The physicochemical properties of TCM powders are very complex and often exist in the form of amorphous powders, resulting in significant differences in physical properties such as viscosity, fluidity, wettability and compressibility between TCM powders and chemical raw materials. Chemosynthetic drugs have a single component, and the interaction between various substances is relatively small, and the interaction is far less than that of traditional Chinese medicine powder. Compared with chemical drugs, traditional Chinese medicine powder has more dosage and less excipients, and its role in medicine is far greater than that of chemical drugs. Therefore, it is of great significance to study the modification technology and equipment which accord with the characteristics of traditional Chinese medicine powder.

Chinese medicine powder modification technology started late, mainly from the chemical industry and other related industries for reference. Therefore, the basic research is relatively weak, and the modification mechanism is not very clear. The research direction of the modification technology of traditional Chinese medicine powder in the future is mainly to further study the principle of the modification of traditional Chinese medicine powder, optimize the modification process of traditional Chinese medicine powder, develop the surface modifier and high-performance modification equipment which accord with the characteristics of traditional Chinese medicine powder, and characterization method is also an important link in the modification technology of traditional Chinese medicine. A special characterization method for modified powder of Chinese medicine.

Chemosynthetic drugs have a single component, and the interaction between various substances is relatively small, and the interaction is far less than that of traditional Chinese medicine powder. Compared with chemical drugs, the dosage of traditional Chinese medicine powder is large, the excipients are few, and the role of traditional Chinese medicine in medicine is far greater than the role of raw materials in chemical drugs.
