Shimotsu Jusen 下津壽泉 (Chinese reading: Xiàjīn Shòuquán), Edo-period Japanese paediatrician of Setsuyō 攝陽 (Settsu province, modern Ōsaka region). His paediatric handbook Yòukē zhèngzhì dàquán 幼科證治大全 (KR3ej041) was compiled at the beginning of the eighteenth century and prefaced Hōei 6 jǐchǒu suì dōng shíyuè jídàn 寶永六年己丑歲冬十月吉旦 = 1709 winter tenth month auspicious dawn at Sèyáng (Setsuyō). The work draws on Chinese paediatric authorities (the Yīlín 醫林, Xuēshì, the Yītǒng 醫統, Dàquán 大全, Hǎogǔ 好古, and others) along with Japanese clinical commentary, including the Nánfēng Lǐshì 南豐李氏 and Dōngjǐng wēng 東井翁 — both probably Edo-period Japanese physicians of the kobō-ha circle.
