Main books and academic thoughts:


 Han Zhihe's study on the exogenous febrile disease(Shang Han) is in-depth. He has studied Zhongjing's book Shang Han Lun(the Treatise on Cold-induced Diseases) for more than 30 years. He has studied the theory of Shang Han(the theory on exogenous febrile disease) in fine details, and respected the essence and key points of Zhang Zhongjing's theory. His applications are flexible, and has innovative theory on the pulse identification of Shang Han and the treatment methods of diaphoresis, purgation, and warming. He carried forward the theory of Zhang Zhongjing with his own innovations. In the year 1086 AD, he finished the book wrote Shang Han Wei Zhi Lun(the Subtle Meanings of Shang Han) in 2 volumes, with more than 20,000 characters, to differentiate and analyze the theory of syndrome differentiation and medication of the book Shang Han Lun(the Treatise on Cold-induced Diseases). Han advocated cold-pungent diaphoresis(relieving the exterior syndrome with herbs pungent in flavor and cool in property), and the prescriptions mostly used Chai Hu(Bupleurum chinense), Bo He(Herba Menthae), Shi Gao(Gypsum), Zhimu(Rhizoma anemarrhenae) and other herbs pungent in flavor and cool in property. This not only helped correct mistakes for herbalists customed to use warm herbs for exogenous diseases at the time, but also played an important role in laying the foundation for the formation of the science of epidemic febrile disease of traditional Chinese medicine in later generations.

 The book Shang Han Wei Zhi Lun(the Subtle Meanings of Shang Han), in 2 volumes, is a book on Shang Han(the theory on exogenous febrile disease), it was compiled in the year 1086 AD, by herbalist 韓祗和(Hán Zhīhé) of the Song Dynasty. The original book did not survive till today, and the printed edition of later publications is a compilation version from the book the Yongle Canon. There are 15 chapters in the book from the origin of Shang Han to the Lao Fu(recurrence caused by overexertion). It discusses pulse differentiation, the treatment methods of diaphoresis, purgation, and warming, medication and the treatment of certain diseases and syndromes, together with prescriptions and treatment cases attached. The prescriptions used are not limited to the prescriptions from Shang Han Lun(the Treatise on Cold-induced Diseases), but mostly self-established prescriptions. The various methods of diaphoresis, purgation, and warming are determined according to the three different stages according to the solar terms, after Lichun and before Qingming, after Qingming and before Mangzhong, after Mangzhong and before Liqiu. Han has many innovations in elucidating the academic experience of Shang Han Lun(the Treatise on Cold-induced Diseases), reflecting a certain degree of change and development, and his works was attached importance to for later generations. However, later herbalist 王履(Wáng Lǚ) criticized Han for "using Wenshu syndrome as a treatise on the Cold-induced Diseases" in his book 《醫經溯洄集》(Yi Jing Su Hui Ji, or the Trace Back Collection of Medical Classics), which should be paid attention to. The existing version of Shang Han Wei Zhi Lun(the Subtle Meanings of Shang Han) are engraved and lithographed editions of the late Qing dynasty, and the copy version collected in the Si Ku Quan Shu, etc.
