The powder is mainly composed of clotrimazole which is an effective antifungal agent. Its very useful in the treatment of fungal infections, prickly heat, itching and irritation in the skin. Its applied as dusting powder over affected parts of the body. Its very effective and I have seen positive results when I had accidental foot injury and another injury to the eye. The powder acts by reducing the painful inflammation of the tissue and heals it within days.
