Brief Introduction Chinese Name: 韓祗和 (Hán Zhīhé) Alias: Unknown Popular name: 韓祗和 (Hán Zhīhé) English Name: Han Zhihe (family name first) or Zhihe Han (given name first) Hometown: Xingjun or Cijun (modern-day border region of Hebei and Henan provinces) Dates: c. 1030–1100 CE Main works: 《傷寒微旨論》(Shang Han Wei Zhi Lun, or the Subtle Treatises on Exogenous Febrile Disease), completed in 1086 CE Representative works: Shang Han Wei Zhi Lun (the Subtle Treatises on Exogenous Febrile Disease). Biographical introduction and historical accounts
Han Zhihe, whose exact years of birth and death remain unknown, was a renowned physician of the Northern Song dynasty, active approximately between 1030 and 1100 CE. He devoted decades to an in-depth and rigorous study of the Shanghan theory (the theory of exogenous febrile disease). He highly valued the essential principles and core insights of Zhang Zhongjing’s Shang Han Lun (Treatise on Cold-Induced Diseases), and applied them with remarkable flexibility and contextual sensitivity. He developed innovative approaches to pulse diagnosis and treatment modalities—including diaphoresis, purgation, and warming—for Shanghan (exogenous febrile disease). Furthermore, he compiled the two-volume work Shang Han Wei Zhi Lun (Subtle Treatises on Exogenous Febrile Disease). Completed in 1086 CE, this text systematically analyzed the theories of syndrome differentiation and herbal prescription in Zhang Zhongjing’s Shang Han Lun. The original text is lost, but a reconstructed version survives—compiled from quotations preserved in the Yongle Dadian (Yongle Encyclopedia). Later generations of physicians widely praised this work. According to the records of Shang Han Wei Zhi Lun (The Subtle Treatises on Exogenous Febrile Disease), Han Zhihe served in administrative or medical posts in "two counties, Xing Jun and Ci Jun", and "two counties, Huai Jun and Wei Jun," and "Fuyang Jun"—suggesting that his family originated from the border area of present-day Hebei and Henan provinces.
Major works and academic contributions
Han Zhihe’s scholarship on exogenous febrile diseases (cold-induced diseases) was exceptionally profound. He studied Zhang Zhongjing’s Shang Han Lun (The Treatise on Cold-Induced Diseases) for over thirty years, mastering its theoretical foundations and clinical logic. He thoroughly investigated the Shang Han theory and deeply respected its essential principles and pivotal insights. His application of the theory was both flexible and clinically astute, and he introduced original contributions to pulse diagnosis and therapeutic strategies—including diaphoresis, purgation, and warming—for Shanghan. Through these innovations, he advanced and enriched Zhang Zhongjing’s legacy. In 1086 CE, he completed the two-volume Shang Han Wei Zhi Lun (The Subtle Treatises on Exogenous Febrile Disease), comprising over 20,000 Chinese characters, dedicated to clarifying, differentiating, and analyzing the syndrome differentiation and pharmacotherapeutic principles of the Shang Han Lun. Notably, Han advocated “cool-pungent diaphoresis”—a method of resolving exterior syndromes using herbs that are pungent in flavor and cool in nature. This approach helped correct the then-common tendency to overuse warm-natured herbs for exogenous febrile conditions and played a foundational role in the later development of Wen Bing (the science of epidemic febrile disease) theory in traditional Chinese medicine.
The two-volume work Shang Han Wei Zhi Lun (The Subtle Treatises on Exogenous Febrile Disease) is a specialized treatise on the Shanghan theory (the theory of exogenous febrile disease). It was compiled in 1086 CE by Han Zhihe, a physician of the Northern Song dynasty. The original manuscript has not survived; later extant versions are reconstructed editions derived from quotations preserved in the Yongle Dadian (Yongle Encyclopedia). The text comprises fifteen chapters, covering topics ranging from the etiology and pathogenesis of Shanghan to Lao Fu (relapse triggered by overexertion). It discusses pulse diagnosis and therapeutic modalities—including diaphoresis, purgation, and warming—and addresses herbal formulation, the management of specific diseases and syndromes, and includes both prescriptions and documented clinical cases. These prescriptions are not limited to those recorded in Zhang Zhongjing’s Shang Han Lun; many are original formulations by Han Zhihe himself. The various methods of diaphoresis, purgation, and warming are determined by the three stages corresponding to the solar terms: (1) after Lichun (Beginning of Spring) and before Qingming (Pure Brightness); (2) after Qingming and before Mangzhong (Grain in Ear); and (3) after Mangzhong and before Liqiu (Beginning of Autumn). Han Zhihe innovates in his interpretation of the Shang Han Lun, reflecting a certain degree of change and development. His work was important for later generations. However, the later herbalist Wang Lu (王履,Wáng Lǚ) criticized Han for "using the Wenshu syndrome as the framework for a treatise on cold-induced diseases" in his book Yi Jing Su Hui Ji (A Collection for Tracing Back the Medical Classics), a point that warrants attention. The extant version of the Shang Han Wei Zhi Lun (Subtle Treatises on Cold-Induced Diseases) is an engraved and lithographed edition from the late Qing dynasty; one copy was included in the Si Ku Quan Shu (Complete Library of the Four Treasuries), among other collections.
