All of our Essential Oils are completely natural. Every oil is 100% pure, with exception of our 10% blends, which are diluted with an all-natural, unscented safflower oil. Use these in your spa or resort to scent your massage oils and lotions, aromatherapy, or in a diffuser to help create a soothing atmosphere. With over 10 oils available in the 4 oz bottles, you are sure to not only find what you want, but ensure that your spa or resort is well stocked.
