Wáng Qīngrèn 王清任 (1768–1831), zì Xūnchén 勳臣, native of Yùtián 玉田 (Zhílì, modern Héběi). The most controversial and iconoclastic of the Jiāqìng / Dào-guāng-era physicians. Wáng spent decades examining corpses (in plague graveyards, exposed children’s bodies, and executed criminals at the Běijīng Càishì kǒu market) and concluded that the entire visceral anatomy of the Chinese medical canon was wrong. His findings are presented in the Yīlín gǎicuò 醫林改錯 (“Correcting the Errors of the Medical Forest”, 1830), 2 juǎn, which combines dissection-derived anatomical plates with a programme of huóxuè huàyū (blood-quickening / stasis-dispelling) prescriptions whose rationale is reconstructed zàngfǔ anatomy.
Reception was mixed in the 19th century: Wáng was attacked as illegitimate by orthodox commentators, but defended by 王學權 Wáng Xuéquán (in KR3eq089 Chóngqìngtáng suíbǐ) who used Wáng Qīngrèn’s dissection observations to test the Jesuit Rénshēn túshuō anatomy. In the 20th century his huóxuè huàyū prescriptions — Bǔyáng huánwǔ tāng, Shēntòng zhúyū tāng — became central to the PRC TCM treatment of stroke and chronic pain conditions.
