cleanse away the dust”—a metaphorical expression reflecting his aim to restore clarity and depth to pulse diagnosis. Hence, this treatise was composed.

 Ben Jing Feng Yuan was compiled by Zhang Lu and completed in the 34th year of the Kangxi era (1695 CE). It is divided into four volumes and describes more than 700 kinds of herbs. It is the only pharmacological work among Zhang Lu’s many books, focusing on the clinical applications of herbs. This book is a masterpiece with unique insights that render it lucid and further stimulate critical thinking upon reading. Recognizing that the Sheng Nong Ben Cao Jing (Shen Nong’s Materia Medica) recorded only a few herbs—some of which are lost or have limited clinical utility—and that it contains no detailed records of commonly used herbs, Zhang Lu used the Sheng Nong Ben Cao Jing as a basis and the classification method of the Ben Cao Gang Mu (the Compendium of Materia Medica) as a reference. He listed more than 700 commonly used herbs in 32 categories across four volumes and published the book. Although this book’s name is based on the Ben Jing (Shen Nong Ben Cao Jing, or Shen Nong’s Materia Medica), it does not focus on textual collation. In fact, it focuses on the clinical application of herbs. After repeated consideration, Zhang Lu selected more practical herbs closely related to clinical practice. He compiled this book at the age of seventy-nine. It is a masterpiece reflecting his sixty years of experience in practicing herbal medicine. It not only embodies his lifelong painstaking efforts in herbal research but also records many of his unique insights.

 Shang Han Jian Zheng Xi Yi is a one-volume book compiled by Zhang Zhuo, the son of Zhang Lu. The book was published in the sixth year of the Kangxi era (1667 CE). It is said that “medicating is difficult, and Shang Han—the study of cold-induced disease and exogenous febrile diseases—is the most difficult, especially for patients with concurrent miscellaneous diseases.” Moreover, for combined or overlapping syndromes in Shang Han, only the accompanying symptoms of the six channels were discussed; miscellaneous diseases were not addressed. Therefore, the book categorizes seventeen miscellaneous diseases—including Zhong Feng (apoplexy) and consumptive disease—and employs a question-and-answer format to analyze them. Finally, it includes appended discussions on the twelve meridians, the eight extra meridians, the Yun Qi theory (the doctrine of the five evolutive phases and six climatic factors), as well as the origins of prescriptions—topics that were quite innovative at the time.
