You might be able to address toenail fungus at home using certain essential oils and other agents with antimicrobial and antifungal activity, such as Vicks VapoRub.
Toenail fungus, medically known as onychomycosis, is a frequent fungal infection of the toenail. The most obvious sign is a white, brown, or yellow discoloration affecting one or more nails. The infection can spread and lead to thickened or brittle nails.
Sandal season or not, toenail fungus is rarely welcome when you inspect your feet. There are various treatments available, and some are natural options you can try at home.
Which home remedy kills toenail fungus?
Below are 10 at-home approaches for addressing toenail fungus:
1. Vicks VapoRub
Vicks VapoRub is a topical ointment. Although formulated to relieve cough symptoms, its active compounds (camphor and eucalyptus oil) may help combat toenail fungus.
An older 2011 study reported that Vicks VapoRub produced a “positive clinical effect” in treating toenail fungus. Another study in people living with HIV supported this observation.
To use it, dab a small amount of Vicks VapoRub onto the affected nail at least once daily.
2. Snakeroot extract
Snakeroot (Ageratina pichinchensis) extract is an antifungal derived from plants in the sunflower family.
A 2008 study found that snakeroot extract was as effective against toenail fungus as the antifungal medication ciclopirox.
In that trial, snakeroot extract was applied to the affected area every third day during the first month, twice weekly in the second month, and once weekly in the third month.
A further study in people with diabetes mellitus confirmed these results.
3. Tea tree oil
Tea tree oil, also called melaleuca oil, is an essential oil with antifungal and antiseptic properties.
According to the National Center for Complementary and Integrative Health (NCCIH), some small clinical trials indicated that tea tree oil might be effective against toenail fungus.
Apply tea tree oil directly to the affected nail twice daily using a cotton swab.
4. Oregano oil
Oregano oil contains thymol. A 2016 review noted that thymol possesses antifungal and antibacterial activity.
To use oregano oil for toenail fungus, apply it to the affected nail twice daily with a cotton swab. Some individuals combine oregano oil with tea tree oil.
Both oils are strong and can cause irritation or allergic reactions. Using them together may raise that risk.
5. Ozonized oils
Ozonized oils are carrier oils like olive or sunflower oil that have been infused with ozone gas.
According to research, brief exposure to low concentrations of ozone can inactivate many organisms, including fungi, yeasts, and bacteria.
6. Listerine mouthwash
Listerine mouthwash may help treat toenail fungus because it contains menthol, thymol, and eucalyptus, which have antibacterial and antifungal effects. This likely explains its popularity as a folk remedy for toenail fungus.
Proponents suggest soaking the affected foot in a basin filled with amber-colored Listerine for 30 minutes daily.
7. Garlic
Some studies suggest garlic extract might have antifungal effects, though more research is required to confirm this.
One at-home approach is to place chopped or crushed garlic cloves on the affected nail for 30 minutes each day.
Alternatively, and less odorously, you could take garlic capsules as directed by the product manufacturer to treat the condition from the inside out.
8. Apple cider vinegar
Evidence for vinegar as a treatment for toenail fungus is mostly anecdotal. A 2017 study suggested apple cider vinegar has antimicrobial properties, but more research is necessary to determine its efficacy against toenail fungus specifically.
If you decide to try vinegar, soak the affected foot in a solution of one part vinegar to two parts warm water for up to 20 minutes daily.
9. Probiotics
Research indicates that probiotics may help inhibit the growth of various fungi, which could reduce the likelihood of infection.
Consider increasing intake of probiotic-rich foods or taking probiotic supplements as a preventive measure.
10. Other natural options
There are a few additional plant-based remedies that may be useful for treating toenail fungus, according to research. These include:
- spirulina (Arthrospira maxima)
- spruce tree resin
- propolis extract
When to see a doctor
In most situations, toenail fungus is mainly a cosmetic concern. However, it can lead to serious complications for some people.
People with diabetes have an increased risk of developing toenail fungus. Such infections can, in turn, contribute to diabetic foot ulcers.
Avoid using home remedies for toenail fungus if you have diabetes or a weakened immune system. Contact your healthcare provider for appropriate management.
Frequently asked questions
Does hydrogen peroxide help toenail fungus?
A study of a novel medication that slowly releases hydrogen peroxide found it to be about 40% more effective than amorolfine (Curanail, Loceryl, Locetar, and Odenil) after 6–12 weeks, and 70% more effective at 6 months. However, that product (Mycosinate) may not yet be commercially available.
That research did not examine applying hydrogen peroxide directly to toenail fungus. The Global Nail Fungus Organization does list hydrogen peroxide as a potential remedy.
What absolutely kills toenail fungus?
Prescription oral antifungal drugs like terbinafine (Lamisil) or fluconazole (Diflucan) are commonly used to treat toenail fungus and generally resolve it more quickly and effectively. However, they can cause significant side effects such as stomach upset, dizziness, severe skin reactions, and jaundice. This risk may lead many people to try home remedies instead.

How do you get rid of toenail fungus fast at home?
To eliminate toenail fungus rapidly, you will most likely need prescription medication from a doctor, such as fluconazole (Diflucan). Natural treatments might relieve symptoms, but their effectiveness is uncertain, and if they work, they usually take longer.
The bottom line
Home remedies may help with mild-to-moderate toenail fungus and often have fewer side effects than prescription therapies, but there is less robust scientific proof of their effectiveness.
Many factors affect treatment success, including how well the nail permits penetration, the severity of the infection, and overall health.
Home remedies generally take longer to eradicate toenail fungus than prescription topicals or oral systemic antifungals, and visible improvement may take several months. Recurrence is common.
After the infection clears, keep your toenails clean, dry, and neatly trimmed.
Severe toenail fungus can cause pain and permanent nail damage. If home treatments fail or cause adverse effects, see your doctor.
