Menthol activates TRPM8, the same cold-sensing receptor triggered by a cool breeze, producing a cooling sensation that competes with pain signals (a "counterirritant"/gate-control effect) and may have mild local effects on blood flow and κ-opioid receptors. The relief is largely symptomatic and short-lived rather than disease-modifying.
Evidence is emerging and modest. In a randomised trial, adding levomenthol to ibuprofen gel produced faster pain relief and a lasting cooling sensation versus ibuprofen alone for soft-tissue injuries, and menthol gels are widely used by physical therapists for sore muscles and minor arthritis. A separate ankle-sprain trial found a diclofenac/menthol combination no better than diclofenac alone — so menthol's main value is the immediate cooling comfort it adds. It is NSAID-free, a reasonable choice when avoiding systemic drug exposure.
Peer-reviewed studies on the active compound — citations link to PubMed.
“Both ibuprofen/levomenthol and diclofenac gels provided superior global pain relief compared with ibuprofen gel, with a shorter median time to significant pain relief. Only ibuprofen/levomenthol gel provided cooling for up to 2 hours.”
“No significant improvement was observed with topical 1% diclofenac/3% menthol gel compared with placebo, 1% diclofenac, or 3% menthol gel in treating pain from ankle sprain.”
