The Science Behind Emotional Oils

How does a whiff of pumpkin pie transport someone back to their grandmother’s Thanksgiving table? Or the smell of a fresh topsoil instantly bring back the heartache of a long-lost man’s-best-friend? There is actually a scientific reason why certain smells can trigger strong memories and emotions from the past to resurface in our minds.

How the Sense of Smell Works

The sense of smell is considered a chemical sense because it enables us to detect chemicals in our environment. With far more receptor sites for smell than any other sense, our sniffer is 10,000 times more sensitive than our other sensory organs, giving us the ability to differentiate among thousands – if not millions – of different odors. Here’s what happens in the process of smelling:

  1. Odor molecules in the air reach the nostrils and dissolve in the mucus on the roof of each nostril.
  2. Beneath this mucus layer, smells are transmitted to receptor cells that detect the odor.
  3. The olfactory receptor neurons transmit the information to the olfactory bulb located at the back of the nose.
  4. The olfactory bulb directly connects to the limbic portion of the brain where the odors are perceived. This highly-specialized portion of the brain is also home to the amygdala (responsible for our emotions and feelings) and the hippocampus (where our memories are stored.)
  5. These brain centers perceive odors and simultaneously access memories and their associated feelings and emotions to remind us about people, places, or events associated with specific smells.

Smell and Memory

The reason smell can trigger a memory or feeling so effectively is that other senses like touch and taste must travel through the body via neurons and the spinal cord before reaching the brain. So smell is the only sense with “direct access” to our brain. In addition, smell is the only sense that is perceived in the limbic portion of the brain, where memories and emotions are handled.

We Just Took Essential Oils to Another Whole Level

When I first learned about essential oils such as Forgiveness, Hope, Believe, and other “feelings” oils, I did not put much faith in their ability to work as their names claim. For example, the Young Living website describes Hope essential oil this way:

Hope essential oil is a unique blend that helps you reconnect with optimistic feelings of strength and grounding.

My initial thought was that I would rely on the Lord for my hope, thank you very much. While I still proclaim that my hope does indeed come from the Lord, I have come to learn that this oil has been formulated using chemical constituents that are known to react with specific molecules in the limbic portion of the brain that actually trigger emotions of optimism and strength. With a background in biology and chemistry, this gets my attention.

Most of you reading this are probably already using essential oils and loving the benefits of them. Hopefully you are even discovering that a single oil can have multiple advantages because of the amazing chemical complexity in each tiny drop. You have probably learned that essential oils can offer support to every single system in our bodies. So why do so many “oilers” dismiss the idea of how oils can benefit us emotionally? It is okay to use oils for common ailments, first aid, and even some more serious health concerns, but it is taboo to suggest that an oil can support our emotions and feelings?? I, too, once thought this way, until I studied the chemistry of how the oils work in our brains, and even more so when I tried some of them.

Let’s Get One Thing Straight

The feelings oils were never intended to replace a relationship with the Father. After all, essential oils have been ingeniously designed by the Father Himself to bring us closer Him. What is even more mind-blowing is how essential oils can actually assist us in releasing damaging negative emotions and accessing those feelings and emotions that help us connect with Him more deeply. So if using an oil can “activate” your physical brain to encourage a desired emotion, imagine how the power of your prayers can be magnified to activate your subconscious mind, where your beliefs are seated!

What Have You Got to Lose?

If this is a new idea to you, or if you are like I was – skeptical and doubtful about the emotional benefits of oils – I urge you: put aside your doubts, fears, and concerns. Prayerfully seek the Father and see what He has to say about using an oil that He created to support your emotions. Put on a dab of Believe and open your mind and heart to hear from the Lord. Then just let Him speak to you.
