All absolutes are prepared by first extracting the oil from the plant matter using the solvent hexane. This solvent is then evaporated and removed via a stripping distillation process to typically less than one part per million (ppm) remaining, producing what is called a concrete. This concrete is a combination of the plant’s essential oil as well as co-extracted plant waxes. The essential oil is separated from the concrete by ethanol, leaving behind the plant waxes. The ethanol is then actively removed from the remaining material in a second evaporation process, separating the essential oil portion, which is now called an “absolute.” Residual ethanol is typically less than 1 ppm in the absolute material.
Since we are not chemists, nor do we have the resources or equipment to evaluate the chemical purity of the essential oils, we stuck with methods of evaluation available to the average consumer. Out of the nearly 40 different essential oil companies researched we were able to narrow down the list to a total of seven reputable companies by using the parameters listed above in our section ‘What to look for when purchasing essential oils.’
"Essential oils are incredibly concentrated and should always be used exactly as recommended," said Elizabeth Bloom, homeopath and founder of Elizabeth Essentials. "They are far more potent than dried herbs - approximately 75 to 100 times more concentrated. A large volume of plant material is needed to produce small amounts of a distilled oil - 220 pounds of lavender flowers, for example, is required to make 1 pound of lavender essential oil."
Many essential oils companies sell their EOs undiluted, so you’ll have to dilute them yourself (NAHA provides some guidelines on safe dilution). Adults should dilute an essential oil anywhere from 2.5 to 10 percent; for a 10 percent dilution, for example, you'd use 60 drops of essential oil per ounce of carrier. Some of the most common carrier oils are jojoba, coconut, and sesame oil.
Essential oils on the market were analyzed using GC-MS and the main ingredients of each essential oil were quantified. Analysis of the essential oil of Lavandula officinalis (lavender oil) showed that each sample had a different ratio of the contents of main ingredients, such as linalool, linalyl acetate, and camphor. In addition, some commercial lavender oils were analyzed by GC-MS for comparison with the Lavandula flagrans (lavandin oil) and the reference standard. As a result of this analysis, although the components of almost all commercial lavender oils were approximately the same as those of the reference standard, there were a few products that contained more than 0.5% of the amount of camphor in lavandin oil. This suggests that some lavender oil samples are mixed with lavandin oil to lower the price. Commercial essential oils of Melaleuca alternifolia (teatree oil) and Mentha piperita (peppermint oil) were also analyzed by GC-MS. Each of the peppermint oil samples had a different ratio in the content of its main ingredient. With respect to teatree oils, the amount of terpinens in each sample differed. These results led to concern about the efficacy of essential oils. For achieve the expected efficacy of essential oils, correct information on their ingredients should be available and quality control using instrumental analysis should be introduced.

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.
Fragrance oils often have additives or are entirely made of synthetic chemicals intended to mimic natural scents and extend the lifespan of the scent vastly. While a fragrance oil may be used in a perfume to help the scent last all day, or used in a candle to scent a whole room, essential oils are extremely volatile, meaning they evaporate quickly. So using only essential oils in perfumes, candles, soaps, and sprays most often results in scents that don't linger very long. Because of this, perfumes and other scented items often use natural and/or chemical additives to enhance and extend their tenacity, or scent life, thus making them fragrance oils. They are then labeled as such.
Holly is correct on the words! One of the best ways to tell if oils are safe and pure is if the common bottles do have “do not consume” or a similar statement on them! I don’t care what the distributor or customer care person says! I have tried over 10 of the top companies oils and all but one has said do not consume. That is a key for you to know the purity. I am allergic to petrochemicals so many I find have them in them! Many of the other dry out the back of many hand. Pure oils should do neither of those. One of these day I will have to do a video for you tube to show this reaction and the brands that do that!
I really appreciated reading this article. I am Young Living distributor and chose this company after a lot of reading about essential oils. I chose them for the variety of products they carry and their open commitment to quality. There were definitely other companies that I trusted, but I'll be honest I like the idea of supplementing my family's income too.
"Therapeutic Grade" or anything along these lines is another common term used to describe "top quality oils". It sounds legit, but it is a marketing term that I am guilty of having used myself in the past when talking about oils. I thought it meant something. There isn't a therapeutic standard for essential oils so the name and any emblem associated with it is virtually meaningless. It's a self-regulated claim like many other healthwashing terms. Cropwatch explains here.
I love do terra oils. I have been usining the oils and suppliments internally, neat, and with carriers for over 5 years now. I haven’t died yet, nor my kids or extended family. Network marketing is a great way to market essential oils, because you want to talk to people face to face about the oils and how to use them. There are several companies that I’m sure offer quality essential oils, for me , Doterra has been sufficient for my needs, and I trust the company.
Simple smells such as lavender, chamomile, and rosewater may help keep you calm. You can breathe in or rub diluted versions of these oils on your skin. Scientists think they work by sending chemical messages to parts of the brain that affect mood and emotion. Although these scents alone won’t take all your stress away, the aroma may help you relax.
The aroma of an essential oil can be a good indication of its purity and quality. The more pure an essential oil, the more powerful the aroma will be, and the more it will be able to elicit the response that you desire without being overwhelming to the senses. The plants we use to extract our essential oils are grown in nutrient-rich soil with ideal conditions such as air quality and precipitation. They are also harvested at the peak of their quality to ensure a rich, aromatic essential oil. These methods guarantee that the fragrance and quality of our oils will exceed that of synthetic or diluted oils, even those that claim to be “natural” or “pure.” In addition, each oil used by ZEVA is tested using gas chromatography to insure it contains the active phytochemicals and to insure maximum potency.
One thing I like about Rose Mountain and Organic Infusions is that I can get 30 ml bottles for the EO’s that I use most frequently. They also, both, have a large selection of other products and I’ve found their oils to be good quality. Organic Imfusions labels its products as Certified Organic or just organic, meaning the farm hasn’t been certified. Rocky Mountai Oils has a good selection of oils and blends but not a lot else. Some of their singles I really love but I got a peppermint that smells like cat pee to me. For what it is worth, I still use all 3 of these companies.

More importantly, the founders and owners of the companies will have personal relationships with the farmers so they can be certain of what they are getting. There are many tiny, locally operated farms around the world who can’t afford the extremely high costs of organic certification, yet they still practice organic farming which includes: no use of chemical pesticides, herbicides or fertilizers, no genetically modified seeds, and healthy crop rotation to protect the soils. That is what is meant by Unsprayed.
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.
They're made from parts of certain plants like leaves, herbs, barks, and rinds. Makers use different methods to concentrate them into oils. You may add them to vegetable oils, creams, or bath gels. Or you might smell them, rub them on your skin, or put them in your bath. Some research shows that they can be helpful, if you know how to use them the right way. Always check the label and ask your doctor if you’re not sure if they’re OK for you to use.

d?TERRA does not claim that the FDA, AFNOR or ISO has certified, registered or somehow approved its essential oils. Although AFNOR and the ISO have monograph standards for certain plant extracts in different industries, it is my understanding that they do not have standards for grades of essential oils. In fact, there are no current regulatory standards for the use of the descriptor “therapeutic grade” in the industry. Anyone can use the term to describe their essential oils regardless of their purity or potency.
Yes, many companies do GC/MS testing and infrared. The real test is, what do they compare the results to and what is that company’s standard for what a good oil is? If their standard is high, then they may reject oils which are below that standard. If their standard is not so high, then they will accept and sell more oils, even ones that have been rejected by a company with higher standards.
At the beginning of your article you state that Young Living Representatives suggest that diluted EO's are ok to ingest and then your article goes on to talk about sales people suggesting ingesting EO's in their consentrated undiluted form is ok. That is confusing to me; it's obvious you don't believe ingesting highly potent EO's and your beginning statement shows that Young Living agrees. If a representative has a memorized statement it should be in line with your opening statement from Young Living suggesting dilution; if they say otherwise they are speaking for themselves.

There are at least 30 + single plant essential oils that can be applied neat ( straight or undiluted) a far cry from a few. Most of the rest only need approx 1 to 1 dilution. Again the same goes for undiluted oils for babies and children. Now naturally their skin is more sensitive so you need to be more watchful and careful and possibly only place these oils on a babies feet and use a 1/4 to 1/2 drop of the oil instead of the full dose.
There is a Cinnamon essential oil, however the flavoring kind you get at a grocery store is not an essential oil in that it isn’t therapeutic grade so it has no therapeutic benefits. Many of these are made with synthetic oils (though not all of them) that just taste like what you want and all of these kind of oils have lots of filler oil like the sunflower oil. This does make it ok that you are using so much though. 🙂 If it were real therapeutic grade essential oil that much of it would be such a strongly concentrated flavor that you’d cut back to a drop or two really quick. It also would be an unsafe health choice to take such a large dose of any therapeutic grade oil no matter the type, source, or purity. I do hope that it helps anyway, but I can vouch for the pure therapeutic grade cinnamon along with lemon EO helping control my blood sugar levels. I love essential oils. Aren’t they great?
This is a good starter kit, especially if you don't want to spend a fortune on something that may not be your thing. We don't use all 6 of these, so I'm glad I didn't get suckered into buying a more pricey brand. I've purchased expensive essential oils and less expensive ones like these, and these are a good value. Don't get caught up buying multi-level marketing brands like **terra, just buy what works for you and your budget and enjoy!
Not all essential oils are created equally, nor does more expensive necessarily mean “better.” There are certain brands I will use in a less therapeutic fashion (like for cleaning), because they’re far less expensive than their counterparts. When you see a wide fluctuation in price between, say, lavender essential oils, you can bet that the far less expensive one is likely lower in quality.
Specific essential oils are used to treat certain conditions, though exact types of oils used and how they are combined varies depending on the experience and training of the aromatherapist. (The National Association for Holistic Aromatherapy (www.naha.org) and the Alliance of International Aromatherapists (www.alliance-aromatherapists.org) are two organizations that have national educational standards for aromatherapists).
I could tell you that I am experienced with essential oils for 7 years or I could be a first time user… if it makes me any more or less credible. Either way, I spent my last 6 weeks deliberating between Young Living and doTERRA essential oils. I looked up as much as I could take in on both companies. I attended each of their classes and took the “Pepsi Challenge” smelling and applying each company’s oils. First, I started with each company’s Lemon essential oils. Closed my eyes, shuffled them between my hands and smelled each. Without knowing which one was in either hand, I noticed the first one smelled good. Ok, it was definitely a lemon aroma. Then, I smell the second one. It too, smelled great. I liked them both, at first. As I went back to smell the first one again, I could tell something wasn’t quite as fresh as the one I smelled a second before. It had a little more of a pungent aroma. As if it were not as clean as the second. Maybe even a weaker or diluted feel. Maybe as if it were not as pure as the second. Upon opening my eyes, I saw the first one was Young Living’s product and the second was doTERRA’s. It was clear to me which one I liked better. So, I tried it with a few more oils from both companies. I did the same with each Lavender, Thieves/On Guard, Peppermint, and Frankincense. One after another, it was consistently doTERRA’s oils I honestly felt had a better, more cleaner, more purer smelling aroma.
The results obtained for MIC/MBC/MFC of the EOs against the oral microorganisms are shown in Table 2. According to Duarte et al. [17], the EOs presented strong to moderate antimicrobial activity against planktonic cells, with MIC values between 0.007 and 1.00 mg/mL. The highest activities were observed for A. speciosa, C. sativum and C. zeilanicus EOs against C. albicans (0.07 mg/mL). Coriandrum sativum oil inhibited F. nucleatum and S. mitis at lowest MIC values (0.015 mg/mL and 0.062 mg/mL, respectively) compared with the other oils tested. S. guianenses and M. glomerata oils inhibited, respectively, the growth of P. gingivalis and S. sanguis at 0.062 mg/mL.
Purity is a major issue when using essential oils, particularly if you are using them therapeutically, internally or topically.  The most important issue is to know your company.  What type of testing do they do?  Do they test all batches?  Are the oils grown indiginously?  How are they harvested?  If your oil company cannot answer these questions to your satisfaction, then use another company.  In my opinion, there are a few companies that have consistently high quality oils.  Good luck!

The problem with dermal sensitization is that once it occurs with a specific essential oil the individual is most likely going to be sensitive to it for many years and perhaps for the remainder of his/her life. The best way to prevent sensitization is to avoid known dermal sensitizers and avoid applying the same essential oils every day for lengthy periods of time. Sensitization is, to an extent, unpredictable, as some individuals will be sensitive to a potential allergen and some will not.8
First, we are not an MLM company and don’t need those outrageous margins to pay a bunch of middleman distributors. Second, ZEVA was founded by Dr. Tracy Gibbs, a world-renowned pharmacognosist who has dedicated his life to the study of chemistry, hematology and botanical medicine with a goal of finding the right balance of natural products that will enhance consumers’ lives and offer profitable business opportunities to retailers. Dr. Gibbs and the executive team at ZEVA Essential Oils are a group of hard-working, honest business professionals committed to offering only 100% ISO certified essential oils, so consumers can trust the products to be the highest quality, and consultants can have confidence in the products they sell.
In the holistic use of essential oils, the focus is on bringing the body back into natural balance and harmony. Disease is seen as merely an outward symptom of a deeper, underlying imbalance in the body, mind and spirit. Holistic medicine sees the body as a self-healing mechanism. The body is capable of healing itself of disease by bringing the whole person back into balance. Therefore, the holistic use of therapeutic essential oils focuses on restoring balance in the body, mind and spirit. Success is gauged equally on the relief of symptoms and the improvement of overall wellness, vitality and happiness.
The oils from Marshalls you mentioned stated they are for aromatherapy. These are fragrance oils and probably NO T pure. That’s why they are so much cheaper 🙂 and they are just for enjoying the scent vs. therapeutic benefits. I would not recommend applying them to your skin in any way but the DoTerra oils you bought can be applied once mixed with coconut oil (fractionated will not harden in cool temps), sweet almond oil, argan oil or even olive oil. Any oil you choose should be labeled organic of course

Ingesting essential oils for health benefits has been prescribed for centuries by experienced professionals. This process, when administered safely and correctly under supervision, can have profound healing effects on your body with issues like digestion, immune defense and hormonal imbalances. However, ingesting the wrong oils — or even the right oils in the wrong portions — can have disastrous and permanent effects on your internal tissues and overall health, and worst of all, you may not even realize any damage has been done until decades later in your life.
Plus, I don’t care how wonderful an EO is, I don’t think a certain combo is going to make someone “Thankful” or give them “Couraqe.” Those are personality traits, not a response to treatment. Seems a bit hokey to me. I just gave her the catalog back and didn’t say much. The MLM system is designed to make people antagonize their friends into feeling obligated to purchase stuff.
You may be asking yourself, “so, which brand would you recommend I buy, Christina?” and that would be the same question that I was asking myself.  With all of these brands telling me that theirs was the best, I wasn't sure which brand to pick. I had been using Now Foods essential oils and Aura Casia for quite awhile and was seeing success with these brands. I was curious if these more affordable essential oils are working so well, how much better would the “high-end therapeutic grade” essential oils perform?
Most citrus peel oils are expressed mechanically or cold-pressed (similar to olive oil extraction).[citation needed] Due to the relatively large quantities of oil in citrus peel and low cost to grow and harvest the raw materials, citrus-fruit oils are cheaper than most other essential oils. Lemon or sweet orange oils are obtained as byproducts of the citrus industry.
