Short Answer? Yes.

Long Answer? Absolutely yes.

Okay but seriously? The reason why essential oils work are due to 2 main reasons.

  1. Essential Oils are teeny tiny.
  2. Essential Oils possess medicinal elements that effect us in serious ways
  1. Essential Oils are teeny tiny

Did you know that the average human body has on average about 37.2 trillion cells in it (source!)? That’s a lot! If I write it out long hand it looks even more amazing. Here it is. 37,200,000,000,000. Those cells make up everything. White, red, brain, muscle, heart, organs, skin. Everything.

But did you know that in a single drop of essential oil, there are approximately 40 million trillion molecules? Lets compare that with the amount of cells in our body in long form!

Cells in human body: 37,200,000,000,000
Drop of Essential Oil: 40,000,000,000,000,000,000,000

In every drop of Essential oil there is more then 40,000 molecules for every cell in our body!

“In every drop of Essential oil there is more then 40,000 molecules for every cell in our body!”

It is this incredibly tiny size that lets the active ingredients in Essential oils affect our bodies with different properties. The molecules are small enough to pass through our blood brain barrier which is why essential oils can boost or dampen our mental energy or focus depending on what effect we’re going for. It passes through any membrane of our damaged cells, our organs, our entire bodies as our body needs.

It was thought for years that the interstitial tissues of the brain served as a barrier to keep damaging substances from reaching the neurons of the brain and the cerebrospinal fluid. Instead of a barrier, it would be more accurate to consider it as a sieve or filter through which only molecules of a certain size or smaller can pass.

Most of the molecules of the substances used in chemotherapy are too large to pass through the blood-brain filter, which is why doctors say that chemotherapy doesn’t work on brain cancer. Some of the smaller molecules get through, but not the whole suite of drugs intended.

Doctors don’t know for sure, but it seems that in order to cross the blood-brain barrier, only molecules less than 800-1000 atomic mass units (amu) in molecular weight can get through. Lipid solubility seems to be another factor which facilitates passing through the blood-brain barrier. Water soluble molecules don’t usually penetrate into brain tissue, even when very small. The molecules of essential oils are all not only small, but lipid soluble as well.

In fact, when it comes to essential oils, small molecules (less than 500 amu) are what they are made of. That is why they are aromatic. The only way for something to be aromatic is for the molecules to be so small that they readily leap into the air so they can enter our noses and be detected as odor and smell.

That is why oils for cooking or massage, such as corn, peanut, sesame seed, safflower, walnut, almond, canola, olive and other oils pressed from seeds are not aromatic. Sure, they have a smell, but you can’t smell them across the room in minutes as one can when you opens a bottle of peppermint, hyssop, or cinnamon oil. Essential oils of every species cross the blood-brain barrier.

This makes them uniquely able to address disease, not only from a physical level, but from a more basic and fundamental level-that of the emotions which are often the root cause of physical illness.
