Substrate of traditional Chinese medicine cataplasm

Abstract

The invention discloses a substrate of a traditional Chinese medicine cataplasm, which is prepared by the following raw materials in parts by weight: 800-1000 parts of partially neutralized sodium polyacrylate, 600-800 parts of crosslinking povidone, 350-500 parts of polyvinylpyrrolidone, 25-50 parts of aluminum glycinate, 6-10 parts of edetate disodium, 4000-5000 parts of glycerol and 35-50 parts of L-tartaric acid. Experimental results indicate that the substrate of the traditional Chinese medicine cataplasm does not cause skin allergy, and is low in stimulation reaction and easy to peel; in a peeling process, a patient does not feel pain; no medicine is residual; the transdermal absorption of the medicine is high; a medicine effect is better; the patient can use the medicine conveniently; and an organic solvent is not used in a production process, so that the environment is not polluted. The substrate can be supported with a water-soluble effective ingredient and an oily effective ingredient clinically, and has a wider application range.
