Aromatherapy works through inhalation and absorption.
Essential oils contain volatile compounds. Molecules that enter the nose or mouth pass to the lungs, and from there, to other parts of the body. As the molecules reach the brain, they affect our limbic system.
The molecules in the essential oils are small enough to allow them to penetrate through the skin. The skin near pulse points is thinner, hence the blood vessels are closer to the skin surface.
One of the most satisfactory aspect of using essential oils, is that they enter and leave the body with great efficiency, leaving no toxins behind.
How to use
Apply aromatherapy roll-ons at the pulse points.
To further accentuate the effect, inhale the blend from your skin or directly from the bottle.
