Tisserand and Balacs further point out that “the only likely risk would be from prolonged exposure (perhaps 1 hour or more) to relatively high levels of essential oil vapor which could lead to headaches, vertigo, nausea and lethargy”. With regard to internal use, NAHA does not support the indiscriminate internal use of essential oils. Click here for more information.
The good news is that the guessing work will be gone in the next few years. Gary Young, founder of Young Living has been asked by the FDA to set up a standards for the United States. So it will not matter what the customer service or distributors say as we will be able to refer to the FDA classify the oil. This will make the true pure oils to stand up and be noticed but also for safety for our health to take the purest of the pure oils for our medicines!
Do not use essential oils internally unless directed by a qualified practitioner or using a professionally formulated blend labeled for internal use. Safety Guidelines for dilution and use must be followed. Any essential oils used must be pure and genuine. NAHA recommends purchasing from a reputable supplier who analyzes their oils by GC/MS. Please visit NAHA's approved schools to explore education in aromatherapy.
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]
#1- Therapeutic Grade is just a selling gimmick. If EO’s are pure, they are equal to any other. There are only a few distillery’s so many of the EO’s come from the same distillery then sold under several names. You should always buy from a company that is willing to give you the GC/MS reports regarding the Lot your EO bottle is from. That tells the constituents of the EO and would indicate if adulterated in any way.

Essential oils are not really oils. They do not contain the fatty acids that constitute what we would consider an actual oil. Valerie Gennari Cooksley, author of Aromatherapy: Soothing Remedies to Restore, Rejuvenate and Heal defines essential oils as “highly concentrated plant constituents possessing potent medicinal and cosmetic qualities.” However, I think Stephanie Tourles nailed it in Organic Body Care recipes when she said, “I consider essential oils the life force or the soul of the plant.”

With a fresh zesty scent of citrus and fruity top notes, Grapefruit Essential Oil is popular when scenting facial cleansers and toners. Grapefruit Essential Oil is used in aromatherapy to bring about a cheerful feeling. There is no difference between the quality of the White and Pink varieties, but the Grapefruit Pink Essential Oil is generally considered the sweeter of the two oils. Grapefruit oil is also sometimes added to creams and lotions as a natural toner.

I had been using another brand of Frankincense prior to buying this product, and although I saw some evidence it was working on a suspicious-looking growth that appeared on my arm, it was a slow process. When I purchased this one and began applying it, the difference in quality was very evident. This certified organic Boswellia Serrata (Frankincense) is head and shoulders above any other Boswellia essential oil I have used. It is extracted from the resin.
She was very kind to me and said she had been getting a lot of calls on the release due to essential oils’ popularity. She reported that the piece was meant to highlight her conversations with toxicologists on the increasing use of essential oils and exposure to children. The fact is children getting into the oils and swallowing large quantities is bad. However, this was the misuse of essential oils, not a safety issue with the proper dosing. She stated that she never meant for it to be spun and construed that essential oils were unsafe in general.
“Extending”, “cutting” or “stretching” which is diluting an oil with a vegetable oil, an isolate from another, cheaper oil, the whole of another cheaper oil, alcohol or other solvent. An oil extended with vegetable oil will leave a stain if dropped on a piece of paper, although this test works better for clear oils like Rosemary (Rosmarinus officinalis), than for darker oils like Patchouli (Pogostemon patchouli). Other forms of adulteration are more difficult to detect without the use of gas chromatography and much experience.
Thanks for the informative article on essential oils! I want to know if there are any essential oils that can be applied on my skin (face) just before my skin is exposed to direct sunlight? I know that the skin where citrus oils are applied should not be exposed to direct sunlight for few hours after application. That’s the only question that I am concerned with because I am very interested in concocting a facial oil moisturizer after reading an article of yours that is about making a “3-ingredient facial oil moisturizer”.
Florasol is another solvent used to obtain essential oils. It was originally developed as a refrigerant to replace Freon. Although Florasol is an "ozone-friendly" product, it has a high global warming potential (GWP; 100-yr GWP = 1430).[11] The European Union has banned its use, with a phase-out process that began in 2011, to be completed in 2017.[12] One advantage of Florasol is that the extraction of essential oils occurs at or below room temperature so degradation through high temperature extremes does not occur. The essential oils are mostly pure and contain little to no foreign substances.[citation needed]
