Liǔ Bǎoyí 柳寶詒 (1842–1901, CBDB 84838), zì Gǔsūn 谷孫 (also given 冠群), late-Qīng physician of Jiāngyīn 江陰 (Jiāngsū). One of the principal late-Qīng exponents of the latent-qi (fúqì 伏氣) theory of wēnbìng and a major figure in the Jiāngyīn medical tradition.
His best-known work is the Wēnrè féngyuán 溫熱逢源 (KR3eg003) in 3 juǎn, a systematic exposition of latent-qi warm-disease theory grounded in close re-reading of the Nèijīng and Shānghán lùn. The book did not see print during Liǔ’s lifetime but was included in the Sānsān yīshū 三三醫書 collectanea edited by Qiū Qìngyún 裘慶元 in the Republican period.
Other works include Liǔ Xuǎnqìng yīàn 柳選慶醫案 and Wēnrè cǎn jiē 溫熱讖解.
