Lán Mào 蘭茂 (zì Tíngxiù 廷秀, hào Zhǐ’ān 止庵, 1397–1476), native of Sōnghuájiāng 嵩明 (modern Sōngmíng, north of Kūnmíng) in Yúnnán. Hàn family relocated to Yúnnán in the Hóngwǔ era as part of the Míng settlement-army of the southwest. He took the jǔrén exam unsuccessfully, retired to a hermitage at Zhǐ’ān, and devoted his life to medicine and pharmacology.
His principal scholarly contributions are the Diānnán běncǎo 滇南本草 (KR3ec020) — the first major regional pharmacopoeia in Chinese history and the foundational text of Yúnnán ethnobotanical pharmacology — and the Yīnyùn yī kòu 韻略易通 (1442), a Míng-era phonological work systematising the rhymes of the yīnyùn xuē tradition. His other works include a respiratory-medicine manual Xìnglín yào yào 醒嗽藥要 and a literary collection Zhǐ’ān shī wén jí 止庵詩文集.
