Menthol is an organic compound found naturally in peppermint and other mint oils. Manufacturers refine it into crystals or liquid for topical and aromatic products. You will see it in chest rubs, lozenges, and topical analgesic creams.
Applied to the skin, menthol delivers a temporary cooling or distracting sensation that can soothe minor muscle aches. Inhaling menthol vapors creates a temporary feeling of nasal decongestion.
Watch for skin irritation or allergic reactions. Swallowing large amounts can be toxic for young children. Keep menthol products off broken or irritated skin. Talk to a healthcare provider before using menthol on infants or young children.
