Analgesic liniment is a preparation designed to be applied topically to the skin. It contains compounds that reduce pain and may also address inflammation. Many drugstores stock analgesic liniment, and this product is also available from pet supply stores for use on animals. Liniments designed for veterinary use should not be applied to people as they can be stronger and may contain irritants that could cause skin blistering, inflammation, and other problems.
Liniments range in texture from lotion-like preparations to thick, greasy balms. These products are designed to be rubbed into the skin and often have a strong odor. Sometimes the scent is the result of compounds like peppermint that have an analgesic effect, and in other products the scent is added because consumers expect liniments to smell strong. Some people find the sharp smell irritating, and it is possible to find unscented products.
Analgesic liniments can be used to address inflammation, aches, and pains such as strained muscles. These products may be used by athletes and other people who have overworked or developed strains in their muscles. Application of liniment may be followed with a supporting bandage in the treatment of issues such as wrist and ankle sprains. Some people also use liniments in the treatment of coughs and colds, applying the compound to the chest.
These products should be used with care. A strong analgesic liniment can essentially act as a topical anesthetic. While this can indeed reduce pain and soreness, it may cover up symptoms that require medical attention.
In addition, some very strong products may blister or irritate the skin. Someone using a liniment for the first time may want to test with a small dab on the sensitive skin of the inner elbow to determine whether or not the analgesic liniment will irritate the skin. People with allergies should read ingredient lists carefully as liniments contain variable ingredients and can sometimes include allergens.
In veterinary care, liniment is most commonly used on horses. Liniments can be applied to sore legs and may also be used when a horse is being washed and rubbed down after exercise to help the horse cool down. Products designed for horses may be intended for use in dilute form and the directions on the container should be read carefully. Horses can also have reactions to analgesic liniment, and it is advisable to test a product before liberally applying it, especially if it will be used under wraps or a horse blanket.
