Advances in studies on modification technology of traditional Chinese medicine powders / 中国中药杂志

ABSTRACT

Most of the traditional Chinese medicine (TCM) powders showed bad physical properties, such as poor flowability, high hygroscopicity, agglomeration and poor wettability, which will affect the production process and even the efficacy of Chinese materia medica preparations. The exact characterization of the physical properties of TCM powders and the reshaping technology become the key to improve the quality and efficacy of Chinese materia medica preparations and to promote the modernization process of TCM. This article summarizes the evaluation methods of the physical properties and the modification technology of TCM powders, in order to solve the problems existing in the research and production of Chinese materia medica preparations, and to achieve the quality control of drugs and modernization of dosage forms.
