The Ananda Apothecary operates business hours of Monday – Friday, 9am – 5pm MST. You can call 1-303-440-3766 for Customer Service or contact custserv@anandaapothecary.com. This brand also offers a newsletter, social media channels, and a neat “Aroma Science” section where you can learn a whole bunch of detailed essential oil information from their staff chemist (who is also their most active writer).
The only types of essential oils that should EVER be used are THERAPEUTIC GRADE essential oils. Otherwise, all the benefits of the essential oils are lost to the SYNTHETIC PETROCHEMICALS that are in MOST essential oils (even the ones you get at the health food store… I wont name brands)There are only two name brands that I know of that sell therapeutic grade essential oils.(there could be more) Those brands are Young Living ( Which I highly recommend) and Doterra. More expensive does mean better. Young Living does not sell any of its oils to any other company. There are only a handful of distilleries in the world that’s why most E.O’s are poor imitators. They are not all getting the oils from the same place. They are made in a lab instead.
What nutrients? What cells? Essential oils do not contain nutrients – they contain no vitamins, minerals, proteins, amino acids, carbohydrates, or any other type of nutrient. I have never seen any research that pertains to essential oils delivering nutrients to cells. Essential oil constituents have been used to enhance percutaneous absorption of pharmaceuticals, delivering them via the skin into the blood. But this pertains neither to nutrients nor cells. So the statement makes no sense.
One recent study of 300 patients found that those who breathed a mixture of ginger, spearmint, peppermint, and cardamom had much less nausea after surgery. Other research shows that lavender oil can lower levels of the stress hormone cortisol, and inhaling lemongrass aroma before a stressful event can prevent anxiety. Studies also show that tea tree and oregano oils can fight microbes, making them popular treatments for dandruff and toe fungus. Others can be used as an anti-inflammatory.

Hi I like this post but I’m still confused so 100% essential oil is not to be ingested? The reason I’m asking this is I am wanting to make raw chocolates with peppermint oil a lady and she is not qualified at all she just works at a organic shop she told me that it’s fine to use the oil in very small amounts! Like peppermint and that’s just it i use 100% eucalyptus oil for cleaning my bathroom and it states on the bottle POISON!
The truth is that essential oils are an end product of the plants metabolism and emitted by the plant not circulating within the plant like blood in the body (see magnified picture of oil glands on Roman chamomile leaf). Think about what some of the end products are from human metabolism and, if you want a more accurate analogy, well you get the idea. I realize it wouldn't be as marketable to use a tag line like "the excrement of the plant" but that would be more accurate than the "life's blood." But this does not mean that these end products, these secondary metabolites known as essential oils, are not extremely useful for the survival of the plant as well as being extremely beneficial to humans.
Great resource! It’s so important to understand the difference between essential oils and “real” — oils, seed oils, carrier oils, fixed oils — are there other names? I’m not sure. Both are wonderful, but they are so so different in structure and application. I’ve noticed a fair amount of misinformation going around where essential oils and carrier oils written about as the same thing or interchangeable. Your clear description is super valuable.
Ugh. This is a tough one. I think they’re extremely overpriced. For example, 1/2 oz of bergamot YLEO is $32.50 and 1/2 oz of certified organic bergamot EO at Mountain Rose Herbs is $14.50. I see that YLEOs are “kosher certified,” which really doesn’t mean much of anything (as all plants and vegetables are automatically kosher and nothing special happens or is avoided that “makes” them kosher).
#3. EO’s if diluted properly (not neat) and ONLY certain EO’s are safe for children. Peppermint is not safe until at least 6 years of age, some say older, as it can be a mucous membrane irritant. Eucalyptus has a 1,8-cineole content, its not recommended for children until the age of 10. Very important for childrens safety to do due diligence…these are just a few that come to my mind right of way and why they aren’t safe for children. I know there is plenty of other oils that are safe for children diffused. Once older, then ok for application, diluted in carrier oil. I was told 2-10 years old is when you can start adding more EO’s to your child(ren) library, as they age, you can add more. Of course I know this is hugely a hot topic. It depends on who you ask when you can introduce EO’s to babies and children. I know the MLM say put them neat on babies feet. No ones feet (bottom) will absorb EO’s as we have glands on the bottom of our feet, not pores to absorb the EO’s.
Bergamot Essential Oil has a fresh and delightful citrus aroma with strong citrus notes and a hint of the exotic, and has been made popular by Earl Grey Tea. This refreshing essential oil is suited for aromatherapy and induces a more relaxed and happy feeling, while reducing oiliness of the skin. Widely used in the perfume industry, it is also used in cleansers and toners.

The next oil brand is TRUessence, they do a lot of testing and have a very broad range of oils to choose from. The third company is Young Living and they do testing as well and also have a very wide range of oils. I also did the smell test with these and for me some were the same while others smelled like they had started to oxidize, making doTerra win out for me. However you could smell that there were not any other things in these oils like fillers and chemicals really easily.
Just to give anyone interested a typical example analysis, the picture below is of a certified organic lavender that I recently analyzed for a customer. As you can see the peak at 26.435 shows camphor present at 0.25%. Also, if you want peer reviewed literature references showing that camphor should indeed be in lavender, just login to my EO Chemical Reference database and you will see plenty of detailed reports, with journal citations, confirming exactly what I am talking about.
RC and Raven (YL Blends) are a few that I have used for myself and family for breathing issues. And Digize (also a Young Living Blend) is excellent for digestion, acid, and upset. Peppermint and Fennel are also options to look into. As far as best brand, you will have to do your research. I have been very happy with Young Living, but I know many will find the “best” from various sources to make up their essential oil cabinet. You will not want to use a vaporizer for your oils, I would suggest purchasing a diffuser which is designed to disperse your oils, over time essential oils will breakdown plastic tubing. A search on Amazon or Abundanthealth.com is a place to start looking at diffusers. You can also get a free one in premium kits sold by Young Living. Please feel free to contact me.
Having taught in universities and studied various healing arts modalities for over a decade, I unhesitatingly recommend Aromahead’s  Aromatherapy Certification Program to everyone – from beginner to daily user. The format is super user-friendly and content is beyond rich. The extensive case studies and amazing feedback set me on a great path of understanding how oils could be used to move the body into a deeper healing state. I now feel confident I’m moving into my aromatherapy practice in a mindful, safe, and ethical way.
Essential oils have long been used for enhancing the flavor of food and are commonly used internally for their therapeutic purposes. However, I must stress that anyone who recommends the oral use of essential oils for therapeutic purposes should be suitably qualified. This means that they should have suitable training in physiology, pharmacology and aromatherapy chemistry and should have a minimum level diploma qualification in aromatic medicine or a medical herbalism diploma.
I would highly recommend that anyone who is interested in essential oil toxicity to read this article regarding safety, including ingestion or neat application. I found it to be very helpful. It is a comprehensive article that was also published in an aromatherapy journal. Ron Guba, the author, is a well known Australian aromatherapist. http://www.agoraindex.org/Frag_Dem/toxicitymyths.html

Thank you all for your input and time. I too have been confused, frustrated, skeptical, and at times alarmed. What YL consultants don’t realize when they spout comments about micro and chemical biology, are the consequences that come with doing or not doing what they recommend. This is the grey area that is dangerous and the absolute reason and need for the FDA in the pharmaceutical industry. I am in the marketing industry, so I full well understand the MLM model or any other business model. I don’t blame them, for there is no difference between that and what Homeland does vs. Piggly Wiggly or Macy’s vs. JC Penney, or Walmart vs. Kmart… Thanks for helping me understand the real language and science involved.
The main reason I will not buy essential oils from any of the MLM companies is because they lead their customers to believe that when they say their product is “Certified Pure Therapeutic Grade”, that means something of value in the essential oil and aromatherapy world. There were three shocking things that I learned to lead me to steer clear of these

5mL Lavender Essential Oils; 5mL Sweet Orange Essential Oils; 5mL Tea Tree Essential Oils; 5mL Eucalyptus Essential Oils; 5mL Lemongrass Essential Oils; 5mL Peppermint Essential Oils; 5mL Bergamot Essential Oils; 5mL Frankincense Essential Oils; 5mL Lemon Essential Oils; 5mL Rosemary Essential Oils; 5mL Cinnamon Essential Oils; 5mL Ylang-Ylang Essential Oils

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.

This is a general summary for people who are using essential oils on a casual basis. 🙂 I didn’t want to muddy the waters here. However, I would gladly revise my statement if the oils were taken internally under the care of a naturopath or other professional. I just don’t think people should, willy nilly, run around taking them internally, due to their potency.
Only pesticide residues that are hydrophilic, thermostable, and volatile can be carried over into an essential oil during distillation. Few pesticides possess these characteristics, so pesticide levels found in distilled oils are typically insignificant. In one large database, out of 73,541 analytical results on distilled essential oils, only 0.55% had positive results for pesticide detection.
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.
Essential oils were once a small market product available mainly through trained aromatherapists and medicine men and women. With the massive production scale we are now seeing in oils, many are being grown as mono-crops requiring heavy amounts of pesticides, mass harvesting and in some cases irresponsible harvesting. This can both endanger plant species and hike the prices.
Most avid essential oil aficionados understand that there is no independent standard for “Therapeutic Grade” that is universally recognized. Let’s be honest, it’s hard to even pin down exactly what does “therapeutic” entail in the first place, at least in any quantifiable aspect. And while you may not like the promotion of Therapeutic Grade by various companies, it’s not really correct to say that “thereis no such thing as Therapeutic Grade” because companies do have the freedom to make up any grading system they want. It’s just important to be aware that these grading standard are largely just marketing ploys by most companies. I think a better response to those promoting such an idea would be to say"while many companies promote their own therapeutic grade standard, one should be aware that there is no universally accepted independent body that certifies essential oils as therapeutic grade." That is a fair statement that is factually correct and nobody can refute. Using this language will not cause dialog to shut down between those on the MLM side and those on the more traditional side of aromatherapy.
Resins and complex combinations of terpenes are released by some plants and trees, such as evergreens, to act as antimicrobial, antifungal, and antibacterial agents against a wide range of organisms that may threaten the survival of the plants. Compounds such as sesquiterpene lactones found in plants such as feverfew, yarrow, and blessed thistle, have been found to play a strong antimicrobial role as well as a protective role from herbivores.

"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.

Hello, I've only been using essential oils for the last year and I've been doing a lot of research trying to buy from the safest place because I know the Sham on the grades and how therapeutic is just a term. My question to you is do you know anything about (Bulk Apothecary) brand? I was buying from them for almost a year and then it was recently I asked them for three of their C of A's they sent them to me, but he gave me a problem when I told him one of the brands they sell of henna was bad. I don't know what I'm supposed to look for on this certificate which I'm trying to research to find out. One of the essential oils it says that complies all the way down the other two it says it complies and then it gives it some type of percentage. I guess I would just like to know if you think that they are real or if you've heard of them they do offer all of the information like you say in your blog to look for, such as the bontanical name how it's been distilled and even the history. I know the smell on every single essential oil we've gotten from them has been very potent. Thank you and anything would help even linking me to the right direction.
Frankincense can be used for depression, inflammation, immunity, and to increase spiritual awareness.Today, scientists, physicians and researchers are beginning to return to the use of essential oils as a way to naturally and holistically heal our bodies. Frankincense actually has a history of medicinal use and could be quite helpful in your medicine cabinet.

One of the keys to producing the highest quality essential oils is to have the highest quality growing conditions for the plants prior to extraction. For that reason, ZEVA focuses on sourcing our plants from indigenous regions where the growing conditions are ideal for the plants, rather than trying to force them to grow in a non-native, less hospitable environment. Our team works with suppliers from around the world to find the highest quality ingredients to go into every essential oil we produce.

Thank you so much for putting this information together. I really like this site. I am excited to follow it and learn more. I am in a company that does adaptogens and recently started seeing and learning that some of the EO’s are also adaptogens. I started using some and got some terrific results. Lots of stress that has been relieved. Then I had started to lose weight and after about 46 lbs found I could use grapefruit and frankincense and it was helping with taking away the wrinkles a saggy parts. Maybe you could cover this in some of your articles..
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.
A few preliminary studies have suggested that peppermint oil may help with irritable bowel syndrome. Although the oil is touted for working as a decongestant and reliving headaches and muscle pain, "there is no clear-cut evidence to support the use of peppermint oil for other health conditions," the NIH says on its website. Capsules of peppermint oil may cause heartburn.
Hi Linda. I don’t know about restoring hearing but I have been using oils with good results for tinnitus and hearing that sounds like I’m in a tunnel. It seems my right ear is trying to loose some of it’s high pitch hearing. Whenever I have this happen I use a combo of oils. Helichrysum is one of them. I rub it around the inside of my ear (never drop oils into the canal). Then I apply Frankinsence, Basil, Rosemary, and Melaleuca on the bones in front and back of the ear and down the neck where the eustachian tube is. Sometimes I’ll put a drop on a very small cotten ball and place it in my ear while I sleep. I’m using this now as preventive as my hearing has returned and the tinnitus has stopped. I only do this 2-4 times a month now. But at the first signs of anything happening in my ear I resume doing it twice a day. I’m in my fifties now so I can’t afford to take chances.
I went to an Essential oils party last week (YL). They had everyone put a little bit of water in a glass, then a drop of oil (I used grapefruit) and then fill the rest with water and drink. I wondered if it was safe since I’m 27 weeks pregnant, but since the leader made no mention of caution (and one of them was also pregnant) I assumed it was ok. Now after doing research, I’m horrified and so worried I have harmed my baby! What are your thoughts? Since grapefruit is on the “safe” list and I only used one drop (and don’t plan to ever again!) do you think it’s ok? I’m completely panicking and so mad at myself for making an assumption.
Look for oils that are organic as a first choice. Any pollutants on the plants can be more concentrated in the essential oil. This is especially important for citrus essential oils, as they are traditionally heavily sprayed with pesticides. The term “organic” means different things in different countries, but it is one more possible indicator of quality. Some retailers also carry oils that are “unsprayed,” where the farms are not certified as organic, but they do not spray their crops, and many high quality oils are also wildcrafted.

Yes, of the 3 brands I am most comfortable using for therapeutic purposes the first is doTerra. Its testing exceeds everything else I’ve come across protecting against not just fillers and chemical extraction, but also against oxidation for potency levels. When air hits the oils for a period of time they oxidize slowly and if that happens they may be less quick and effective than if they had not had that time to oxidize. No other company tests the same number of times for this level of potency. I also love that the testing is done by a third party rather than in house testing.
I have purchased from Edens Garden a number of times. I really enjoy your products. Before making a decision, I sent a number of inquiries to them about their oils. They are very good a sending back information to help you make your decision. From everything I have learned: They are 100% pure. They have cut out the middle man so they can lower the price and they have quick service. I have purchased the same thing from a couple different places and find I like the Edens Garden best. (I can afford these, not some of the other brands, too) I personally haven’t found any discrepancies.
Olbas Oil may cause problems even when not applied directly to the eyes. The mother of a 4-month-old boy placed several drops of Olbas Oil in his right nostril in an attempt to help his respiratory infection, not realizing that the product warns against use in infants. The child immediately showed signs of respiratory distress, and was taken to the emergency room. Two hours after admission his eyes became inflamed, and examination revealed bilateral superficial corneal scarring. He also had conjunctivitis, and could not open his eyes. They were flushed with saline over four days, and he recovered with no residual scarring (Wyllie and Alexander 1994).
Thank you so much for this excellent distillation! I’m just beginning to use EO’s, and have had such excellent results that I am encouraged to try more — thank you for helping me find reputable companies to purchase from. The pricing comparison was especially helpful. My only issue so far is with Aura Cacia — the lids are so hard to get off the bottles — my 71 year old hands just can’t exert that much pressure any more — I emailed the company thru their website, and was sent alternative bottle caps, that didn’t even fit the bottles. Alas, not buying from them any more, which is unfortunate, since they are readily available in local stores. However, online ordering is easy and quick. Thank you once again!

Don't many of us have that "crazy uncle" or other relative who is constantly spreading emails with headlines like "New legislation requires a microchip in the brain of every newborn by 2025" or similar craziness? Then we do a simple google search and in 30 seconds send them a link to snopes or some other myth debunking site that shows clearly why its not true. These kinds of emails are so annoying to the thinking person I wish that these people could see how they are coming off to anyone with half a brain. It's so unnecessary and they could have saved themselves from looking like a tool by just by spending a little effort to check things out.


Many EO users don’t know this because Ameo has only been around for a little over a year, but clinical-grade is the highest EO grade available in the U.S. They are extensively tested to make sure the quality is as high as those oils used in clinical testing or even higher potency. I’ve used most other brands, and know what I know now I would absolutely never use another brand internally unless they were certified organic because of the risk of getting synthetic ingredients and toxins. However, using just ‘organic’ oils does NOT ensure that you have the highest potency/efficacy which you can be sure of when you use Ameo. If you watch the videos on the website you’ll understand more about it. There are videos of the oils penetrating human cells posted for every single batch of oils from Ameo.
I am trying to write an essay for a public health post grad course, the role of the public health worker.. I won’t bore you with the details… I’m trying to tentatively suggest that education is a major role….non antibiotic therapies for infectious disease, for example tea tree in the treatment of staphlococcal…. can you suggest any reading/authors/doctors I can explore?
Love this article and your references!! Much appreciated from someone who is new to the aromatherapy world and wanting more information. I hope to understand how to use EO for my family. I signed up with DoTERRA to get training and so far a month in haven’t received much training. So now I look for articles like this…wish I had a friend who was certified in aromatherapy so I can help my whole family understand what to use and how to use it with different problems. Reading articles helps but I definitely get overwhelmed with all the information…anyways love this article! Thanks!!

I used grated carrots covered with Saran wrap for 24 hours followed by grated garlic covered with a large bandaids.( both as poltice) I used the garlic for 48 hours. After that I just applied bandaids as there was a large hole in my hand. Within a week the area that had been covered with carrot/garlic turned black. I lifted the corner and the whole piece came off. Beautiful pink skin was there! The carrots took the pain away instantly and the garlic kept any infection at bay.
First let me say if you are using terms like "first pressing" then you've really got some catching up to do on your essential oil education. Most all essential oils are steam distilled, in fact this is inherent to the very definition of an essential oil. The only oils that are considered to fall under the definition of the term "essential oil" and are not produced by steam distillation are the citrus oils, which are cold pressed from the citrus peel (and if its done properly there would not be any oil left in the peel for a second pressing LOL). So when one refers to the so called "first pressed" essential oils they does not even portray an accurate method of production of almost every essential oil out there, since almost every oil is produced by distillation, not by pressing. Please avoid this "pressing" terminology unless you want to just sound like a complete novice to the field. When the pressed method is applicable, in the industry we use the terms COLD PRESSED or EXPRESSED to describe the production of citrus oils (some citrus are also distilled but that’s another issue). So this brings us to the whole issue of the claimed "multiple distillations" of the same plant material. Consider this quote from a popular blog:
Hi, I am new in this EO thing, and your info was very helpfull, thank you, I started to get some of my oils from swiss just, don’t know if you have heard about them, until now I think they are good, some other oils from Do Terra and Native American NUtrionals, don’t know how good in quality they are, just started to experiment, so far I think my favorites are swiss just and N.A.N., hope I can get to learn and know them better. Any suggestion, on how to use palmarosa EO? Is it good for wrinkles on the face? If not which one do you recommend? Thank you. Mother of one.
Supercritical carbon dioxide is used as a solvent in supercritical fluid extraction. This method can avoid petrochemical residues in the product and the loss of some "top notes" when steam distillation is used. It does not yield an absolute directly. The supercritical carbon dioxide will extract both the waxes and the essential oils that make up the concrete. Subsequent processing with liquid carbon dioxide, achieved in the same extractor by merely lowering the extraction temperature, will separate the waxes from the essential oils. This lower temperature process prevents the decomposition and denaturing of compounds. When the extraction is complete, the pressure is reduced to ambient and the carbon dioxide reverts to a gas, leaving no residue.
