It’s been a few months since you posted, and I hope you are feeling better! My youngest is now 10 and I am JUST now, as I am learning about my peri-menopausal experience, getting an understanding on my postpartum experience. I struggled for months with each kid and now I am pretty sure the base-line physical issue was hormonal imbalance. I have been taking a product from Young Living called Progessence Plus, and it has been a life-saver– I wish I had it when I was postpartum. Look it up, theres a PDF by Dr. Dan Purser talking about the product that answers a lot of questions and helped me a lot when I was researching. There are other oils from YL that help a lot with hormonal issues, Dragon Time, Schlaressence, Lady Schlerol. (Use my distributer #1112524 🙂 if you want to buy from YL)
General safety guidelines include: avoid application of known dermal irritant essential oils on any inflammatory or allergic skin condition; avoid undiluted application; avoid application on open or damaged skin; and dilute known dermal irritants with appropriate vegetable oil or other carrier. If you suspect a client has sensitive skin, perform a skin patch test. Table 1 lists some common essential oils considered to be dermal irritants.

Thank you for this wonderful information! I have been inundated with the numerous brands of essential oils on the market. I have read reviews, but by far your information has helped me the most. I have been using oils for my Chronic pain & Neurosarcoidosis, always worried if the oils we’re harvested safely. This information will now allow me to make better decisions on my therapeutic treatment in the future! Thank you for your lengthy research!

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.


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.
Previously mentioned in Module 3, the chemical profile of an essential oil is a crucial determinant of the overall quality. Certified Pure Therapeutic Grade® essential oils should always have certain ratios of the same core constituents, as these major constituents are largely what determine how the oil will interact in the body. Because essential oils are pure botanical extracts, the ratio of constituents will fluctuate slightly depending on the geographic location, weather conditions, soil conditions, insect presence, precipitation, temperature, distillation conditions, etc. Quality control tests should be used to monitor the chemical profile of each batch of oil and determine if it fits within the proper ranges that will result in beneficial health effects.
“The first data set used by DeStefano et.al represents a huge lost opportunity to understand any role between the timing of the first MMR vaccine and autism. The re-analysis presented here elucidates effects that should at least merit further investigation. Specifically, increased risks of earlier vaccination are observed for African-American males and among cases of autism without MR. Both phenomena deserve additional study that could yield important clues regarding the current enormous increase in autism.”
I would love to know more about essential oils to avoid concerning environmental impact. Because it takes so much plant material to create a small amount of extract, it would be handy to have a list of oils that come from plants that are endangered or being irresponsibly harvested. I’m having trouble finding a comprehensive list online. Any suggestions?
I’m familiar with EO at one time I used YL the only problem with that is they were to expensive in my opinion. So I quit for awhile. I deal on a daily basis with fibromylgia,osteoarthritis and anxiety. Due to all this my doctor took me off of a sleeping pill said I was sleeping to much in the day plus I went to the library for a free class about sleeping patterns and I was told to get off the OTC sleeping meds. Wow want to talk about a withdraw plus the lack of sleep I was getting. I was like an owl still sleeping in the day up at night. I had to do something. My sister told me about piping rock that’s where she’d been getting her essential oils. So I got my Lavender and Bergamont and at reasonable prices.Their great I sleep well now.
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.
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’.
As far as I can tell, ‘wintergreen oil’ is not listed anywhere by the FDA. Methyl salicylate IS permitted by the FDA as an indirect food additive, when is is a constituent of an adhesive. It is not on their ‘regular’ indirect food additive list – only the one that applies to adhesives. But I can’t see it on any negative list, and I can’t see a maximum permitted amount.
In short: DO NOT TAKE ESSENTIAL OILS INTERNALLY unless they have been prescribed to you individually by a qualified and clinically-trained medical professional or Clinical Registered Aromatherapist. When working with essential oils you are ultimately playing with chemistry; if you do not know the specific chemistry of the specific oils, and what that specific collection of chemical constituents in that oil can do to your body, then avoid internal administration and stick with the aromatic processes.
Then we purchased bottles of Lavender (Lavandula angustifolia), and Lemon (Citrus limon) from each of the seven companies we selected to perform our in-house testing. We gathered a group of four people from our office and administered a formal blind smell test to evaluate which oils smelled the best and which smelled the worst out of the selections.
As oils are commonly used for inhalation and in combination with carrier oils for transdermal absorption, meaning rubbed into the skin in diluted forms, they are bypassing many of the body's natural protective mechanisms and detoxification channels. Substances rubbed directly into the skin can go straight into the bloodstream and begin circulating - the good and the bad. Ideally, we only want the good entering our bodies in this method. Let our beauty care become our medicine.
Janice – no, it’s not at all junk science, and this is what ISO standards are all about – the maximum and minimum ranges of key constituents. This does of course vary with different chemotypes, as well as different species, and it can also vary with geographical origin. So there is an ISO standard for peppermint oil from the USA, and a different one for the rest of the world. (this is not elitism – ISO standards are not US-based.)
Ingesting essential oils daily will damage your microbiome, in my opinion. Is there a study to prove this? No, as the doTERRA advocates will point out. Is there one showing that it does not. Ummm no. But there is research showing how powerful these oils are at killing bacteria. And we know that they will make contact with the microbiome. It isn’t rocket science, you ingest a powerful antibacterial and you will kill your bacteria.
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!!

To test if you’re sensitive to an essential oil (which is probably best to do before using it in a skincare preparation): Combine one drop of essential oil with 1/2 tsp carrier oil (like olive, jojoba, or sweet almond). Rub this on the inside, upper portion of your arm and wait a few hours. If no redness or itching develops, you’re most likely not sensitive to that essential oil.

A 2009 report from an ophthalmologist in Bristol UK, describes partial loss of corneal tissue (ie erosion) when a 73-year-old man dripped Olbas Oil into his left eye (he had no right eye) because he thought he was using eye drops (see picture above). He was “considerably incapacitated”, but recovered after a week of treatment with “topical antibiotics and lubricants”. On checking, the author found that just his hospital, in the previous 18 months, had seen 12 patients who had mistakenly dripped Olbas Oil into one eye. He describes the result as a chemical burn, though he found that Olbas Oil in tears was pH neutral (most chemical burns are caused by substances that are strongly acid or alkaline). All “Olbas Oil patients” recovered fully within one week following intensive treatment (Adams et al 2009).
Today, the processors (distillers) of essential oils carefully blend proprietary mixtures of L. angustifolia subspecies and cultivars to produce a combination of true lavender oils that have a more consistent aroma, rather than providing only the low-camphor Reya and Munstead subspecies as specialized perfume ingredients. These other lavender essential oils are as true and pure as the two cultivars used by perfumers, but with four cultivars they provide a wider palette of scent and a more diverse scope of practical application due to their wider range of natural constituents.
Typical research studies involve testing two groups-one group gets an experimental substance and another group gets a placebo substance (this group is referred to as the "control" group). When using aromatic substances, it is very difficult to conduct a blinded study. Some researchers have used masks or other barriers to blind participants. Other researchers have used alternate scents assumed to have no therapeutic properties as controls. These approaches are problematic, however, because people associate smells with past experiences. Thus, it is difficult to account for individual variation in how essential oils affect people.

Mass Spectrometry is used together with Gas Chromatography to further determine the composition of an essential oil. In Mass Spectrometry, the constituents previously separated by GC are ionized and sent through a series of magnetic fields. Using molecular weight and charge, the amount of each constituent can be identified, providing additional insights into the potency of the essential oil.

This kind of statement has always left me scratching my head. Sometimes it is also stated as “….EOs are the most OXYGENATED substances on earth.” Whether its meant to be OXYGENATING or OXYGENATED the statement is just plain wrong. Yes essential oils contain oxygen but that doesn’t equate to be “oxygenating” or the “most oxygenated.” Those of you taking my Chemistry of Essential Oils course already know that, 99+% of the time, when we are talking about essential oil molecules, we are concerned only with 3 elements of the periodic table: Carbon, Hydrogen and Oxygen. The molecules in essential oils are mainly mono and sesquiterpenes and their oxygenated derivatives. Essential oils are volatile organic liquids. There are absolutely NO HORMONES (at least not human hormones) OR VITAMINS in essential oils. In addition, of these 3 most common EO elements, Oxygen is the LEAST frequently occurring. If you are just counting types of atoms in the essential oil molecules, Hydrogen is the most prevalent atom followed by Carbon, then Oxygen (again just counting numbers of atoms, not a weight comparison). A large percentage of all essential oil molecules are hydrocarbons (monoterpenes and sesquiterpenes) and don’t even contain Oxygen at all. When the molecules do contain Oxygen, the ratio typically ranges from 1 or 2 atoms of Oxygen to say 10 to 17 atoms of Carbon and 18 to 26 atoms of Hydrogen (for the most common cases of oxygenated mono and sesquiterpenes). Furthermore, the Oxygen in essential oil molecules is BOUND OXYGEN not really available to be delivered in the form of free oxygen radical or oxygen molecules (of course there an infinitesimal amount of dissolved oxygen molecules in just about any liquid but this is insignificant) and thus not very “oxygenating.” It is still unclear to me what the basis for these claims concerning essential oils are coming from and would love to know the literature sources that the claimants are citing as their support. I could go on more about this topic but Robert Tisserand has already written an excellent response to the “Oxygenating” myth on his website, so rather than re-invent the wheel I will refer all of you to read his comments there.
The Ananda Apothecary may be a slightly lesser-known name and strangely hard to pronounce. However, it’s a company of true essential oils people where you can buy almost any type and variety of essential oil you can imagine. Most importantly, they offer wild crafted essential oils, which are oils made from wild harvested plant materials and not plants grown on farms. You can also purchase organic oils certified by both the USDA and Ecocert ICO, and specially AGED essential oils. If all of these things are new to you, find more details in my full brand review here.

Secondly, if we look at the structure of sclareol shown below we will see that it actually has very little in common with the structure of any of the estrogen molecules, E2 being the one that it would have the most in common with because both are what we would call “diols” meaning there are two alcohol groups. Sclareol is not a steroid but what would have to be termed a diterpene diol, not even remotely close to the necessary steroidal backbone.
Estrogenic and antiandrogenic activity have been reported by in vitro study of tea tree oil and lavender essential oils. Two published sets of case reports suggest the lavender oil may be implicated in some cases of gynecomastia, an abnormal breast tissue growth in prepubescent boys.[44][45] The European Commission's Scientific Committee on Consumer Safety dismissed the claims against tea tree oil as implausible, but did not comment on lavender oil.[46] In 2018, a BBC report on a study stated that tea tree and lavender oils contain eight substances that when tested in tissue culture experiments, increasing the level of estrogen and decreasing the level of testosterone. Some of the substances are found in "at least 65 other essential oils". The study did not include animal or human testing.[47]
