Aromachologist is a person who practices aromachology, which is a method of using smells or essential oils to create, either in isolation or through blending in formulations, essential oils that have behavioral, physical and emotional benefits. Smell is the least studied of the senses, but aromachology is being used increasingly in healthcare and building science, and also in the world of sports and in practical matters such as real estate sales.
While all aromachologists have a refined sense of smell, some employ other senses including sight, sound and hearing. These are synesthetes and history documents famous synesthetes such as the British painter David Hockney, the Russian artist Wassily Kandinsky, the Hungarian composer Franz Liszt and the English poet William Blake.
An aromachologist is a person who studies the effects of fragrance on human psychology and behavior and works with essential oils for their positive effects on behavior and feeling. An aromachologist is a practitioner of aromachology, which is a term coined in 1982 by the Olfactory Research Fund, now known as the Sense of Smell Institute, a division of the Fragrance Foundation, which has funded numerous medical, university and individual studies on the effects of scents on sleep and performance. Aromachology differs from aromatherapy.
An aromachologist is a formulator who works with essential oils for their aromatic and physical effects and is an expert in the way essential oils can be blended and articulated together to create “behavioral fragrances” to establish the positive effects of aromas on human behavior including feelings and emotions.
The aims of aromachology are to “study the interrelationship of psychology and the latest in fragrance technology and to transmit through odor a variety of specific feelings (such as relaxation, exhilaration, sensuality, happiness and achievement) directly to the brain.
When odors activate the olfactory pathways that lead to the limbic portion of the brain they trigger the release of neurotransmitters that affect the brain and mental state of the individual in a variety of ways. Further, stimuli transmitted to the limbic system cannot be consciously blocked and all olfactory stimuli therefore influence our emotions.
Smell as a sense is the last frontier of neuroscience and has not been studied in as much depth as vision and hearing. The brain is able to process small differences in smell and the sense of smell may last longer in the aging process than sight and hearing. The olfactory bulb is that portion of the brain which processes smells information and its oscillations alter dynamically according to the tasks involved.
