黄帝
Huangdi Neijing (), literally the Inner Canon of the Yellow Emperor or Esoteric Scripture of the Yellow Emperor, 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.
