Taoism is closely related to traditional Chinese medicine. First of all, both theories originated from the Book of Changes. Taoism is the Tao Te Ching, and doctors are the Huangdi Neijing. Among many schools of traditional Chinese medicine, Taoist priests who study medical skills occupy an absolute majority. Taoism has also made outstanding contributions to the development of Chinese medicine, because Taoism does not pursue material wealth, and Taoist doctors can often study medical skills to a higher level, including the production and application of pills, including the Yellow Emperor. The influence of Taoism is very important in the collation of classics such as Neijing and Prescription. The qigong or internal strength practiced by Taoist people is in the same strain as the health-preserving methods created by Chinese medicine. The pursuit of immortality by the immortals, the largest school of Chinese medicine, provides a broader and more peculiar means of diagnosis and treatment for Chinese medicine in this way. It can be said that without Taoism, the development of Chinese medicine will be greatly weakened, and Chinese medicine is used by Taoism, which provides great support for Taoist health care and diagnosis.
