“There is definitely credible science behind certain benefits for certain essential oils,” says Cynthia Bailey, MD, a dermatologist in Sebastopol, CA. “But you have to choose wisely, and you cannot use them indiscriminately.”
As far back as 1,000 A.D., healers used mechanical presses or steam to extract essential oils from aromatic plants. Today, practitioners can rub oil-infused lotions on the skin, where the compounds are absorbed into the bloodstream. Or they can diffuse them into the air where, once inhaled, they bind to smell receptors and stimulate the central nervous system,
Ill-informed at-home users tend to misuse them. One group of concerned aromatherapists began collecting injury reports online. Since the fall of 2013, it has received 229, ranging from mild rashes and anaphylactic shock to internal chemical burns from using oils to treat vaginal yeast infections.
Essential oils are very safe and effective if used properly for addressing routine health challenges. But there is so much misinformation out there right now,
Contrary to what several essential oil companies recommend, the oils generally should not be swallowed. The body absorbs more this way, boosting the chance that they will interact with medications or cause an allergic or toxic reaction. Even continued exposure to small amounts (a few drops a day in a water bottle) can lead to fatigue and headaches. Taking in larger amounts of certain oils — like tea tree oil, wintergreen, and camphor — can lead to throat swelling, a racing heart, vomiting, and even seizures, says the Tennessee Poison Center, which saw the number of toxic essential oil exposures double from 2011 to 2015.
The oils, which are derived from plants and used in aromatic and homeopathic products, can cause harm when consumed. And children face a heightened risk from exposure, the experts said.
“The rule of thumb in toxicology is ‘the dose makes the poison,’ so all essential oils are potentially harmful,” said Dr. Justin Loden, a certified specialist at Vanderbilt University Medical Center’s Tennessee Poison Center.
Some essential oils, like eucalyptus, contain compounds called phenol that can irritate the respiratory tract if inhaled, particularly for babies. And some have hormone-like properties that studies suggest could harm children and pregnant women.
Allergic reactions are also common. Bailey has seen rashes on eyelids from essential oil droplets emitted by diffusers and around mouths from peppermint oil-infused mouthwash or lip balm.
Highly toxic essential oils include camphor, clove, lavender, eucalyptus, thyme, tea tree, and wintergreen oils, the researchers noted. Many essential oils can cause symptoms such as agitation, hallucinations and seizures. Symptoms may also include chemical burns, breathing problems, liver failure and brain swelling, among others.
To keep kids and pets safe, store essential oils properly — locked and out of reach. Follow instructions regarding their use, and seek help by calling Poison Control (1-800-222-1222 in the United States) in an emergency.
