Xǔ Shūwēi 許叔微 (zì Zhīkě 知可, ca. 1080 – ca. 1154, 南宋), Southern-Sòng physician of Yángzhōu / Pílíng / Zhēnzhōu (sources differ; Zēng Mǐnxíng’s Dúxǐng zázhì gives Zhēnzhōu 真州 as native place). Sat for the Shàoxīng 2 (1132) examination under examiner Zhāng Jiǔchéng 張九成 and placed sixth — hence the contemporary medical-literary epithet Xǔ Xuéshì 許學士 (Scholar Xǔ). His official career is unrecorded. One of the major Sòng-period commentators on the Shānghán lùn, a key figure in the Sòng Shānghán-line tradition listed by Dài Liáng’s Jiǔ líng shānfáng jí alongside Wáng Shūhé, Chéng Wúyǐ, Páng Ānshí, Zhū Hóng, 韓祗和 Hán Zhīhé, and Wáng Bīnzhī. Xǔ’s transmitted works include the Lèizhèng pǔjì běnshì fāng 類證普濟本事方 (KR3e0032, 10 juan, completed 1133) — a clinical formulary in which each prescription is accompanied by an associated yī àn (case-record); the title plays on the famous Běnshì shī 本事詩 (Tang poem-anthology with associated anecdotes), here rendered “Original-Case Prescriptions”. Other works (referenced by Zhū Guózhēn 朱國禎’s Yǒng chuáng xiǎo pǐn 湧幢小品 but lost in transmission) include the Nǐ Shānghán gē 擬傷寒歌 (3 juan, 100 pieces), Zhìfǎ 治法 in 81 篇, Zhòngjǐng màifǎ sānshíliù tú 仲景脈法三十六圖, Yì Shānghán lùn 翼傷寒論 (2 篇), and Biàn lèi 辨類 (5 juan).
