What is the relationship between traditional Chinese medicine and witchcraft in ancient times?

The earliest medicine belongs to witch doctors, and Zhouyi was written from the perspective of divination, which also contains rich medical thoughts. Although witch doctors are superstitious, the methods of praying for blessings and practicing medicine have made great progress compared with the original instinctive medical activities. During the Spring and Autumn Period and the Warring States Period, witches and doctors separated due to the improvement of social productivity. Its symbol is that one of the "six incurable diseases" put forward by Bian Que is "believing in witches but not doctors". It can be said that Bian Que was the first person to separate witch doctors in the history of China.
