The invention belongs to the technical field of plaster preparations, and relates to an external plaster for promoting blood circulation and relieving pain, which is prepared from borneol, camphor, a slow release agent, ligusticum wallichii fluid extract, peppermint oil, cinnamaldehyde, zinc oxide, vaseline, rosin, lanolin, liquid paraffin, a transdermal enhancer, a tackifier, a microemulsion, dimethyl sulfoxide and rubber, wherein the slow release agent is one of nano coconut shell activated carbon, silane coupling agent modified silicon micropowder or alpha-cyclodextrin. The active analgesic plaster for external use has very obvious effects of activating blood circulation and relieving pain, good transdermal absorption rate and quick response, the active ingredients in the plaster are not easy to volatilize, the plaster has good viscosity and uniform quality. Meanwhile, the components of the external plaster are easier to be absorbed by the skin by preparing the nano-scale emulsified slurry and then coating the adhesive. |
