Hé Qíwěi 何其偉 (hào Shūtián 書田, 1774–1837, CBDB 78781), Qing physician of Qīngpǔ 青浦 (modern Shanghai region), member of the long Héshì 何氏 hereditary medical lineage. Best known historically as the physician consulted by Lín Zéxù 林則徐 during the opium-suppression campaign in Guǎngdōng — Hé’s anti-opium prescriptions (jìsuān wán 忌酸丸 and bǔzhèng wán 補正丸) were promulgated by Lín in Guǎngdōng for the medical treatment of opium addicts.
His principal medical work is the Yīxué miàodì 醫學妙諦 (KR3eh017, 3 juǎn in 76 sections), a didactic family-school primer covering internal, gynaecological, and paediatric medicine in seven-syllable mnemonic verse (qīyán gēkuò 七言歌括) with prose commentary, designed for memorised clinical reference. Much of the work was lost in the 1860 Tàipíng-era bīngxiè 兵燹 in the Lower Yángzǐ; the received recension was reconstructed by Chén Mòsūn 陳墨蓀 from manuscript copies and printed at YúnnánGuìzhōu in 1892, with a preface by Wáng Wénsháo 王文韶.
