The U.S. FDA has established a maximum concentration limit of 11% for camphor in consumer products and discourages general medicinal use, except for specific skin-related applications like medicated powders where 'small amounts' are used. Products labeled as camphorated oil or liniment are generally banned, with an exception for 'white camphor essential oil' which contains negligible camphor. EWG Skin Deep identifies a high risk for allergies and immunotoxicity, along with moderate use restrictions, citing respiratory concerns if incorporated into inhalable forms.
