Huang Yuanyu (1705–1758), courtesy name Yulu, style name Yuanyu, and pseudonym Yannong, was a native of Changyi County, Weifang, Shandong. He was a renowned medical scholar in the early Qing dynasty. Initially a scholar, he lost his left eye due to a misdiagnosis by an incompetent physician, which spurred him to dedicate himself to the study of medicine. Huang spent his life practicing medicine and writing medical treatises. Eleven of his medical works, totaling 98 volumes, are recorded in the "Draft History of Qing." Among these, the most notable are "Su Ling Wei Yun," "Si Sheng Xin Yuan," "Changsha Yaojie," "Cold-Damage Disease Theory," "Yu Jiu Yao Jie," "Cold-Damage Disease Xuan Jie," "Jin Kui Xuan Jie," and "Si Sheng Xuan Jie," collectively known as the "Eight Medical Books of Huang." He also delved deeply into the study of the "Book of Changes," authoring "Zhou Yi Xuan Jie." His medical works were transmitted to Japan, Korea, and Southeast Asian countries during the late Qing dynasty. Huang's medical philosophy emphasized "supporting yang and suppressing yin" to cure diseases and prolong life, as well as prioritizing warmth and yang, establishing a unique school of thought in medicine.
