[0002] With the development of the economy and society and the development of the traditional Chinese medicine industry, people pay more and more attention to the role of traditional Chinese medicine in regulating the body. The development of modern pharmaceutical technology has also enabled traditional Chinese medicine decoctions to be made into medicines and tablets, which not only saves patients time in boiling medicine, but also makes it easier to carry and take, which has a positive effect on the development of traditional Chinese medicine.
