A POULTICE is a soft, moist mass of material applied to inflamed areas of the body to reduce swelling and inflammation. It is usually made from a combination of herbs, clay, and other ingredients that are mixed with water or oil to form a paste. The POULTICE is then applied directly to the skin and left in place for a period of time before being removed. Poultices have been used for centuries to treat a variety of ailments, including skin infections, muscle aches, and joint pain.
