Wellness Tip posted by Mystic Mix. Use natural Spritzers for air fresheners, instead of synthetic products. Mystic Mix uses only 100% therapeutic grade essential oils for Mystic Creations Spritzers. If you make your own, use only therapeutic grade to get the full benefit of the essential oils. For more information check out Sarah Dobson’s (Certified Family and Nutritional Herbalist) informative article on air fresheners.
