Yáng Shítài 楊時泰 (c. 1786 – c. 1839), zì Mùrú 穆如, native of Jīntán 金壇 (Chángzhōu prefecture, Jiāngsū). Early-19th-century Jiāngnán physician and bùjí official; held minor county-level posts (令山左 — “magistrate in Shāndōng”) and combined administrative duty with clinical practice — Zōu Shù 鄒澍 (his close friend and the preface-writer for the Běncǎo shù gōuyuán) called him “以良吏而兼良醫” (“a good official who is at the same time a good physician”). His major work is the Běncǎo shù gōuyuán 本草述鉤元 (KR3ec052, printed 1842), a critical condensation of the late-Míng physician Liú Ruòjīn 劉若金’s Běncǎo shù 本草述: Yáng reduced Liú’s verbose original by approximately 40% while making explicit the qìwèishēngjiàng 氣味升降 systematic that Liú’s prose had obscured. He died before printing; the work was published posthumously by his disciple Wǔ Zhòngcháng 伍仲常. There are five CBDB entries under the name, but none with confident lifedates matching this physician; no confident CBDB id assigned here.
