Research progress on Chinese materia medica gel plaster and its application in product development / 中草药

ABSTRACT

As an important part of transdermal drug delivery system, gel plaster of Chinese materia medica (CMM) has inherited the traditional theory of traditional Chinese medicine and developed rapidly in recent years in combination with the new technology and technology of modern preparations. Compared with the traditional black paste and rubber paste, the gel plaster of CMM, which uses water-soluble polymer as the matrix, has the advantages of good moisturizing performance, good compatibility with the skin, and repeated patching. It has been paid more and more attention by researchers. At the same time, the gel plaster of CMM also faces many problems, such as unreasonable matrix ratio, simple preparation process, and imperfect quality evaluation system. This article reviews the development status, matrix composition, and preparation technology of gel plaster of CMM in recent years, and provides reference for the further study of gel plaster of CMM.
