Yáng Yàozǔ 楊耀祖 (fl. late 17th c., 清), native of Tàiyuán 太原. Served as zhī Hújiāng wèi (commander at Hújiāng) and wrote one of the 康熙己未 (1679) prefaces to 蔣介繁’s Běncǎo zéyào gāngmù 本草擇要綱目 (KR3ec057), praising the work as “concise but comprehensive, clear but apt, careful and exact yet simply systematic” — the very book he had himself wished to compile. No further biographical detail securely attested; no CBDB record.
