Yú Chāng 喻昌 (zì Jiāyán 嘉言, 1585–1664, 清), late-Míng / early-Qīng physician of Xīnjiàn 新建 (modern Nánchāng, Jiāngxī). Major works in the SKQS / Kanripo:
- Shànglùn piān 尚論篇 (KR3e0091, 8 juan, 1648) — full title Shànglùn Zhāng Zhòngjǐng Shānghán lùn chóngbiān 397-fǎ 尚論張仲景傷寒論重編三百九十七法 — the principal early-Qīng Shānghán “ancient-text-restoration” work, building (per 方有執 Fāng Yǒuzhí’s defenders’ charge of plagiarism) on Fāng’s Tiáobiàn (KR3e0082);
- Yī mén fǎlǜ 醫門法律 (KR3e0092, 12 juan) — comprehensive medical-ethics-and-clinical-method treatise.
Yú was an influential clinician with a Buddhist cānChán background (he had earlier been a monk before returning to Confucian life) and is known for his strict, careful clinical approach. The Lín Qǐlóng 1674 reprint of Fāng Yǒuzhí’s Tiáobiàn fiercely accused Yú of plagiarizing Fāng’s work; Yú’s school defends his independent contribution. The Yī mén fǎlǜ is one of the more articulate Chinese medical-ethics works, and the Shànglùn piān one of the most widely-circulated late-imperial Shānghán-revisionist texts. The catalog meta dynasty 清 is correct; lifedates b. 1585 with d. 1664.
