Where Was Wuling San Placed? Reorganization of the Three Methods for Treating Water in Shanghan Lun Zhu and Shanghan Lun Yi
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.
