Wāng Pǔzhāi 汪樸齋 (fl. mid-18th c. 清), Qiánlóng-era obstetrical physician. The author of the Chǎnkē xīnfǎ 產科心法 (Heart-Method of Obstetrics), a working obstetrical-manual that circulated only in manuscript during his lifetime. The text was first cut for print by Lǐ Chāohéng 李超恆 of Shímén 石門 (Zhèjiāng) in 1804 (Jiāqìng 9), and supplied with extensive critical annotations and a Wǔzǐ zhǒngyù dān “Five-Sons Seed Pellet” appendix on infertility treatment, then re-printed in revised form. The work was further annotated and prefaced through the nineteenth century — culminating in the Píngzhù chǎnkē xīnfǎ 評註產科心法 (KR3ei069) of late Qīng. Pǔzhāi is the author’s hào; his given name and native place are not recorded in the surviving prefaces. Not in CBDB.
