SleepSwag's Therapeutic Aromatherapy oil blends are uniquely formulated to support and enhance well-being using 100% pure therapeutic grade essential oils. Not all essential oils are created equal! Many essential oils on the market that claim to be therapeutic are note pure and some are toxic and dangerous if solvents are used during the extraction process which results in oils that contain impurities. SleepSwag uses essential oils that are exclusively created using either Steam Distillation or Cold Press Expression, they are then tested for purity and certified pure by our essential oil providers.
