The Art of Using Essential Oils

Have you ever had the experience of smelling something that causes you to relive an old experience? You actually feel the old feeling as if you were living it again — not just a memory. Maybe your heart races, or you feel hot all over.
When I was in college, I took a date to a Chinese restaurant. I ordered my favorite Chinese chicken salad, and subsequently spent most of the night kneeling in front of the toilet. For years, every time I smelled sesame oil my stomach would turn and I couldn’t eat. Interestingly, I could tolerate all the other ingredients: chicken, lettuce, green onions, and so forth. It was just the distinctive smell of sesame oil that caused nausea.
Our sense of smell can have powerful effects on the body through our feelings and memory. The link occurs because you process smell in the hippocampus and amygdala, parts of the limbic system, or the “emotional brain” — the same area where memories are processed. This is the same part of the autonomic nervous system that controls blood pressure, heart, hormones, breathing, stomach, organs and so forth. Because of this, essential oils have the potential to have far-reaching effects on the body.
Essential Oil Basics
Essential oils have been called “the life blood of a plant.” Oils are called “essential oils” when they are pure extracts of the plant. They are named “essential” because they bear the very essence of the flower, petals, peels, berries, leaves, bark, wood or roots from which they are derived. All substances can be broken down into an array of molecules and atoms, and essential oils are no different. Each essential oil can be broken down into a collection of different natural chemical constituents. These oils consist of a multitude of different substances:
- Aldehydes
- Fats (lipids)
- Terpenes
- Ketones
- Alcohols
- Phenols
- Esters
Essential oils are used by plants in somewhat the same way they are by humans. Essential oils:
- Fight infection
- Contain hormone-like compounds
- Initiate cellular regeneration
- Work as chemical defense against fungal, viral, and animal foes
Each plant’s oils have a unique makeup as a result of the plant’s own physiology, natural environment, and its potential microbial invaders. Despite their plant origins, essential oils have a similar structure to some compounds found in blood and tissues. This allows them to be compatible with our own physiology and easily absorbed into the human body. Essential oils pass through cell membranes, then further on into the bloodstream due to their “lipophilic” nature (a structure in alignment with the lipid components of our cell walls).
When using essential oils to treat illness, it’s important to take the individual person into account. One may negatively respond to an oil that will help another. Thus, there is an art to their use. The way we heal from illness is correlated to our internal function, much more than to the chemistry.
For example, of a hundred people exposed to the flu virus, only about 30% actually get an illness. If your balanced immune system is functioning, you may not get sick in the first place. If you do, you will be able to overcome and fight the infection. Antibiotics are really for people with a suppressed or non-functional immune system. Essential oils can be an adjunct to helping your body function properly to prevent and treat illness.
Essential oils can protect us from microbes in many different ways. From keeping the space around us naturally microbe-free, to readying our immune system for defense, to actually destroying the microbes once they’ve entered our bodies.
The two primary effects happen through olfactory reactions, or sense of smell, and the chemical reactions from applying oils to the skin.
Besides the effects caused from the odor, as the oils are absorbed, each substance further affects the body through action on hormones, receptors, the immune system, and energy production. These are generally absorbed readily through the skin, but some are volatile, meaning they evaporate, so they are taken orally.
This also allows more regional application since the lymph system is more local. This is why topical essential oil application is done for more localized effects.
When oils are ingested through the intestines they go straight to the liver, which can affect detoxification mechanisms as well as energy production. From there, they have access to cells and blood, and then to the rest of the body.
Safety of Essential Oils
While quality oils are non-toxic and safe, they are highly concentrated. Because they can have powerful effects on the body, you only need very small amounts. This is not one of those, “If some is good, then more is better,” treatments. When ingesting them internally it is often better to put them into capsules.
Someone told a friend of ours to use a couple of drops of pure oil of oregano for her 4-year-old son’s sore throat. He had been in bed for 2 days and was quite ill. She didn’t know how to administer pure oil of oregano. So she told her son to open his mouth and she shook a few drops of pure oil out of the bottle onto his tongue. The child immediately turned red and went screaming down the hall, running around the house throwing up, gagging and crying.
The mom didn’t understand what all of the fuss was about. After all, it was just an oil from a spice she used frequently in her cooking, so she put a drop or two on her own tongue. She said her tongue instantly felt like it was on fire. She turned red, her eyes watered up and ran through the house screaming and gagging, and finally to the kitchen for a glass of water! She apologized to her son profusely! However, 15 minutes later her son was well, laughing and playing. He was fully and permanently recovered from his illness!
How Essential Oils are Used
Using essential oils is an art that takes some time to master. Oils are not like drugs, which primarily enhance or retard the body’s natural functions. Where there is dysfunction and the body is not able to compensate, the oils will not change it.
For example, a person with diabetes may be told that lavender and cinnamon oils help to regulate sugar. But if there is no change in diet and exercise oils will make little difference. Oils are best used as part of a program, especially in the case of chronic illness.
That said, it is important to understand how our medical system uses drugs:
- To block or stimulate receptors in the body
- To kill bacteria or viruses
- To effect chemical reactions
Let’s look at some common ailments, and some simple regimens that can be useful for specific problems. These examples will provide some of the spectrum of the uses of essential oils.
