How Essential Oils Can Heal Brain Injuries

Our sense of smell is the only sense that is directly tied to the limbic area of the brain, which is considered the emotional control center. And when we inhale essential oils they go directly to the brain. The other four senses — taste, sight, touch and hearing — are first routed through the thalamus before reaching designated areas of the brain.

Therapeutic-grade essential oils can have amazing psychological and physiological effects since the limbic system is directly connected to parts of the brain that control blood pressure, heart rate, breathing, stress levels, memory, and hormone balance. Every essential oil has therapeutic calming, sedative, stimulating, and balancing properties. The inhaled molecule of the essential oil travels through the nasal passage to a receptor neuron that transports it up to the limbic brain, particularly the hypothalamus. The limbic center in the brain controls all the physical, psychological, and emotional responses that the body performs based on stimuli that come from the outside. Therefore, the capacity of essential oils to target the limbic center makes them a powerful tool in the treatment of many health diseases. 

When you inhale essential oils, the tiny nerves immediately send a signal to the brain and go straight to work on the systems that moderate your mind and body. The chemical messengers in the nasal cavity have direct access to the brain, which makes inhalation the most direct delivery method of these amazingly nurturing components in essential oils.

Universities from Vienna and Berlin have performed studies where they discovered that sesquiterpenes, natural compounds found in essential oils of Patchouli, Vetiver, Sandalwood, Melissa, Myrrh, Cedarwood, Clove, Cedarwood and Frankincense, had the ability to increase the levels of oxygen in the brain by up to 28% (Nasel, 1992). This increase in brain oxygen can lead to a heightened level of activity in the hypothalamus and limbic systems of the brain, which could have dramatic effects on emotions, learning, attitude, and other physical processes of the body such as: hormone balance, immune function, and energy levels.

In 1989, Dr. Joseph Ledoux, at New York Medical University, discovered that the amygdala has a major role in releasing and storing emotional trauma. This leads to the conclusion that aromas may exert a significant effect in triggering a response.

Whether they are diffused or directly inhaled from the bottle, essential oils can provide many benefits to the human body without any side effects. When the olfactory nerves are properly stimulated they can offer a powerful and entirely new form of therapy that could be used as an adjunct against many forms of illness. Although the therapeutic effects of essential oils, through inhalation, are relatively unexplored, it seems that they may occupy an important position in this frontier in medicine.

Essential oils are currently being evaluated for brain injury treatments due to the ability of their molecules to affect both physical and psychological functions in the body.

The human brain is the most complex organ in the body. Brain injuries range from mild concussions to more serious head trauma. Various brain injuries usually heal slowly, and frankincense oil was found to significantly aid in this process. Frankincense aids oxygenation of blood going to the brain, which aids in oxygen absorption. When oxygen is effectively absorbed, it allows the brain to process and retain information, heal, and function properly.

Frankincense is the essential oil of choice for any kind of brain disorder. Its molecular makeup includes sesquiterpenes, which are able to cross the blood/brain barrier. Sesquiterpenes stimulate the limbic system of the brain and other glands within the brain, and promotes memory and releases emotions. Frankincense also slows down and deepens the breath. Its therapeutic properties are antiseptic, carminative, astringent, cicatrisant, diuretic, cytophylactic, digestive, emmenagogue, expectorant, sedative, uterine, tonic, vulnerary and expectorant.

The research conducted in the universities from Berlin and Vienna found sesquiterpenes to increase oxygenation around the pituitary and pineal glands. This contributes to an ideal balance of memory-stimulating and emotion-regulating hormones.

Essential oils can not only penetrate the blood-brain barrier, but they also penetrate the skin, follow nerve pathways, follow the meridians, and provide balance and healing even at the cellular level such as cellular memory and DNA.

Diffusing and Inhaling
According to research, diffusing certain oils using a cold air diffuser may have these benefits:
– Relaxing the body, clearing the mind, and relieving tension.

– Help with weight management.

– Reduced bacteria, fungus, mold, and odors.

– Improved hormonal balance.

– Improved secretion of the antibodies that fight candida.

 Relieved headache.

– Stimulation of neurotransmitters.

– Improved concentration, mental clarity and alertness.

– Stimulate secretion of endorphins.

– Improved digestive functions.

– Stimulate the production and receptivity of the growth hormone.


The level of purity and therapeutic value of an oil depend on its chemical constituents. This can be affected by things like the soil from which the plant was grown, the condition of the soil, fertilizer (organic or chemical), climate, distillation process, etc.

In aromatherapy, the quality of the oils is very important if they are to have healing benefits. It is important to use undiluted therapeutic grade essential oils. Always check if the label says “100% therapeutic grade essential oil”. However, although some essential oils are labeled as l00% organic, this does not mean that they are pure.

The purity of therapeutic quality essential oils is laboratory tested and certified. A therapeutic-grade essential oil is complete in its chemical constituents, that give it a rich, deep aroma, and is kinetically alive and able to raise the frequency of the human body, restore balance and normal function to weak body systems. This is vital,because the fragrance, frequency and chemistry of the oil contribute to its unique therapeutic effects. And if any of these properties are compromised, due to poor production practices, the essential oil cannot be called therapeutic-grade.
