Gōng Jūzhōng 龔居中 (zì Yìngyuán 應圓, fl. late Wànlì to Tiānqǐ era, c. 1610–1640), late-Míng physician of Jīnxī 金谿 (Jiāngxī). No CBDB record.
His principal work is the Tánhuǒ diǎnxuě 痰火點雪 (KR3eh040, 4 juǎn; alternative title Hónglú diǎnxuě 紅爐點雪) — a systematic treatise on tánhuǒ 痰火, the late-Míng Dānxī-school complex of phlegm-fire pathologies underlying láozhài 癆瘵 (consumption), coughing of blood, night-sweats, and cognate wasting syndromes. The work was widely re-edited in Qing and Edo Japan, and is one of the most-cited Ming sources in the post-Tāi-píng xūláo and láozhài literature.
