Xú Chūnfǔ 徐春甫 (zì Rǔyuán 汝元, hào Dōnggāo 東皋, c. 1520 – c. 1596), Hīzhōu Qímén 祁門 physician of the mid-late Míng and one of the most important Wàn-lì-era medical figures. Active for much of his career at the Imperial Academy of Medicine (Tàiyī yuàn 太醫院) in Běijīng, Xú founded the Yīlín yīshè 醫林一體社 (Medical-Forest Medical Society, 1568) — the first formal medical-professional organisation in China, with a regulatory and pedagogical charter modelled on the Confucian xuéshè 學社 (learning-societies). His principal works are the encyclopaedic KR3er031 Gǔjīn yītǒng dàquán 古今醫統大全 (1556, a hundred juǎn) and the Jīngluò qìtǒng tújiě 經絡氣統圖解 (KR3eb046). Xú’s clinical doctrine was YìshuǐDānxī integrated, with a strong emphasis on the zhīběn 知本 (knowing-the-root) principle that the prefacer Yáng Shìqí identified with Zhāng Yuánsù’s spleen-earth therapeutics.
