The horse liniment is a veterinary composition for topical application for the relief of muscle and joint pain in horses. The composition contains, by weight, about 49% alcohol, 20% olive oil, 10% arnica, 14% creosote, 1% iodine, 2% turpentine, 2% camphor, and 2% alum. The ingredients may be mixed at room temperature, the powdered ingredients being soluble in the alcohol-olive oil base. The composition is applied topically to the affected muscles or joints in conventional manner as needed. The composition has been found to be effective, often with a single application, with increased range of motion, an absence or reduction of limping, increased energy, and other signs of a healthy, active horse.
