Witches came into being and developed gradually in the formation of clan society. As a social development, it has the significance of progress. Witch doctors not only use witchcraft to treat people's diseases, but also master certain medical techniques and drugs to relieve people's suffering. Of course, their historical role cannot be completely denied. However, history must not go backwards, and we should take the witch who came later as the origin of medicine, rather than using the existing medical knowledge. Witches have contributed to the development of medicine, but they are by no means creators or inventors of medical knowledge. We should not confuse our sight just because witchcraft and witchcraft prevailed in the late primitive society and slave society. China's medicine originated from the experience accumulated by people in the primitive society of China in seeking food, improving their clothes and living conditions, seeking health and eliminating diseases, rather than from the enlightenment of asking god and ghosts.
