Yīxué yuánliú lùn 醫學源流論
Discourses on the Sources and Streams of Medical Learning by 徐大椿 (Xú Dàchūn, zì Língtāi, hào Huíxī lǎorén, 1693–1771, 清)
About the work
Xú Dàchūn’s foundational theoretical-historical reflection on the Chinese medical tradition, in 2 juan, completed Qiánlóng 22 (1757). 99 essays organized under 7 great topics:
- Jīngluò zàngfǔ 經絡臟腑 (Channels and Viscera);
- Mài 脈 (Pulse);
- Bìng 病 (Disease);
- Yào 藥 (Medicine);
- Zhìfǎ 治法 (Treatment Methods);
- Shūlùn 書論 (Book-and-Discussion);
- Gǔjīn 古今 (Ancient and Modern).
The work is one of the most penetrating Chinese medical-theoretical treatises, with characteristic positions including: that pulse-types number a few dozen but disease-names number tens of thousands, requiring observation, hearing, and questioning to supplement pulse-diagnosis; that same-disease-different-people requires individualized treatment; that yùnqì doctrine should not be rigidly applied; that acupuncture has been substantially lost in transmission; and a particularly sharp argument on rénshēn (ginseng) over-use. The tíyào praises the essay collection but criticizes Xú’s tendency to over-correct popular medicine into excessive rejectionism (rejecting Qín Yuèrén / Biǎn Què, attacking established prescriptions). The work is a major source for the Confucian-medical-philological-critical movement of the high Qīng.
Tiyao
Yīxué yuánliú lùn, 2 juan, by Our Imperial Dynasty’s Xú Dàchūn. The general topics are seven: 1. Jīngluò zàngfǔ; 2. Mài; 3. Bìng; 4. Yào; 5. Zhìfǎ; 6. Shūlùn; 7. Gǔjīn. Sub-topics number 93.
His persistent argument is mostly precisely-grounded: e.g., that disease-names number ten thousand but pulse-types number only a few dozen — must be supplemented by observation-hearing-questioning; same-disease-different-people discrimination, comorbidity-and-complication distinction, yīn-loss-yáng-loss differentiation, disease-not-cured-not-dying and though-cured-must-die and medicine-error-not-immediately-killing; the changes in medicine-properties from antiquity; the Nèijīng’s sītiān yùnqì doctrine should not be rigidly applied; the loss of acupuncture method — all his arguments are useful. The Rénshēn lùn (essay on ginseng) and the Shèliè yīshū lùn (essay on browsing medical books) are particularly clear-and-pointed.
But [there are also]: places where, in trying to rescue the popular practitioner’s deficiency, [he] has over-corrected; places where, with the heart to surpass the ancients, he has spoken big-and-out-of-true. Therefore in disease-discussion, beyond QíHuáng he does not exempt even Qín Yuèrén from rebuke; in prescription-discussion…

Abstract
Composition window: 1757/1757, the date of Xú’s preface (Qiánlóng 22).
The work’s significance:
(a) The foundational Qīng medical-theoretical-historical text: at 99 essays organized under 7 great topics, the Yīxué yuánliú lùn is one of the most penetrating Chinese medical-theoretical reflections of the entire pre-modern period. The work’s combination of theoretical-historical-philological reflection on the medical tradition is one of the high points of high-Qīng Confucian-medical scholarship.
(b) The “pulse-types-few but disease-names-many” diagnostic argument: Xú’s recognition that pulse-diagnosis alone cannot suffice for the full range of clinical conditions — supplemented by observation (looking at the patient), hearing (listening to body sounds and patient’s voice), and questioning (taking history) — is one of the more methodologically sophisticated pre-modern diagnostic-epistemological positions.
(c) The Rénshēn polemic: Xú’s sharp criticism of the over-use of rénshēn in mid-Qīng popular practice — addressing both the over-prescription by physicians and the patient-driven demand — is one of the better Chinese medical-sociological observations.
(d) The over-correction critique: the SKQS editors’ balanced reading — praising Xú’s substantive contributions while warning against his polemical over-correction — is methodologically careful. Xú’s tendency to attack even Qín Yuèrén (the legendary Biǎn Què) is acknowledged as a flaw.
(e) The historical-philological orientation: Xú’s attention to medicine-property-change-over-time and to the loss of ancient acupuncture method is consistent with his broader Confucian-philological kǎojù commitment, applied to the medical tradition.
The catalog meta dynasty 清 is correct.

Other points of interest
The Yīxué yuánliú lùn — particularly the Rénshēn lùn (Ginseng Essay) and the Shèliè yīshū lùn (Browsing Medical Books Essay) — has remained influential in Chinese medical-historical pedagogy. The collection’s combination of acute clinical observation with broad philosophical-historical reflection is unusual in Chinese medical literature and represents the high point of Xú Dàchūn’s Confucian-medical-philological project.
The “99 essays” structure (on the Lao-zǐ-allusive number 99 = 9 × 11, or alternatively a long-life number) is one of Xú’s literary-aesthetic choices, locating the work in the broader Qīng medical-essay tradition.
