Wú Qǐ 吳杞 (zì Zhàngxiān 杖仙, “the Cane-Immortal”, fl. mid-Qiánlóng era, ca. 1720s–1750s), Qīng gentleman-physician of Āndé 安德 (Ānhuī province). According to his self-preface to the Wúshì yīfāng huìbiān 吳氏醫方彙編 (KR3ed127), Wú had been afflicted with a tongue-disease in 1734 (jiǎyín) which physicians failed to cure; he treated himself successfully and from that experience turned to systematic medical study. He practised broadly in his Wǎnxiāngtáng 晚香堂 (“Studio of Late-Evening Fragrance”) clinic at Āndé and prepared his own drugs by hand. His 1744 Wúshì yīfāng huìbiān in 4 juǎn is a wàikē (external-medicine) specialty formulary in the mid-Qiánlóng revival of surgical-clinical practice. Sparse further biographical record.
