Research progress on selection of matrix and adding methods of volatile oil in Chinese materia medica cataplasma / 中草药

ABSTRACT

Cataplasma is a new transdermal drug delivery carrier, playing a significant role in the modernization of Chinese materia medica (CMM). It can overcome many shortcomings such as inconvenient use and intense irritation in traditional adhesive plaster and black plaster. However, the development of cataplasma is restricted by some crucial factors like the types of auxiliary materials and the processing ways of volatile medicine. A total of 254 articles related to CMM cataplasma optimization and the volatile oil treatment published from 2000 to 2017 were collected and sorted in this paper. The matrix types and excipients ratio scope, the experiment design method of optimized ratio of base material, and the processing ways of volatile oil in cataplasma were summarized, and then the existing problems in these three aspects mentioned above were discussed with view to giving reference for follow-up studies.
