The information which follows is not intended to be an argument about whether you should or should not ingest essential oils, but about sifting the information out there which might influence your choices.
Ok, first of all, there are no essential oils with dietary supplement labels sold by any company which the suggested use on the label directs one to add 10 drops to water multiple times per day. In fact there are none which give a suggested dosage on the label of 10 drops at all, much less added to water multiple times per day, so this is an exaggeration to say the least. It may be true there are some individuals who recommend adding 10 drops of an essential oil to your drinking water and doing this multiple times per day. The unspoken implication here is that typical recommendations for water consumption are 8-10 8 oz glasses per day so that could be 80-100 drops of essential oil per day. There are 100 drops of oil in a 5 ml bottle. One company which offers Frankincense oil as a dietary supplement is priced at $29.75 for 5 ml wholesale and $39.14 retail. The suggested use is 1-2 drops, up to three times per day, not 10 drops multiple times per day equaling possibly an entire 5 ml bottle a day.
Secondly, it needs to be understood that there are a whole range of dietary supplements out there, and different people take them for different reasons. However, no one takes the maximum dose of every single dietary supplement they might decide to try, every single day for the rest of their life. Much less some highly inflated dose that is drastically different from what the label recommends. Especially when the cost of this ridiculously inflated dose could be $30 or more per day. No one is doing that, and even if they wanted to, it would be cost prohibitive. Besides the very obvious fact that 100 drops a day would be a toxic dose for almost any oil, especially if continued for multiple days indefinitely.
Now lets examine the logic that ingesting frankincense oil is equivalent to ingesting turpentine because both happen to be high in terpene molecules. Following a similar logic we could argue that house cats are potentially as dangerous as lions and cougars because they are all members of the family Felidae and share many characteristics. They are all carnivores with fur, four paws and a tail, and they all have sharp teeth and claws. They all growl when they are mad. Neither is it just size that makes one potentially more dangerous, as there are many species of wild cats similar in size and appearance to house cats which are quite vicious.
Ok, so how about the argument that you should not ingest solvents? That sounds like a bad idea, right? However, a solvent is merely the liquid in which a solute is dissolved to form a solution. WATER is a solvent and we all drink that and need to.
Now lets consider a seemingly harmless substance regularly consumed by most Americans. Did you know that according to the USDA, the average American consumes 150-170 POUNDS of sugar per year? Just imagine if you took 30 or more 5 lb bags of sugar and stack them in the corner of your kitchen on New Year’s Day and declare to yourself that you are going to eat all of that by the end of the year. Sugar causes many more health issues than essential oils and these issues are well documented.
In many social media groups and blog posts you hear horror stories of people having holes burned in their esophagus, kidney and liver destroyed etc etc. Often people “know” this so and it is “proven” that essential oils caused these issues because they heard it from their best friend whose aunt’s doctor had a patient who suffered these consequences of essential oil ingestion. In some cases people say it is their own first hand story of what happened to them and they know it was the oils and their doctor agreed it was the oils that caused their issues.
However, it is nearly impossible to find documentation of medical reports or published peer-reviewed studies to confirm these reports, while at the same time, such information abounds for many prescription drugs, foods, and other products. Key information such as age and previous health history such as being a cancer survivor (no one is cured from cancer, they are only said to be in remission if the cancer goes away); family history of kidney or liver disease, medication history, or a host of other issues are often not taken into consideration when someone posts a claim stating they know their issue was caused by essential oils. Also missing is key information on which oil or oils were used, brand, quality, dosage, duration, and other factors which might be pertinent. Instead you see statements like “”lemon oil will dissolve a styrofoam cup! Imagine what it would do to your insides!”” (Never mind that our intestines are not made of styrofoam).
According to analysis conducted by Transparency Market Research, the global essential oil market is expected to reach $24.79 billion by 2022. According to Grandview Research, the essential oil market in the US is expected to reach $7.34 billion by 2024 while the US population is projected to reach 334.5 million by 2020. Although current and projected essential oil use includes a wide range of quality and purity, it is not difficult to see that use is certainly widespread enough that if essential oils really were causing a fraction of the health issues claimed in these Facebook groups and blog posts, real proof and documentation that these adverse events were occurring would not be so difficult to find.
A lot of very misleading information is posted on these threads, particularly when understanding what it means to say essential oils are concentrated, and unfortunately, people are drawn in by it. One blog proclaims that a single drop of lemon essential oil is the equivalent of eating 20 lemons! This is incorrect. Dr. Jean Valnet, a medical doctor who practiced aromatherapy for more than 30 years and who was considered one of the leading authorities in the world on essential oils and their therapeutic use, stated that about 3000 lemons were required to distil one kilogram (2.2 pounds) of essential oil. This works out to about 50 lemons per 15 ml bottle, or per 300 drops; 5 lemons per 30 drops, or 1 lemon per 6 drops. In other words consuming a drop of lemon oil is nothing like eating 20 whole lemons, it is like adding one small slice of lemon to your water or tea, a fairly common practice.
And while some may argue that essential oils added to foods are trace amounts measured in parts per million, the truth is most are proprietary formulas and don’t really state how much is in them. Many essential oils have been ingested in foods and home remedies for hundreds of years, well before the term “aromatherapy” was coined. That is not to say that one should ingest essential oils without investing in the training and/or research to learn about the oils you are using and why you might ingest them. What is right for one person may not be right for another. However, exaggerated safety claims promote drama, not education.
Forgotten – Essential Oils and the US Government’s Little Known Role – Essential Oils During the Past Century Part III
What was happening in America with essential oils during the time when the Gattefossé brothers were discovering their therapeutic benefits? The first Pharmacopeia in America was published by the Medical Society of Massachusetts in 1808, followed by the very first United States Pharmacopeia, published in 1820. The idea of a National Pharmacopeia was first proposed when Dr. Lyman Spalding submitted the idea to the Medical Society of the County of New York. The founding U.S. Pharmacopeial convention was held in Washington D.C. for the purpose of creating a system of standards and a National Formulary. Essential oils were included in these works.
At the time René-Maurice Gattefossé applied lavender oil to the severe burns he suffered in a lab explosion, a number of essential oils had been in regular use by U.S. doctors for more than a hundred years. At that time, the United States Pharmacopeia was revised every ten years. During the first hundred years oils were included as individual pure volatile oils with directions for steam distillation, as important components for medicated waters, medicated spirits, liniments, ointments and other compounds. About 10 oils were included in the 1808 Pharmacopeia of Massachusetts. A few of the less common oils would come and go but overall the number of oils climbed over the years, peaking in 1890 with around 44 oils mentioned. However, by this time, synthetic and artificial forms of wintergreen were included, and the 1900 version included several more synthetic forms and isolated components of volatile oils. By 1910 the number of individual pure distilled oils had tapered off to about 35 while synthetic and artificial versions and isolated components continued to increase. Later, the publications of the United States Pharmacopeia and the National Formulary were joined into one volume and published annually.
In 1900, Congress transferred 400 acres of the historic Arlington estate in Virginia to the Secretary of Agriculture for use as a general experimental farm. The Pentagon is now located on this site. This became one of several sites where the U.S. Government conducted what they referred to as “drug plant investigations”, which would continue for more than 50 years, managed by the Bureau of Plant Industry which was established in 1901. The U.S. Government was in fact growing medicinal plants for research purposes, and among The Bureau of Plant Industry’s other projects studying various crops, farming methods, plant diseases and so forth, the project for drug plant investigations specifically included a number of experimental stations, ranging from botanical gardens to small farms used for the cultivation of aromatic plants, which they steam distilled to produce essential oils. Some were researched for perfume, fragrance, and food flavorings, while others were recognized by the government for their medicinal and therapeutic properties. Several government reports and bulletins were published mentioning details of cultivating aromatic plants for producing essential oils, and the methods and equipment for distilling them.
In 1906, the Food and Drug Administration (FDA) was signed into law by President Theodore Roosevelt with the Pure Foods and Drugs Act, which prohibited interstate commerce in foods or drugs which were misbranded or adulterated. While the law was intended to protect the consumer from unnecessary and potentially harmful additives to foods and drugs, the FDA sometimes had their own way of regulating this. One of the early problems they sought to solve began in 1907 with the certification of food colors. Merchants had begun a practice of injecting foods with dyes to enhance their appearance and make them more appealing to the consumer, and to cover up defects. Dyes were also added to drugs. Some of these dyes were quite harmful and so the FDA, instead of forbidding the practice of adding these chemical dyes, they decided they would screen them all and certify which ones could be used. In 1928 they certified more than 600,000 pounds of dyes permitted for use in foods and drugs. (The Arlington Experiment Farm, U.S. Department of Agriculture Handbook for Visitors, 1928). This was thought to be a great improvement because the certification rules were so strict.
Dyes were then also added to cosmetics and the practice of using FDA certified dyes continues today. A huge list of these dyes which the FDA has removed from the list or added further restrictions due to safety issues and problems discovered after they had been in use for some time may be found on the FDA’s Color Additive Status List. The FDA collects substantial fees for color additive certification which are regulated under Title 21 Code of Federal Regulations Section 80.10 They get paid by the pound for these certifications and just in the quarter from Oct 1- Dec 31 2015 certified more than 6 million pounds of dyes added to foods, drugs, and cosmetics. In recent years, the safety of dyes remaining on the FDA’s approved list has come into question. The Global Healing Center, Center for Science in the Public Interest, Dr. Oz and Dr. Mercola are just a few who warn of the dangers of several dyes the FDA still allows.
The more extensive Food, Drugs and Cosmetics Act was signed into law by President Franklin D. Roosevelt in 1938. This law required FDA approval before any new drug could be brought to market, and also prohibited false therapeutic claims. Through the years, the FDA has developed a very broad interpretation of this law which includes prohibiting therapeutic claims that are true, and by defining any random product as a drug if you intend to use it for something they consider a disease. This also includes a long list of words which could be associated with various diseases. For instance, if you use something to help with inflammation or joint pain, in the eyes of the FDA that product is likely to be considered to have become a drug. In 2010 for example, the FDA sent a warning letter to Diamond Foods declaring that their walnuts had become drugs due to therapeutic claims they had on their website based on extensive scientific research. The FDA collects substantial Application, Product, and Establishment Fees for each new drug. In addition, Product and Establishment Fees are assessed annually. In 2014, the most recent year for which a financial report is available, the FDA collected more than $796 million in prescription drug user fees. 45 new drugs were approved by the FDA for 2015. FDA approved drugs, used as prescribed, are, according to their own website the 4th leading cause of death in America.
Meanwhile, in 1939, the work of the Arlington Experimental farm was transferred to the Research Station at Beltsville, Maryland. By 1952, the Bureau of Plant Industry had a 14,000 acre Agricultural Research Center at this location with 2100 employees, of which more than 900 were scientists. Experiments on growing aromatic medicinal plants and distilling their essential oils were still being conducted at this time. The next year, 1953, the Bureau of Plant Industry became part of the Agricultural Research Service, (ARS) which continues to the present. Both the U.S. National Library of Medicine and the National Agricultural Library are filled with peer reviewed clinical studies which have been done on various medicinal and therapeutic uses of essential oils. Some of these studies are done by ARS scientists. The interest in scientific research on essential oils and the growing body of evidence that they do have valuable therapeutic uses continues to expand despite the FDA’s proclamation that only a drug (approved by them, and at great expense paid to them) can be used to prevent, treat, cure, or mitigate a disease.
Unfortunately, the essential oil research and experiments conducted by the U.S. Government were little known and mostly buried in obscure government reports and bulletins which few average citizens had access to, or took the time to wade through them if they did. With the development of the pharmaceutical industry, the major focus became isolating active compounds of various essential oils believed to be responsible for medicinal effects, and creating synthetic versions which could be approved by the FDA as new drugs. Synthetic versions were also often used for food additives and flavorings, as well as for perfumes and fragrances. Thus, despite the government’s role, the essential oil industry in the U.S. was following a very different path than the one in France influenced by the research René-Maurice Gattefossé. Pure essential oils were very scarce in the U.S. Their therapeutic properties were largely forgotten, and the development of aromatherapy would take many decades before finding its way to the U.S.
