Toenail fungus, also known as onychomycosis, is more than just a cosmetic issue. It’s a common fungal infection that affects millions of people each year, leading to thickened, discolored, brittle nails that can even become painful over time. While prescription treatments are available, many individuals prefer natural and affordable home remedies to manage the condition — especially when caught early.
As we enter 2025, science-backed natural solutions continue to rise in popularity. This article explores the 10 best home remedies for toenail fungus, backed by traditional use and recent studies.
1. Tea Tree Oil
Tea tree oil, extracted from the leaves of Melaleuca alternifolia, is known for its potent antifungal and antiseptic properties. Studies have shown that tea tree oil can effectively combat the Trichophyton species, one of the most common fungi behind nail infections.
How to use:
- Clean and dry the affected foot.
- Apply a few drops of 100% pure tea tree oil directly to the nail.
- Let it sit for 10–15 minutes before rinsing.
- Repeat twice daily.
Note: Always do a patch test first, as tea tree oil can cause skin irritation in some people.
Scientific support: A 2013 study published in BMC Complementary Medicine and Therapies found tea tree oil comparable in effectiveness to over-the-counter antifungal creams.
2. Vicks VapoRub
It may seem unconventional, but Vicks VapoRub has gained attention as a toenail fungus remedy. It contains camphor, menthol, and eucalyptus oil — all of which have antifungal properties.
How to use:
- Apply a small amount to the nail and surrounding skin once or twice daily.
- Wear clean socks to avoid rubbing it off.
Research insight: A 2011 study published in the Journal of the American Board of Family Medicine found that 83% of participants experienced partial improvement in fungal symptoms with regular use of Vicks VapoRub.
3. Ozonized Oils
Ozonized oils, such as ozonated sunflower or olive oil, are infused with ozone gas, which is believed to enhance their antimicrobial activity.
How to use:
- Apply a few drops to the infected nail twice daily.
- Massage gently and let it absorb.
Scientific findings: A 2008 study published in Mycoses revealed that ozonized sunflower oil had a success rate equal to or greater than ketoconazole cream in treating onychomycosis.
4. Snakeroot Extract (Ageratina pichinchensis)
Snakeroot extract is a natural antifungal derived from the sunflower family. It’s widely used in traditional Mexican medicine and has proven its efficacy in clinical studies.
How to use:
- Apply the extract every 3 days for the first month, then twice weekly in subsequent months.
- Continue for up to 3 months for best results.
Evidence: A 2008 study in the Journal of the American Academy of Dermatology found it to be as effective as ciclopirox, a standard antifungal lacquer.
5. Propolis Extract
Propolis is a resinous compound produced by bees. It contains flavonoids and phenolic compounds, giving it strong antifungal, antibacterial, and anti-inflammatory properties.
How to use:
- Apply propolis tincture directly to the infected nail daily.
- Let it dry before putting on socks or shoes.
Study data: According to a 2016 study in Phytotherapy Research, propolis extract inhibited fungal growth in over 75% of participants with onychomycosis.
6. Spirulina (Arthrospira maxima)
Spirulina, a nutrient-rich blue-green algae, has been shown to inhibit fungal growth thanks to its antioxidant and anti-inflammatory properties.
How to use:
- Topical spirulina-based ointments are becoming more available.
- Apply twice daily to the nail area.
Research insight: A 2022 pilot study from Mexico demonstrated spirulina’s potential in treating mild fungal infections when used topically.
7. Oregano Oil
Oregano oil contains thymol, a powerful compound with antifungal and antibacterial effects. It’s considered especially effective against Candida and Aspergillus fungi.
How to use:
- Mix 1–2 drops of oregano oil with a carrier oil like coconut oil.
- Apply directly to the nail once daily.
- Do not use undiluted oregano oil as it may burn the skin.
Caution: Discontinue use if irritation occurs.
8. Listerine Mouthwash
Though it’s meant for oral hygiene, Listerine has antiseptic ingredients such as menthol, thymol, and eucalyptol — all of which have antifungal potential.
How to use:
- Soak feet in a basin filled with Listerine (or a 50/50 mix with white vinegar) for 20–30 minutes daily.
Evidence: While clinical trials are lacking, anecdotal evidence and dermatologists report mild success in cases of early-stage toenail fungus.
9. Apple Cider Vinegar (ACV)
Apple cider vinegar’s natural acidity may help kill fungus and restore the skin’s pH balance. It also has mild antibacterial properties.
How to use:
- Mix one part ACV with two parts warm water.
- Soak feet for 15–20 minutes once a day.
- Dry thoroughly afterwards.
Pro tip: You can also dab undiluted vinegar on the nail with a cotton swab before bed.
10. Garlic
Garlic contains allicin, a sulfur-rich compound known for its strong antifungal activity.
How to use (topical):
- Crush 1–2 garlic cloves and apply the paste to the nail.
- Leave on for 30 minutes and rinse thoroughly.
- Repeat daily for 2–3 weeks.
How to use (internal):
- Consume raw garlic or take garlic supplements (after consulting with a healthcare provider).
Evidence: A 2000 study published in Antimicrobial Agents and Chemotherapy confirmed garlic extract’s antifungal potential against a broad spectrum of fungal strains.
Final Thoughts: What Works Best in 2025?
Toenail fungus treatment is not one-size-fits-all. The effectiveness of home remedies depends on the severity of the infection, consistency in application, and individual skin sensitivity. For mild to moderate cases, many of the above treatments — especially tea tree oil, Vicks VapoRub, and ozonized oils — have shown promising results.
However, for severe or persistent infections, it’s best to consult a dermatologist or podiatrist. Early diagnosis and treatment significantly increase the chances of successful outcomes.
Frequently Asked Questions
Can toenail fungus go away on its own?
In most cases, no. Fungal infections often require active treatment to resolve.
How long do home remedies take to work?
You may begin to see improvement in 4–8 weeks, but full nail regrowth can take 6–12 months.
Are these remedies safe for everyone?
Most are generally safe but can cause irritation or allergic reactions. Always test a small area first, and consult a doctor if you’re pregnant, diabetic, or immunocompromised.
