Q&A With doTERRA's Dr. David Hill

Essential oils became much less confusing and more useable as soon as I learned more about their chemistry. I really enjoyed reading this article because, in my own experience, I knew the essential oils were working for me, but I wasn’t sure why or how. I am the sort of person that needs to know the ‘why’. Learning more about the chemistry can seem daunting which is why I love how Dr. Hill breaks it down for us. He gives an easy to understand explanation of the science behind how and why these drops can do so much for our wellness.  What other resources have you found that help you understand the ‘why’ behind your favorite oils?

If someone is allergic to a certain plant, can they still use the essential oils that come from those plants?
An allergy is the result of the immune system mistaking a substance as harmful and producing antibodies to fight it, resulting in various adverse side effects. An allergic reaction to a plant is caused by a plant’s protein-containing materials (i.e. the actual seed, leaf, or fruit). Pure essential oils do not contain these complex molecules, which are the primary cause of allergies. While an allergic response is unlikely, this does not mean one can use essential oils irresponsibly without risk. Understanding the proper use of an essential oil is always recommended, regardless of the circumstances. If you have concerns about sensitivities or interactions with other treatment plans, please consult your physician or health-care professional for additional guidance.

How do chemical constituents in essential oils affect us?
The chemical constituents of an essential oil are analogous to the macronutrients in food. Just as the fructose (sugar) composition of a banana provides instant energy and has specific metabolic effects, essential oils rich in Limonene can provide a powerful boost to your immune system. The chemical constituents in an oil determine its potential benefits, what metabolites it will produce, and best practices for application. Chemists have to date identified over 3,000 different molecules present in essential oils. Each of these amalgamations of carbon, hydrogen, and oxygen atoms have their own unique properties. These compounds are categorized based on their chemical makeup, which hints at their function and physiological activity. Oils high in terpene compounds (ending in "-ene") have different properties than those high in hydroxyl alcohols (ending in "-ol") or phenols or esters, and are therefore suitable for different purposes. Familiarity with the chemical building blocks of essential oils enables any user to practice aromatherapy more safely and effectively.

What’s the difference between Cinnamon Bark and Cassia essential oils? Is one better than the other?
While often thought to be the same, Cinnamon Bark and Cassia essential oils have distinct differences along with some similarities. Although extracted from different species (Cinnamon Bark from Cinnamomum zeylanicum, and Cassia from Cinnamomum cassia) they are both widely referred to as cinnamon and often used for similar purposes. Cinnamon is distilled from the bark of the cinnamon tree while Cassia is distilled from the stems and bark of the cassia shrub. Trans-cinnamaldehyde is the primary constituent in both, though the concentration is the primary chemical difference. Neither oil is better; however, the variance in aldehyde composition results in different ranges of benefits. I recommend Cinnamon Bark to support oral health and to purify the air, while Cassia elevates mood and promotes healthy digestive function.*
