Treatise on Cold Damage and Miscellaneous Diseases is a classic masterpiece of traditional Chinese medicine authored by the renowned physician Zhang Zhongjing in the late Eastern Han dynasty. It is also the first clinical medical monograph in Chinese medical history to comprehensively cover principles, methods, prescriptions, and medicinals. Against the backdrop of frequent warfare and rampant epidemics during the late Eastern Han, Zhang Zhongjing "diligently sought ancient teachings and extensively gathered various prescriptions," integrating his own clinical experience to complete this work after years of effort. This book perfectly combines the theory of Chinese medicine with clinical practice, earning it the posthumous title of "Ancestor of Prescription Works" and the origin of clinical pattern differentiation and treatment.
Due to historical changes and wars, the original text was once scattered and lost. Later, Wang Shuhe, the Imperial Physician of the Western Jin dynasty, collected and organized it, dividing it into two parts: the Treatise on Cold Damage and the Essentials from the Golden Cabinet, which have been passed down to the world. The Treatise on Cold Damage primarily discusses the occurrence, development patterns, and treatment methods of externally contracted febrile diseases (i.e., "cold damage"), while the Essentials from the Golden Cabinet focuses on the diagnosis and treatment of internal miscellaneous diseases. During the Song dynasty, Lin Yi, Sun Qi, and others undertook a national-level collation and printing of this work, establishing it as an authoritative text required for reading by physicians of all generations.
In the Treatise on Cold Damage, Zhang Zhongjing creatively proposed the theoretical system of "six-channel pattern differentiation." He categorized the various manifestations during the progression of externally contracted diseases into six distinct stages: Taiyang, Yangming, Shaoyang, Taiyin, Shaoyin, and Jueyin. This system not only reveals the transmission patterns of external pathogens invading the human body but also establishes corresponding treatment principles and classic formulas. For example, Cinnamon Twig Decoction, Ephedra Decoction, White Tiger Decoction, and Order the Qi Decoction—these formulas are meticulously composed and have proven therapeutic effects, remaining among the most commonly used "classic formulas" in clinical Chinese medicine to this day.
The Essentials from the Golden Cabinet, based on the theory of zang-fu organs and channels, systematically categorizes and discusses over forty types of internal miscellaneous diseases, gynecological conditions, and surgical emergencies. The book pioneered the "combined disease and pattern differentiation" model, using disease names as the guiding framework while integrating pulse manifestations and symptoms for pattern identification. The numerous formulas it contains, such as Golden Cabinet Kidney Qi Pill, Sour Jujube Decoction, and Major Bupleurum Decoction, not only reflect Zhang Zhongjing's exceptional skill in formula composition but also provide valuable experience for treating internal and gynecological diseases in later generations.
The influence of the Treatise on Cold Damage and Miscellaneous Diseases transcends time and national boundaries. The principle of pattern differentiation and treatment it established is the soul of clinical Chinese medicine; the hundreds of classic formulas it records form the core framework of formulary studies. Physicians of subsequent generations, such as Sun Simiao and Li Shizhen, were profoundly influenced by it. Even in East Asian countries like Japan and Korea, the "Kampo medicine" developed from this work continues to flourish today. It stands as the greatest bridge for Chinese medicine to transition from theory to clinical practice.
