Yī zhōng yī dé 醫中一得
A Single Insight in the Medical Way by 顧爾元 Gù Ěryuán (zì Yǎtíng 雅亭, of Liángxī 梁溪 = Wúxī 無錫, fl. 1730s–1803).
About the work
A one-juǎn mid-Jiā-qìng-era short clinical-doctrinal essay by Gù Ěryuán, a qīshì jiāyī 七世家醫 (seventh-generation hereditary physician) of Liángxī (Wúxī, in the Sūzhōu region). Composed in Jiāqìng 8 / 1803 zhòngchūn (second spring month), when Gù was 74 suì, the work distills the principal yī dé — “one [significant] insight” — of his half-century clinical career: the proper treatment of dānnüè 癉瘧 (single-tertian / summerheat malaria with damp accumulation).
The work argues against the prevailing late-Qīng practice of treating dānnüè with the standard biǎolǐ shuāngjiě 表裡雙解 (simultaneous outer-and-inner resolution) approach derived from the Shānghán tradition. Gù’s clinical position, developed in dialogue with 葉桂 Yè Tiānshì’s doctrine that shǔ wéi wúxíng zhī qì, xiān cóng kǒubí ér rù 暑為無形之氣，先從口鼻而入 (“summerheat is a formless qì, entering first through mouth and nose”), is that dānnüè is essentially a fèiwèipí 肺胃脾 triple-organ damp-heat pattern requiring xīnliáng jiěsàn 辛涼解散 (pungent-cool outer-resolution) with shēngmá 升麻 as the indispensable axial drug — to lift the trapped qīngqì 清氣 of the spleen and allow the damp-heat exudate to exit via the lung and stomach channels rather than being driven into the interior (where SòngYuán xiàfǎ 下法 protocols would lead).
The signature formula of the work is Gěshēng tāng 葛升湯, composed of gěgēn 葛根 (1.5 qián), shēngmá 升麻 (8 fēn), liánqiáo 連翹 (2 qián), xìngrén 杏仁 (2 qián roasted), niúbàng zǐ 牛蒡子 (3 qián), liùyī sàn 六一散 (3 qián), guǎngpí 廣皮 (1 qián), chányī 蟬衣 (1 qián legs removed), chuān tōngcǎo 川通草 (4 fēn), and xiāngrú 香薷 (1 qián), introduced with lúgēn 蘆根 (1 liǎng), héhuā lù 荷花露 (1 liǎng), fresh hégěng 荷梗 (1 chǐ), and fresh fóshǒu 佛手 (1 qián). Gù gives detailed dosage adjustments by patient constitution and seasonal timing, with characteristic emphasis on shēngmá as the load-bearing drug: “without shēngmá, this formula cannot achieve its effect.”
Prefaces
The hxwd _000.txt carries Gù’s self-preface dated guǐhài zhòngchūn yuè 癸亥仲春月 = Jiāqìng 8 / 1803 second month, signed Liángxī qīshì jiāyī Yǎtíng shì Gù Ěryuán bài zhuàn, shí nián qīshí yǒu sì 梁溪七世家醫雅亭氏顧爾元拜撰，時年七十有四 (“authored at the age of seventy-four”). The preface opens with the Shījīng 詩經 quotation wǒ sī gǔrén, shí huò wǒ xīn 我思古人，實獲我心 (“I think of the ancients — truly they have grasped my heart”), glossed: huò 獲 = dé 得 (“grasp” = “obtaining” = “an insight”); citing the Confucian-pedagogical topos of fāfèn wàngshí, lè yǐ wàngyōu 發憤忘食，樂以忘憂 (“learning is a matter of having insight”). Gù lists the historical yǒu dé exemplars: Huángdì / Qíbó / Zhāng Zhòngjǐng as the yīzhōng zhī shèng 醫中之聖; the Sì dàjiā (Liú Héjiàn, Lǐ Dōngyuán, Zhū Dānxī); then Yè Xiāngyán’s editorial reprint of Tāo Huá’s Jīnshēng jí 金生集; Xú Língtāi’s evaluation of Yèshì fāngàn 方案 (KR3er086 and its companions).
The hxwd _000.txt also includes a fùlù 附錄 appendix: the correspondence between Gù and Wú Fǔtián 吳俯恬 of Chéngjiāng Huáshù zhèn 澄江華墅鎮 (Jiāngyīn 江陰 region), who had read the manuscript and posted Gù further comments and queries.
Abstract
The 1803 dating is established beyond doubt by the self-preface (cyclical guǐhài = Jiāqìng 8) and Gù’s stated age of 74 suì — yielding a birth-year of c. 1730 (Yōngzhèng 8). The qīshì jiāyī 七世家醫 designation places Gù as the seventh generation of a Wúxī medical lineage active from the late Míng. Not in CBDB under this identification.
The work is a notable mid-Jiā-qìng formulary intervention in the post-Yè Tiānshì wēnbìng tradition: it explicitly aligns itself with Yè’s pioneering doctrine of shǔyì 暑邪 (summerheat-disorder) as a wúxíng zhī qì upper-burner illness, refines Yè’s clinical method with a specific shēngmá-based formula, and represents the transmission of the Sūzhōu wēnbìng tradition into the Wúxī medical milieu through the early 19th c.
Translations and research
No European-language translation of the Yī zhōng yī dé located. For the post-Yè Tiān-shì wēn-bìng tradition in the early 19th c. see Marta Hanson, Speaking of Epidemics in Chinese Medicine (Routledge, 2011), and Volker Scheid, Currents of Tradition (Eastland, 2007).
Other points of interest
The work is a clear specimen of the post-Yè Tiānshì jiāchuán 家傳 (family-transmission) medical tradition’s adoption of wēnbìng doctrine in the early 19th c. — Gù was a seven-generation hereditary physician of Wúxī, and his refinement of Yè’s shǔyì doctrine into a specific Gěshēng tāng formula represents the practical integration of wēnbìng theory into hereditary clinical practice.
