【1】Project background
Chinese medicine culture is one of the cultural treasures of our country. It has the advantages of good curative effect and less side effects. Compared with western medicine, all-natural Chinese medicine also has the characteristics of treating both symptoms and root causes. It can not only be used to treat diseases, but also to regulate the body of patients. Therefore, it is especially sought after by people who have been pursuing quality of life today."

These factors are very unfavorable to the development of traditional Chinese medicine. Therefore, with the increasing demand for traditional Chinese medicine, a new dispensing method using small-package decoction pieces of traditional Chinese medicine appeared.

Small package of Chinese medicine decoction pieces package is to pack each kind of traditional Chinese medicine into small packages with fixed specifications, so that when dispensing the medicine, it is only necessary to directly count the number of decoction pieces packages, which saves the time of weighing and greatly improves the efficiency of dispensing. The use of large and medium-sized traditional Chinese medicine hospitals provides an opportunity.
