Liniment, from the Latin linere, to anoint, is a medicinal preparation meant for external use, but one that is thinner in consistency than an ointment .
Liniments are typically sold to relieve pain and stiffness, such as from sore muscles or from arthritis. These liniments typically are formulated from alcohol, acetone, or similar quickly evaporating solvents, and contain counterirritant aromatic chemical compounds such as benzoin or capsaicin. Opodeldoc is a sort of liniment invented by the physician Paracelsus. Absorbine Jr. is a trade name for a brand of liniment widely sold in the United States.
