The quality of your aromatherapy experience is only as good as the quality of your essential oils: because the aromatherapy market is unregulated in the United States, many companies who claim to sell "pure" essential oils are actually adulterating their oils by adding chemicals or mixing several varieties of oils together to save money. With Auroma, you can rest assured that their essential oils are rigorously tested for their purity and authenticity. In fact, they are the only US supplier of essential oils that are certified by the Therapeutic Goods Administration of Australia (Australia's regulatory agency for medical products).
