 Unlike earlier texts like "Recipes for Fifty-Two Ailments", which was excavated in the 1970s from a tomb that had been sealed in 168 BCE, the "Inner Canon" rejected the influence of spirits and the use of magic.It was also one of the first books in which the cosmological doctrines of Yinyang and the Five Phases were brought to a mature synthesis.The "Treatise on Cold Damage Disorders and Miscellaneous Illnesses (Shang Han Lun)" was collated by Zhang Zhongjing sometime between 196 and 220 CE; at the end of the Han dynasty.
