Aromatherapy is a common term associated with the theory that essential oils support the human body† from a physiological perspective when they are added to various mediums and applied to the body or when their aromatics are inhaled. The application of such mediums are then used by professionally trained therapists either in private practice or by those who practice at complementary health care clinics and at spas.
Physiological is a branch of science related to the function of a living organism related to that organism's structure, their organs and systems.
There is an enormous amount of literature available in hard-copy print and via online sources that make reference to the health benefits of using essential oils. Pease be advised that SOME information is GOOD and is supported by empirical research. However, please be cognizant, that many references online are simply marketing ploys luring the reader into believing that essential oils play a vital role in health care, or that a particular brand of essential oils are better or more therapeutic.
Aromachology relates to the study of odours on human behaviour from a psychological perspective and was coined in 1989 by the Sense of Smell Institute a division of the Fragrance Foundation. Scent preference is a very subjective experience. Aromatics that occur in our natural world and in fragrances that are designed by perfumers and scent chemists (regardless if the composition contains natural or synthetic essences) are appealing to different folks for different reasons. When a scent is detected by the olfactory system that is appealing it can elicit a positive response such as relaxation, exhilaration, happiness, and well-being.†
Psychological is a branch of science related to the development of human personality, behavioural traits, the emotional and mental state of humans and their reactions and coping strategies (or lack thereof) in relation to their everyday experiences.
