Abstract

The invention discloses an external-use plaster (liver-disease plaster) for treating liver diseases. The traditional Chinese medicine external-use plaster is prepared from medicinal extracts of radix curcumae, zedoary, myrrh, hoantchy roots, prunella vulgaris, cowherb seeds and medical subsidiary substances, wherein the medical subsidiary substances comprise styrene-isoprene-styrene copolymer (SIS), tackifier, plasticizer, filler, permeation promoting agents and the like. The invention also discloses a method for preparing the liver-disease plaster. The method adopts supercritical extraction combined with alcohol extraction, and comprises the steps of using SIS hot melt adhesive and other subsidiary substances to prepare a matrix and spreading mixed medicine so as to form a resin-type external-use plaster. As the method adopts the novel medicine subsidiary substances and a novel preparation formulation technique, the plaster has the advantages of good skin adhesion, adhesive force, pharmaceutical transdermal absorptivity and good effects of easing lateral thorax pain and hepatosplenomegaly to patients suffering from liver-depression blood-stasis type liver diseases, is convenient to use, can be repeatedly pasted, and can meet the demand of modern medical treatment better.
