Lǐyuè piánwén 理瀹駢文
Parallel-Prose [Treatise on] the Principle of Curing by 吳師機 Wú Shījī (1806–1886, zì Shàngxiān 尚先, Qīng physician of Qiántáng 錢塘 [Hángzhōu]) — the foundational text of Chinese external therapy (wàizhì 外治).
About the work
A two-juan treatise — written in elaborate parallel prose (piánwén 駢文, a self-consciously elevated literary register) — that is the single most important text in the history of Chinese external therapy (wàizhì) and specifically of plaster-and-poultice therapy (báotiē 薄貼). Wú Shījī’s revolutionary doctrinal claim is that the Shānghán and Wēnbìng internal-disease canons, conventionally treated only by tāngyè 湯液 (oral decoctions), can be systematically treated by plasters and poultices applied externally — that the qì of the medicinal compound enters the body through the 84,000 fine pores of the skin as readily as through the digestive tract, and that wàizhì therefore can replace internal medication for the entire internal-medicine syndrome-set, juncture by juncture.
Prefaces
The transmitted xù is by an anonymous editor narrating the work’s reception: “*Human beings are within the interchange of qì. All breathed-and-exhaled qì is the yuánqì of Heaven-and-Earth. Where wild wind, sudden rain, fierce cold, sticky summer, mountain-mist plague-vapours strike, and to the self-injuries of the emotions, the harms of hunger-and-satiety and toil, the changes of sudden-violence — the yuánqì is injured and illness arises. Inside it strikes the viscera; outside it manifests in the limbs. Those who treat have accordingly distinguished internal and external as separate disciplines. Decoctions — the internal-treatment. As for external treatment, it is mostly báotiē — but [conventionally] applied to treating-the-exterior while abandoning the decoctions. — But Heaven does not stint of the Dào, and Mr. Wú of Qiántáng, Shàngxiān, has been the first to specially employ báotiē for treating-the-interior — and never in antiquity has this been. Mr. Wú bore the will of saving-the-world but was sparing in his medical practice. In recent years he settled in the north-eastern village of Hǎilíng (Tàizhōu, Jiāngsū), employing báotiē to treat patients — constantly ten-cured-of-ten. Among the xìnglín (apricot-grove of doctors), without speech he formed a path. Some doubted, suspicious of how interior treatment could be exteriorly obtained. They did not know that this too is taking the qì. — When today one bathes facing the wind, cold qì enters; when one moves in summer, hot qì enters. What enters is internal, but what causes its entry is external — not internal. The 84,000 fine pores of the human body are all the byway by which qì enters and departs — not just the mouth and the nose.”
The preface continues with Wú’s own self-presentation: “Mr. Wú, however, never instructed people in external-rather-than-internal therapy. He once produced for me his Lǐyuè piánwén; receiving it I read it: from the Líng [shū] and Sù [wèn] downward, [he had] widely collected and tightly selected, gathering all without omission, but not vulgarly esteeming the prescriptions and intentions — knowable. Yet he proceeded resolutely from external treatment — what is the reason? [He answered]: if reading my book one obtains something, then external treatment is not pure intention; one may change and follow decoctions — why not? If one has not yet obtained anything, then provisionally use my treatment as treatment; if it does not strike, removing it is no difficulty — one may receive the benefit of decoctions without their harm.”
Abstract
The Lǐyuè piánwén (the title is allusive: lǐyuè 理瀹 = “principle of curing” / “curing by principle”; piánwén = the parallel-prose literary genre) is the single most important text in the history of Chinese external therapy (wàizhì xué 外治學). Wú Shījī’s doctrinal innovation — the systematic extension of plaster-and-poultice therapy from its conventional role in exterior conditions to the entire range of internal-medicine syndromes — is one of the major nineteenth-century innovations in Chinese clinical practice and has been the foundation of the modern wàizhì sub-discipline of Chinese medicine.
Wú composed the work during his exile / refugee residence at Hǎilíng (Tàizhōu) in the aftermath of the Tàipíng war (post-1864), where his cosmopolitan Qiántáng practice was reduced to small-town village medicine — and where, in straitened circumstances, he employed báotiē therapy from necessity (it is cheaper than tāngyè) and observed its surprising effectiveness across the internal-medicine spectrum. The work was first published in 1870.
The work’s distinctive parallel-prose literary register — Wú deploys highly elaborated piántǐ with extensive classical allusion throughout — is itself part of his rhetorical strategy: by writing in the literati high-style, he stakes the work’s claim to the canonical Sùwèn / Língshū lineage rather than to the popular-medical / shànshū register that conventional báotiē manuals occupied. The work was instrumental in transferring wàizhì practice from the artisanal / folk-medical sphere into the literate-medical mainstream.

Other points of interest
The work’s argument — that the 84,000 fine pores (a Buddhistically-derived numerological figure for the totality of bodily surface) function as a uniform pathway for therapeutic-substance entry — is one of the most striking nineteenth-century Chinese-medical doctrinal claims, and represents a major conceptual innovation: it dissolves the conventional rigid separation between “exterior” and “interior” therapy, treating the skin as a generalised absorption surface continuous with the digestive tract.
