Yīfǎ yuántōng 醫法圓通
The Penetrating Comprehension of Medical Method by 鄭欽安 Zhèng Qīnān (míng Shòuquán 壽全, zì Qīnān 欽安, 1804–1901, Línqióng 臨邛 / Qióngzhōu 邛州, Sìchuān).
About the work
A four-juǎn late-Qīng clinical-doctrinal treatise — the second of the three principal works of Zhèng Qīnān, the founder of the Huǒshén pài 火神派 (“Fire-Deity School”) of Sìchuān medicine. The work is the practical-clinical sequel to Zhèng’s earlier Yīlǐ zhēnchuán 醫理真傳 (1869), and elaborates Zhèng’s signature clinical-doctrinal position: that the fundamental pathomechanism of essentially all serious disease is yángxū 陽虛 (depletion of yang), specifically the depletion of the xiāntiān zhī yáng 先天之陽 (pre-celestial yang) located at the Mìngmén 命門 between the two kidneys, and that the principal therapeutic strategy must therefore be large-dose warming-and-tonifying with the “yang-restoring” trio of fùzǐ 附子 (aconite), gānjiāng 乾薑 (dried ginger), and guìzhī 桂枝 (cinnamon twig). Zhèng’s clinical signature is the heavy use of fùzǐ (sometimes 60–100 qián per decoction — quantities considered radically dangerous in conventional practice) and the resulting clinical reputation as the Fùzǐ Zhèng 附子鄭 (“Aconite Zhèng”).
The Yīfǎ yuántōng is organised as a sequence of clinical-pattern essays, each developing a particular biànzhèng 辨證 (pattern-discrimination) problem and demonstrating Zhèng’s diagnostic and therapeutic reasoning. The work systematically applies the Shānghán lùn’s six-channel pattern-system to internal medicine generally, treating both shānghán 傷寒 (cold-damage) and zázhèng 雜證 (miscellaneous patterns) within a single unified clinical-reasoning framework.
Prefaces
The hxwd _000.txt carries two prefaces dated to Tóngzhì 13 / 1874: (i) the preface of Zhīfēi jìngshì 知非敬氏 of Máchéng 麻城 (Húběi), dated Tóngzhì shísān nián jiǎxū zhōngqiū 同治十三年甲戊中秋, written from his Jǐnchéng Lúshān xiānguǎn 錦城廬山仙館 residence (Jǐnchéng = Chéngdū); (ii) the preface of Shěn Gǔzhāi 沈古齋 (zì Huàsān 化三, of Pítǒng 郫筒 = Píxiàn 郫縣, Sìchuān), dated the same Tóngzhì shísān nián but in pújié yuè 蒲節月 (Dragon-Boat month, fifth lunar month). Additional shorter prefaces follow.
The opening passages of the prefaces narrate the prefacers’ encounter with Zhèng’s earlier Yīlǐ zhēnchuán — a “book that grasps something of xìnglǐ 性理 (the principle of nature) and uses medicine to make it clear” — and Zhèng’s responsive composition of the present Yīfǎ yuántōng in answer to the practical clinical questions the first work had raised.
Abstract
Zhèng Qīnān (1804–1901) was a Chéng-dū-area physician, jǔrén of Dàoguāng 24 / 1844 in some sources (not securely confirmed), who became the founding voice of the Sìchuān Huǒshén pài — a regional medical tradition specifically distinguished by its anti-wēnbìng clinical posture and its emphasis on large-dose yáng-warming therapy. The Yīfǎ yuántōng is securely dated to Tóngzhì 13 / 1874 by its publication prefaces. Zhèng’s third major work, the Shānghán hénglùn 傷寒恆論, appeared subsequently. Zhèng is not in CBDB.
The Huǒshén pài has had an unusually robust modern afterlife: its 20th-c. and 21st-c. revival, associated principally with the contemporary Sìchuān clinician Lú Chónghàn 盧崇漢 and his predecessors Wú Pèihéng 吳佩衡 and Fàn Zhōnglín 范中林, has made Zhèng’s three works among the most-discussed Qīng medical texts in present-day PRC TCM debates. The hxwd recension descends from the Tóngzhì 1874 editio princeps through a Japanese reprinting.
