Chén Qí 陳歧 (also written 陳岐), zì Yùfēng 玉峰, mid-Qing physician fl. early 18th century. Lifedates not recorded in CBDB or in the standard Qing medical biographical compilations; bracketed by internal evidence in his sole surviving work to the Kāngxī–Yōngzhèng era.
His one preserved medical work is the Yīxué chuándēng 醫學傳燈 (KR3eh013, 2 juǎn), a primer-handbook covering thirty-three commonly-encountered internal-medicine syndromes — upper juǎn on febrile, climatic and inflammatory complaints (shāngfēng 傷風, zhōnghán 中寒, shǔ 暑, shī 濕, zào 燥, huǒzhèng 火症, fēngshī 風濕, fēngwēn 風溫, shīwēn 濕溫, yǐnzhěn 癮疹, tòngfēng 痛風, láojuàn 勞倦, tánhuǒ 痰火, késòu 咳嗽, hōuchuǎn 齁喘, qīngjīn 青筋, qìnù 氣怒, zhōngè 中惡, shāngshí 傷食 etc.); lower juǎn on chronic and miscellaneous complaints (shāngjiǔ 傷酒, huángdǎn 黃疸, jījù 積聚, zhēngjiǎ 症瘕, xiánpǐ 痃癖, pǐkuài 痞塊, diānkuáng 癲狂, xiánzhèng 癇症, sānxiāo 三消, huòluàn 霍亂, nüèjí 瘧疾, lìjí 痢疾, xièxiè 泄瀉, shànqì 疝氣, jiǎoqì 腳氣, wěizhèng 痿症 +others). Each entry pairs a concise pathology-and-differential with selected formulae, in the manner of an apprentice’s pocket reference.
