Huangdi Neijing (simplified Chinese: 黄帝内经; traditional Chinese: 黃帝內經; pinyin: Huángdì Nèijīng), literally The Yellow Emperor 's Internal Canon, is an ancient Chinese medical text that has been treated as the fundamental doctrinal source for Chinese medicine for more than two millennia. The work is composed of two texts—each of eighty-one chapters or treatises in a question-and-answer format between the mythical Yellow Emperor and six of his equally legendary ministers.

The book provides a ancient view on human health and body in China.
