Magnesium salicylate, C14H10MgO6), is a common analgesic and non-steroidal anti-inflammatory drug (NSAID) used to treat mild to moderate muscular pain. It is also used to treat headaches, general back pain, and certain joint pains like arthritis.
It is found in a variety of over-the-counter (OTC) medications as an anti-inflammatory, primarily for back-pain relief. Magnesium salicylate can be an effective OTC alternative to prescription NSAIDs, with both anti-inflammatory and pain-relieving effects.
