Aromatherapy is the use of essential oils to support physical health and well-being. Essential oils carry biologically active volatile compounds of flowers and plants in a highly concentrated form. They are, in many ways, the essence of the plant and can provide therapeutic benefits in very small amounts.
The particles in essential oils, which come from flowers, twigs, leaves, or bark, can be inhaled, prompting various beneficial effects. As noted by the National Association for Holistic Aromatherapy (NAHA):
"It [Aromatherapy] seeks to unify physiological, psychological and spiritual processes to enhance an individual's innate healing process."
There are about as many uses for aromatherapy as there are essential oils, but one of the most exciting areas of research is for anxiety, with research showing essential oils may help relieve symptoms without the side effects of anxiety drugs.
