Another French contemporary, Dr. Jean Valnet, used therapeutic-grade essential oils to successfully treat injured soldiers during World War II. He then went on to become a world leader in the development of respected aromatherapy practices. The modern use of essential oils has continued to grow incredibly rapidly as health scientists and medical practitioners continue to research and validate the benefits of therapeutic-grade essential oil.
“This study is a re-analysis of Centers for Disease Control and Prevention (CDC) data pertaining to the relationship of autism incidence and the age at which children got their first measles-mumps-rubella (MMR) vaccine. Statistically significant relationships were observed when African-American males were considered separately while looking at those individuals who were vaccinated prior to and after a 36-month age cut-off. CDC officials observed very similar relationships as early as November 2001, but failed to report them in their final publication. In addition, a relationship is seen when specifically considering children who received a diagnosis of autism without mental retardation. Although this was reported in the original 2004 paper, it was not discussed, nor was any follow-up study conducted. Preliminary results also suggest the possibility of a synergism between thimerosal exposure and MMR timing leading to a greater risk of autism.”
Diffusion is the process of dispersing essential oils so that their aroma fills a room or an area with the essential oil fragrance. Therefore, a diffuser is a device that diffuses the essential oil into the air. There are several types of diffusers available on the market in 2018, and many have reviews that may help you decide which one may be right for you, if you are interested in getting a diffuser.
I tested grapefruit oil from Eden’s Garden, tea tree oil from Tea Tree Therapy, and vetiver oil from Nature’s Kiss brand (I think the tea tree oil I bought in a natural food store and the other brands from Amazon?), all on the same strip of yellow construction paper. After 20 minutes, there is a huge oily spot from the Nature’s Kiss oil (and looking at the label, I can see now it is embarrassingly low quality production as it looks sort of cheaply homemade- don’t recommend ever buying that brand if you see it). The Tea Tree Therapy spot is smaller and a little lighter, but still definitely an oily stain. The smallest, lightest one is the Eden’s Garden grapefruit spot, which I’m sort of glad about considering most of my oils are that brand, but I can still definitely see where it was dropped. I can’t really imagine an oil not leaving any spot behind at all, but if I ever find one that does, I would be very impressed.
The importance of soil microbiology is vital to the plant and to the final harvest.EOBBD assesses the soil in which oil producing plants are grown in order to verify that the growing conditions are truly organic or wild-crafted. If the microbes are not measured at a specific ratio, this can indicate that the growing processes are not organic and the final yield may have traces of unwanted chemicals, pesticides and herbicides that can destroy the effectiveness of essential oils.
Ordered several from this company. The oils have hardly any smell at all. And are very watery, you try to get out a drop or two and the "oil" just pours out. I should've known by the price that these would be cheap but the reviews were mostly good so I took a chance. Now I regret it. You get what you pay for. Don't bother with these. And the shipping is extremely slow.
I keep reading comments about not Ingesting EO. I’ve researched young living brand EO and they are injestable. They are a therapeutic hospital grade. And their founder Gary young Takes many eo in capsules daily. Not all brands are. So I would only trust this particular brand because I’ve done the research on it. I know people who add YL lemon or grapefruit daily to water a drop is fine you don’t want to do more than that it can cause cramping and pain these oils are highly Concentrated. Make sure you do your research, for it is the only way you will be safe using these oils they are very powerful and in the wrong hands of someone who is not educating themselves can be very harmful. I attribute my nieces grades in school going up due to eo. They have helped her focus and help her attention. My moods have changes as well as my daily stress, anxiety and nervousness. I love eo and all they have done for my family.

USE ESSENTIAL OILS TO HELP YOUR MOOD. Lavender, peppermint, grapefruit, chamomile, lemon, ylang-ylang all help produce happy, joyous moods. Clary sage helps with PMS (although there have been reports that overuse of clary sage can lead to intoxication). Rosemary increases focus and concentration. Don’t forget the mood benefits of essential oils. Here’s an information packed aromatherapy reference chart to refer to.
Thanks for the informative article on essential oils! I want to know if there are any essential oils that can be applied on my skin (face) just before my skin is exposed to direct sunlight? I know that the skin where citrus oils are applied should not be exposed to direct sunlight for few hours after application. That’s the only question that I am concerned with because I am very interested in concocting a facial oil moisturizer after reading an article of yours that is about making a “3-ingredient facial oil moisturizer”.

Nat, I will back you on this. Young Living and DoTerra distributors are confidently spreading lots of false information on essential oils. I would trust Crunchy Betty’s information above over anything YL and DoTerra sellers say. A good friend of mine became entranced by YL a couple of years ago and is convinced that YL is the only company that sells “therapeutic” grade essential oils. As Nat says, do your research, read the best books you can find and caveat emptor.
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.
The pharmacist have the possibility to vote the “best pharmacy partner” within the “OTC-Studie” every year. Gold, silver and bronce medals are distributed in 52 categories. The “OTC-Studie” of the “PharmaRundschau” analyse which products or product families the pharmacies recommend the most to their customers from chosen OTC-indication groups. The reputation of a company and the business policy is for industry, wholesaler and service partner important in the eyes of pharmacies. That’s why the question after the company the pharmacies work best with and would recommend is an indicator for satisfaction of the customers with their market partner.

Getting in touch with customer service at NOW Health Group is a little bit less straight-forward. Their website lists all of their corporate offices (with phone numbers), but there is no one toll-free line mentioned for customer service or order inquiries. You can check online FAQ’s, fill out a product feedback form, or fill in an email inquiry form. For those of us who don’t like to deal via email, this could be the deciding factor between choosing NOW or another reputable brand that possibly offers easier access to talking to a real person. That said, NOW is definitely one of the bigger companies overall, and possibly they’d have huge call volumes if they opened their doors with a toll free line.

Of course aromatic materials were used in Biblical times for various medicinal, religious and ceremonial purposes but these materials would not have been essential oils, at least not by todays definition of being steam distilled products. This would have been impossible given that steam distillation had not yet even been discovered! Most people attribute the discovery of true steam distillation to a Persian scientist named Avicenna (Ibn Sina) in the 11th century. There was certainly no steam distillation over 2300 years earlier in King Tut’s time. Aromatic products used during these ancient times would have been of a crude solvent extracted nature using fats and pressed oils and the like and would not have been very concentrated (not to mention that extracted products yield very different chemistry than distilled products) and therefore their use cannot really be related to how we should use the steam distilled essential oils of today.


Standardized oils are not always clearly marked as such. Additionally, some essential oils are tampered with, also known as adulterated, in order to give the illusion that the oil is of an higher quality than it is, or to extend more costly oils in order to make more money on the sale of the oil. For example, the pricey Japanese citrus Yuzu Essential Oil resembles a combination of grapefruit and mandarin essential oils. Some sellers may be tempted to blend grapefruit and mandarin essential oils together and market the blend as the more expensive Yuzu Essential Oil. Patchouli Essential Oil is sometimes extended with the addition of less costly balsams or cedarwood. Lavender Essential Oil is sometimes adulterated by the addition of more linalyl acetate.


I am a part of a different MLM essential oil company that I trust very much. They have their own “standard” of quality which makes sense to me. They are clear in their communications that the standard is developed by them but tested outside the company (independent verification of their standard). One of the things they measure is the quantity of the various constituents of each oil. My understanding from them and other sources is that the constituents do need to be at a particular level or within a particular range in order to produce the desired benefit. Is this also “junk science?”
In Gas Chromatography, an essential oil is vaporized and passed through a long column to separate the oil into its individual components. Each component will travel through the column at a different speed, depending on its molecular weight and chemical properties, and is measured as it exits the column. Using this testing method, quality control analysts can determine which compounds are present in a test sample.
The Young Living Speech you give is completely inaccurate and part of the genius marketing used by YL. Oils that have “do not consume” are protecting themselves from lawsuits, it’s a reasonable label statement. I am an educator at a major US University teaching essential oil studies. I have worked in production and quality control of essential oils.

Take peppermint for example. Peppermint is distilled from the whole peppermint plant and is sourced indigenously from the northwestern United States. The ratio of the constituents menthol to menthone is used as a marker for high quality peppermint oil. Certified Pure Therapeutic Grade® peppermint oil should always have a significantly higher proportion of menthol because menthol has been shown to improve the beneficial value of peppermint essential oil. One study tested the cleansing properties of peppermint essential oil from three different species. Peppermint from Mentha piperita was demonstrated to have the highest cleansing properties, which was attributed to its high amount of menthol and low amounts of menthone. Conversely, the Mentha aquatica species was shown to have significantly lower cleansing properties and also had a lower amount of menthol and a higher amount of menthone. (Mimica-Dukić N, Et Al. 2003)
I have yet to come across a YL distributor who is a qualified aromatherapist. Not saying they don’t exist, I just haven’t met one and I check at every trade fair I visit. Possible that the reason you got vague answers from them is because they are preaching the company line that they have been taught without actually knowing/understanding the answer?
Recently, there was an article from Vanderbuilt Medical Center stating that the Tennessee Poison Center reported a doubling of children and essential oils exposure in recent years. The article did not state an increase in hospitalizations or side effects. Furthermore, I couldn’t find a source for actual numbers. (The full original article can be found here). Therefore, as soon as I read the press release and did my unsuccessful search, I contacted the reporter.
I’m not so sure that the FDA is always spot on with their statements–sometimes they tend to under–or overreact in they synopsis of what is healthy and what isn’t. However, if methyl salicylate is indeed toxic and they are moderating how much goes into packaging stickers, then should Wintergreen oil be consumed at all (or does the methyl salicylate become more neutralized when consumed with all the constituents of the oil)?

Thanks so much for your article. I am having a huge issue battling against the whole “therapeutic grade” malarky put out by several big name companies. It seems even though it is a subjective title, and many other similar titles like it are in fact trade marked, that somehow people just buy into the idea that it MUST mean the oils are better. I am a huge proponent of high quality oils and knowing the company, their standards, distillation processes etc. But these empty titles really drive me nuts! Thanks for your writings!
As far back as A.D. 1000, healers used mechanical presses or steam to extract essential oils from fragrant plants. Today, practitioners can rub oil-infused lotions on the skin, where the compounds are absorbed into the bloodstream. Or they can diffuse them into the air where, once inhaled, they bind to smell receptors and stimulate the central nervous system, says Joie Power, PhD, a neuropsychologist and aromatherapist who has taught nurses how to use the oils for decades.

Expressed citrus oils are produced by mechanical separation (cold pressing) of the oil from the peels of various citrus fruits such as orange, grapefruit, tangerine, lemon, lime, petitgrain and bergamot. Expressed citrus oils contain small amounts of naturally occurring nonvolatile residues such as waxes. Expressed citrus oils offer the advantage of cold process which results in an aroma which is identical to fresh citrus peels.
A third trademark has been registered (as a word mark) CPTG Certified Pure Therapeutic Grade also by DoTERRA Holdings, LLC, 370 W. Center Street,  Orem, UT 84057.  Filed on March 4, 2009, published for opposition on July 14, 2009 and official registration granted on September 29, 2009. This registration also has the disclaimer, “No claim is made to the exclusive right to use ‘certified pure therapeutic grade’ apart from the mark as shown”. There is a long list of products shown to be associated with this word mark.
As for blemishes and other skin irritations, there are plenty of options as well. Tea tree oil is an editor-loved remedy for shriveling up zits in a matter of hours, especially since it's one of the only essential oils (along with lavender) that can safely be applied directly to skin. Dab a few drops on a blemish to zap bacteria and soothe any redness. Got angry, inflammed skin from a sunburn, rosacea, or other sensitivities? Mist on some rosewater or a lavender hydrosol for instant relief. 
DaNelle started to take an interest in a healthier lifestyle after suffering from two debilitating chronic diseases. On a mission to create a farm of her own, DaNelle forced, or rather 'lovingly persuaded' her husband to purchase a ranch home on an acre of land and transform it into their very own urban farm. DaNelle blogs at Weed 'em & Reap where she writes about the sustainable backyard farming, traditional food, & natural remedies.
How do you know which are the best essential oil brands? After all, this is an industry that isn’t regulated by the FDA. Oil quality can vary based on the distillation process. It also matters if the manufacturer dilutes the pure plant oil with bases or additives. But many of the most popular companies do rigorous testing to prove their oils’ purity.
There were only a few things I was unhappy with, but they weren't important enough to lower my rating. First, I had to use a lot of cinnamon bark oil, and I mean A LOT, in my diffuser for it to really be noticeable. It's only been two weeks, and I'm three-fourths of the way through a 30 ml bottle! As others have mentioned, the oil comes out of the droppers really fast. You have to be extra careful. Lastly, I don't care for the residue that the cinnamon bark oil leaves in my diffuser. It has turned the inside a yellow, goopy mess, and I dripped the oil onto the front of my diffuser and it completely erased the ink to all of the words and numbers!
Thank you, Marcia!!! A friend asked me just this morning about the “Certified Pure Therapeutic Grade” oils she had seen, and my first question was “Certified by whom?” Mr. Wolfert may be correct in saying that the phrase is trademarked, and not to be interpreted that the OILS are certified by anyone, but the so-called “average user” is not going to know that. They are going to assume, wrongfully, that SOME official body has certified that DoTerra has the world’s most perfect oils. Somewhere on TV I saw the phrase “puffery”… Shame on any organization who has to stoop to such deliberately misleading marketing tactics to sell their product. Obviously the truth isn’t enough, some folks have to embellish and mislead.

A friend of ours recently became associated with doTerra and invited my wife and I to a “party” where doTerra sales reps talked about the benefits of EO’s and offered to sell various package deals or individual bottles of doTerra EO’s. They talked about the independent testing that doTerra has done by outside labs that they call CPTG (Certified Pure Therapeutic Grade). I came home and have been researching doTerra and Young Living on the internet (and believe me, I am skeptical of what I read on the internet), but I am very skeptical when companies make unsubstantiated claims about their products. I read doTerra’s testing protocol, but they say nothing about using an independent laboratory to perform the tests. Apparently there are no industry standards that apply to EO. doTerra is a MLM (multilevel marketing) company, kind of what I think of as a pyramid scheme, so their products are more expensive because there are many “middle men”. I don’t have a dog in the fight, other than my dollars, so I have spent several hours trying to educated myself about equally good products for less money. I settled on a company called Organic Infusions, and ordered a few of their oils, and when they arrive, I will compare with our friend’s doTerra oils and see if we can tell any difference. As for Young Living, Gary Young seems to be of very questionable character when you read about various schemes and scams he has allegedly been involved in. You can read about him for yourself by googling Gary Young quackery. I am not recommending the company that I ordered from, as I have not tried their products yet. There is a lot of information out there, Let the buyer beware!
Low temperature and low pressure play an important part of collecting the highest quality essential oil. When plant matter is placed into a chamber and steam is injected, the plant’s essential oil is released into the air. The steam and essential oil are carried out of the chamber and cooled. The oil and water are then allowed to separate for collection.
Most flowers contain too little volatile oil to undergo expression, but their chemical components are too delicate and easily denatured by the high heat used in steam distillation. Instead, a solvent such as hexane or supercritical carbon dioxide is used to extract the oils.[10] Extracts from hexane and other hydrophobic solvents are called concretes, which are a mixture of essential oil, waxes, resins, and other lipophilic (oil-soluble) plant material.
