PURPOSE:The titled plaster having high remedying effect on trauma, burn, etc. with a very small amount of it used free from contamination with dyestuff, by setting a fibrous material layer keeping a shikonin-containing mixture at the central part of one face of a film piece, laying a pressure-sensitive adhesive high polymer substance at the peripheral part. CONSTITUTION:A fibrous material layer keeping a shikonin-containing mixture comprising shikonin or an extract of Lithospermi Radix, etc. is set at the central part of one face of a film (e.g., paper, cloth, etc.) piece, and a pressure-sensitive adhesive layer is laid at the peripheral part, to give a plaster for remedying skin diseases. Shikonin is a naphthoquinone compound shown by the formula contained in Lithospermi Radix, etc. It has been used as a remedy for skin diseases by its medicinal action such as anti-inflammatory, hemostatic, analgesic action, etc., but it has demerits such as contamination with dyestuff, low utility efficiency, etc. Meanwhile, the titled plaster can make remedying effect maximum even if a very small amount of expensive shikonin or extract of Lithospermi Radix is used.
