Abstract

Shanghan Lun Zhu and Shanghan Lun Yi, both associated with Ke Qin, each present “three methods for treating water” across the upper, middle, and lower burners, yet Wuling San does not occupy the same position. In the inspected Shanghan Lun Zhu witness, Xiao Qing Long Tang, Shi Zao Tang, and Wuling San occupy the upper, middle, and lower positions respectively. In Shanghan Lun Yi, Wuling San is paired with Xiao Qing Long Tang in the upper-burner clause, while Gui Zhi Qu Gui Jia Ling Zhu Tang occupies the lower clause. We compared normalized transcriptions, independent public transcriptions, and facsimile pages. The result shows that the symptom–method–formula arrangement was not stably repeated under the same heading. It does not by itself establish authorial intent, the exact moment of revision, or an edition genealogy. Contemporary formulary and paediatric uses provide secondary context for other editorial units in which Wuling San was invoked.

Is a formula position fixed within one authorial system?

When looking up Wuling San, we usually begin by asking what the formula is used for. Yet opening two books associated with Ke Qin raises a prior question. Both Shanghan Lun Zhu and Shanghan Lun Yi divide the treatment of water into the upper, middle, and lower burners, but they place Wuling San differently: below in one book and above in the other. This study asks whether that difference is merely verbal or whether the whole passage has been reorganized. Bibliographic and formula information helped locate the candidate passages, after which the wording around `治水有三法` and `五苓散` was checked directly in transcripts and public facsimiles. Search and automated summaries helped locate the texts; the judgment rests on the two primary passages reproduced below.

Ke Qin’s system in prior scholarship—and an unasked textual difference

Scholarship on Ke Qin has chiefly explicated the six-channel and pattern-differentiation system of Shanghan Lun Yi. Jang and Hong interpret the six channels not as a fixed anatomical map but as a system for distinguishing presentations and deploying methods and formulas [6] . Lee, through the “Explanation of Greater Yang Disease,” argues against reducing Greater Yang to the Bladder channel alone and reads it as a layered domain involving the Heart, Lung, and nutrient–defence circulation [7] . These studies provide the background for reading a formula’s location as a contextual relation rather than a fixed label.

The located scholarship, however, does not directly collate the two “three methods” passages from Shanghan Lun Zhu and Shanghan Lun Yi across the same four columns—symptom, location, method, and formula. The contribution here is therefore not a new total account of Ke Qin’s doctrine. It turns the existing systemic reading into a narrower reproducible comparison and identifies where a fixed tag such as “Wuling San = lower burner” breaks even within the same attributed corpus.

Shanghan Lun Zhu: Wuling San in the lower burner

The inspected Shanghan Lun Zhu passage assigns dry retching and cough to water in the upper burner and Xiao Qing Long Tang; epigastric fullness to the middle burner and Shi Zao Tang; and inhibited urination to the lower burner and Wuling San [1] . The transcript agrees with facsimile PDF pages 66–67 (printed pages 53–54). In this witness, Wuling San occupies the third position, which draws off water below.

Shanghan Lun Yi: Wuling San in the upper burner

Under the same heading in Shanghan Lun Yi, vomiting immediately after drinking is added to the upper-burner description, and Wuling San is paired with Xiao Qing Long Tang. The lower burner is described as heat entering the bladder with inhibited urination, for which Gui Zhi Qu Gui Jia Ling Zhu Tang is assigned [2] . The complete clause was verified in the transcript and on facsimile PDF page 39 (printed page 31).

Reorganization rather than repetition

The difference is not merely the movement of one formula. Shanghan Lun Yi expands the upper-burner symptom and method, adds Da Xian Xiong Tang to the middle, and changes the lower-burner symptom and formula. The entire symptom–location–method–formula relation is reorganized. The direct comparison supports the bounded conclusion that the two inspected texts do not repeat one stable schema.

There are three rivals. First, an intentional authorial revision is possible, but remains unresolved because authorial-copy status, publication sequence, and edition genealogy have not been established. Second, a one-formula move from lower to upper does not fit the evidence: the upper symptom and method, the middle formula, and both lower symptom and formula also change. Third, later editing, transcription, or edition history may account for part of the difference and cannot yet be excluded. The strongest conclusion is therefore not an authorial motive but the observed difference between the relational schemas of the two inspected passages.

Contemporary context and limitations

In contemporary material, Gujin Mingyi Fanglun contrasts Wuling San and Zhen Wu Tang through excess and deficient water; Xiaoer Tuina Guangyi presents a concise paediatric entry for diarrhoea and inhibited urination; and Youke Zhengzhi Zhunsheng invokes it in contexts of inhibited urination and acute fright-wind [3, 4, 5] . These are contextual witnesses, not direct genealogical evidence explaining Ke Qin’s two passages.

This study compares acquired facsimiles and normalized transcriptions and does not collate every surviving edition. Bibliographic dates remain provisional metadata, and no modern clinical effectiveness or safety claim is evaluated.

Conclusion

The answer is no: Wuling San does not occupy the same place. It represents lower-burner water in Shanghan Lun Zhu, but is paired with Xiao Qing Long Tang in the upper burner in Shanghan Lun Yi, where another formula takes the lower position. Because other slots change too, the observed difference is a reorganization of the passage rather than a one-formula move. Retrieval over large classical corpora must therefore capture not only formula-name occurrences but the surrounding symptom–location–method–comparison relations.
