Used topically to treat fungal infections of the skin and nails, such as athlete's foot, jock itch, ringworm, and onychomycosis. It works by inhibiting fungal growth through disruption of cell membrane integrity and interference with nutrient uptake. Also has anti-inflammatory and antimicrobial properties, making it effective in treating seborrheic dermatitis and certain bacterial skin infections. Commonly found in creams, gels, and nail lacquers for localized treatment.
