Chén Shìduó 陳士鐸 (c. 1627–1707), zì Jìngzhī 敬之, hào Yuǎngōng 遠公 (also Dàshān 大山), native of Shānyīn 山陰 (modern Shàoxīng 紹興, Zhèjiāng). One of the most distinctive medical writers of the early Kāngxī period and the founding voice of a late-seventeenth-century Zhèjiāng school of physician–compilers who framed their works as dialogue-revelations from Qí Bó 岐伯 and Léi Gōng 雷公. Chén states in his prefaces that in 康熙丁卯 (1687) he encountered the spirit-physician Tiānshī Qí Bó 天師岐伯 at the Tiāntán cliff of his native Shānyīn and received from him the substance of what would become his medical corpus. The CBDB entry 572125 records him without dates; lifedates here follow the prevailing modern consensus (c. 1627–1707) reflected in Volker Scheid (Currents of Tradition, 2007) and the Beijing Zhōngyīyào university medical biographical dictionaries.
His extant attributed corpus includes: Shíshì mìlù 石室秘籙 (1687), Biàn zhèng lù 辨證錄 (1687), Biàn zhèng yùhán 辨證玉函, Mài juè chǎnwēi 脈訣闡微, Běncǎo xīnbiān 本草新編, Wàijīng wēiyán 外經微言 (KR3ea051), and Dòngtiān àozhǐ 洞天奧旨. The shared device — dialogue-revelation, with Chén’s own glosses as 陳遠公曰 codas — makes the corpus internally consistent but also pseudepigraphic in style; serious Qing bibliographers (the Sìkù editors) excluded the works on these grounds. His reputation rests less on doctrinal originality than on the breadth of his materia medica recommendations (the Běncǎo xīnbiān is notable for its commercial usefulness in the post-Wàn-bǎi Quán bookmarket) and on the late-Míng / early-Qing critique of the hóngqiān (menstrual-blood elixir) cult preserved in the Wàijīng wēiyán.
CBDB 572125 carries no lifedates; the chronology used here is the modern consensus.
