Heat rub
From Wikipedia, the free encyclopedia
Heat rub is the name for a variety of products intended to relieve the pain of fibrositis, lumbago and muscular aches and strains. They are so named because they produce a feeling of warmth within the muscle of the area they are applied to.
Active ingredients are typically Menthol and Methyl Salicylate[1], and well-known brands are IcyHot in the United States, Deep Heat in the United Kingdom, Australia and other areas, and Tiger Balm in Asia. Typically heat rubs are applied in cream form, but patches,sticks and spray are also available.
