Study Explains What Happens To The Brain When You Diffuse Essential Oils

By Jennifer Giustra-Kozek, LPC, NBCC

• The Facts: Multiple studies have outlined the potential benefits one can receive through the use of essential oils. The study presented in this paper shows it can have positive effects on the human brain.
• Reflect On: If we want to assist ourselves with regards to feeling better, or to help with certain disorders, it’s important to know that there are many, non harmful options to try before using pharmaceutical medications.

Many are diagnosed with ADHD, depression, anxiety and sleep disorders. In 2013, a medical expenditure survey determined that 1 in 6 Americans take  psychiatric medication on a daily basis. Consequently, 90,000 adults and countless children visit the emergency room yearly for side-effects of these medications including, increased depressive or anxious symptoms, brain fog, confusion, heart palpitations, dizziness, muscle spasms, seizures, tics, and psychosis.

Despite these side-effects and the many black box warnings including death by suicide, many continue using them. It is about time we start addressing root causes of these emotional issues such as poor diet, trauma, leaky gut syndrome, toxicity, and nutritional deficiencies. It is also important that everyone recognize the power of plant medicine. Here we take a look at the healing benefits of essential oils.

“Nature itself is the Best Physician.” – Hippocrates

It’s Not Pseudoscience

Essential oils stimulate the limbic system – the part of the brain involved in memory, mood, motivation, and behavior. And, scientific studies demonstrate that the purest essential oils are powerful plant medicines that have a wide range of emotional wellness applications, including depression.

In inhalation aromatherapy, the inhaled air containing essential oils can not only reach the circulation system via the blood capillary network in the nose and the bronchi in the lungs but also stimulate brain areas directly via the olfactory epithelium. Essential oils trigger mechanisms in the brain via the olfactory system. The mechanism of action of essential oils administered by inhalation involves stimulation of the olfactory receptors cells in the nasal epithelium, about 25 million cells, connected to the olfactory bulb. After stimulation, the signal is transmitted to the limbic system and hypothalamus in the brain through the olfactory bulb and olfactory tract. Once the signals reach the olfactory cortex, release of neurotransmitters, for example, serotonin, takes place which results in the expected effect on emotions related to essential oil use

According to the National Association of Holistic Aromatherapy, essential oil is the oil extracted from a plant through careful steam distillation, resin tapping, and cold pressing.  Essential oils get extracted from many parts of the plants including flowers, barks, stems, leaves, roots, and fruits.

Using Oils Safely

Quality matters: Organic oils from reputable companies or homegrown is the best. You want pure, organic and authentic oils to decrease the likelihood of adverse reactions.

Dilute certain oils: Those rich in aldehydes (e.g., citronellal, citral) and phenols (e.g., cinnamic aldehyde, eugenol) should always be applied with a carrier oil like almond, coconut or avocado. Mixing irritant oils with others to create a blend can also reduce an adverse reaction.

Application: Oil may be applied to the skin or diffused with relatively no risk. Some essential oils are ingestible. However, ingesting oils is not recommended unless under the advisement of a qualified herbalist or alike.  Anecdote: It is never one size fits all. Most aromatherapy oil-based blends will be between 1 and 5 percent dilutions, which typically does not represent a safety concern. As one increases dilution, potential dermal (skin) reactions may take place depending on the individual essential oil; and the area in which the oil is applied.  One may be sensitive to a particular essential oil, just as they may be sensitive to a specific food. So, make sure to take precautions is always recommended.

Not one size fits all: A particular oil may invite relaxation for one, and may create the opposite reaction for another. We need to remember that we are all bio individual. People with specific allergies to ragweed and other plants need to be more careful about having a similar reaction to oils.

Age matters: Babies and young children may be more sensitive to the potency of essential oils. Certain oils should be avoided, used highly diluted or under the guidance of a knowledgeable professional. To prevent reactions, applying diluted oils to the soles of the feet are often recommended in younger children.

Particular caution should be exercised with potentially toxic essential oils such as Birch and Wintergreen which are both high in methyl salicylate, Eucalyptus which is high in 1,8 cineole and Peppermint which is high in menthol. Elderly clients may have more skin sensitivities so a reduced concentration/dilution may be indicated.

The Takeaway

Other methods and interventions exist that can help treat ailments where doctors only seem to prescribe drugs. Essential oils are one example out of many, and a good example of how we all really need to look into things for ourselves instead of relying on so-called “experts.”

(WARNING: Please be careful about diffusing essential oils around pets. Research them first. Many are too powerful for animals and can cause toxicity and even death.)
