Are aromatherapy diffuser blends regulated by the FDA in the United States?

Aromatherapy diffuser blends sold purely as room fragrance are generally not regulated by the FDA as cosmetics or drugs, provided no therapeutic claims are made on the label. However, if your label claims the blend treats, cures, or prevents any condition, the FDA may classify it as a drug.
