Students of acupuncture and Chinese medicine recognize Zhang Zhongjing as the author of two seminal texts, that are among the most influential in Chinese medical history: the Treatise on Cold Damage Disorders (Sh?ng Han Lun, ?寒?) and Essential Prescriptions from the Golden Cabinet (J?n Gui Yao Lue, 金?要略). However, what is less well-known is that Zhang Zhongjing authored several other texts, all of which were lost over time, with the sole exception of the Treatise on the Five Zang Organs (W? Zang Lun, 五藏?). This was discovered in 1900 in a hidden library of China’s Mogao Caves of Dunhuang by a Taoist priest named Wang Yuanlu.
