PURPOSE:To obtain a therapeutic material for external use, exhibiting strong initial cooling effect without lowering the drug action of aloe, and especially effective as a remedy for scald, by compounding aloe or aloe extract to a hydrophilic hydrous gel substrate, and forming the mixture in the form of a sheet. CONSTITUTION:Aloe or an aloe extract is compounded to a hydrophilic hydrated gel substrate containing 3-30wt% of a hydrophilic polymer and 10-95wt% of water, and the mixture is spread on a carrier and formed in the form of a sheet to obtain the objective material for external use. The hydrophilic polymer is selected from polyacrylic acid, acrylic acid copolymer, maleic anhydride copolymer, water-soluble polyamide, polyvinyl alcohol, etc., and the substrate is preferably incorporated further with a polyhydric alcohol to tackify the substrate and to increase the solubility during the preparation. The amount of aloe added to the material is preferably >=2% as aloe powder of 1-15% as aloe extract.
