10 Essential Oils for Brain Injuries That Doctors Don’t Want You To Know

Have you ever smelled something and it brought you back to a moment or memory in time? This is because our brains are highly interconnected with different aromas and smells. In fact, our sense of smell is the only sense directly related to the limbic area of ​​our brain. Not surprisingly, the limbic system deals with emotions and memory (1).

As I’ll discuss soon, the mechanism by which odor affects our brains can also be applied to brain injuries. In fact, there are over 10 brain injury essential oils that can be used for this purpose. But first, we need to take a look at what actually happens when we inhale the aroma molecules of an essential oil.

Aromatherapy and the brain

Aromatherapy, or essential oil therapy, is a type of alternative medicine practice that uses aromatic essential oils derived from many different healing plants. While aromatherapy applies to both inhalation and topical applications, for the purposes of this article, we will limit ourselves to inhalation.

When you inhale the aroma molecules of an essential oil (either directly from the bottle, diffused into the air, or inhaled through a steam bath), the olfactory system is stimulated. The olfactory system is the part of the brain connected to smell (including the nose and the brain).

Molecules that enter through the nose or mouth pass to the lungs, where they exchange immediately with the blood and reach other parts of the body. As these tiny molecules reach the brain, they affect our limbic system (as described above), which is related to our emotions, heart rate, blood pressure, breathing, memory, stress, and hormonal balance (2).

Essential oil molecules can also reach the brain through an alternate route that does not involve the lungs. This allows certain molecules that cannot cross the blood-brain barrier (BBB) ​​to gain direct access to the central nervous system (CNS) in a matter of minutes. The molecules reach the central nervous system via the olfactory and trigeminal neural pathways, two pathways that innervate the nasal cavity, providing a direct connection to the CNS (3).

For this very reason, essential oils are excellent candidates as natural healers for brain injuries and much more. But what components of essential oils help heal the brain? It all comes down to little molecules called sesquiterpenes.

Terpenes and the blood-brain barrier

The blood-brain barrier acts as a sieve or filter through which only molecules of a certain size or smaller can pass.

When it comes to brain injuries and brain tumors, most doctors resort to invasive procedures (which, under certain circumstances, are necessary). However, invasive procedures to the brain is it so risky, and if there were other ways to reach the brain holistically, which one would someone choose? The risky route or the not-so-risky route?

Let’s take chemotherapy as an example: most of the substances and molecules used in chemotherapy are too large to pass through the blood-brain filter. That’s why doctors say chemotherapy doesn’t work on brain cancer.

According to doctors, only molecules with a molecular weight less than 800-1000 atomic mass units (amu) can pass through the BBB. These molecules must also be lipid soluble (meaning water soluble molecules usually can’t get through). However, essential oils meet molecular weight requirements (less than 500 amu) and are also lipid soluble (4).

Essential oils are mixtures of hundreds of constituents, all of which are made up of a class of organic compounds made up of “isoprene units.” One unit of isoprene has a molecular weight of only 68 amu (very small). Molecules that are made up of isoprene units are classified as “terpenes,” the compounds that make all essential oils unique and different.

There are three terpenes found in essential oils:
– Phenylpropanoids (also called hemiterpenes) – formed by an isoprene unit (molecular weight 68 amu)
– Monoterpenes – composed of two isoprene units (molecular weight 136 amu)
– Sesquiterpenes – composed of three isoprene units (molecular weight 204 amu)

These three terpenes have the ability to pass the BBB, but it is the sesquiterpenes that contain the oxygenating molecules of the brain. As described by Dr. David Stewart (5):

“Sesquiterpene molecules deliver oxygen molecules to cells, just like hemoglobin does in the blood. Sesquiterpenes can also erase or deprogram misspelled codes in DNA. Sesquiterpenes are thought to be especially effective in fighting cancer because the fundamental problem with a cancer cell is that it contains wrong information, and sesquiterpenes can erase that distorted information. At the same time, the oxygen carried by the sesquiterpene molecules creates an environment in which cancer cells cannot reproduce. Thus, sesquiterpenes deal cancer cells a double whammy: one that disables their coded misbehavior and a second that halts their growth…

The American Medical Association (AMA) has said that if they could find an agent that crosses the blood-brain barrier, they could find cures for ailments such as Lou Gehrig’s disease, multiple sclerosis, Alzheimer’s disease, and Parkinson’s disease. Such agents already exist and have been available since Biblical times. The agents, of course, are essential oils, particularly those that contain the sesquiterpene molecules that oxygenate the brain.”

Studies conducted at the universities of Vienna and Berlin found that sesquiterpenes found in essential oils of vetiver, patchouli, cedarwood, sandalwood, and frankincense may increase oxygen levels in the brain by up to 28 percent (6).

10 essential oils for brain injuries

When it comes to curing brain injuries and tumors, we must choose essential oils that contain a high percentage of sesquiterpenes to maximize oxygenation of the brain. Every injury in the body requires oxygen to promote healing. And when it comes to cancer, cells prefer oxygen-starved environments to thrive and grow. With more oxygen, the cancer has a hard time staying alive.

The following essential oils are not only high in sesquiterpenes, which increase oxygenation to the brain, but also contain other chemicals that can nourish and help repair damaged brain tissue.

Sesquiterpenes are found in the following oils (7, 8):
Cedar wood (98%)
vetiver (97%)
Sandalwood (90%)
Patchouli (71%)
Myrrh (62%)
Ginger (59%)
ylang ylang (55%)
helichrysum (40%)
Melissa (40%)
Incense (8%)

It is the sesquiterpenes in these oils that are particularly effective in remediating hard-to-heal brain injuries.

How to use essential oils for brain injuries

There are many different ways to use essential oils for brain injuries. One of the easiest ways is to simply inhale the oil itself. You can do this by opening the essential oil bottle and then holding it just below your nose so that you can inhale the scent molecules.

Another way to use essential oils for brain injuries is to spread them in the air in your home. You can achieve this by invest in a diffuser and following the instructions on the machine to see how much essential oil you can use. I usually put 10 drops in my diffuser and run it for an hour.

Lastly, you can make a steam bath by pouring hot water into a large pot and putting 5 to 10 drops of essential oil. Next, place your head under a towel and over the pot, and inhale deeply so the oils are inhaled.

Always buy your essential oils from a good company. I always recommend the ones from Eden’s Garden or Mountain Rose Herbs.


Always remember that certain essential oils are toxic to cats and dogs. Never use the following essential oils around dogs or cats:
