Wáng Qīngyuán 王清源 ( Fùyuán 馥原, fl. mid-late 19th c., 清) was a Shānyīn 山陰 (modern Shàoxīng 紹興) physician who devoted “more than twenty years” to the careful compilation of the Yīfāng jiǎnyì 醫方簡義 KR3ed073, a 6-juǎn analytical formulary intended as a corrective to the careless extracting and indiscriminate prescribing he saw in his contemporaries. He is described as a follower of Zhāng Zhòngjǐng’s clinical reasoning rather than of any post-Sòng school’s polemical doctrine. The work’s preface — a typical late-Qīng — was contributed by a senior contemporary who praises Wáng’s “removing personal opinion and weighing each formula in zhū and liǎng.” No CBDB entry.
