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 50 oils available, you are sure to get exactly what you want for your spa.
