Wàikē jīngyì 外科精義
The Essential Meaning of External Medicine by 齊德之 (Qí Dézhī, Imperial Medical Erudite and External-Medicine Imperial-Physician, fl. 元)
About the work
The principal Yuán-period external-medicine (外科 wàikē: surgery, dermatology, ulcers, and general external pathology) treatise, in 2 juan. Qí Dézhī’s editorial method: discussion (lùn) before prescription (fāng), with detailed examination of the depth, gradation, deficiency, and excess (淺深虛實) of ulcer-and-swelling diagnosis. The work integrates the Zhōulǐ Tiānguān Yángyī (Officer of External Medicine) tradition’s classical principle that ulcers should be treated by both attack-of-pathogen-and-tonification-of-base — gōngbǔ jiānshī 攻補兼施 — supported by the Five Poisons (五毒: 黃堥, 石膽, 丹砂, 雄黄, 磨石, 慈石) and Five Herbs / Five Tastes / Five Grains (五氣 / 五穀 / 五藥 / 五味) classical pharmacology. The work is foundational to late-imperial Chinese external medicine. Wrongly appended to Lǐ Gǎo’s Dōngyuán shíshū (Ten Works of Dōngyuán) by Míng commercial-publishers — Lǐ Gǎo had no external-medicine practice and the Wàikē jīngyì is therefore a misappropriated work in that corpus.
Tiyao
Wàikē jīngyì, 1 juan [recte 2 juan; the tíyào’s “1 juan” is a textual slip — the catalog meta and SKQS print are 2 juan; flagged here per CLAUDE.md], by Qí Dézhī of the Yuán. Dézhī’s career-record is unclear; only his official title — Yī xué bóshì chōng Yùyào yuàn wàikē Tàiyī (Medical Erudite, Filling the Imperial Pharmacy’s External-Medicine Imperial-Physician Position) — is preserved. The compilation places discussion before prescription; on ulcer-and-swelling diagnostic depth-and-gradation and deficiency-or-excess, the analysis is most thorough.
Examining the Zhōulǐ Tiānguān: “The Yángyī manages [the medication] of swelling-ulcer (腫瘍), broken-ulcer (潰瘍), metallic-injury (金傷), and broken-injury (折傷); using the zhù (invocation), the medicine, the cleansing (劀), the killing (殺), and the qí (formulation).” Note: “劀 means scraping away pus and blood; 殺 means using medicine to consume the bad flesh.” Again: “For all ulcer-treatment, attack with the Five Poisons (五毒).*” Note: “The medical method of today has the Five Poisons prescription, combining huángméng (黃堥), shídǎn (石膽), dānshā (丹砂), xiónghuáng (雄黄), móshí (磨石), císhí (慈石) — burned for three days and three nights, the smoke-residue collected with chicken-feather and used for the wound. The bad flesh and broken bone come out completely.” Again: “Nourish with the Five qì (氣), treat with the Five Herbs (藥), regulate with the Five Tastes (味).” Note: “Once the cleansing-and-killing has cleared the dead flesh, then nourish. ‘Five qì’ should be ‘Five Grains’ (五穀) — character error. The 五味’s regulating-the-medicine’s-power.”
So in antiquity the external physician (Yángyī) practiced attack-and-tonification together. Later external physicians have wielded only attack-poison prescriptions, treating the outer without treating the inner, treating the branch without treating the root — and have lost much. Dézhī’s book aims to investigate the disease’s cause and to weigh the yīnyáng strength-and-weakness in deciding the treatment — hence in the external-medicine specialty it is the most excellent work.
In the book there is no character mentioning Lǐ Gǎo. Lǐ Gǎo himself was not famous for external medicine. The base copy is appended to the Dōngyuán shíshū (Ten Works of Dōngyuán), which is a commercial-print mash-together: this and the appended Zhū Zhènhēng work were both wrongly included to make up the “Ten Books” count. Sūn Yīkuí’s Chìshuǐ yuánzhū cites it as “Dōngyuán’s Wàikē jīngyì” — without checking, a serious error.

Abstract
Composition window: 1300–1380, the broad Yuán period during which Qí Dézhī was active. The work cannot be precisely dated.
The work’s significance:
(a) The principal Yuán-period external-medicine treatise: the Wàikē jīngyì is the most thorough surviving Yuán-period treatise on external medicine. Through it we have access to Yuán-period surgical and dermatological-medical practice, much of which was inherited from the lost HànSuíTáng tradition.
(b) The internal-and-external integrated approach: Qí Dézhī’s emphasis on treating both the inner (the patient’s underlying constitutional state) and the outer (the local lesion) — combined with the attack-pathogen-and-tonify-base principle — is a sophisticated integrated approach to external pathology. This anticipates the modern surgical understanding that wound-healing depends on the patient’s overall constitutional state.
(c) The classical Zhōulǐ Yángyī tradition: Qí grounds his work explicitly in the Zhōulǐ’s description of the Yángyī (Officer of External Medicine), the earliest Chinese systematic statement of external-medical practice. The grounding in classical-textual reasoning is consistent with the broader JīnYuán medical revolution’s classical-textual orientation.
(d) The Dōngyuán shíshū misattribution and SKQS correction: a useful piece of mid-Qīng philological work, distinguishing the genuine Lǐ Gǎo corpus from later misappropriated material. The SKQS editors’ correction restores the genuine Yuán-period attribution and frees Lǐ Gǎo from a non-authentic external-medicine work.
The catalog meta gives the tíyào’s opening as “1 juan”, but the actual recension and the catalog are 2 juan — flagged here as a textual slip per CLAUDE.md.

Other points of interest
The “Five Poisons” (五毒) classical prescription — the burning of huángméng, shídǎn, dānshā, xiónghuáng, móshí, císhí together for three days and three nights, with the soot then collected and applied to wounds — is one of the more interesting Chinese pre-modern surgical-pharmacological preparations. The combination of mercury sulfide (cinnabar / dānshā), copper sulfate (shídǎn), arsenic sulfide (xiónghuáng), and other heavy-metal compounds produces a pharmacologically active soot with strong antiseptic (and toxic) properties. Modern phytochemistry has documented substantial antibacterial activity in such preparations, suggesting genuine clinical efficacy alongside the obvious heavy-metal toxicity.
The Confucian-ritual reading of the Zhōulǐ Yángyī passage as a foundational document of Chinese external medicine is one of the more interesting cases of cross-genre classical-textual integration: the Zhōulǐ is normally read as a political-and-ritual document, but Qí Dézhī treats it as a medical document, and the SKQS editors approve.
