Táng Shènwēi 唐慎微 (zì Shěnyuán 審元, fl. 1086–1108, 北宋), Northern-Sòng pharmacopoeial scholar of Shǔzhōu Jìnyuán 蜀州晉原 (modern Chóngqìngfǔ); from a hereditary medical family. Practiced medicine without taking fees from literate-class patients but asking them in return for “famous prescriptions and secret records” (名方秘籙) — a deliberate methodological choice that made him the principal Sòng-period collector of fragmentary medical and botanical citations from the literary record. Compiled the foundational Sòng pharmacopoeia Zhènglèi bèijí běncǎo 證類備急本草 (in some recensions 31, in others 32 juan) (KR3e0028, KR3e0029, KR3e0030), drawing from over 247 prior medical works and incorporating extensive citations from non-medical literary sources where pharmaceutical material appeared (anecdote collections, encyclopedias, bǐjì, etc.). Through Táng Shènwēi’s Zhènglèi, dozens of pre-Sòng medical texts otherwise lost are partially preserved. Refused official appointment offered by Pú Chuánzhèng 蒲傳正 (Sòng Shàngshū zuǒchéng 尚書左丞). Yǔwén Xūzhōng 宇文虛中’s 1143 postface to the work — recording his childhood memory of Táng’s diagnosis of his father’s wind-poisoning, with the prediction (sealed and given to be opened only at the predicted moment) of relapse on a specific date — is the principal biographical witness.
