Mustard plaster

From Wikipedia, the free encyclopedia

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 to treat chronic aches and pains.[1] For long a part of conventional medical treatment, and available in prepared versions in pharmacies, it fell from favour in the 20th century, and is now only used as a home remedy.[2]

How it works[edit]

An enzymatic reaction in the wet mustard powder produces a chemical called allyl isothio-cyanate, which is absorbed through the skin as a transdermal drug.[2]

It provides warmth and functions as a counterirritant, meaning that it stimulates nerve endings in the skin and thereby distracts the body from deeper-seated pain.[1]

Uses[edit]

Mustard plasters were used for aches and pains, including rheumatism, arthritis, and sore muscles.[3] It was also used for chest congestion.[3]

Side effects[edit]

If left in place for too long, it can produce significant burns to the skin.[3]
