Wu Yi-luo (circa 1704-1766), styled Zuncheng, was a native of Ganpu. He was a scholar. His ancestors had a rich collection of books, including many rare medical texts from across the country. In his youth, he studied for the imperial examinations while also reading medical texts, later shifting his focus entirely to medicine. He traveled to Hubei, Guangdong, Hebei, Henan, and other regions, and spent five years in Siming (present-day Ningbo), where he immersed himself in medical texts at the Tianyi Pavilion, greatly refining his knowledge. He practiced medicine for 40 years and gained fame in his hometown. He authored Materia Medica from the New, in which he revised and expanded on the errors in Wang Ang's Bencao Beiyao, adding nearly 300 new medicinal herbs, including Chinese Caterpillar Fungus and Heterophylly Falsestarwort Root, which were first documented in this book. His annotations on medicinal properties introduced many novel insights. Chengfang Qieyong records over 1,300 contemporary prescriptions, explaining their principles and detailing modifications. It was highly valued by physicians for clinical practice. The appendix, Wuyao Yuanquan, contains 74 entries on disease prevention and health preservation. Cold-Damage Disease by Meridians provides detailed annotations on the Cold-Damage Disease Treatise, elucidating its deeper meanings. He also wrote One Source Must Be Thorough, Four Examinations Must Be Detailed, Regulations on Miscellaneous Diseases, Gynaecology for Today, Commentary on the Zhouyi, and Interpretations of the Spring and Autumn Annals, among others, most of which are now lost. His disciple, Xu Zai, a native of Haiyan, continued his work. Xu was also skilled in poetry and prose. He authored Summary Songs of Ancient and Modern Famous Prescriptions, Treatise on Internal Injury from Overexertion, Medical Cases of the Extraordinary, Discourse on Dysentery, and Discourse on the Golden Chamber, none of which are extant today.
