Guō Chǔxián 郭楚賢 (mid-19th-c. Qing physician, fl. 1860s). No CBDB record; biographical details otherwise unrecoverable.
His one preserved work is the Diānkuáng tiáobiàn 癲狂條辯 (KR3eh048), printed in Tóngzhì 2 = 1863 with a preface by Zhōu Chóngdì 周崇第 (the Yīlì zhǔrén 一慄主人). The work is a focused monograph on the diagnostic discrimination of diān 癲 (catatonic / withdrawal madness, classed as yīn) from kuáng 狂 (manic / agitated madness, classed as yáng), structured in five shěn 審 (examinations: shěnmài 審脈, shěnsè 審色, shěnzhèng 審症, shěnfāng 審方, wǔzàng fēnzhì 五臟分治). Guō explicitly models his framework on Yáng Lìshān 楊栗山’s Hánwēn tiáobiàn 寒溫條辨, arguing that kuáng stands to diān as warm-epidemic disease stands to cold-damage. Therapeutic principle: lǐtán wéi xiān, qīnghuǒ cì zhī 理痰為先，清火次之 (regulating phlegm comes first, clearing fire second). An appendix treats rabid-dog bites.
