Treatise on Cold Damage and Miscellaneous Diseases stands as the world's first empirical clinical medical compendium and represented the pinnacle of medical knowledge in its era. Avicenna's Canon of Medicine, a seminal work in Islamic medicine, emerged over 700 years later. Its author, Zhang Zhongjing (also known as Zhang Ji), was a renowned physician of the Han Dynasty hailing from Nanyang Commandery. He was recommended for his filial piety and integrity, eventually rising to the position of Governor of Changsha.
It is said that during Emperor Xian's reign, a typhoid epidemic ravaged the Zhang clan, claiming two-thirds of its members within a decade. Determined to address this crisis, Zhang Zhongjing resolved to study medicine under Zhang Bozu. Through relentless dedication, he surpassed his mentor, becoming the most accomplished and unrivaled clinical physician of the Han Dynasty. Posterity unanimously venerates him as the "Sage of Medicine."After years of dedicated research and drawing upon his extensive clinical experience, Zhang Zhongjing authored a groundbreaking clinical medical masterpiece—Treatise on Cold Damage and Miscellaneous Diseases.This work systematically analyzes the etiology, symptoms, progression, and treatment approaches for exogenous febrile diseases (including various epidemics). It innovatively proposes therapeutic principles tailored to the depth and complexity of different conditions, categorizing disorders into six major patterns (known as the "Six Meridian Differentiation").
The text features 113 representative formulas and 397 therapeutic methods. These theories and prescriptions have remained the classic reference for subsequent generations of scholars, leading later practitioners to designate Zhang Zhongjing's formulas as "classical formulas" and universally recognize him as the "Father of Classical Formulas."
The Treatise on Cold Damage and Miscellaneous Diseases stands as an outstanding legacy in China's medical treasure trove and the most influential work in the history of Chinese medicine. Ancient and modern physicians alike hold it in the highest regard. Many diagnostic and therapeutic principles in traditional Chinese medicine still draw guidance from theories pioneered in this text. Consequently, it remains a required course for undergraduate students in Chinese medicine.
