补充资料：《痧胀玉衡》
《痧胀玉衡》 《痧胀玉衡》 痧胀专著。三卷。清·郭志邃撰于1675年。作者鉴于痧胀病症发病多、传变快，治不对症，命在须臾，遂搜求前人有关痧胀的医学文献和学术经验，总其大纲，撮其要领，编成此书，系统全面地论述痧胀。上卷列痧胀发蒙论、痧胀要语及痧胀脉法；相当于总论。中卷、下卷结合实际治例、叙述多种痧证，末附备用要方。是为各论。书成后三年，郭氏从临床实践中意识到“痧之变幻，有隐伏于别病中者”（见本书续序），又作后卷一卷，补充了不少有关痧症的诊治内容。但作者根据痧症的临床表现，分症过细，显得名目繁多；在解释病因、证候等方面，或有附会的观点。本书有初刻本等多种刊本。1949年后有排印本。
