Sloan's Liniment (at right) was once a popular over-the-counter drug store item.
Liniment (or embrocation), from the Latinlinere, to anoint, is a medicated topical preparation for application to the skin. Sometimes called balms, liniments are of a similar or lesser viscosity than lotions and are rubbed in to create friction, unlike lotions, ointments or creams.
Liniments are commonly used on horses following exercise, applied either by rubbing on full-strength, especially on the legs; or applied in a diluted form, usually added to a bucket of water and sponged on the body. They are also useful in hot weather to help cool down a horse after working, the alcohol cooling through rapid evaporation, and counterirritant oils dilating capillaries in the skin, increasing the amount of blood releasing heat from the body.
