In 1991  olfactory receptors were linked to a very special protein, which made us understand that the molecules we breathe are perceived as a part of one of a largest groups of signaling mechanisms functioning in our body.
This mechanism allows the information contained in the smell of an essential oil to go beyond being just a chemical, like molecules flying in the air, towards signals that affect the cells directly, causing a reaction in them.
A large number of important physiological processes are involved in this stimulation process, which are associated with how the information detected inside the brain is processed and we know for now is that its own and independent patterns are created, which have nothing to do with our expectation about what we think we smell, because it awakens and activates unexpected areas every time.
This independence ensures that the information you can get from sniffing is simply a sure way to go beyond what you expect to find, your learned expectations.
The molecule’s (physical, real and three-dimensional) transformation into information that the brain and its cells can recognize, occurs due to our genetic information: we are encoded for it. Staying calm and relaxing can help in the process, which we will see in the next two articles:
- Black pepper, rosemary and Slique infusion as nootropics (to be published on April, 8)
- Chamomile, Lavender and Geranium: beyond normality (to be published on April, 14)
