and to examine the relationship between feelings and emotions. Those who practice aromachology are aromachologists. Aromachologists analyze emotions such as relaxation, exhilaration, sensuality, happiness and well-being brought about by odors stimulating the olfactory pathways in the brain and, in particular, the limbic system.
[C. X. Wang, Sh. L. Chen, Aromachology and its Application in the Textile Field, http://www.fibtex.lodz.pl/54_14_41.pdf] Different wearers are thought to have unique physiological and psychological responses to scents, especially those not manufactured synthetically but based on real scents. The word "aromachology" is derived from "aroma" and "physio-psychology", the latter being the study of aroma. This term was coined in 1989 by what is now the
Sense of Smell Institute (SSI), a division of
The Fragrance Foundation.
[Maria Lis-Balchin, Aromatherapy Science: a Guide for Healthcare Professionals, p. 3, (2006), ] The SSI defines aromachology as "a concept based on systematic, scientific data collected under controlled conditions". The term is defined as the scientifically observable influence of smell on emotions and moods. Consumers use aromachology to alleviate time pressures, for relaxation or stimulation and as a component of other activities that generate a feeling of well-being.

Although certain plants are known through studies in aromatherapy to have
stimulating or relaxing effects, research on wider scopes of application for therapeutic purposes are still at an early stage. Aromachology devotees want to find out how psychological effects are transmitted from scent to the brain, as well as how positive behavioral effects can be induced by scent.
Maria Lis-Bachin, author of ''Aromatherapy Science: a Guide for Healthcare Professionals'', notes an overlap between the objectives of aromatherapy and those of aromachology.
However, despite this apparent overlapping, academic authors believe that they are distinct branches of research and application, with each having its own research methods and directions.
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.

A Journal of Society of Cosmetic Chemists of Japan in 1992

On the study, the effect of odor on cardiac response patterns was investigated on human subjects during a period of two-stimulus paradigm in a simple reaction time task.
During the experiment changes in the cardiac response pattern were obvious and heart rate deceleration reflecting the process of anticipation or attention.
Olfactory stimulation was provided to the subjects with different aromatic air samples with a 5-second rest period, followed by a 20-second olfactory stimulus period. It was concluded that the odor of lemon, traditionally thought to be stimulative, had the effect of activating anticipation or attention process. The effect of activating the anticipation or attention process was stronger when the odor intensity was more concentrated. On the other hand, the rose odor initially was thought to be sedative, had the effect of suppressing that process.

s. Smell 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.
Commercial application of aromachology
From the point of view of creating a scent for the body, a number of aromachology practitioners and small companies interested in aromachology are focused on creating bespoke perfumes for individuals who are less interested in purchasing the same fragrances that every other person is wearing and more inclined to wearing a perfume tailored precisely to their own preferences, memories and scent matches. Some cosmetic brands such as

and Décléor are devoting substantial efforts to the task of finding out the beneficial properties of aromas on our sense of well-being and health. Shiseido currently has a skincare line called "The Skincare" that uses aromachology in their products.
Broader applications for aromachology are found in industries that introduce scent into products other than cosmetics or perfumes. Aromachology is considered to also encompass scents introduced to home fragrances, textiles, drawer liners and odor reducers for the home environment.
Aromachologists
Aromachologists work with essential oils for their aromatic and physical effects and are experts in the way essential oils can be blended to create "behavioral fragrances" to establish the positive effects of aromas on human behavior including feelings and emotions.

reduce stress in humans as well as reducing stress-related high blood pressure. The Mind Lab, an independent consultancy in the UK, studies the odor of a building as part of research on the brain's responses to stimuli. Real estate brokers have been recommending to their clients to have smells of freshly baked cookies or the aroma of coffee in the house when it is being presented to potential buyers to create a sense of home. By bottling and releasing appropriate smells to evoke comfort, safety and joy, an owner may be able to accelerate the sale of a house.
Worker productivity can be enhanced by improving the quality of air in a building, not just by removing the negative pollutants, but also by introducing olfactory stimulation through ventilation or air conditioning systems in order to get a mix of ventilated air and odor.
It is necessary to ensure that the dosage is such that the odor is not excessive and should be kept just above the detection level. Also, these olfactory substances are very different from perfume and should instead replicate the smell of natural outdoor air.
