Are Essential Oils Good or Bad for Your Lungs? Experts Weigh in on the Safety of Diffusing Essential Oils
Are Essential Oils Good for Your Lungs?
“There just isn’t a sufficient body of evidence to support their routine use for the promotion of lung health,” says Dr. Russell Buhr, MD, assistant clinical professor of medicine in the division of pulmonary and critical care at the David Geffen School of Medicine at UCLA in California. Dr. David Beuther, MD, a pulmonologist at National Jewish Health in Denver, Colorado, agrees: “They don’t appear to have much of any therapeutic benefit, so they’re not going to help you.”
If You Have an Existing Lung Condition Like Asthma, Read This
If you have a lung condition, hold up. Lung health experts are more cautious about the use of essential oils by people who have lung conditions like asthma or chronic obstructive pulmonary disease (COPD).
According to Melanie Carver, vice president of community health services for the Asthma and Allergy Foundation of America, the evidence that essential oils could help asthma just isn’t there.
“In fact, breathing in the particles released by the oils may actually trigger airway inflammation and asthma symptoms,” she says. “The strong odors emitted by essential oils may contain volatile organic compounds, or VOCs. VOCs are chemical gases that worsen air quality and can irritate the lungs.”
Adds Dr. Neha Solanki, MD, a pulmonologist with the Cleveland Clinic Asthma Center in Ohio, “Specifically, diffused eucalyptus and lavender release terpene, toluene and benzene. We know that these compounds have respiratory side effects. For example, terpene can cause shortness of breath, chest tightness and wheezing.”
Fragrance is indeed on the list of common asthma triggers, according to the Centers for Disease Control and Prevention (CDC), along with to***co smoke, smoke from burning wood or plants, mold, pets, dust mites and air pollution.
So, if you have asthma, you could unintentionally trigger an asthma attack by breathing one of those oils that’s been warmed up and diffused through the air.
Consider the Lack of Regulation for Essential Oils
Doctors regularly cite the lack of regulation as another reason to be cautious about using essential oils for your lungs, or in general. “These products are largely not regulated by the Food and Drug Administration, so there is no way to confirm what’s in the bottle is what they say is in the bottle,” says Dr. Buhr.
You could be getting a very diluted oil or one that’s much more concentrated—and it’s hard to know, adds Dr. Beuther. You might not be able to get the exact same concentration of the same oil from purchase to purchase.
That’s a big contrast to the medications that your pulmonologist will prescribe for you, says Dr. Solanki. “The medications that physicians use for asthma treatment are backed by the FDA,” she says. “This means that there are numerous clinical trials that have proven the safety and efficacy of the medications prescribed by medical professionals.”
Could the Evidence Change for Essential Oils and Lungs?
For now, doctors are suggesting people with lung health issues either avoid essential oils or approach them with extreme caution, due to a lack of solid evidence proving any benefit to the use of essential oils for lung health. But could new research make an impact? Perhaps.
“There is potentially some research that is still in early phases where they could still have some potential benefits,” says Dr. Buhr. But wait. Those “early phases” usually mean research that involves petri dishes or animals, not humans, he notes. “There’s definitely a role for continued exploration for the role of botanicals as treatment, but that doesn’t mean they’re ready for prime time” with current available preparations, he says.
The bottom line: it’s a good idea to be cautious about using essential oils if you happen to have a lung disease or condition. Talk to your healthcare provider before you start using anything new, including an essential oil or herbal supplement.
And don’t give up on any of the prescribed meds you’re taking without consulting your doctor first. If you’re concerned about a side effect of your current medication, your doctor may be able to find a different medication that might be better for you.
