Essential oil purity and quality is vital to essential oil therapy and should be the highest priority in using essential oils in treatment. Adulterated and low quality essential oils are an ever-increasing problem as demand outpaces supply. Using bad oils on a client, at best, results in a lower than expected curative effect, but worse, they may actually have a negative or toxic reaction in both the practitioner and client. Using pure and high quality oils are good for your client, business, and reduces your exposure to liability.
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.
Amy, organic crops may be contaminated by pesticides from nearby farms, but 100% organic is not impossible, and contamination is the exception. Distillation probably does reduce the proportion of a biocide, but most of them do carry over and will be present in the corresponding essential oil, usually in the 1-10 ppm range. You will get very much more biocide into your body by eating non-organic foods than you ever could from a few drops of essential oil containing 2 ppm of a biocide. Getting back to your question, most certified organic essential oils are biocide-free, but some may contain biocides, and the only way to be sure is to analyze the oils. The presence of a biocide would be regarded as a contaminant, not an adulterant. (An adulterant is a substance intentionally added for profit reasons.) The bottom line is that a certified organic oil is, on average, very much lower in biocide contamination than one that is not certified. Having said that, some oils are biocide-free but are not certified. You might find this website helpful:
If you are using Firefox or Google Chrome as a browser there is an app/add-on called “adblocker plus”. Download and install it. When you see floating icons like that and they bother you, right-click over them and scroll down to “block element” or “use adblock” and click OK/Submit/Add. This will remove the floating script/image and allow for better viewing.
To give you an example the perfume industry requires a standardised scent profile for most of the oils that it uses so that the perfume that they manufacture has a reliable scent.  So  the oils supplied to the perfume industry are usually standardised accordingly. Lavender 40/42 is  where two of the main constituents in lavender oil, linalool and linalyl acetate, are added to the oil to make up 40/42% of the oil.

You can ingest some essential oils and there are good reasons to do so. If they’re awesome outside the body, perhaps they would be inside too? They’re antifungal, antiviral, antibacterial, etc. Of course you need to be careful and use good judgement. Too much of anything can be bad for you. Candy companies & chocolatiers have been doing it for ages and there’s no reason you can’t too. I’m off to make some lavender blueberry scones. Good morning!
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.

One of my biggest frustrations of late has been a MLM company, I won’t name names and start a whole “thing”, but they state that they have a patent on “certified therapeutic grade”. In actuality, if you research the information, the only thing that is patented, is the logo that states “certified therapeutic grade”. It has nothing to do with the actual product, just the advertising.
Standardized oils are not always clearly marked as such. Additionally, some essential oils are tampered with, also known as adulterated, in order to give the illusion that the oil is of an higher quality than it is, or to extend more costly oils in order to make more money on the sale of the oil. For example, the pricey Japanese citrus Yuzu Essential Oil resembles a combination of grapefruit and mandarin essential oils. Some sellers may be tempted to blend grapefruit and mandarin essential oils together and market the blend as the more expensive Yuzu Essential Oil. Patchouli Essential Oil is sometimes extended with the addition of less costly balsams or cedarwood. Lavender Essential Oil is sometimes adulterated by the addition of more linalyl acetate.
I 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.
This is something that should be readily available. For example, the company Aromatics International lists their oil data right on the respective product pages. Most often, you won't often find this posted on websites, but upon request, you should be able to receive it. According to Aromatics, "Gas Chromatography (GC) is a method of separating the volatile compounds in essential oils into individual components and produces a linear graph that charts these components. Mass Spectrometry (MS) identifies each of these components and their percentages. This process is used to identify any adulteration of the essential oil tested. The precise breakdown of the chemical components in individual oils given to us by GC/MS reports are important as the therapeutic benefits and safety issues of essential oils are, in large part, determined by their chemical makeup."

Enormous amounts of plants are needed to produce essential oil. In fact, on the extreme end, it takes 4000 pounds of Bulgarian roses to produce 1 pound of essential oil. Other plants like lavender only take 100 pounds of plant material to produce a pound of essential oil. Still, can you imagine how concentrated essential oils must be, in light of how many plants are used to produce them?
The notion of using essential oils as a replacement for standard medical therapy is not new. Today’s essential oils are yesterday’s herbal remedies. They’re your grandmother’s swamp root, your great-grandmother’s liver pills and your great-great-grandmother’s snake oil (hey, at least we made it back to oil). And as in those days, somebody’s getting rich selling their wares. Why? Because there will always be folks who claim they work and others who buy into the claim looking for a quick fix. My question for believers in the crowd: how do you know the remedy really did the job? Runny noses get better. Coughs and bellyaches go away. Rashes clear up, skin heals and behavior fluctuates.
Essential oils are of great importance when it comes to hair. Essential oils like lavender oil, rosemary oil, cedar wood oil, thyme oil, peppermint oil and the likes are of great importance. Lavender essential oil has properties which provide deep relaxation. This oil, as well as thyme and peppermint essential oils, prevent hair loss and promote hair growth when massaged into the scalp.
Hi, danelle. I have a daughter name danielle, but anyway, I’m marilyn. I love your post. I am a EO user for 3 yrs now. Learning more and more about this world of EO’s and loving them. I too, suffer now with degenerative problems and excruciating pain at time. My question, did u have a daily routine and what oils were u using. I’m trying to get away from conventional meds unless extreme situations. EO’s are absolutely amazing! Thank you.
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.
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!

Contrary to what several essential oil companies recommend, the oils generally should not be swallowed, Power says. The body absorbs more this way, boosting the chance that they will interact with medications or cause an allergic or toxic reaction. Even continued exposure to small amounts (a few drops a day in a water bottle) can lead to fatigue and headaches. Taking in larger amounts of certain oils -- like tea tree oil, wintergreen, and camphor -- can lead to throat swelling, a racing heart, vomiting, and even seizures, says the Tennessee Poison Center, which saw the number of toxic essential oil exposures double from 2011 to 2015.

“d?TERRA’s CPTG Certified Pure Therapeutic Grade® quality standard is more rigorous, yet very different in nature and function than the ISO monographs for aromatic extracts. This statement, however, should not be interpreted that AFNOR or the ISO has a standard for “therapeutic grade” essential oils or that any essential oil product has AFNOR or ISO certification or approval. They do not certify brands nor do they grade essential oils as therapeutic, grade-A, premium, etc. The ISO monographs for essential oils are not comparable nor serve the same quality control function as the d?TERRA CPTG standard.”
Taken by mouth, many essential oils can be dangerous in high concentrations. Typical effects begin with a burning feeling, followed by salivation. In the stomach, the effect is carminative, relaxing the gastric sphincter and encouraging eructation (belching). Further down the gut, the effect typically is antispasmodic.[14] Typical ingredients for such applications include eucalyptus oils, menthol, capsaicin, anise, and camphor.[citation needed]
