Cinnamomum camphora/China, Japan/Wood. The crude essential oil distilled from the wood of camphor trees contains 35 to 40% camphor along with the potentially carcinogenic constituent safrol. Crude camphor oil is re-distilled to remove the safrol and produce white camphor. White is the grade preferred in scenting detergents, soaps, disinfectants, deodorants, room sprays and other household products. Aromatherapy benefits: clarifying, energizing, purifying.
