PURPOSE:To obtain a SHIUN-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 SHIUN-KO composition composed of 1,000pts. of sesame oil, 200-450pts. of beeswax, 15-35pts. of lard, 50-130pts. of TOKI (root of Angelica acutiloba) and 90-130pts. of SHIKON (root of Lithospermum erythrorhizon) is compounded to a poultice base agent containing, as essential components, one or more kinds of materials selected from hydrophilic polymer (e.g. CMC-Na or sodium polyacrylate), 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 SHIUN-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. |
