In case you didn't know this -
That beautiful sense of smell, the gateway to your olfactory system, is one of the most quick and powerful channels into the body.
When a drug like co***ne for instance is inhaled, it goes straight into the bloodstream via blood vessels in the nasal cavity. Once entered into the bloodstream, the chemical compounds travel quickly to the brain, for an intense reaction shortly after inhalation.
🍃 Similarly, when essential oils are inhaled, they efficiently pass through the blood brain barrier in the area surrounding the olfactory nerve.
🍃 Research demonstrates that inhalation can be the most direct method of getting essential oils into the body. From the inhalation of an essential oil to a response in the body, we're talking seconds compared to 10 minutes or more
when swallowing a capsule or pill.
🍃 The blood/brain barrier in the brain is approximately 8 cells in thickness. The number of cells that make up the layer surrounding the olfactory nerve is 4 to 5 cells thick. It is almost effortless for essential oils to pass straight through to the brain when breathed in through the nose.
