I was in the beginning process of writing this blog post when a compelling article came across my Twitter feed on this very subject.
We all love essential oils, right? and use them in various ways every day. As essential oils have grown in popularity to the point where you can even purchase them in drugstores, the reports of adverse reactions have gone up in tandem. It is not that essential oils are inherently unsafe, but there are safety precautions for every essential oil and a potential risk for adverse reactions -- even from something as innocuous as Lavender.
There is a popular myth that if someone has a dermal reaction to an essential oil or blend that their body is just "detoxing" and that the reaction is the bodies way of saying that "you need this oil" or to continue using the oil or blend even if it is causing dermal irritation or sensitization. This information gets passed down a lot on websites, blogs, YouTube, and in essential oil related Facebook groups and it is categorical misinformation -- regardless of the purity of the oils that you are using. Purity does not equate to safety. Adverse reactions don't only happen when using cheap, adulterated oils, and this is an unfortunate fact. I am not intending to scare anyone, but you should be aware of essential oil safety before using oils yourself or making products or recommendations to family and friends.
If you have an adverse reaction to an oil - you may never be able to use that oil again for years or for the rest of your life. There are several factors that can lead to such reactions: incorrect dosing, frequency of use, longevity of use, type of application (especially "neat" undiluted applications), and your own personal bodily constituency. If you or someone you know has an adverse reaction, it is recommended to stop using the oil and seek medical attention. Not everyone will have skin reactions and most might be very minor.

My recommendation for burgeoning aromatherapists and essential oil distributors is to research and educate yourself on essential oils in general and their safety precautions -- and most importantly to do so through reputable resources because anyone can publish a blog or post to a forum or Facebook group inaccurate information. Many aromatherapy schools have free online courses about essential oil basics as well as advanced certification courses.
