Guō Zhìsuì 郭志邃 (zì Yòutáo 右陶, mid-17th c., 清). Native of Zuìlǐ 檇李 (modern Jiāxīng 嘉興, Zhèjiāng). Early-Qīng physician — a Confucian-trained scholar who, after the Míng–Qīng transition, abandoned the kējǔ path and turned to medicine for his livelihood, specialising in shā 痧 disorders.
Author of the foundational Shāzhàng yùhéng 痧脹玉衡 (KR3eg037), preface dated dēngyuè (first lunar month) of Kāngxī 14 = 1675, signed “Guō Zhìsuì Yòutáo at the Yǔxiántáng 寓賢堂”. The book is the foundational Chinese monograph on shā disorders (a wide and ill-defined category encompassing acute febrile / cramping / diarrhoeal syndromes attributed to “noxious miasma” shāqì 痧氣 — variously identified with cholera-like presentations in later commentary).
Three years after the book was completed, Guō added a fourth (continuation) juǎn from further clinical observations. He also authored Zhì shā yàoluè 治痧要略 (Essentials of Treating Shā), which has not survived.
Despite his focus on a folk-medical category, Guō’s clinical idiom is recognisably Confucian-physician: he uses pulse diagnosis throughout and combines the guā fǎ 刮法 (scraping), fàngshā 放痧 (sha-releasing) and oral medicinal therapy as a coordinated apparatus — rather than (as folk shā practitioners did) relying primarily on scraping.
