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 JīnYuán 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.
