Yu Zhaoyuan, whose given name was Zhàoyuán (肇源) and style name Gēnchū (根初), was a physician of the Qing dynasty, born around 1734 and deceased around 1799. Born in Taoli, Shaoxing, he was locally known as “Teacher Yu San” (Master Yu the Third), as he was the third son among his brothers. He came from a multi-generational family of physicians. From an early age, he inherited his family’s medical learning, studied classical and contemporary medical texts, synthesized insights from various schools, and mastered Zhang Zhongjing’s doctrine with depth and precision—producing original elaborations thereon.
Major Works and Academic Contributions
Yu Zhaoyuan left relatively few independent works, but his clinical experience and theoretical reflections were compiled under the title Tong Su Shang Han Lun (The Popular Treatise on Cold-Induced Diseases). This text was first collated and edited by He Xiushan (Hé Xiùshān) of the same region; later revised by the physician He Lianchen (Hé Liánchén) and published in the 1916 Shaoxing Medical Journal, edited by Qiu Jisheng (Qiū Jìshēng). Subsequently, it underwent successive revisions and expansions by generations of physicians—including Cao Bingzhang (Cáo Bǐngzhāng), Xu Rongzhai (Xú Róngzhāi), and others—enriching its content and clarifying its theoretical framework.
Tong Su Shang Han Lun (The Popular Treatise on Cold-Induced Diseases) is a twelve-volume monograph on cold-induced diseases, originally compiled by Yu Zhaoyuan during the Qing dynasty. Integrating classical sources with extensive personal clinical experience, the work offers a systematic exposition of pathogenesis, syndrome differentiation, pulse diagnosis, and treatment principles for cold-induced and seasonal febrile disorders. It stands as a representative synthesis of Yu Zhaoyuan’s academic thought and therapeutic practice. He emphasized that wind invasion, cold invasion, damp-warm syndromes, and warm-heat syndromes are distinct entities—yet all fall within the broader category of Shang Han (exogenous febrile diseases). The treatise centers on cold-induced diseases while comprehensively addressing etiologies, syndromes, symptoms, pulses, and treatments across the spectrum of exogenous febrile illnesses. Its therapeutic approach draws upon classical foundations without rigid adherence to ancient formulas—flexible yet precise, informative yet credible, and eminently practical. Later scholars praised it as "a masterpiece bridging past and present, adapting classical wisdom to contemporary needs with remarkable flexibility" and "the most comprehensive clinical guide to diagnosing and treating seasonal febrile diseases."
