Lǐ Tāngqīng 李湯卿 (fl. late Yuán, c. 1280–1368), Yuán medical theorist. Biographical data unrecovered: the sole transmitted attribution is to the Xīnyìn gànzhū jīng 心印紺珠經 (KR3eo021). Doctrinally aligned with the Jīn-Yuán sìdà jiā 金元四大家 tradition, particularly the yùnqì doctrine of Lǐ Gāo (Dōngyuán). The work was referenced in the early-Míng Yīshǐ 醫史 of Lǐ Lián 李濂 (1530), which provides the principal historical anchor for placing its composition in the late Yuán. No CBDB record.
