of the brain that regulates our sense of smell . The olfactory system is connected to the limbic system where emotions and memories are stored .
When using essential oils aromatically , the scent travels through the nose to the olfactory system where it is processed , and then travels through the olfactory nerve to the limbic system . In the limbic system , the scent triggers responses in the brain based on memories and experiences . Because of these reactions in the brain , essential oils have a particularly powerful effect when applied aromatically . Due to the volatility of essential oils , aromatic use of essential oils is the most effective application method — the oil user can experience the benefits of a scent quickly and conveniently . When using essential oils aromatically , they are easily inhaled and absorbed through the respiratory tract and lungs , and then circulated through the blood stream .
As we breathe in the scent of an essential oil , it triggers specific reactions based on our own individual emotions , behaviors , memories , and experiences . This is why aromatic use is such a big part of mood management — reactions in the brain cause physiological reactions that can alter and improve mood .
