The products that ZEVA Essential Oils offers are 100% ISO certified essential oils derived from plant sources, and manufactured to contain active phytochemicals from plants without fillers or chemicals. ZEVA only uses oils certified by the Medicinal Oil Association, and we source our plants from quality suppliers throughout the world. However, because of the differences in organic certification from country to country, and even from one state to another in the U.S., it is not possible to acquire raw materials that are all certified organic. We do check our plant supplies for chemical residues in the form of solvents, herbicides, pesticides, and extenders so we can offer products that are as pure as possible, often exceeding the standards for certified organic products.
A pure, natural essential oil is an oil that is extracted from one species of plant from one specific geographical area.  The aroma profile for these oils will vary slightly from season to season and from geographical location to geographical location.  For example the lavender essential oil we sell at Moon Haven is a high altitude lavender grown and distilled in the mountains of France and we feel this is the best quality oil with the most appropriate and consistent scent profile of the plant Lavendula angustifolia.

Some oils may cause skin irritation or allergic reactions, which is why people should test their sensitivity to an oil on a small patch of skin, before they begin to use an oil more broadly, said Dr. Wolfgang Steflitsch, a chest physician at Otto Wagner Hospital in Vienna, and vice president of the Austrian Association of Aromatherapy and Aroma Care. He also said that certain citrus oils when applied to the skin can increase sun sensitivity, and that some substances in essential oils may be risky for pregnant women.

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!
Using a special type of Mass Spectroscopy, it is possible to determine which isotopes are present in an essential oil constituent and at what amounts. If sourced from the same location, every constituent in an essential oil should have the same ratio of isotopes. If a particular constituent has an isotopic profile different than that of the other constituents, then the quality control analyst will know that the oil contains an adulteration.
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.
I am most likely going to piss off some people with this post, but the information that I found was too good to keep to myself and keep you guys in the dark. As always, you should do your own research and question everything (even me!!). I ALMOST fell for the ploy. I got really excited because I felt like I was about to embark on a journey into the world of “top quality essential oils”. I thought that the lines I was being fed about these oils being “Certified Pure Therapeutic Grade” (or “CPTG”), “100% pure therapeutic grade”, and “therapeutic quality” meant that these essential oils HAD TO BE THE BEST. I was about to find out that all of these descriptions meant nothing in the eyes of the FDA and the aromatherapy world; they were just that, descriptions.
I have been using, ingesting and inhaling these oils for 10 years, and have had arthritis pain minimized, cholesterol levels lowered, my husband’s BP lowered in 20 minutes, been able to sleep without taking a drug, had excruciating reflux diminished and often eliminated in minutes. I don’t know what they can do for you…each person is different, you have to “play” with them until you find what works for your body chemistry. God created the plants for healing, not pharmaceutical companies. Sometimes there may be a need for a pharmaceutical for a limited time, but mostly…I’LL STICK WITH MY OILS and herbs thank you!
Hi Zach – yes true, if you make a syrup with honey (or other sugary substance) then the EOS will dissolve much better, which makes taking them safer. I think whether EOs are “safe” to take internally depends – on who, how, how much, how often, why, etc. So for me, there’s not a simple answer. Sometimes it’s fine, sometimes not. I will write more about this on my blog.

I really think i would’ve enjoyed reading your article and i think i may have gotten a lot out of it. However, trying to read around the block with “FOLLOW and icons for Facebook, Twitter etc.,” was infuriating!! I attempted to read your site on two different occasions and soon gave up both times. The second time i tried to get rid of the more than bothersome block by clicking on ea icon and choosing one of the actions to just get it out of my way, but no luck.

Thank you so much for all of your information that you share. It seems like when I google something about essential oils, I frequently end up on your site. I am new to essential oils and not sure what to expect. It seems like when I use them in lotion, roll-on, or even a eucalyptus steam the scent dissipates relatively quickly. I am not sure if I am not adding enough essential oils, if I am buying lower quality essential oils, or if I am expecting too much. For instance, a 8 oz batch of lotion (I used 30 drops total of essential oil)that I made last week no longer has a scent to it (at least to me). Any insight on this?

We have used Frontier/AuraCacia, MountainRose, RockyMountain, PlantTberaly and are happy with each of them. However, we’ve found Edens Gardens to work well for us. We love their blends, their sales/specials pricing and their customer service. We occasionally use the other brands (especially in a pinch) and sometimes place a order for AuraCacia through our Frontier Co-OP account.

Most essential oils are distilled and standardized (adulterated) for use in other industries, so those carefully sourcing and selling essential oils intended for aromatherapy and therapeutic applications understandably do want a way to convey the suitability, purity and quality of their oils for therapeutic uses. Soil conditions, seed quality, climate, altitude, growing conditions, harvesting, the care during distillation, bottling and storage can all play a part in the resulting quality of an essential oils. These are all factors that conscientious suppliers pay close attention to. Using these two-word terms seemed to be a concise way for suppliers to designate that their oils were suitable for use by those seeking oils for use in holistic aromatherapy.
Cosmetics and drugs are regulated very differently. Although a few researchers have obtained FDA approval to conduct research on essential oils used therapeutically (as drugs), most essential oils are not considered drugs by official agencies. Thus, they are available to anyone without a prescription and questions of quality are handled as for cosmetics, foods, and flavoring agents.
An essential oil that exhibits this quality will cause burning or skin pigmentation changes, such as tanning, on exposure to sun or similar light (ultraviolet rays). Reactions can range from a mild color change through to deep weeping burns. Do not use or recommend the use of photosensitizing essential oils prior to going into a sun tanning booth or the sun. Recommend that the client stay out of the sun or sun tanning booth for at least twenty-four hours after treatment if photosensitizing essential oils were applied to the skin. Certain drugs, such as tetracycline, increase the photosensitivity of the skin, thus increasing the harmful effects of photosensitizing essential oils under the necessary conditions. Table 3 lists some common essential oils considered to be photosensitizers.

Think about this for a moment – the aromatherapy industry is not the only user of essential oils. In fact, aromatherapy accounts for a very small percentage. The majority of essential oils produced end up in food flavouring, pharmaceutical, perfumery and personal care and these essential oils are usually modified to meet the standards required for each of these industries.
A few can be used on cats, but in general I’d go with the advice of Doing Research On Everything First. If my boys don’t like the smell of something (like my fingers after using an oil and before I can get to washing up…funny story there from when my boys were young) there is no way I’ll us it on them. But there’s also the fact that their systems do react differently.
Great article! I like the way everything is explained in detail. I love essential oils and use few kinds for aromatherapy, but the thing I always wanted to do is to include essential oils in my homemade cleaning solutions. In your article I found all the information and advices I needed, so now I already can use essential oils for cleaning too. Thank you for the hints!
There are some essential oils that can be ingested in very small amounts. For example peppermint oil capsules, which help IBS symptoms. I have used Young Living essential oils and they are of very high quality. Whatever people decide to do it is important to remember that essential oils do not disperse into water and therefore even the ones that are safe to ingest need to be taken with a dispersant drink, like milk or within special capsule. It is advisable to consult a professional in any case. All the best.
Most suppliers will not meet every one of the aforementioned criteria, but as you look at essential oil retail websites and contact suppliers, you will get a better feel for those suppliers with whom you feel comfortable and from whom you wish to purchase. Essential oil purity and therapeutic value is vital to essential oil safety and efficacy. There are quite a few excellent suppliers whose first priority is ensuring that the oils they provide are pure and of high quality.
Many essential oil producers and supplier now circumvent this checkered history of quality issues, wrong chemotypes and even adulteration by obtaining “organic certification”. This certification process runs up the cost of essential oils and as a result of the popular hype about the term “organic”, you are now paying 2-4 times over the price of conventionally produced oils.
DoTerra and Young Living are both Multi Level Marketing companies, making the oils more expensive. All pure essential oils are therapeutic. Young Living tried to copyright the term to set them apart. DoTerra is run by people who left Young Living. These two companies, as well as many others, get their oils from the same suppliers. They make their own blends, but there are some standard blends that are very similar from company to company. Ingesting oils is not necessary because they are so easily absorbed through the skin. I get my oils from a smaller company who uses the same suppliers and I get a lot more for my money!
I believe that the reason some (not necessarily all) E.O.’s are not ok to ingest is that some are extracted by means of chemicals as they are difficult to extract otherwise. You can find this out, or SHOULD be able to find this out via the source of your EO’s. Mountain Rose Herbs lists the extraction method and country of origin on each and every EO they sell. I like MRH as they are a local business here in Oregon and I like to support local business. They have also been wonderful about helping answer questions regarding their products, and are wonderful people as I have met them personally while picking up my orders. (NOT affiliated, just a huge fan!)
Yes, all our products are either steam distilled or cold pressed from premium natural botanical ingredients. Everything from our Select Series essential oils to the natural skin care oils in our Forever collection are sourced from our global network of diligently handpicked farmers, who produce our ingredients naturally and sustainably to our exacting standards. Different plants are native to different parts of the world, and because our oils are species-specific, we source them indigenously to ensure that their natural properties are exceptional.
I do have one BIG complaint about do-terra and it has nothing to do with the quality of their oils. They tell their young impressionable (and unlearned) people that their oils are so pure that they can be mixed with food, beverages, or put in capsules for anti-biotic use. Lets get two things straight here, “Antibiotic properties” are not the same as an “anti-biotic” and if you actually did ingest enough EO to actually do what they profess they can do, it would probably kill you as it would be so toxic.
Essential oils are generally extracted by distillation, often by using steam. Other processes include expression, solvent extraction, sfumatura, absolute oil extraction, resin tapping, wax embedding, and cold pressing. They are used in perfumes, cosmetics, soaps and other products, for flavoring food and drink, and for adding scents to incense and household cleaning products.
