Aromatherapy is the use of essential oils obtained from aromatic plants for physical and psychological health.

It is important for a better understanding of aromatherapy. Effects of odors on humans
The branch of science that studies it is called aromacology. The purpose of aromacology is the use of aromatic chemicals.
To determine whether inhalation affects mood, physiology, and behavior. Actually

The most emphasized phenomenon in aromacology is the mood, behavior and physiology of odors.
how and why it produces effects on various aspects. These effects of odors
There are two main mechanisms that explain it: the pharmacological hypothesis and the psychological hypothesis.
The pharmacological hypothesis is that the effects caused by odor are due to the nervous system or the endocrine system.
It says that it is caused by its interaction with (hormones). Pharmacological action of a volatile compound

The puzzling part of the pharmacological hypothesis is that they smell the same but are chemically different.
whether the molecules will produce the same effect. However, in some studies the same
The important thing is that many different variants of fragrances are used and produce similar results.
It shows that it is not the chemical structure of the molecule, but the psychological perception of the smell. Beyond
On the other hand, there is a molecular order that contradicts this situation: chirality! Chirality, mirror of a molecule

will affect the results. The olfactory receptors are particularly susceptible to interactions suitable for molecular shape.
Therefore, the chiral forms of odor molecules smell different from each other. for example
The (-) form of the kavron molecule smells like cumin, while the (+) form smells like mint.
The psychological hypothesis, on the other hand, does not contain such a contradiction. The effects of odors are emotional.
It says that it manifests itself through learning, conscious perception, and belief or expectation. basically
associates responses to odors with emotional experiences. Much support for this hypothesis
There are many scientific studies available. Studies show that pleasant and unpleasant odors
Emotions have also been shown to influence the physiological relationships of emotion, as expected.
