Essential Oils: A Primer

Rose oil is one of the best for anti-aging

If you’re like me, you’ve been using essential oils for as long as you can remember without a clear understanding of how they work.  Over the years, I’ve read a little about them here and there and been inspired to try them for various issues.  The more I’ve used them and learned about them, the more I appreciate them.  Finally, I’ve taken the time to get a better understanding of the how and the why.

I find their history fascinating.  This write-up from The Essential Oils Academy shares from the beginning of recorded history, the plant kingdom has provided powerful extracts and essences that have been prized for their beauty-enhancing, medicinal, spiritual, aromatic, and therapeutic values.  There is evidence of plant elixir use in Egypt, Ancient Greece, and past- & present-day India, where they are a remedial element of Ayurveda. You will find mention of them in the Bible. They have even been utilized by physicians through the ages to treat soldiers during wartime.  And now in Europe and North America, their use is widespread.

Oregano oil is a powerful household cleaner & immune booster

If you’ll remember, in my post For the Love of Trees, I shared that plants emit an abundance of chemicals that benefit themselves as well as animals, including us.  Essential oils are a condensation of these phytochemicals as a result of distillation.  Because so much plant material is required to make them, the oils are super-concentrated, strong medicine.  (And sometimes quite pricey.)  

Essential oils are used in all kinds of products, from cleaners to insect repellants, body lotions, and face creams.  But even when we don’t apply the oils directly, their aromas can have profound impacts.

Essential oils of lemon & lime heighten mood

Years ago, I remember walking into a casino in Las Vegas and realizing I was being drenched in aromatherapy.  I read up on it, and learned that casinos began using these scents to increase profits in 1991.  Presently, every spot on the Las Vegas Strip has a proprietary scent that is constantly emitted from their ventilation system.  Scent marketing is now a multi-million dollar industry, also used in medical offices, retail stores, and sports stadiums to help us remember our visits as pleasant ones, encouraging our return.

How can the scent of these plant oils have such strong effects?  I was curious, too.  In The Ultimate Guide to Aromatherapy, Jade Shutes and Amy Galper elucidate: the olfactory tract sends nerve impulses to the limbic system, including the heavily-innervated amygdala.  The role of the amygdala in emotion, memory, and autonomic control directly ties olfaction to these primordial functions and adds complexity to the odor perceptual experience, they writeThat explains why scents from the past can take us back.  (For more on the power of smell, check out my post Smellscapes.)  

There are a number of essential oils made from conifer trees, and many have analgesic effects

The book is filled with information on specific oils and their benefits.  Many are anti-bacterial, anti-viral, anti-inflammatory, and anti-aging.  In my experience, a whiff of lavender oil can help with sleep.  A couple drops of peppermint oil on the hairline gets rid of headaches, and rubbed onto muscles, it eliminates or reduces pain.  I’ve also found diffusing eucalyptus while showering helps with a stuffy nose.  But that’s just scratching the surface.  There are oils used for healing wounds & various skin afflictions, reducing anxiety, increasing alertness, and helping with nausea.  (I would suggest adding the oils to an unscented lotion or carrier oil for application, doing a test patch before applying liberally, and reading up on possible effects on children and pets prior to using.  Also, make sure you’re purchasing oils that are organic if possible & sustainably-sourced.)

The little bit of digging I’ve done on essential oils has helped me to understand just how they have helped me through the years. I hope the information I’ve shared encourages you to try these phytochemical powerhouses, yet another of Nature’s gifts to us, in a variety of ways.

  1. A great post, Lisa, I might just check out that book! It’s strange that your picture of lemons and limes has my teeth on edge 😉 and so pictures, like scents, can evoke many reactions. 😊 Have a wonderful weekend 🌹🙋‍♂️

  2. I’ve used oils for years for different reasons but never knew they were in the air system of businesses to help control our thinking and buying. My first encounter years ago was when someone told me to rub peppermint oil on my temples and wrists for a severe headache. It worked!

  3. Unfortunately, Linda is prone to migraines, but she has been doing a good job of keeping it under control with diet and identifying the root cause when one occurs – one of the main triggers she was told about by her specialist..and confirmed by her own experiences are smells. Perfumes, new materials and oils. Glad to hear others are able to find benefit in those products.

  4. I don’t know much about essential oils, but I remember how my grandma always had peppermint oil next to her bed which she used for headaches … and that’s something I still use today (thanks Granny). And thanks Lisa for educating me more on the use of essential oils 🌸.
