These Natalie Miller's Aromatherapy LLC blends are made with sustainably sourced organic essential oils for the most luxurious experience for you and for the health of the planet. Use in a variety of ways: in a diffuser, a couple drops in a bath, make your own body care products or aromatherapy rollers, in candle making, and more. Always dilute and heed the "Precautions" on the bottle. They are twice as potent as popular market brands so halve the oils in any recipe. 5mL.
