Aromatherapy, also known as essential oil therapy, uses oils extracted from plants for a holistic approach to healing the mind, body, and spirit.
Odors take a direct route to the limbic system, which is the part of the brain related to emotion and memory, meaning that the use of aromas to moderate emotion can be quite effective. The impact of odors on the brain is why aromatherapy is recommended for anxiety sufferers to promote relaxation via olfactory therapy.
