Knowing and trusting the company or companies you purchases your essential oil products from is crucial in this industry and I have and continue to use numerous different brands of essential oils. Early on in my essential oil journey, I began using Young Living essential oils because they were the best, most pure, therapeutic grade essential oils and the company owned their own farms.
Earlier this year in January, when I was working on my first aromatherapy certification, I contacted Young Living specifically to ask what chemotypes their Rosemary, Basil, and Thyme since they were not on the label or website and they do not provide GC/MS reports on their website or by request.
For your reference: “A chemotype occurs when a plant of a specific genus and species produces a particular chemical in a higher than normal amount because of geographic location, weather, altitude, insect and environmental interactions, and the like. A chemotype is not a different species or genus, nor is it a type of chemical; it is merely a chemical anomaly within the plant that occurs naturally.” -[ The New York Institute of Aromatic Studies, Aromatic Scholars program.] To learn more about chemotypes of certain essential oils, please read my previous blog post: What are Essential Oil Chemotypes?
Young Living’s Product Support responded in February saying that “We do not have a specific chemotype for our essential oils available to provide as we do not standardize our essential oils by chemotype. However, we are able to provide the key constituents on a specific oil you have concerns regarding. “
This did not sit well with me because it seemed as if they didn’t really have a good understanding of what chemotypes were at all. How can you standardize something that occurs in nature based on things like weather and whatnot. I even inquired with my colleagues and aromatherapy instructors all of which agreed that this claim makes no sense -- I even asked Robert Tisserand during one of the weekly Q&A sessions during the Essential Oils Safety Masterclass and he said that it "made no sense."
Young Living does not release their GC/MS reports to the public, so there is no way to confirm this information, but it would appear (in the past) that even if they do not standardize oils by chemotype that their Basil is high in Methylchavicol, Rosemary with 1,8 cineole, and Thyme with thymol.
Fast forward a couple of months, I followed up with a few questions:
I was told that " We do not have a specific chemotype for our essential oils available to provide as we do not standardize our essential oils by chemotype. However, we are able to provide the key constituents on a specific oil you have concerns regarding." I was given the corresponding chemical constituents for the oils requested (Rosemary, Basil, and Thyme). But the first statement is concerning to me as chemotypes are very important to know for these essential oils."
"You should be able to tell customers what chemotypes of oils that you are selling. This is not a standardization, chemotypes occur in nature due to a variety of factors including: chemical composition including environmental conditions such as light, soil, temperature, moisture, climatic influence and altitude as well as geographic area.. Many essential oils have chemotypes and it is always important to know which one you are working with as therapeutics and safety may differ. Do your chemotypes stay the same? Do they change depending upon the harvest? This information is hard to ascertain since you do not publish your GC/MS reports."
To which Young Living Product Support responded:
"Young Living® no longer standardizes its essential oils by chemotype (CT). Chemotype is another name for chemical variety (a specific variety of a plant species based on chemical profile). Young Living has adopted the use of "Seed to Seal®" to standardize its essential oils by. Seed to Seal includes standardization by chemical profile as well as growing conditions, distillation, and manufacturing process."
I responded again with:
"This seriously makes no sense, while yes, a chemotype is a chemical specificity or variety, it is one that is based on numerous factors. For your reference: A chemotype occurs when a plant of a specific genus and species produces a particular chemical in a higher than normal amount because of geographic location, weather, altitude, insect and environmental interactions, and the like. A chemotype is not a different species or genus, nor is it a type of chemical; it is merely a chemical anomaly within the plant that occurs naturally."
"So unless you can control the weather and the aforementioned factors, I am suspect about your claims that you can "standardize" your oils by "Seed to Seal" without altering the chemical makeup of the oil artificially. I understand that some aspects can be controlled, but you cannot account for one crop having had more rain than another and have it not have a relative chemotype."
"I would like further clarification upon this subject because there are vast different therapeutic properties for different oils with chemotypes. For instance, Rosemary can be used for hair growth - this is true of the verbenone chemotype, but not 1,8 cineole or camphor chemotypes. This is particularly frustrating since Young Living does not share its GC/MS reports with the public."
I am rather frustrated and disappointed that they could not answer a simple question and seem to not even be all that educated in the science of essential oils, which is also a bit off-putting since they are one of the biggest essential oils companies in the world and like to claim that their oils are the most pure, the most therapeutic grade, and seed to seal.
Finally in August they replied….
"We recognize that pure essential oils will have natural variances in chemical makeup from batch to batch caused by many different factors including time of harvest, amount of sunlight, amount of water, geographical location of harvest, etc. However, our Seed to Seal® quality commitment ensures that every batch of oil contains the optimal levels of natural bio-active compounds. We verify the chemical constituents of each batch through testing before we begin selling the oil. From this information, we can assure you that the active constituents in each batch and bottle of essential oil meet our specifications and thus have the same therapeutic value."
"The key constituents for Basil, Rosemary, and Thyme given to you past provided the ranges for the levels of those constituents which were considered within our Seed to Seal specifications at that time. Due to a recent change in company policy, we are no longer able to provide ranges for the chemical constituents in our essential oils. This information is now regarded as proprietary as it discloses the constituents we deem most therapeutic in value, and therefore the information is considered trade secrets. Patents and trademarks do not adequately protect this information, as you cannot patent or trademark an oil."
So after close to 9 months, I still have no answers, and they seem to be stuck on seed to seal trumping chemotype considerations which occur naturally due to a variety of environmental effects. This is why companies need to provide GC/MS reports on their website or at the very least by request. This is not proprietary information. The "because we are awesome and we say so" argument does not hold up here at all. I am highly disappointed by their responses and lack of actual information beyond the company marketing lines.
