Seven essential oils to support lung and sinus function during bad air

The Western United States is experiencing one of the worst fire seasons in recent history. Dozens of wildfires are burning across multiple states, taxing wildland firefighters and government resources. With the massive amount of fires burning, air quality in the West has significantly declined, resembling a dark and thick haze, that challenges the respiratory system of even healthy people. Here are seven essential oils that can aid lung and sinus function during these times of bad air.

People most vulnerable to smoky air
While many healthy people remain unaffected by the smoky air, sensitive individuals and those with existing health conditions are the most vulnerable to the negative effects of bad air. Children are particularly susceptible to the harmful effects of smoky air due to their more rapid breathing rate. On the opposite side of life, the elderly — who are more likely to have other health conditions — can easily succumb to bad air. People with heart (heart failure, angina, ischemic heart disease) and lung diseases (asthma, emphysema, pneumonia, bronchitis, COPD) are likely to experience chest pain, coughing, shortness of breath, and wheezing. Pregnant women should also be very cautious in these conditions as the air could potentially affect both the mother and the developing baby. Even healthy individuals aren’t immune to the effects. They can experience burning eyes and throat, chest pain, excess mucus production, and difficulty breathing if too much time is spent outdoors.

How smoky air affects the respiratory system
When wood and other organic matter burns it produces a mixture of gases — fires can boost ozone pollution by releasing nitrogen oxides and hydrocarbons — and particulate matter. These microscopic particles are particularly concerning because they penetrate deeply into the lungs and cause a range of health problems, from a mild runny nose to chronic lung disease. Particulates produced by wildfires promote acute inflammation, oxidative stress, and reduced immune responses to infections according to research. Exposure to fine particles is also linked to cardiovascular disease (1) and premature death. (2) It is best to limit time outdoors when significant smoke is present in the air and sensitive individuals should consider wearing a mask.

Essential oils that support overall respiratory system function
Essential oils are great remedies for the respiratory system due to their volatility. Their volatility allows them to enter both the upper and lower respiratory tract to influence complete respiratory function. In addition, their complexity (from a dozen to hundreds of constituents), multiple mechanisms of action, and multiple cell receptor targets make them an ideal solution to help you breathe easier during the most challenging situations.

Eucalyptus. A hallmark of inflammatory airway diseases is the overproduction of mucus. Eucalyptus essential oils are rich in the important monoterpene 1,8-cineole. (3) Preliminary research demonstrates that 1,8-cineole modulates the expression of genes involved in the production of mucus; therefore, it reduces overproduction of mucus. (4) Other research shows that eucalyptus (Eucalyptus globulus) essential oil prevents lung injury. (5) A standardized supplement called Myrtol  designed to break down mucus and alleviate sinus congestion, and clinically proven in more than dozen trials — containing eucalyptus, orange, lemon, and myrtle essential oils standardized for limonene, 1,8-cineole, and alpha-pinene (300mg, four times daily), significantly reduced coughing fits during the day and night in people with bronchitis. (6)

Myrtle. Used for centuries to treat pulmonary disorders, myrtle essential oil has moderate amounts of 1,8-cineole — depending on whether it is green or red myrtle — but also contains other respiratory-supportive constituents like alpha-pinene and linalool. Regular exposure to ozone and particulate matter has been associated with exacerbation of pulmonary fibrosis and possibly even the development of idiopathic pulmonary fibrosis. (7) A methanolic extract of myrtle, which contains volatile constituents found in the essential oil, reduced inflammation and fibrosis of the lungs in animals. (8) Myrtle essential oil has also been shown to positively influence genes related to the respiratory system. (9)

Balsam fir. Another essential oil that is known to positively influence pulmonary epigenetics is balsam fir. (10) This research supports its traditional use for respiratory disorders, including those involving respiratory spasms. Some scientists report that conifer trees, like balsam fir, cleanse the air around us by trapping particulates and airborne chemicals in their foliage.

Peppermint. Russian scientists found that inhalation of peppermint essential oil reduced symptoms of pulmonary tuberculosis and prevented its recurrence in humans. (11,12) Inhalation of menthol — one of the primary constituents in peppermint oil — significantly enhanced mucus clearance in smokers. (13)

Cinnamon, clove, and thyme. A recent study concluded that the essential oils of cinnamon, clove, and thyme are excellent choices to combat respiratory tract infections in liquid or vapor phase. (14) This means you could diffuse these oils to allow them to enter the respiratory tract and help cleanse the lungs of pathogens. Moreover, these essential oils are known as potent antioxidants, which will help protect against the free radical assaults caused by particulates that enter the lungs. Clove and cinnamon are often combined in immune blends, so you may already have a good option in your essential oil arsenal.

Ginger. Opening the airways can reduce wheezing and difficulty breathing. Preclinical research shows that ginger essential oil can reduce airway constriction. (15) The study authors noted that 1,8-cineole and citral, both present in small quantities in ginger essential oil, each triggered bronchodilation (dilation of the bronchi and bronchioles to improve airflow to the lungs).

How to use the essential oils

  • Diffuse a combination of the above oils for at least 60 minutes, twice daily.
  • Perform a steam inhalation of one or more of the above oils (cinnamon and thyme may be too strong) once daily. The steam may help improve mucus clearance.
  • Dilute and apply eucalyptus, myrtle, peppermint, and ginger to the upper chest, once or twice daily.
  • Consider taking a capsule with one drop each of myrtle, eucalyptus, orange, and lemon essential oils (simulates Myrtol), three to four times daily.


Hopefully, firefighters will get the fires in the West under control quickly. Pray for their safety and ability to do so. But, until then, use your essential oils to keep your respiratory system healthy, particularly if you are among the sensitive populations.*

* Note: If pregnant or under the care of a physician, consult your health practitioner prior to use. Some people with chronic respiratory systems may respond adversely to essential oils, so use with caution and under proper guidance.
