Infection of the ear, also called otitis, occurs most often in children, but it can also affect adults. Ear infections can be challenging to treat.
Essential oils are concentrated liquids that contain extracts of plants from around the world. The manufacturers of these oils often use steaming to separate the natural oils from the rest of the plant.
Essential oils are suitable either for inhaling or for diluting and applying topically. It is vital never to ingest an essential oil.
Researchers have discovered that some essential oils have antibacterial and antimicrobial properties, which may make them beneficial in treating infections.
In this article, we look at the best essential oils to try for ear infections, how to use them, and other natural remedies. We also consider whether or not essential oils are effective and safe to use.
How can essential oils treat ear infections?
Some people find that essential oils can help reduce the symptoms of an ear infection, which typically include pain, swelling, and ear discharge.
Some essential oils have antibacterial or antiviral properties that may allow them to kill bacteria and help fight off an ear infection. Other essential oils may prevent viruses from reproducing.
However, there has been no high-quality research into whether or not essential oils are an effective treatment. Proof of how well they work is generally limited to anecdotal evidence.
Best essential oils for ear infections
Some diluted essential oils may help fight off ear infections when people use them as ear drops or rub them around the ear.
However, there is minimal high-quality, up-to-date evidence that any particular oil is beneficial.
Based on the existing evidence, we look at some of the best essential oils that people can try for ear infections:
Lamigex ear drops
A small-scale 2014 clinical trial compared the effects of standard ciprofloxacin ear infection drops with a mixture containing the following essential oils:
- clove oil, Syzygium aromaticum
- lavender oil, Lavandula angustifolia
- herb-Robert oil, Geranium robertianum
The participants received 3 drops every 12 hours over the course of a week. The researchers found that this mixture, named Lamigex, was as effective as the ciprofloxacin ear drops. Both treatments improved symptoms of tenderness, itchiness, and discharge.
Tea tree oil
Tea tree oil contains an antibacterial substance called terpinen-4-ol.
A review study from 2006 concluded that tea tree oil has antimicrobial and anti-inflammatory properties.
Additional evidence for the antibacterial effects of tea tree oil comes from a 2014 review study, which concluded that tea tree oil may be effective in treating acne, possibly because it kills the bacteria that cause this condition.
However, the researchers say that more research is necessary to validate these findings.
Doctors need more evidence on the effectiveness of tea tree oil before they can recommend it as a treatment option for bacterial ear infections.
Oregano oil
Mexican oregano oil, or Lippia graveolens, may also help with ear infections.
A study from 2011 included in vitro tests of oregano oil, which showed that it had antiviral capabilities.
These effects are primarily due to a component in the oil called carvacrol.
However, this study does not prove that the oil would be effective against ear infections. The researchers state that further research is necessary to determine how effective this oil is.
Basil oil
Basil oil, or Ocimum basilicum, is another essential oil that could possibly help with ear infections.
A study from 2005 found that basil oil was effective in treating ear infections in rats. Researchers used rats with infections from either Streptococcus pneumoniae or Haemophilus influenzaebacteria.
The results indicated that basil oil led to more significant improvements in rats with both types of infection compared to a placebo.
Other oils
There are several other oils that various websites and manufacturers promote. Researchers have carried out studies on some of these oils. However, in most cases, there is no evidence to substantiate the claims that they will help with ear infections.
Some other oils that people have tried or recommended for ear infections include:
- garlic oil
- peppermint oil
- mustard oil
- thyme oil
