There are many ways to prepare raw materials for health foods. In recent years, there have been compositions of Chinese herbal medicines, and Chinese herbal medicines have been used in human health since ancient times. The ancients divided the Chinese herbal medicine into the upper medicine, the middle medicine, and the lower medicine. The upper medicine is used for human health care, and the middle and lower medicines are combined with the monarch, the minister, the sacrificial, and the medicine is used to treat the disease. "Shen Nong's Materia Medica" and "Compendium of Materia Medica" said: "The medicine is good for life, non-toxic, multi-service, long-term service does not hurt people. Want to be light and good, not old, and the scripture." Tao Hongjing, a famous doctor of the Southern Dynasties, said: "The top grade is medicinal, and it can also send disease. But the power and thickness are not quick-acting. The clothes will be greatly benefited by the years." Other Chinese herbal medicines generally have some toxicity. It can be seen that the ancients deeply used the essence of Chinese herbal medicine for human health and treatment.
