The truth is that as long as you are mixing each oil in the EXACT same percentage in each trial, the order of blending each component would almost never reveal a significant effect. When people do claim to notice differences in blends based on order of component addition, its typically because they do not have the ability to conduct the experiment with quantitative accuracy. For example, it would not be a scientific experiment to do various blends using drops of essential oil from orifice reducer bottles or even by counting drops from a pipette. The reason being that drops are often drastically inconsistent, even when using the same oil with the same dropper. The only way to accurately put together the blends is to use a digital scale, I recommend one that can weigh out to at least 0.001 gram. If all the components are added to blend in the exactly the same amount each time the blend is made and the components mixed thoroughly then the odor and chemistry should be identical each time, regardless of order they were added to the blend.
* It’s important to note that essential oils are incredibly powerful and need to be used very very wisely. You need to know what can or can’t be put on skin directly, and only use internally under the care of someone who really knows what they are doing.  I’ve burnt myself using too many drops of certain oils in the bath and have been silly in the past putting some oils on my skin undiluted – ouch!
When washing clothes I use regular soap (haven’t looked into home made yet), and then put about 2 tablespoons of Epsom salt scented with a few drops of essential oils into the bottom of the washer before adding clothes. Then instead of using fabric softner I fill the dispenser with regular white vinegar. It keeps the washer from getting that funky smell and my clothes come out way softer. At first I was worried you would be able to smell the vinegar, but I have been doing this for 6 months now and you really can’t smell it! The Epsom salt doesn’t really have to have essential oil in it, the scent seems to rinse out in the wash but I like the little burst of scent you get when you dump it in, and use fairly cheap oils like citrus for it. If you want your clothes to actually smell of the oils you can get some wool dryer balls and add an oil of your choice before drying.

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

Wow, there’s quite the controversy regarding the ingesting of oils and quality of oils. You know what would be amazing… a post that helps newbies in the EO world to know about the various EO distributors aside from YL and doTerra. I feel like the market is saturated with their jargon and I’d like to know about other suppliers so that I can make my own informed decision. Would love it if you could share any other links to companies, or resources, you might now of so I can further educate myself. TIA.

I decided that it was time to upgrade my essential oils, and signed up to sell doTERRA essential oils. I didn't really plan on selling essential oils to many people, as I was just looking to get the 25% off discount that you get for being an “Independent Product Consultant” or “IPC” as they call them. When the introductory 3-pack of essential oils (lavender, peppermint, and lemon) came in, I was really excited to smell the difference! The first one that I opened was the peppermint essential oil and I was shocked at what a candy-like smell it had. It smelled so deliciously sweet that I was blown away because all of the other peppermint essential oils that I owned smelled of  the herbaceous earthy peppermint that you find in the garden; doTERRA's peppermint essential oils smelled like the finest peppermint candy I had ever smelled. I assumed, that since these essential oils are 100% pure and “Certified Pure Therapeutic Grade”, that the higher end brands had better smelling peppermint. This excited me, I could smell a difference! I had been afraid that I wouldn't be able to smell the difference. The funny thing is, I thought that because the doTERRA essential oils smelled better AND are “Certified Pure Therapeutic Grade”, that they were better…but I was only listening to the MARKETING.
Refreshing and radiant, we carry several varieties of Lemon Essential Oil. Two of our most popular sellers are the regular Lemon and the Lemon 5 Fold, for their long-lasting, pleasant fragrance. The aroma is intensely citrusy and fresh, with wonderful zesty top notes. The Lemon 5 Fold is highly concentrated which makes it especially desirable for cosmetics, as well as soap and candle manufacturing.
Essential oils aren’t really oils in the true sense of the word. They are complex mixtures of aromatic compounds extracted from plant material. They have distinct odors, poor solubility in water (a trait they share with true oils), and are extracted from plants by distillation and cold pressing. Common examples include lavender, peppermint, tea tree and eucalyptus, but you’ll find hundreds more.
USE ESSENTIAL OILS TO HELP YOUR MOOD. Lavender, peppermint, grapefruit, chamomile, lemon, ylang-ylang all help produce happy, joyous moods. Clary sage helps with PMS (although there have been reports that overuse of clary sage can lead to intoxication). Rosemary increases focus and concentration. Don’t forget the mood benefits of essential oils. Here’s an information packed aromatherapy reference chart to refer to.

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.
Potential essential oil buyers should independently check out the marketing information provided by essential oil traders - do not be put off asking for any extra information or reassurances that you are legally entitled to if the situation is not absolutely clear cut. The professional aromatherapist has a duty to be able to provide all relevant safety information relevant to to their clients’ treatment(s) and therefore it is part of ‘due diligence’ to ask questions, require any stipulated proofs, request an MSDS, ask for compositional data & certificate of origin of the batch of oil purchased and have their eyes wide open to marketing ploys & scams of all types - including providing GC’MS print-outs and other information which relate to other batches of oils entirely, and, of course, describing essential oils as ‘therapeutic grade’.
I’m not sure what you mean when you say “gras” but I wouldn’t recommend using just any essential oil, especially when you are putting it in your mouth. American standards only require 2% essential oils in a bottle that is labeled “100% Pure”. It’s really unfortunate we have such lax standards. Be Young uses the International standards for essential oil purity (E.O.B.B.D.)
I just want to add a note here on behalf of those companies like NOW and Aura Cacia and all the others from the health food store I’ve tried. They may have all good intentions. They may or may not be testing their oils, anyone can give a test. The mass spectrometry test will pass with a very high amounts of filler oils and chemicals from extraction in it. These issues may not necessarily be from the owners of companies that get oils out there, it may be from the farmers selling the oils and trying to get an extra buck or from somewhere else in the line of business people it goes through before it gets to our shelves. Our world is very focused on money so who knows where the fault really falls. If you’re wondering what brand you should use, I would recommend the three above… doTerra, TRUessence, Young Living… however, I think its better for people to decide for themselves, so maybe do your own smell test. I’ve also been told that if an oil says “not for internal consumption” then there’s a pretty high chance that it is not as pure as it should be to be safe (at least if its is on the FDA’s GRAS list). I know this is long, but hey you asked right? And anyhow, education brings true freedom.
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 was just barely speaking with a girl who is a certified aromatherapist and she said that people need to be very careful with wintergreen because it is such a strong blood thinner. I think this may be part of why it specifically is deemed unsafe for internal use (whether its pure or not). When it says wintergreen oil on ingredients lists I’m willing to bet it is a synthetically created oil or other form of it rather than the essential oil because of its therapeutic properties.
” Essential oils are wholly natural and cannot be patented; which means that you’ll never see an essential oil in a pharmaceutical drug. As such, you can expect that the vast majority of mainstream healthcare practitioners will never recommend essential oils as therapeutic alternatives to drugs. More importantly, because essential oils cannot be patented, drug companies will not waste money studying them. This limits our scientific knowledge of essential oils GREATLY, and the majority of what we know about them are things that have been passed down through thousands of years of personal use and experimentation.” So how can any claim to be “therapeutic”….? WE all know they work but….

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.
Essential oils aren’t created with carrier oils – they’re extracted using a variety of methods. The most common are cold-pressing and steam distillation. Most citrus oils are cold-pressed (the name is pretty self-explanatory: they’re pressed), but almost all other essential oils are steam-distilled: the plant matter is placed above steaming hot water, the steam takes essential oil from the plant, and travels through a condenser. After condensing, you’re left with water and a tiiiiiny bit of essential oil floating on top.

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.

Dr. William Thompson (senior CDC scientist), who is  mentioned above as co-author of this study, blew the whistle and admitted that he was pressured to omit statistically significant data, and that there is a connection between this vaccine and autism. He released this statement in an official capacity, as explained by the Congressman in the video below. This story was an has been completely ignored by mainstream media.
More than 65,000 work-related eye injuries and illnesses are reported annually in the USA, a “significant percentage” of these being ocular chemical burns. They require rapid treatment, and severe burns have a poor prognosis. The standard treatment is copious irrigation with saline solution for 1-2 hours. Contact lenses should not be removed initially (Peate 2007). With essential oils, fatty oil has been suggested as an appropriate first aid treatment though the advantage of saline is that the eyes can be continually flushed, and this is less easy with fatty oil.

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.
