The Blood Brain Barrier (BBB) is a filtering mechanism or system of the capillaries which carries blood to the brain and spinal cord tissue. It protects the brain from foreign substances in the blood that may injure the brain. It also protects the brain from hormones and neurotransmitters in the rest of the body. It is a built-in constant and protective environment for the brain.
Large molecules don't pass through the BBB.
Low lipid (fat) soluble molecules do not penetrate into the brain.
However, lipid-soluble molecules, rapidly cross through into the brain.
The molecules of essential oils are all not only small, but lipid soluble. All Essential oils cross the blood-brain barrier, reaching the brain.
Aromatic, essential oils circulate in the air, enter our noses, and detected as a smell.
Whether it is by diffusing it into the air, or penetration by rubbing it on the skin, or internally, using Therapeutic methods, Essential oils affect the brain by entering the blood.
The blood-brain barrier is like a locked facility and lets only the most selected into these delicate tissues of our central nervous system. This gate only allows passage of specific compounds crucial to the brains function, such as some amino acids, glucose, and particular Sesquiterpene.
Essential oils contain Sesquiterpenes, and can directly cross the BBB because of their molecular size. They also carry Monoterpenes, which are even smaller than sesquiterpenes.
These unique organic properties give essential oils a powerful biological impact throughout the body, healing as it goes.
Essential oils penetrate not only the BBB, but they can also penetrate into the skin, following the nerve pathways, They provide healing, and can balance us at a cellular DNA level, again supporting brain health.
It all comes back to optimal brain health, which produces optimal body tissue health. The circle of life can improve with Essential oils.
