About ten years ago, I had a nail fungus that had existed for about three years. I tried a number of the over the counter solutions and none of them worked. I talked to the pharmacist and keep in mind this was ten years ago and I don't know what's available now. At that time, the pharmacist said that there were pills but that they were only marginally effective, if at all, and there was considerable risk in taking these pills.

So, I started considering other ways I might get medication below the nail to treat it. At one point I even considered drilling a hole through the nail to try and introduce some kind of medication.

Then, having made wine for years, I was aware that if the primary fer-mentor became too warm/hot that the yeast would die in what's called a 'struck' fermentation. When that happens the must needs to be cooled down and new yeast needs to be introduced, to restart the fermentation.

I wondered, if heat can kill yeast, perhaps it could also kill fungus. So, here's what I did.


I took a piece of congregated cardboard about six inches square and made a hole about a half inch in diameter in the centre. For those using metric, this would be about 15 cm and the hole would be about 1.3 cm. If you are treating multiple nails you should consider making multiple templates with different size centre holes commensurate with the size of the nail to be treated. The hole should always be smaller than the size of the nail being treated. The purpose of the cardboard is to protect the skin surrounding the nail, so that only the nail receives the treatment. One further thing I needed was a handheld electric hairdryer.

Treatment: So, each morning after I had my shower, I would hold the cardboard over the nail that needed treatment, and direct the heat of the hair dryer through to hole in the cardboard to treat the nail underneath until I felt a minor pinch. I would then wait about twenty seconds or so for it to cool down, and then do this two more times. I originally intended to do this for seven days, but in the end, just to be sure, I did this for a total of ten days.

I then just allowed the nail to grow out. The nail grew back and there was no more fungus. That was ten years ago and the fungus has not returned.

I hope this is of help to anyone out there that's needing this solution.



Lemongrass Essential Oil

I used lemongrass oil after beginning a probiotic a month earlier. The lemongrass oil killed the fungus and infected nails. I used it until it irritated the surrounding skin. Two months after taking the probiotics I can see new healthy nail growth at the cuticle, the old dead nails are like scabs. I expect the combination is the answer as I had an appendectomy in 1970 and the fungal symptoms started in the mid 1990's.

Update to my original post:

The nails cleared up. I persisted in using Vit. E oil for two years, once a day, then stopped. The fungus has NEVER returned!

Hey Sarah,

did you ever find something that helped?

Posted by Dave (Virginia) on 07/25/2021

The easiest way to alkalize is to use baking soda 1 teaspoon in a large glass of water once a day for 2-5 times a week depending on ur situation. Baking soda alkalizes you and helps to clear up all kinds of things in your body. We are way too acidic from the food we eat. This causes many physical problems. Don't buy expensive alkalized water. Baking soda is cheap and it is used in many foods . It is harmless unless like anything else u use way too much too much of anything is not good. GOD BLESS ALL WHO READ THIS.

Hydrogen Peroxide

I recently began treatment with hydrogen peroxide after having lived with chronic toenail fungus for over 20 years. I used 6% H202 to soak my feet for 20 minutes each night for a month. As the fungus was killed off the damaged part of the nail softened and peeled off painlessly. I switched to borax soaks, and the nails are thinner and clearing. I still soak on alternate days and apply Kerasal and now the nails are normal except for the length in only 2 months!

I am also based in Vancouver and have been struggling with nail fungus. How are your nails doing in 2020? Did you ever manage to find colourless iodine here in Vancouver? What has helped you most?? I appreciate your help. I'm in desperate need of it.

White Vinegar

I cannot stand the smell of ACV, plain old white vinegar works just as well, I would spray it on the 3 toes 2x a day, waited til the entire toenail bed grew out, no more toenail fungus, rah! Just put the white vinegar in a glass bottle so no plastic uglies leach into the vinegar. It really, really works!!

I pour a little rubbing alcohol, the cheap stuff you buy for a dollar a bottle also called isopropenal, on my toe nails after I shower. It works well for me. The alcohol soakes into the nail and the fungus.

I tried many remedies, for my nail fungus (both thumbs and an index finger) but what actually worked was filing down the nails with fungus (about once a week) and then putting a layer of decolorized iodine on my nails followed by a bit of petroleum jelly to moisturize.

I did this every night before bed until the nails grew out a beautiful pink color. I'm so happy to get my nails back! And this remedy is do cheap!

Castor Oil

I hurt my foot and as a last resort applied Edgar Cayces castor oil remedy. I put castor oil on flannel enough to cause the flannel to be wet but not dripping. I then wrapped my foot. Had left it on for 3 or 4 days when I needed to go to my acupuncture appointment. As he was applying the needles he exclaimed my toe fungus was gone. All except one small spot. I then asked my Dr if my toe fungus was gone a week later and he also said one small spot. My toe nails are beautiful white and healthy looking. I now have done both feet. I am still wearing the castor oil for the pain in my foot. I did use organic castor oil. And I am lucky enough to be able to wear the castor oil about 20 hours a day.

Distilled Vinegar
Posted by Fleur (Australia) on 10/28/2020

I'm a bit confused about which vinegar to use. In Australia our vinegar in grocery stores doesn't say if it's distilled or not. When I googled it, it seems like distilled vinegar is weaker than white vinegar. And distilled is suitable for cooking, because it has been purified.

In the above quote, he talks as if distilled vinegar is cheaper than regular white vinegar. But here, vinegar suitable for cooking (which I assume is the distilled version) is more expensive than regular white vinegar...

DIY Hand Sanitizer
Posted by Redj (Cuba) on 07/23/2020

An update:

I have switched my application method to using a finger cot (cut a finger off a disposable glove to achieve the same thing) and a piece of cotton wool soaked in 0.1% Benzalkonium Chloride.

I apply the soaked cotton wool to my infected toenail, put the cot over my toe, and leave it for somewhere between 1-4 hours depending on what I'm doing and how forgetful I am on the day. (Even 1 hour is probably overkill if I'm being completely honest.)

This works really well to get the solution to soak right through the nail, I have been having good success with only one application a day, and the only caveat is this:

I no longer use crushed aspirin because that caused some minor irritation to my nail bed but it's unnecessary anyway as I am definitely getting a thorough application penetrating right through my nail this way. (Likewise, there is no need for soap as the solution has nowhere to run off to.)

I would recommend this new application method wholeheartedly.

I reuse the cotton wool and the finger cot until they look bad, then I replace them. I have little concern about reinfecting my nail by doing this because both get absolutely soaked in the solution which kills the fungus so I don't see it being a problem however if you are not seeing progress you should switch over to a strip of tissue folded up appropriately before soaking and applying and then disposing of it after each application, and likewise for the finger cot. (This is where cutting a finger off a disposable glove would be ideal because you will get 5 day's application from a single glove so it will be quite economical this way.)

ACV, Borax and Peroxide Soak
Posted by Julie (New Jersey) on 06/23/2020

Bill, regarding you and your girlfriend having issues with the air conditioner.

I found when I first moved to my apartment that if I'd been using the A/C, then there was maybe a week or two where it was cool enough to not use it, when I'd return to it I got massive headaches. I could barely detect a smell in the air that is only there when the A/C is running. I inspected it to find that when I took off the front cover, a (nonremovable) tray at the bottom of the unit collects an inch or so of water.

To make a long story short, it was growing mold, even if the tray had time to dry before I turned it on again. My solution was to purchase bottles of colloidal silver online that are intended for treating hot tub water in place of chlorine or bromine. I only have to put in maybe a dropper full, and this purifies that tray so that the when the A/C is on again, it's not filling my apartment with mold spores.

DIY Hand Sanitizer

This cure is based on a scientific study with good results (DOI: 10.7547/87507315-89-3-124) and made into DIY home remedy.

The study used a solution of 0.1% Benzalkonium chloride which is a common ingredient in non-alcohol based hand sanitizer. At 0.1% there is no risk of skin irritation unless you are allergic.

The other ingredient was allantoin which is a mild keratolytic and surfactant. This can be replaced with a crushed up aspirin (acetylsalicylic acid), dissolved in approximately 100ml of solution. Mild body soap may also be added in a small amount however this isn't necessary but it may help.

The study applied the treatment to the infected nail and the base of the nail twice daily over 10 months.


• Benzalkonium chloride 0.1% (Non-alcohol based hand sanitizer or a concentrate diluted appropriately)

• 1 crushed aspirin, dissolved in 100ml of solution (optional, dilute further or omit if you experience a skin reaction)

• A small amount of gentle soap or bodywash (optional, omit if you experience a skin reaction)


Cut away all excess infected nail with separate nail scissors or clippers so that you don't spread the infection to other nails.

Using a separate file, file back the nail on all surfaces well often. Ideally this should be repeated at least twice a week or more for best results.

Apply solution to infected nails once in the morning and once in the evening, ensuring that you cover underneath the nail where possible and where the base of the nail joins your finger or toe. Ensure that you apply the solution after showering and drying yourself for best results.

Continue until the infected nail has been removed and only uninfected nail remains.


This is a safe method of long-term treatment of nail fungus which has good results in controlled study environments.

Hand sanitizer can be applied regularly to the skin and left to dry and has very low risk of causing irritation.

I have personally been applying this solution regularly for about a month and a half and I can see a clear diagonal line of new, uninfected nail emerging from the base of my infected toe. I have often applied the solution more often than twice a day with no ill effects.

If you are a busy person or you have a disability which makes this sort of treatment regime difficult you can try applying the solution to a cotton ball or similar and attaching this to your infected nail using tape or a band-aid. The benefit of this is that you can re-wet the bandage for reapplication of the treatment, and as the solution remains in contact with the infected nail for a longer period this should result in a higher success rate. Ensure that you pay close attention to ensure that you are not causing irritation with the prolonged skin contact from this method.

Castor oil is so easy to use and works better than anything I have ever used. Just apply it to your toenails and toes. It penetrates the skin and the nails.

Castor Oil is the best thing to cure nail fungus. I've tried so many other cures and none of them worked. Castor Oil penetrates deep into the skin and is useful for skin problems, such as cysts. It's amazing to see all the useful problems it can be used for. It's oily but it cures.

Apple Cider Vinegar, Tea Tree Oil

Toe Nail Fungus. Tried many things for five years with no results, my big toenails were almost completely black. Soaked a cotton pad in ACV and taped it on to the toes and left it on for a few hours. Before bed I soaked the toenails in tea tree oil. After two weeks the black has all gone and the toenils are starting to look normal again after five years, amazing.

If Nothing helps toenail fungus, try:

Fold down 2 napkins just to cover your toenails and toes completely, then pour with 3% H2O2, wrapped with a polyethylene(cellophane, etc soft film), needs good plaster to fix on feet all the night and wash your feet in the mornings with laundry soap. Needs 10-14 days. Hope you get rid of fungus forever.

Don't forget to change all your socks, sandals&shoes/ or at least pour shoes with ACV every time.

Thank me later.

Yes, I too used iodine for curing toenail fungus infection. And it worked so brilliantly that my fungus infection got vanished just after three weeks.

Posted by Ninette (Cincinnati) on 06/10/2018

I found Iodine ( not clear) its true brown color at a pharmacy in Tampa FL. DAVID PHARMACY.

My grandmother in Cuba used iodine to cure much. Health issues. Is a great Desinfectant. ..

Castor Oil

A long dark winter in heavy socks and vinyl boots gave me a case of toenail fungus.

I was reading through the remedies here, and something that occurred to me was that fungus needs three things in order to flourish: moisture, darkness and oxygen. I figured if I can remove two of those conditions then I would be all set.

Night before last I slathered my toe in castor oil, wrapped it in a bandage, and went to bed. I felt tingling under the nail early in the morning, and then when I looked at it, the patch of discoloration and inflammation had reduced by about 30% in area.

I put on sandals, hit the area with 415nm blue light (acne pen) for about 12 minutes, then applied more castor oil. Went around barefoot all day, with castor oil all over the toe. I went to bed last night with another plaster and woke up this AM with about 50% reduction in area and discoloration of the nail.

Castor oil appears to work very well in starving the fungus of oxygen because it is very sticky and viscous, but also it gets into all the crevices where the fungus might retreat to in order to seek an oxygen source.

Fungus is very clever and very patient. If it detects that conditions aren't ideal for it to flourish, it will retreat into spore form and wait for conditions to improve. Spores can survive for years, which is why you have to keep on with a course of treatment for a long time, and why the infection can crop up again.

This is also why blue light exposure can help because it interrupts the sequencing of the DNA of the organism.

So far so good. If I hit a snag I will report back, but for now it looks like this thing is on the run.

I've suffered with it for years ive tried over the counter ointments from pharmacy none are that effective it takes for ever to get an improvement. I tried Oregano and Clove Oil Essential Oils they both kill fungal and viral bacteria. I also added Carrot Seed Essential Oil to encourage the skin to heal and reatach to new growth on toe nail. I used Coconut Oil as a carrier oil. I cut the nail right back to take away the home for fungus (I know you are meant to leave it at it can cause in growing toe nail in new growth).

I had instant relief from pain in my nails cause new growth happened rapidly. Now 3 months on, I have healthy pink toe nails and I'm not embarrassed to get out in public. New toe nail growth has attached to my toe for the first time in 10 years.
