The Shanghan Lun (simplified Chinese: 伤寒论; traditional Chinese: 傷寒論; pinyin: Shānghán Lùn) is a part of Shanghan Zabing Lun (simplified Chinese: 伤寒杂病论; traditional Chinese: 傷寒雜病論; pinyin: Shānghán Zábìng Lùn), and also known in English as the Treatise on Cold Damage Diseases, Treatise on Cold Damage Disorders or the Treatise on Cold Injury. It is a Traditional Chinese medicine treatise that was compiled by Zhang Zhongjing sometime before 220 AD, at the end of the Han dynasty. It is amongst the oldest complete clinical textbooks in the world (cf. Carakasaṃhitā and the Hippocratic Corpus). It is considered one of the four canonical works of Traditional Chinese medicine, along with Huang Di Nei Jing, Jin Gui Yao Lue, and Wen Bing Xue.
- Song dynasty edition. Collated by scholastic ministers Gao Baohen, Lin Yi, and Sun Qi under the order of the emperor and published in 1065 AD. Reprinted in the Ming dynasty.
- Cheng Wuji's Annotated Treatise on Cold Damage. Extensively read in Japan and China, was widely circulated in Cheng's time. However, many transcriptions and re-transcriptions have stirred up disagreement as to whether it is true to the original.
- Classic of the Golden Chamber and Jade Sheath. This book has the same content as the Song edition with other minor variations in context.
- Kang Ping edition. Kang Ping is the name of the period from 1058 to 1068 AD in the Kōhei era in Japan. It is indispensable for study because it retained the ancient style of typesetting dated back to the era at the end of the Han dynasty.
The Song edition is organized into ten volumes including the first two chapters on pulse diagnosis; Cheng's edition is also organized into ten volumes but simplified; Classic of the Golden Chamber and Jade Sheath is organized into eight volumes.
The Shanghan Lun has 398 sections with 113 herbal prescriptions, organised into the Six Divisions corresponding to the six stages of disease:
