Extracted by distillation from the wood of this evergreen tree, Camphor oil is a 100% pure, natural and undiluted essential oil. White Camphor is safe for aromatherapy use as it contains no safrol. White Camphor should still, however, be treated with caution and used in moderation. Camphor is a traditional ingredient of mothballs and these can be made at home by adding 10 drops of White Camphor to a cotton wool ball and placing these in cupboards, drawers, etc.
