<unk> 's best-known use is as a topical antiseptic to treat minor wounds, burns, and scratches. It is also used in the antisepsis of the umbilical cord and the antisepsis of wounds with inhibited scar formation, such as neuropathic ulcers and diabetic foot sores. When applied on a wound, it stains the skin a distinctive carmine red, which can persist through repeated washings. Due to its persistence and to its lethality to bacteria as an antiseptic,<unk>  is useful on infections of the fingernail or toenail. The U.S. Food and Drug Administration in 1998 classified<unk>  as not generally recognized as safe due to a lack of recent studies and updated supporting information. In the United States, its use has thus been superseded by other agents (e.g., povidone iodine, benzalkonium chloride, chloroxylenol).
