Have you ever wondered, “What are the best essential oil brands”? Who should you buy your essential oils from and why? Those are very good questions! There are variations in quality, standards of production, company culture, price, and product selection among many of the popular essential oil brands available today. I want to highlight what sets apart one essential oil company over another, and which ones would be the best essential oil brands to start buying from.
Second, don't assume you can use an essential oil for flavoring anything you're going to eat unless it's either food grade (usually labeled and more diluted to prevent injury), has been inspected by the FDA (these will have a nutrition label somewhere), or you know the oils are 100% pure with no additives and you know how to appropriately dilute them to make them edible. If there is no FDA label, there is a good chance that the oil is not 100% what it says it is - it most likely has some additives that are probably best not to consume. For these oils in particular, I personally would not consume them, despite the fact that the labels say they are 100% "insert oil here". The fact that the label specifically says "for external use only" helps that decision :P
Essential oils are widely used in food flavorings, and many of our foods naturally contain them anyway. So small amounts – up to one drop – are not a huge issue, thohg you still need to be aware that gastric irritation is a possibility, so make sure the oil is properly dispersed in whatever the food or excipient is. Taking oils is water is a no-no for this reason.

The purity of an essential oil is its most important characteristic. An essential oil that isn’t pure means you run the risk of putting germs, heavy metals, or adulterants onto or into your body, which can provoke irritation, adverse effects, or even sickness. Without an accepted standard for essential oil quality, doTERRA created its own testing process, calling it CPTG Certified Pure Therapeutic Grade®. The CPTG process certifies that there are no added fillers, synthetic ingredients, or harmful contaminants in their essential oils that would reduce their efficacy. doTERRA even goes a step further, putting all their products and the packaging through a battery of tests to ensure a long and effective shelf-life. This protocol ensures potency, purity, and consistency batch to batch.
FDA regulations state that natural product labeling, including all website claims as well as product label content, cannot legally suggest that a product intended for topical or aromatherapeutic use be taken internally without labeling the product as food. NOW Solutions closely adheres to all federal regulations. See more Essential Oil Food Grade FAQs.

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.
Also, if you drink it, you should only use a glass or stainless steel container. Glass is highly preferred over the two and the easiest for cleaning out of the previous EO. The smell/taste of an EO tends to “linger” a bit. This is usually a good thing I would think in say aromatherapy but in this case not so much…unless of course you prefer to use the same EO each time.
The truth is that there are MANY therapeutic grade standards. The problem is, which one do you trust? It’s important for people to realize that all of these standards are INTERNAL standards developed by companies selling oils and may or may not include quality control by a third party lab. Furthermore, if a third party lab is used, does this lab really know what they are doing? It’s also important to know what the company defines as being “therapeutic grade” does it simply mean that the oil is pure or does it mean something beyond purity and carry with it a quality standard as well? Let’s face it, an oil can be pure as the driven snow but still be low quality, I see this on a daily basis in the samples I analyze for my clients in order for them to make good buying decisions. Judgments about essential oil quality take more than just good chemists and good equipment, they require many years of experience in odor evaluation and knowing what specific minor components are desirable in an oil and not just focusing on the major components.
Let’s be clear that my beef isn’t with the product – it’s the misleading marketing done by the MLM’s that has led to their gross misuse. Essential oils are fantastic and their biggest benefit is when they are used in an olfactory sense – that is inhaled and smelt. Diffusing essential oils works wonders for stress, anxiety, and moods. Using diluted oils on the skin can be great for relaxation, to relieve pain, reduce inflammation and just to smell nice! They are a very powerful medicine and when used in these safe and non-invasive ways can help to balance the body and promote healing.
“In a base of…”. Unfortunately, many companies will use an extender oil like almond or safflower oil as a base to dilute the essential oil in order to cut costs. This creates a slower acting oil, and one that is much less effective for many uses. Extender oils can also become rancid quickly, reducing how long the oil will last. Even if a high quality base oil is used, diluting the original essential oil limits how you can use the oil.

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.

Unfortunately, this ignited and resurfaced some of the studies that are often quoted regarding the toxicity of essential oils and children. These sources for toxicity where some of the very same ones in which I reviewed and discussed the caveats to here. The sources that are referenced by the poison center also were lacking in some information I was seeking. They do not include the essential oil company, quality of the oil, and some where related to one isolated or synthetic constituent. The parts of an essential oil are not the same as the synergy of the whole essential oil.
Kendra Kirkham wrote a really great article a few years ago for the IFPA Journal “In Essence” about the lack of any formal essential oil “grading” system for aromatherapy and provided clear information about the topic, as well as explain the use of the words “therapeutic grade” as a marketing tool for a certain MLM essential oil company. It’s a shame that many others now elect to coin the bogus term. I understand the thought is to express that their oils may be of higher quality or perhaps used in clinical settings, but use of such terms only adds to consumer confusion. Thanks for bringing this to the attention of the masses.

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.
Essential oils can have multiple benefits - and multiple oils can benefit similar conditions - so it may be easier to start with a pre-made blend, experts said. Many companies - including Elizabeth's Essentials (available locally at Earth Savers) and Young Living essential oils - offer a variety of blends of oils specifically formulated to treat a broad range of conditions ranging from arthritis to sleep to anxiety.
You seem to be a bit touchy about research. I would suggest that you go to PubMed and search for “essential oils.” You will definitely find some scholarly research that has been published on the subject….but not nearly enough. (If you need a comparison, do a search for your favorite pharmaceutical drug). Given that publications are the currency for academic research, this would suggest that there aren’t as many researchers studying these essential oils as you seem to think.
If you are seriously interested in diving into the world of essential oils, get trained. Start with a workshop in your local area taught by a trained aromatherapist. Whether you are using the oils purely for personal use or really want to get into the business of selling oils and sharing your knowledge, unbiased aromatherapy training from a certified aromatherapist and/or herbalist is invaluable.
I really like DoTerra brand essential oils. I have many of them and find them high quality. All essential oils that are sold are in business. Whether it’s MLM or not. I don’t have a problem with that at all (but maybe it’s just me). Young Living was once considered by many to be the “best” but now that DoTerra’s been on the market (I don’t know, maybe five years or so?) they have competition. Apparently people from Young Living (I’m not sure if that’s the name) broke away and started DoTerra. In any case, if it’s purity and therapeutic grade I personally think both are good companies. Some like DoTerra more so that’s what got me started on them.
Some essential oils qualify as GRAS flavoring agents for use in foods, beverages, and confectioneries according to strict Good Manufacturing Practice (GMP) and flavorist standards.[48] Pharmacopoeia standards for medicinal oils should be heeded. Some oils can be toxic to some domestic animals, cats in particular.[49] The internal use of essential oils can pose hazards to pregnant women, as some can be abortifacients in dose 0.5–10 mL, and thus should not be used during pregnancy.[citation needed]
Tomato Leaves are toxic, never ingest them or use for skincare products. Strictly aromatic purposes are okay, like candles, however, Tomato Leaf EO or Absolute is very expensive for such a venture. The fresh leaves loose their wonderful aroma once dried, I tried it already 🙂 Best choice will be a fragrance oil if you want to really capture that smell, I know…not natural, but these are the facts. Good luck!
I myself have a preference for a particular company because of my own personal results and the consistent reports of my clients. I am also passionate about quality due to the way I use oils. I do stick with what has worked for me and my clients consistently. However, when reporting the information on this blog, I try to keep the facts and put my experience and company suggestions in a separate section and on a different website clearly delineated.
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.
In conventional research studies, it is important to be able to determine exactly what caused the outcome. In essential oil therapy, the oils are sometimes applied with massage, which makes it difficult to tell whether or not the outcome was due to the essential oil alone, or the massage, or the combination. Also, essential oils are composed of hundreds of chemical constituents, and it is hard to determine which ones may have produced the desired effect.
Flower blossom essences are in a class by themselves!  Many flower essential oils are produced by chemical extraction, however we are grateful to have several  which are produced by steam distillation (Rose and Neroli). As a group, flower blossom essences are extremely heart opening and are powerful, natural aphrodisiacs.  They show us our greatest potential and they show us the power of acting from a place of love.

Actually John, that isn’t entirely true. Unlike many products EOs are not required to list everything that is in them. Some grocery and drug store brands of EOs come already diluted only this isn’t mentioned on the bottle. You can unknowingly over dilute your EOs by adding additional carrier because you think the product you have gotten from the drugstore is pure.
Essential oils are all the rage. You know the ones I’m talking about. In fact, you’ve probably been invited to a product party where little vials with expensive price tags promise a wide range of health benefits. You’ve also heard the stories. Essential oils cure warts and ear infections. They soothe rashes and bellyaches. They reduce fever and fight the common cold. Virtually any ailment you suffer has a corresponding dose of liquid magic.
Myrrh has been used in rituals, anointing blends and perfumery since ancient times, and was felt to enhance spirituality during sacred rites. The oil has a rich and warm, woody yet bittersweet scent which is pleasant to use during meditation. We offer a premium quality Myrrh, and a more cost-efficient selection from India that is softer and sweeter, to cover your product needs.
First and foremost, the grading systems companies use to grade their products are all relative because there is no regulation of the grades. So when it says "therapeutic grade", that just means it's that companies idea of therapeutic grade. That's not to say they are misrepresenting their products, but there will be variance between products because there is no standard, so finding a brand you trust is important.

One example of oil that shows some evidence of effectiveness is tea tree oil, which may be an effective treatment for acne, according to the NIH. In one clinical trial, researchers compared gel containing tea tree oil to a benzoyl peroxide product, and found that the benzoyl peroxide worked slightly better but that the tea tree oil had fewer side effects, according to the NIH.
In the world of essential oils there is an enormous amount of controversy and competition, with some companies accusing other companies of being less pure, while others claim trademarks and exclusivity on their products. All of this noise creates plenty of confusion for the average consumer to sift through, especially since there is no official regulation or oversight on the essential oil industry, federal or otherwise.

I have read quite a bit about YL and DoTerra and several other companies. The information available seems to suggest that Mr Young (founder of YL) is of questionable repute and has been caught out as a fraud selling a few different “natural” healing methods in the past. The people who founded DoTerra used to work for YL but were fired (or chose to leave) when they began to question YL practices, including the establishment of the Ecuadorian processing plant. No accusations were made but there were implications that perhaps what YL are actually doing is not aligned with what they are preaching. I was very interested to read the earlier comment that YL oils left stains on construction paper using the testing method suggested in the article.

One thing I wonder though (couldn’t find it on the websites you listed either) – My grandmother loves the smell of tomato leaves and I ran across a hand cream that was tomato leaf scented once when I was overseas but it was too much liquid to bring home. Is there somewhere I can find an essential oil or make one or something like it to make a nice handcream for her?
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!
They are actually a very dark shade of violet. We are proud to use patented premium violet glass bottles that offer the greatest degree of protection from the damaging UV rays. Timeless and protective qualities of violet glass are traceable back to the ancient Egyptian civilization, when valuable essences and healing elixirs were kept in gold and violet glass containers. The unparalleled quality of our bottles ensures freshness and gives our oil an extended lifespan. Like a fine wine, some oils age gracefully when encased in violet glass walls.
Hi Robert – I know I’ve read that more than a few times in some of the main stream aromatherapy books and think I was told that in my aromatherapy classes – about the 2% thing. So, it is a perception that I myself also have and have, therefore, spent long hours trying to determine if my sources are selling me what they say they are and who my sources should be – long hours and dollars spent to attend conferences to rub elbows with those who should know. However, at that time in 2006, organic essential oils were not readily or at all available. I have also read and have been told by those who should know, that just because an oil is certified organic, there is still no guarantee that said essential oil is not adulterated or for that matter really organic. The argument that I was given was that no one stays around to make sure that the material actually placed into the still was the same that was grown in the organic soil. We live in a world of distrust and for good reason as we look around at the greed in high places. I know this doesn’t address your issues about your article but was and always will be interested in any discussion concerning what constitutes an unadulterated oil. That being said, I would think there are certain things to consider when purchasing an oil and the chances it may or may not be adulterated. Some oils are naturally inexpensive and there would be nothing gained by adulterating them. If you look at how many acres of a particular oil are said to have been grown for a particular year and for that same year there was a great more essential oil sold than could have been produced – then you know you probably have an issue. I know that you know far more about this issue than I do, but I would like to see more discussion concerning what things would throw up a red flag when purchasing an oil from a particular supplier. The internet is now so absolutely full of people selling essential oils and copying and pasting the same old information that it is a bit overwhelming. My concern is the same as other clinical aromatherapists and that is that people will try a particular oil, find that it doesn’t work because it is either adulterated or the person selling the oil really doesn’t have a clue which oil or chemotype should be used for a particular purpose, so the client then assumes that any and all claims made by the aromatherapy industry are false or vastly overstated. This is true in research studies that have been done as well. Is there an answer? I would like to see an article by someone as knowledgeable as yourself that gives you a list of possible red flags and things to consider when looking for suppliers, particularly bulk suppliers.
Ok I don’t usually make comments on articles but I just had to on this one. To the author: I’m sorry but this blog is poorly researched and full of errors. If you are going to put out information that people take as truth or at the very least as suggestions because they like you, you need to know what you are talking about. I highly suggest you take this blog down, re research essential oils and rewrite one that is accurate.
Lavender has been used for over 2,500 years. First by the Egyptians as a perfume, it was later discovered to have many other benefits. It was first commercialized to the United States and Canada when it was sold by the English Quakers. Today there are countless countries around the world that participate in the production and almost every nation in the world has their own uses for Lavender Oil.
In the article above this blog there is a link that will take you to 19 essential oils that can be used on babies and children. I looked at it, and the URL is http://www.abundanthealth4u.com Everything I have read about using essential oils on children stresses the importance of proper dilution. Be careful if you decide you want to do this. The word “therapeutic” is tossed around like pizza dough, and it really doesn’t have a scientific meaning when applied to EO’s.
It is important to know exactly how the oils were extracted. As we discussed earlier with how essential oils are produced, specific methods are required for specific plants. A good essential oil company will declare the method used for each individual oil. If you don’t see any method of extraction, or you find a blanket statement saying that all their oils are steam distilled, be wary, they could be fake.
Used the right way, they can help you feel better with few side effects. For example, you may feel less nauseated from chemotherapy cancer treatment if you breathe in ginger vapors. You may be able to fight certain bacterial or fungal infections, including the dangerous MRSA bacteria, with tea tree oil. In one study, tea tree oil was as effective as a prescription antifungal cream in easing symptoms of a fungal foot infection.

Hi Linda! Just wanted to let you know that NAN oils are amazing! I have been using them for quite awhile and there is no comparison to any health store oils or most online. It’s fortunate that there is so much info out there today about EO’s as I bought the book that’s listed, “The Compete Book of Essential Oils and Aromatherapy” when it came out in 1991! That was before I even knew about the internet! Just a few things to keep in mind: NANs kits are a large collection and also 15mm, that’s why they seem so expensive. You can always buy just what you want, even in a 5mm. Nice size to try if your unsure. Also, do your OWN research instead of listening to sales pitches from paid representatives. A high percentage are gullible parrots. But to each their own. Just keep reading about EOs as you can never learn enough! I almost actually hate to bring this up, just remember I am NOT paid for indorsing – Read the articles in her blog, “wholenewmom”, about comparing EO companies. She really spells out differences between a lot of the well-known companies & what to look for in any. It’s Very informative! And I was blown away at the conclusion. Good Luck and Be Well!
In the United States, aromatherapy is regulated by how it is intended for use: cosmetic, drug, fragrance, food additive for consumption, or “something else.” Therefore, if a claim is made by any natural substance or an essential oil that makes it appear as a drug, and it hasn’t gone through the FDA approval process for this, the claim is in violation of the drug standards. (This does not imply that the oil itself is unsafe, rather, that the proper protocol for approval was not adhered to.)
#1 – It seems to me that Dr. Pappas endorses your favorite brand, since this is the brand Danielle uses (and there’s a $50 coupon for your favorite brand on this page!). I’ve read a bit about the bad blood between your favorite brand and Young Living. Are both companies legit w/o putting adultered oils on the market? Or is Young Living not as good a company in your opinion?
At NOW® we’ve established long-standing relations with our essential oil vendors, and we purchase our oils in large quantities that qualify for bulk discounts, which we then pass on to consumers in the form of everyday low pricing. We also sell direct to retailers instead of going through distributors, which can add as much as 30% to a product’s cost.
Because essential oils are obviously all-natural, it might be easy to assume that they're gentle and largely unreactive. This isn't the case at all—by definition, it's extremely potent stuff. "On average, they are up to 75 times more powerful than dried herbs," says Avery. As such, "essential oils must be handled with care." This means that a couple drops go a long way, and aside from very specific oils (more on that later), essential oils should always be diluted properly before applying them directly to skin. Whether or not essential oils should be ingested is actually a highly debated topic, and many argue that it isn't safe unless specifically advised by a doctor or expert.
These scents are all wonderful. And they are all strong enough that if you sniff them out of the bottle they may singe your nose haha. My favorite is probably sweet orange, but they all have useful medicinal purposes. If anyone in my house gets a head or chest cold I am sure the eucalyptus will be used. The peppermint seems to have a positive impact on my sinuses. I actually just used some of the tea tree oil for a hair and skin care recipe using olive oil and essential oils. It worked out very well, especially for my skin. I tend to have very dry, irritated skin in the winter time, and lotions just don't seem to help for very long. I started using olive oil and then thought, why not try adding the essential oils in the recipe? You can tell the difference between just using olive oil versus using olive oil mixed with this tea tree oil. Therefore, while the olive oil works great, the tea tree oil from this sampler definitely adds to the positive effect it has on my skin.
Matter is made up of tiny chemical building blocks called elements. Although dozens of elements exist, each one is distinct due to the protons it contains. Sometimes, an element can exist in more than one stable form if it has more or less neutrons. When this occurs, the elements are called isotopes. The element carbon exists in two stable isotopes, carbon-12 (6 protons and 6 neutrons) and carbon-13 (6 protons and 7 neutrons). Because essential oils are organic compounds, they are composed primarily of carbon atoms and will have a certain ratio of carbon-12 to carbon-13 isotopes. This ratio varies based on location around the world.

As we mentioned earlier, the FDA generally classifies essential oils as cosmetics, but they can also sometimes be considered drugs. In a quote direct from the US Food and Drug Administration website, “The law doesn’t require cosmetics to have FDA approval before they go on the market.” In addition, if a product claims to affect the health and function of the body, such as relieving anxiety, aiding digestion or calming sore muscles, the product must be approved by the FDA as a drug, which is a very long and costly process.


All of the reputable essential oil companies in this comparison are ones that have made a name for themselves in at least half of the States. I didn’t chart brands that are only known vaguely in a few States. All of the essential oil brands on this map are popular, well-established, and trustworthy. Now the question only is: will they work for you?
“The other important thing to understand is that any synthetic or improperly distilled component of the oil is very toxic! Because true essential oil constituents are so amazing at delivering nutrients to the cells (even pharma is using them for 100-4000X + increased absorption) that any synthetic, additive or improperly distilled oil components will get driven deep into the brain and cells by the real oil components making them very toxic.”
Feel free to reach out to me by email and I can give you my number…I have been with a company for a while now and they have great products but also a great comp plan compared to a lot of different companies out there. we just released our Ameo Oils line which is a certified clinical grade oil. Would love to share more information with you. Please reach out to me. One of the top distributors from one of the leading essential oils company just moved over to Ameo oils…The experience, the quality of the product, the comp plan, and the partnering of the moringa nutrition makes this an even more powerful solution to great health and living..

This is truly what I look for in lavender! I use lavender every single day, so having a great quality oil with value pricing is so important. I do wish shipping was done differently - I paid almost $9 for Shipping, and received my items in a USPS flat rate box that I know costs less than $6, so that was disappointing. The oils, however, never disappoint!


The use of essential oils during pregnancy is a controversial topic and one that is yet to be fully understood. The main concern during pregnancy appears to be the risk of essential oil constituents crossing over into the placenta. According to Tisserand and Balacs, crossing the placenta does not necessarily mean that there is a risk of toxicity to the fetus; this will depend on the toxicity and the plasma concentration of the compound.9 It is probable that essential oil metabolites cross the placenta due to the intimate (but not direct) contact between maternal and embryonic or fetal blood.10
Initially and up to this day, the necessity of testing is that most worldwide production of essential oils is for flavor and fragrance materials. The essential oil/fragrance industry has a long tradition of altering essential oils in the form of “standardization” and/or “extending” them. Purity is a problem with many big producers and distributors. Even the smaller essential oil producers and distributors are found to have quality problems too. Very few aromatherapy companies know what is in their oils because no one in the supply chain is analyzing their oils or in some cases outright doctoring their results. There are practical considerations; analysis is expensive, complex and takes years of experience.
I want to thank you for writing this piece. As a newbie to oils, I appreciate the time, effort, and education. While for some time, I knew there were things to be gained from EOs, the MLM companies pushing them just didn’t sit right with me. They were expensive and only get cheaper once you become a distributor. Sounds kind of like a pyramid scheme to me.
Chemical constituents of Boswellia sacra essential oil fractions were dependent on duration and temperature of hydrodistillation. For example, when essential oils collected from 0–2 h (Fraction I), 8–10 h (Fraction II), and 11–12 h (Fraction III) at 78°C were compared, longer distillation produced higher percentages of sesquiterpenes, between alpha-copaene and caryophyllene oxide (Table? 1). All three fractions were primarily composed of monoterpenes (82.77-90.67%), including alpha-thujene, beta-pinene, and myrcene. Among the monoterpenes, alpha-pinene was the major compound present in all essential oil fractions, ranging from 65.49% to 78.45%. As anticipated, the abundance of alpha-pinene decreased with longer and higher temperature distillation due to its highly volatile nature. Compounds such as borneol, dimethyl ether orcinol, allo-aromadendrene, gamma-cadinene, and caryophyllene oxide were only present in Fraction III essential oil…
The most important terms to look for regarding the way the plants are grown and harvested are: Certified Organic, Wild Harvested, or unofficially organic (sometimes called “unsprayed”). A reputable essential oil company will freely disclose all information about where and how their source plants are grown, and they’ll be proud of their organic choices.
Some essential oils qualify as GRAS flavoring agents for use in foods, beverages, and confectioneries according to strict Good Manufacturing Practice (GMP) and flavorist standards.[48] Pharmacopoeia standards for medicinal oils should be heeded. Some oils can be toxic to some domestic animals, cats in particular.[49] The internal use of essential oils can pose hazards to pregnant women, as some can be abortifacients in dose 0.5–10 mL, and thus should not be used during pregnancy.[citation needed]
