Qián Jùn 錢峻 (zì Qīnglún 青掄, fl. late Kāngxī era; native of Wúxīng 吳興 / Húzhōu 湖州, Zhèjiāng; deceased shortly after summer 1707), late-Qīng physician and merit-publishing pharmacologist. Compiler of the Jīngyàn dānfāng huìbiān 經驗丹方彙編 (KR3ed112), a dānfāng (single-drug formula) compendium of approximately 800 prescriptions accumulated over a decade of personal clinical practice. According to his own preface dated Kāngxī dīnghài 1707, Qián’s father Tínglì gōng 亭立公 charged him on his deathbed to continue the family tradition of jīdé (merit-accumulation); Qián’s own pulmonary illness (recurrent blood-spitting, probably tuberculosis) drove him to abandon his examination-career for medical practice and to compile the Dānfāng huìbiān. The preface is written under the conviction of imminent death; the work was brought to press by Qián’s friend Xú Yún 徐芸 and a small posthumous circle. Sparse further biographical record; not in CBDB.
