Blood Brain Barrier & Essential Oils
More than 100 years ago it was discovered that if blue dye was injected into the bloodstream of an animal, that tissues of the whole body EXCEPT the brain and spinal cord would turn blue. To explain this, scientists thought that a “Blood-Brain-Barrier” (BBB) which prevents materials from the blood from entering the brain existed.
Because the blood–brain barrier prevents entry into the brain of most drugs from the blood it makes it very difficult to develop new treatments for brain diseases, or new radiopharmaceuticals for neuroimaging of brain. All of the products of biotechnology are large molecule drugs that do not cross the blood brain barrier. Currently, less than five per cent of drugs (made up of very small molecules) are able to cross the barrier.
I found one of the interesting facts about getting through the blood brain barrier with medication. It seems that essential oils can cross easily. It is because of their volatile nature (rapid evaporation) that many oils are able to help in deep healing of the cells and that some oils appear to cross the blood-brain barrier and affect the emotions and the brain. Although most of the components of an essential oil have the power to heal, it is often the lightest chemicals that are able to penetrate first to the cells. Some, like the monoterpenes, carry oxygen, while others such as phenols help improve the functioning of the cells by removing wastes. One of the most important implications of the light, volatile molecules in an essential oil is how it impacts the health of the brain. Most medications are unable to directly affect the brain: the blood-brain barrier filters almost all chemicals in the blood, blocking them from entering the brain. The light, small molecules in an essential oil are different. They are able to cross over the blood-brain barrier and are used therapeutically to help those with memory loss or other brain disorders, Alzheimer’s, depression, ADD/ADHD, heavy metal toxicity, and more.
For years I confused Essential Oils with Aroma Therapy but they are quite different. Aroma therapy are oils are inhaled into the lungs and offer both psychological and physical benefits, they can stimulate the brain and trigger reactions with naturally occurring chemicals. A common one most people use is eucalyptus for congestion.
Essential Oils that are intended to be applied to the skin and can be absorbed into the blood stream. These oils are powerful and concentrated so they are diluted with “carriers” like cold press oils, sweet almond and apricot kernel oil. For those looking for a safe and effective remedy they are worth looking into.

I’m a huge fan of essential oils. It’s too bad essential oils and any other type of non-pharmaceutical treatment is considered woo woo nonsense and is debased in the mainstream. So many people could benefit from the help of something that actually provides relief.

Thanks I agree completely , so many good remedies are available in natural form but it’s always about the money . Thank you for your comment !
