Abstract
A patch for facilitating blood circulation, including a warmer, a powder-containing bag and a base sheet. The warmer includes iron powder for generating heat oxidized by oxygen in the air and an oxidization regulatory agent enclosed in a flat, air permeable bag. The outer shape of the bag is larger than that of the warmer, and contains powder including components contained in bamboo vinegar or wood vinegar. The outer shape of a base sheet is larger than that of the bag, and the base sheet has an air ventilation hole at a central portion. An adhesive layer is formed on the surface of one side of the base sheet. The warmer and the powder-containing bag are sequentially adhered onto the adhesive layer to cover the air ventilation hole.
