The Shanghan Lun (simplified Chinese: 伤寒论; traditional Chinese: 傷寒論; pinyin: Shānghán lùn) or Shanghan Zabing Lun (simplified Chinese: 伤寒杂病论; traditional Chinese: 傷寒雜病論; pinyin: Shānghán zábìng lùn), known in English as the Treatise on Cold Damage Disorders or the Treatise on Cold Injury, is a Chinese medical treatise that was compiled by Zhang Zhongjing sometime before the year 220, at the end of the Han dynasty. It is amongst the oldest complete clinical textbooks in the world (cf. Carakasaṃhitā and the Hippocratic Corpus), and one of the four canonical works that students must study in traditional Chinese medical education today.

The Shanghan Lun has 398 sections with 113 herbal prescriptions, organised into the Six Divisions corresponding to the six stages of disease:[1]
