'SATOTSU-KO' POULTICE AND PREPARATION THEREOF

PURPOSE:To obtain a SATOTSU-KO (a compounded Chinese drug poultice) free from seepage of colored oily substance from the surface or back surface of the poultice, having excellent water-retainability, visco-elasticity, peelability and stability and having improved permeability of the principal drug component into the skin, by using a hydrophilic polymer, a natural rubber or a synthetic rubber as a base agent. CONSTITUTION:A SATOTSU-KO composition composed of 1,000pts. of sesame oil, 170-270pts. of beeswax, 50-70pts. of lard and 750-850pts. of bitumen is compounded to a plaster base containing one or more kinds of materials selected from hydrophilic polymer (e.g. sodium arginate or carrageenan), natural rubber or synthetic rubber which may be added with a surfactant. The compounded mixture is uniformly kneaded and the obtained plaster is spread on a supporting material to obtain the objective poultice. The amounts of the SATOTSU-KO composition, the hydrophilic polymer and the rubber component are preferably 5-50wt.%, 0.5-15wt.% and 2.0-25wt.% based on the whole plaster, respectively.
