Aromatherapy is the systematic use of volatile plant oils known as essential oils for the treatment or prevention of disease. It is a form of complementary therapy designed to treat the whole person and not just the symptom or disease by assisting the body's natural ability to balance, regulate, heal and maintain itself.

Essential oils consist of tiny aromatic molecules that are readily absorbed via the skin, and whilst breathing they enter the lungs. These therapeutic constituents next enter the bloodstream and are carried around the body where they can deliver their beneficial healing powers. Because they are highly concentrated, only a small quantity of essential oil is required to bring about results.
