A Doctor’s Take on Essential Oils

Essential oils are all the rage. You know the ones I’m talking about. In fact, you’ve probably been invited to a product party where little vials with expensive price tags promise a wide range of health benefits. You’ve also heard the stories. Essential oils cure warts and ear infections. They soothe rashes and bellyaches. They reduce fever and fight the common cold. Virtually any ailment you suffer has a corresponding dose of liquid magic.

You’ve probably also wondered if essential oils really work. Are they safe? And is buying into the movement a waste of money or an effective use of a natural remedy?

What are Essential Oils?

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.

The U.S. Food and Drug Administration (FDA) classifies essential oils as food supplements, not drugs. This means producers of essential oils are not allowed to market the compounds as medicine. In fact, they must clearly state the product is “not intended to diagnose, treat, cure or prevent any disease.” According to the Dietary Supplemental Health and Education Act of 1994, this classification also means the FDA is not allowed to regulate the sale or use of essential oils unless they can prove a particular product poses a serious threat.

The Mind-Body Connection

The brain plays an important role in the modulation of many symptoms and side effects, such as nausea, pain and stress. Aromatherapy can help patients cope with these problems. In fact, the Massage Therapy Team at Nationwide Children’s Hospital uses several essential oils, including lavender, sweet orange, peppermint and lemon/lime to support the well-being of patients. I’m taking advantage of the mind-body connection right now, diffusing a mixture of spearmint and a proprietary blend called “Breathe” as I write this post. I’m not sure it’s really keeping me on task, but I sure do enjoy the smell.

What About the Treatment of Medical Conditions?

There is no evidence to suggest essential oils are effective (or safe) as the primary treatment of diseases and symptoms that fall outside the mind-body connection. Remember, when you use an essential oil and expect a specific outcome, you are relying on the biochemical activity of the compound in question. Many plants are biochemically active in humans and classified as drugs. These “natural” products have undergone rigorous scientific study to prove they work and determine what dangers they pose.

Essential oils have not been subject to these same methods of study for most medical conditions, so we don’t have reliable and reproducible evidence of their usefulness or safety. Some distributors of essential oils are quick to show “studies” demonstrating a compound’s effectiveness, but this data is unlikely to stand up to scientific scrutiny.

At the end of the day, essential oils (like all medication) are chemical compounds. This begs the question: which do you trust more… compounds proven to work with known side effects (so you can make an informed decision with regard to benefit and risk) or compounds whose usefulness and safety aren’t really known?

Nothing New Under the Sun

The notion of using essential oils as a replacement for standard medical therapy is not new. Today’s essential oils are yesterday’s herbal remedies. They’re your grandmother’s swamp root, your great-grandmother’s liver pills and your great-great-grandmother’s snake oil (hey, at least we made it back to oil). And as in those days, somebody’s getting rich selling their wares. Why? Because there will always be folks who claim they work and others who buy into the claim looking for a quick fix. My question for believers in the crowd: how do you know the remedy really did the job? Runny noses get better. Coughs and bellyaches go away. Rashes clear up, skin heals and behavior fluctuates.

As an aromatic food supplement, essential oils are a playground for the nose and probably safe in small quantities. They may be useful in modulating the mind-body connection, but as primary medical treatment for most disease conditions, there is no evidence to suggest they work. I’d recommend spending your hard-earned money on chemical compounds that do.

    “After all, if the producer of an essential oil truly believes the compound has a reliable effect, why not rigorously test it, submit an application to the FDA, and sell it as an actual medicine?”

    For the last 100 years we have been medicine dependent. How did we survive before then? Using
    yesterday’s herbal remedies, herbs and oils.
    We want to take back our health from the horrible cycle of drug dependence – which cause us to need more drugs to treat those side effects. When you extract individual compounds from essential oils or any plant matter, it becomes a drug and not usable by the common person. The compounds in the plants need to be kept together to be used safely, they balance each other so they are not “drug like” but support the bodies ability to heal without side effects. Do we not have over 100,000 olfactory receptor sites for no reason? The aroma alone works miraculously in supporting the bodies health.
    Pharm drugs may save lives temporarily , but are not intended to be used long term. Long term should be a healthy diet with support of super foods that feed, rejuvenate and support the healing of the cell.
    The research being done on essential oils are skyrocketing and have show promising results. This is a very authoritative article about something your seem to know little about, or does it intimidate your that people might not need a doctor of every little sniffle because they are deciding to take charge of their health?
    Look up the number of people who die from properly prescribed drugs compared to using plants therapeutically. There is no comparison- 106,000 to maybe 50 a year respectively reported by AMA Journal. This is using dangerous herbs irresponsibly versus responsibly prescribed medicine.
    So what is wrong with making money teaching people how to use essential oils responsibly when big pharma companies are making billions on the drugs that are killing over 100, 000 a year and get a free pass?
