No Sense is More Important than the Olfactory Sense!
I really want you to understand that a perfume is not only a smell, it is much more than that and everyone should really know this before learning to become an olfaction trainer, an aromatherapist or a perfumer.
When you smell a perfume:
-going through your brain, it creates memories and sensations.
-it has an action on your nervous system, regulating organs.
-it is also a gas and what we breathe has immediate access to our blood. While penetrating through the thin membranes of our lungs, fragrances and perfumes reach the bloodstream much more quickly than the absorption of matter by the digestive tracts.
-it influences your hormonal system
-it acts on your organs through your nervous system
-in the bloodstream, it participates to the irrigation of your organs
-it can also modify your DNA and your cell's organization
Digestion and the breaking down of solids, like medicinal pills, take much more time reaching the bloodstream, as the absorbed solids must be digested and pass through the thick intestinal wall.

These are the reasons making a perfume or blending essential oils has responsibilities. 
When you teach olfaction training, when you train yourselves, when you create natural perfumes or when you blend essential oils, always study the particularity of the oils. Do not use products without knowing their origins.
Olfaction can be dangerous. With essential oils, you can always find data and talk to the person in front of you.
With synthetic substances you have no historical data like we have for flowers and plants. Natural Perfumes are more expensive but it is worth to consider !

Perfume, by simple olfaction, sends messages to the nervous system, especially, to the area called "the big sympathetic" which plays a very important role in the maintenance of the health balance of humans.  
The nervous system is the supreme organizer of matter, where life emanates. Its actions spread to all the organs where it regulates the different functions to achieve this harmonious whole that is the human body.
Besides, it assures the defense of the organism in protecting the body from external attacks.
”The big sympathetic” is made of a double chain of joint ganglia, situated at each side of the backbone. From these ganglia emerge many nerve connections terminating at the vegetative life organs: liver, spleen, lungs, heart, blood vessels, etc.

In some regions of the body nerves also form real networks, and insure the communication of the big sympathetic with the central nervous system.  
The nervous system presides in exchanges, warns of failings, provides the various organ needs and rescues those that are threatened.   
It directs the natural defenders: the white blood cells or leukocytes, also called phagocytes.   
The stronger the microbial attack the stronger the defense.     
Different conditions, by their suddenness or duration, can cause an abrupt disruption in the balance of the nervous system and also on the entire organism.  A failing nervous system can occur in different ways: tiredness, insomnia, unaccustomed emotional stress, sudden weight loss, or an uncharacteristic tendency to exaggerate or discourage.  If, at this moment, a bacterial attack occurs, the nervous system would not have the necessary strength to fight it.

Within the nervous system is the autonomic nervous system, which then contains the sympathetic and parasympathetic nervous systems.
These two systems are involuntarily, meaning our body does not have control over what it is being performed.

The sympathetic nervous system is known as “fight-or-flight”, while parasympathetic is known as “rest and digest”.
Even though they are different, these systems still work hand in hand with one another to help control the way our body works.
Sympathetic is almost like an alarm clock, as it arouses the body and stimulates the nerves to start working. On the other hand, parasympathetic helps calm the body down, as it brings the body back to its normal state.
Natural essential oils can rebalance your nervous system, therefore it is important to learn aromatherapy and olfaction training before learning natural perfumery.
