Líng Huàn 凌奐 (1822–1893), zì Xiǎowǔ 曉五, hào Zhégōng Lǎorén 折肱老人 (“Old Man with the Broken Arm” — a reference to the Zuǒzhuàn’s “三折肱知為良醫” maxim). Native of Guī’ān 歸安 (Húzhōu, Zhèjiāng). Late-Qīng wēnbìng 溫病 (epidemic-warmth) physician — he was a leading second-generation pupil of the Húzhōu school descended from Wáng Jǐnsān 王晉三 and a contemporary of Wáng Shìxióng 王士雄. His Běncǎo hài lì 本草害利 (KR3ec059) is the most distinctive late-Qīng pharmacopoeia in that it organises each substance entry around the contraindications and harms of the drug (“害”) followed only secondarily by the benefits (“利”). The work reflects a pessimistic clinical realism characteristic of the wēnbìng school after the great mid-19th-c. epidemics. Not in CBDB.
