By definition Aromatherapy is the use of essential and plant oils in a massage or bath. We like to think of it as self care. Diffusing essential oils in a oil diffuser, is the best way to reap the benefits of the amazing properties of plant oils. We diffuse everyday, all day. 24/7. Diffusers are ultrasonic devices that help disperse the tiny particles into the air. We can't live without one.
