Mustard plaster

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.[1] 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.[2]

How it works

An enzymatic reaction in the wet mustard powder produces a chemical called allyl isothiocyanate, 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

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

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