I have never used either YL or DoTerra and am not affiliated with either company but I have some very serious concerns about the claims made by YL and their representatives, as well as their owner/founder and his moral standing. There are disagreements within the aromatherapy industry as to how oils can and should be used but I know several QUALIFIED aromatherapists and they all advise that NOT all oils should be taken internally or applied undiluted directly to the skin.
Thank you so much for this article! I am not really an EO user, I use a little to make soaps and cleaning products but nothing that would make me well educated on the subject. I have seen YL oils all over my Facebook newsfeed lately and my BS flag has gone off more than once after reading some of the advice, claims, and "testimonials". I don't debunk aromatherapy, I think it can be wonderful for some things, but the way this stuff is being pushed reminds me of the traveling medicine shows that sold snake oils and tonics. The reason I found you is one claim they are making is they have an oil/set of oils to "treat" Autism and as a parent of three Autistic kids with a basic grasp of physiology and pathology I know there is no science that can support that claim. The Autistic community is beginning to be the new "group to dupe" and I was working on a post for my blog as a warning for other parents and came across this. It so thoughtfully explains everything I could want to say that I would never have the time to research as thoroughly as you have. I am linking this post to the one on my blog. Also, I didn't know that you should not use them internally or undiluted. There is a whole lot of that going on with someone I know and I have been saying for some time that I don't know exactly what the dangers are but I know this is unsafe. Thank you again for the science and the information!
SMH at all of these Young Living Distributors saying their oils are the most pure and safe to be ingested. People, do your research please before being scammed by these distributors. There are third party sites that test the oils from different companies. Young Living oils are not more “pure” nor are they safe to be ingested without consulting a certified aromatherapist who is trained to know what amount of what oils can safely be ingested and by who. Some ages or people with certain conditions cannot ingest this or that oil. 1 drop of Lemon EO is equivalent of consuming like 1000 lemons. Young Living and Doterra and any other MLM company’s oils are more expensive not because they are pure but because they have to feed MANY mouths down the MLM chain. There are many companies out there that have pure oils without additives that are WAY more affordable. I am not a seller or a certified aromatherapist. I am just tired of all these MLM distributors spreading lies just so they can make a buck.

I'm updating this post years later to add important information. I do not have all of the information in this series on why I didn't choose certain companies so I would appreciate you not accusing me of coming to silly conclusions. I have gotten threatening emails (some of they cryptic threats), and have been warned about being sued if I published certain things.
I was introduced to doTERRA a couple years ago. As an aromatherapist with a strong aversion to MLMs, and particularly essential oil MLMs, I had many questions, doubts, and hesitations. But, I bought a few, started using them, asked questions, did research into their sourcing, and listened to people who knew the owners to glean what I could about their integrity and purpose. I worried about their encouragement of internal and undiluted use of the essential oils since I had learned that this was not acceptable, except by someone qualified to determine proper use.

I love essential oils! I use NOW Oils because they are affordable and easy to find. I think Young Living and DoTerra are over priced marketing scams. I tell everyone I use NOW. I have great success using the more reasonable priced oils and they even make some of their own blends. Highly recommend but everyone needs to find what brand works for them.

"...Lavender Oil, Lemon Oil, [and] Peppermint Oil" are drugs...because they are intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease. Moreover, these products are new drugs,... because they are not generally recognized as safe and effective for their labeled uses. Under sections 301(d) and 505(a) of the Act, 21 U.S.C. §§ 331(d) and 355(a), a new drug may not be introduced or delivered for introduction into interstate commerce unless an FDA-approved application is in effect for it. Your sale of the above-listed "Therapeutic Essential Oils" without approved applications violates these provisions of the Act. Furthermore, many of the conditions for which these products are offered... are not amenable to self-diagnosis and treatment by individuals who are not medical practitioners; therefore, adequate directions for use cannot be written so that a layman can use these drugs safely for these intended purposes." —FDA
TAOASIS works close with local manufacturer together which produce with loving handwork scent flowers, scent woods and vases. Especially products from german manufacturers are successful on the market at home and abroad. More and more customers are looking for a special quality, appreciate the transparent production process and the possibility to receive individual certificates.
I know 2 people who are part of the MLM’s, one YL and one DoTERRA. Through their websites I have learned of all this controversy and need to research. You did not answer AJ’s question. How much research is needed to feel qualified to use essential oils effectively and safely and get the most for your money. Should I take a course on them or are there on-line tutorials that are honest?

Hi there! I know in your list of 21 facts you said these oils should not be ingested…I have heard otherwise about a few specific brands. What were your true thoughts on this? Do you or have you used any oils internally? Or anyoneelse on here maybe? Really wanting to heal from the inside as well as using these topically. Thanks in advance! I’m still pretty new at this so any input or advice would be great!

I have been bothered by yeast infections in past yrs(vaginal) knowing that most essential oils have antibacterial properties I did the following; In 1 cup bottled water I put 8 to 10 drops Rosemary essential oil, stirred it up, wet a washcloth with it and bathed the area. I had immeadiate relief from the horrible itching. If it came back do it again..It only took 2 treatments for me. that was a Godsend to me.

As you can see, ingesting peppermint oil carries the risk of some serious side effects. If your essential oil sales rep doesn't mention that these are AT LEAST possible side effects, she's not giving you the whole story. And if you happen to mention it to her, she's likely to explain that those risks are associated with inferior and adulterated oils, like in the story that follows. But these are not the risks listed for inferior oils. These are the risks listed by the National Association for Holistic Aromatherapy regarding the ingestion of pure, unadulterated peppermint oil - for instance, the ones sold by Young Living that they instruct you to drop on your tongue, twice.
What you could do is use one of the safer mint essential oils as a flavoring. I have a great recipe for peppermint brownies and just made homemade ranch with Basil EO. If you have a highly tested pure oil than the therapeutic benefits are really great for using certain ones as flavoring in food or water. Always use a very pure oil that says safe for internal use on the bottle and that is on the FDA’s GRAS list. Peppermint is a great one to replace Wintergreen but Spearmint would also really work and has a more gentle effect in regard to its therapeutic properties.

Another important factor to know about the oil is the geographical location each plant was grown. Plants grow naturally and thrive in climates and conditions suitable for their health. Plants farmed in locations outside of their natural habitats will be less effective when distilled. The climate, the soil, the time of year (and sometimes even the time of day) have great effects on the quality of the essential oils and good companies know this.

I am still confused about this whole internal taking thing. how can several companies say their eos are 100% and yet some be safe to take internally and others not. also, I have been using NOW eos for a couple of years. you state that they are ok for cleaning but not for therapeutic reasons. can you explain this further? they say they are 100% pure and they seem to be working. would these other companies eos work better or differently? thanks
Thank you for the information you shared, it is great. Although, I am wondering why the company I am going through says you can consume their oils internally, and use it on your body as it is. Furthermore, I am informed that this company sells the purest form of oil out there. I found oils on Puritan’s Pride, and they say the oils there are 100 per cent pure. I certainly love their prices. I will be checking out the list you have above. I am new to this, so I need as much information as possible, and if you can help me with the above concerns, I will be so grateful. Thank you in advance.

Oral biofilm acquires new microbial species in each stage of its development, including Lactobacillus casei, Streptococcus sanguis, S. mutans, S. mitis and S. sobrinus, which due their pathogenicity could damage the enamel and gum tissue [3]. Diseases appear in this micro-environment when there is a lack of equilibrium in the ecosystem of the bacterial biofilm formed [4], and thus the mechanical removal of the biofilm is an important factor to prevention of caries and periodontal diseases. Since biofilm is an organized association, able to adhere to teeth and causing pathological alterations in oral cavity, its disaggregation is indicated as soon as possible [5]. Considering the importance of this dissociation, it is important to associate both chemical and mechanical procedures in order to control its formation [6].
Lortscher says that the purity of different EO’s can vary widely, based on the degree of concentration and where they’re sourced from. "On top of that, the quality of your oils can be affected by adulteration (the purposeful addition of foreign substances), unintentional contamination, inadequate production, or improper storage conditions," he says. "If you keep an essential oil exposed to bright sunlight or oxygen, the composition of the oil can change. It’s best to store them in a cool, dark place."
Contrary to what several essential oil companies recommend, the oils generally should not be swallowed, Power says. The body absorbs more this way, boosting the chance that they will interact with medications or cause an allergic or toxic reaction. Even continued exposure to small amounts (a few drops a day in a water bottle) can lead to fatigue and headaches. Taking in larger amounts of certain oils -- like tea tree oil, wintergreen, and camphor -- can lead to throat swelling, a racing heart, vomiting, and even seizures, says the Tennessee Poison Center, which saw the number of toxic essential oil exposures double from 2011 to 2015.
I’ve seen many comments about using Lavender neat, mainly, on children. Just in case anyone is interested in this case study and research about Lavender and Tea Tree oils causing gynecomastia in boys. YL nor DoTerra could get me to even take a chance on using any oil neat after reading about this. Essential oils are great, but can be dangerous, no matter the maker.

I have enjoyed reading the continued conversation on this thread. Thank you, Lindalu for your comment about YL not training their people in aromatherapy–but just their version. I have been frustrated about the same thing, as I am beginning to realize that there are a bunch of rookies all around me (myself included), that are almost mindlessly using YL essential oils–even in potentially harmful ways–without having a clue as to what makes them tick!
In any form, using essential oils as green pesticides rather than synthetic pesticides has ecological benefits such as decreased residual actions.[30] In addition, increased use of essential oils as pest control could have not only ecological, but economical benefits as the essential oil market diversifies[29] and popularity increases among organic farmers and environmentally conscious consumers.[28]
