PURPOSE:To provide a gel plate having excellent strength and useful especially as a base of a poultice, by dispersing a polysaccharide such as carrageenan in an aqueous solution of a polyhydric alcohol. CONSTITUTION:A polysaccharide or its derivative having gelling power (including a material developing the gelling power by the synergistic action with another material, e.g. a combination of guar gum and a boron compound, etc.), preferably carrageenan or a mixture of >=20% carrageenan and other polysaccharides is dispersed in an aqueous solution of a polyhydric alcohol (e.g. sorbit, glucose, etc.) containing water and the alcohol at a ratio of 95:5-40:60. If necessary, a third component is added to the dispersion, and the dispersion is heated to obtain a homogeneous solution. The solution is, if necessary after addition of a drug component, extruded through a slit or cast in the form of a flat plate, which is cooled to obtain the objective gel plate.
