Solid preparations account for more than 50% of traditional Chinese medicines(TCM). TCM powder is an important raw material for solid preparations of TCM. Its powder properties directly affect the quality of solid preparations, and even clinical safety and effectiveness. Particle design technology based on the characteristics of powder in TCM is an important means to improve and enhance the quality of solid preparations. This study summarized the relevant principles, methods, characteristics, classification, equipment, and other elements of particle design technology in recent years, analyzed the difficulties in its application in the field of TCM powder, and proposed the strategies in conjunction with the development of computer data mining. The present study is expected to provide a reference for the suitability of particle design in the field of TCM powder.
