Toenail fungus, also known by its scary-sounding medical term, onychomycosis, arises from the simplest of causes.
There is a type of fungi, dermatophytes, that can invade the nail bed area under certain types of favorable conditions.
But when you have toenail fungus, it doesn’t usually make you feel any better to know you are not alone.
You still want to get rid of it – and as fast as possible!
You may feel embarrassed about how your toenails look or smell, to the point where you don’t even want to seek out a doctor’s help.
The good news is, there is a home remedy you can try that has been effective for many people in reducing or eliminating symptoms of toenail fungus. That remedy is tea tree oil.
In this article, learn more about tea tree oil, what it is, how it works and how it can be effective for treating toenail or fingernail fungus.
What is Nail Fungus?
Nail fungus is essentially an invasion of fungi in the nail area. These fungi get underneath the nail bed on your fingers and/or toes and begin to proliferate.(1)
As the fungi proliferates, the nail bed develops yellow or white spots. In time, the nail bed will thicken and become darker in color.
Sometimes a crust will form or the nail will begin to lift away from the bed beneath it.
In more advanced cases, as the nail lifts away from the bed, you may perceive an odor which is caused by the multiplying fungi.
The most common reason why people develop nail fungus is because of exposure to persistent damp.(2)
For instance, if you do a lot of working out, especially swimming, or you work in damp conditions, or you have a pedicure or manicure in a less-sanitary salon, you can pick up the fungi that cause nail fungus.
If you have any prior history of athlete’s foot, diabetes or a compromised immune system, you may become more prone to nail fungus in the future.
While it is more common to experience fungus in the toenails than in the nails because of footwear (damp socks and shoes or continued immersion in water, for instance) and less robust natural circulation, both are equally vulnerable if conditions are right.
What is Tea Tree Oil?
The tea tree plant has been known for its medicinal properties for more than a century to date. The Australian aboriginal peoples and healers have a long history of using tea tree oil for its healing benefits.
For the past 70 years, medical studies have looked at the health benefits of tea tree oil from various angles.
The National Institutes of Health (NIH) have documented more than 400 medical studies involving tea tree oil for its anti-fungal, anti-microbial, anti-septic and other powerful medicinal properties.(4)
To date, tea tree oil is becoming ever more popular for use in personal care creams, lotions, face washes, shampoos, conditioners and even toothpaste.
Tea tree oil can also be used on a stand-alone basis (so long as your skin isn’t sensitive), as a spray or mixed in with a carrier oil (such as fractionated coconut oil, neem oil, jojoba oil, olive oil, grapeseed oil, almond oil, shea butter and other carriers.
Why Is Tea Tree Oil Good for Nail Fungus?
Tea tree oil is particularly good for addressing the symptoms and underlying causes of nail fungus because of its unique naturally-occurring medicinal properties.
Specifically, tea tree oil is well-documented to provide healing benefits in these areas:(5,6)
» Cicatrisant (heals wounds).
» Balsamic (boosts immune system).
While this may seem like a short list of properties, each cuts right to the heart of what is going on when a foreign body invades the human body.
Whether the invader is microbial, bacterial, viral or fungal in nature, tea tree oil contains within itself the ability to neutralize the invader’s power.
So, for instance, let’s say the onychomycosis fungi invades your toenail bed. Left undisturbed, the fungi will multiply and begin to cause all of the symptoms of toenail fungus (white or yellow spots, thickening, darkening/discoloration, raised nail, odor, et al).
But when confronted with the anti-fungal properties of tea tree oil, the onychomycosis fungi will not be able to continue multiplying and causing symptoms.
This is the power of tea tree oil in a nutshell.
How to Use Tea Tree Oil to Treat Fungal Nail Infection?
If you have never used tea tree oil before, it is always best to start with it in a diluted form to see how your skin will respond. Tea tree oil can still exert all of its medicinal benefits when diluted, so there is no need to expose your skin to irritation or discomfort unnecessarily.
However, if you have previously used pure tea tree oil applied directly to your skin without discomfort, then it is perfectly fine to use it this way to treat toenail or fingernail fungus.
Here are a number of options you can choose from for using tea tree oil to treat nail fungus:
Using an eye dropper, drop one or two drops of pure tea tree oil right onto the bed of the affected nail each day. According to study results, you may need to continue this for up to three months to see the full results.(7)
NOTE: Because you are dropping the tea tree oil onto the nail bed and not the skin around the nail, you can safely try this method even if you haven’t yet used undiluted pure tea tree oil before.
25 to 50 percent dilution.
Consumer Reports outlined the results of the Australasian Journal of Dermatology study where athletes used tea tree oil to resolve fungal infections.(8)
You can also dilute tea tree oil by up to 50 percent in a carrier oil applied twice daily to the affected area to clear up the symptoms of nail fungus.
After just four weeks of application two times per day, the fungal infection was completely gone in more than 50 percent of the study participants.
Cream or lotion.
Adding 100 percent tea tree oil in a cream or lotion preparation with a carrier oil, apple cider vinegar, rose water and/or plain water is another proven method for reducing or eliminating the symptoms of nail fungus.(9)
Combining tea tree oil with other essential oils
Certain other essential oils contain complementary properties to that of tea tree oil, while others have similar anti-fungal and anti-septic benefits that can enhance tea tree oil’s healing powers.
Lavender oil, mustard oil, lemon oil, orange oil, grapeseed oil, oregano oil, garlic oil, peppermint oil and clove oil all make powerful additions to the power of tea tree oil to fight off fungal infections.
Tea tree oil soak.
You can use water, rose water, apple cider vinegar or a combination of all three along with about 5 drops of pure tea tree oil in a foot soak.(10)
Be sure to mix the ingredients well so the oil is diluted before you put your foot in. For the most comfort, you can warm the water/vinegar slightly before inserting your foot.
Potential Side Effects of Tea Tree Oil
Tea tree oil in its natural, pure and undiluted state can cause well documented side effects.(3)
However, dilution using carrier oils, plain water, rose water, apple cider vinegar, baking soda, alcohol, aloe vera, lemon juice and other essential oils can provide the dilution necessary to avoid these side effects while still resolving the fungal issue.
It is important to be aware of tea tree oil’s side effects regardless, because you may need to adjust the percentages of other ingredients to ensure the most healing and yet least irritating effect from using tea tree oil.
Tea tree oil’s known side effects (in its pure state) include these:(6,11)
» Skin dryness.
Also, if you are pregnant or trying to conceive, it is always a good idea to talk with your doctor before trying any new health regimen, including tea tree oil.
Tips to Prevent Toenail Fungus
But once you have achieved that goal, you will want to move forward and take these steps to ensure you don’t inadvertently get reinfected with the fungi again!
