A mustard plaster is a poultice of mustard seed powder spread inside a protective dressing and applied to the body to stimulate healing. It can be used to warm muscle tissues and for chronic aches and pains. It was once part of conventional medical treatment, and available in prepared versions in pharmacies. It fell from favor in the 20th century and is now only used as a home remedy.
