Zōu Cúngàn 鄒存淦 (hào Lìshēng 儷笙, fl. 1870s, late Qīng / Guāngxù era), late-Qīng physician-scholar specialising in wàizhì (external-application therapy). Compiler of the Wàizhì shòushì fāng 外治壽世方 (KR3ed118) in 4 juǎn (the chūbiān / first compilation), printed in 1877 with the assistance of his colleague 胡增彬 (Hú Zēngbīn) of Xīnān, who served as collator and publisher. The work is the principal late-Qīng compendium devoted to non-oral therapies — poultices, plasters, fumigations, hot-compresses, steam-baths — and aimed to recover wàizhì methodology from neglect in the prevailing oral-decoction clinical mode. Sparse further biographical record.
