Ikeda Zuisen 池田瑞仙 (1734–1816), Edo mid-to-late-period Japanese kanpō 漢方 physician, native of Iwakuni 岩國 in Suō 周防 (modern Yamaguchi). Given name Dokumi 獨美. The leading family-tradition smallpox specialist of the Edo period.
The Ikeda family’s specialised practice was paediatric smallpox (tōka 痘科). During major smallpox epidemics Ikeda was summoned to treat patients in Kyoto and Osaka. He was later appointed to the Bakufu Medical Academy 幕府醫學館 (Igakukan) as instructor in smallpox science, and was eventually the senior smallpox-instruction official of the academy. His son Ikeda Yin 池田奫 succeeded him in the same office; Murakaoka Shin 村岡晉 served as the second-generation Bakufu smallpox-instruction official.
His major surviving work is the Tōka benyō / Dòukē biànyào 痘科辨要 (KR3eg046) in 10 juǎn, with substantial editorial history detailed in his son Ikeda Yin’s Chóngjiào dòukē biànyào xù 重校痘科辨要敘 (Bunka 4 = 1807). The book was transmitted to China and included in Huáng Hàn yīxué cóngshū 皇漢醫學叢書, vol. 9 (Shanghai: Shìjiè Shūjú, 1936).
