I have had toe nail fungus on one toe nail and it kept coming back every few years after healing.

I have tried other remedies, but Iodine drops was the quickest cure, one month cure. I used Nascent Iodine, it is discolored. I'm from Europe and found it at piping rock shop in United States and purchased it there (I'm not affiliated to this merchant).

First cut the toe nail completely up to the root of the nail. Then use a scrubbing pad, kitchen type for example, and scrub any fungus or dead skin on the toe. Then apply one drop of nascent iodine. Let it there for a few seconds, them apply some coconut oil on the toe.

From then on, every day after shower, scrub again, apply iodine drop and after drying, apply some coconut oil. Avoid too much sugar when healing. Good luck with healing toenail fungus.

Better But With Side Effects

I suggest you guys use the "Colorless Iodine". Further, watch out for the "100% Natural Iodine", and "Lugol's Iodine", too, because the latter two will stain your nails. Further, watch out for fungus-infected big toenails, too, because if your nails gets stained, they will remain stained for many years to come, because the nail growth rate of fungus-infected big toenails is so slow that it is unbelievable.

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!

I also used iodine and it was very successful in curing the toe nail fungus. Every morning and night for about 4 months.

The first time I experienced toenail fungus, years ago, I tried tea tree oil without success. I eventually saw a doctor who prescribed Lamisil pills for 24 weeks. That worked. The second time I had a fungus infected toenail, over 10 years later, I applied iodine. A single drop in the morning. Probably another at bedtime (I don't recall now). Iodine worked brilliantly! Without risking liver damage (i.e., Lamisil).

My wife and I found that taking Lugols orally has resulted in clearing up both of our toe nail fungus problems. We try to take at least 5 mg /day.

Hello all, Many years ago, I went to Hawaii. I walked on the beach barefoot, it was fun. I am unsure if this was the cause but, I came back home, and one toe nail started to get thick and brittle a few months later. It got so thick, toe nail clippers won't go over it to cut it, so I have to hack away at it to get it cut. The others have been totally unaffected.

One day, I decided to cut it, but then went outside and sanded it down to a slightly less-than-normal thickness out of frustration. I noticed that the outside looked normal-ish, but inside it was pithy, like old dead wood, small hollow pockets with brown streaks.

So, I mixed up some iodine I had, some hydrogen peroxide, and some 500 ppm colloidial silver. It was 60% iodine, 20% hydrogen peroxide, 20% colloidial silver. I would paint it on in the morning a few times so that it soaked in nicely, then put on a bandage over the nail or a "finger cot" (like a condom for your finger), then take it off in a few hours. Then, when I got home, I would paint it on several times again, but let it air dry.

The nail started to grow back normally from the base of it, but I moved and was unable to continue to the current living arrangement for a year. It reverted back to the old thick nail by the end.

I am now able to continue my earlier treatments, but didnt figure that you would want to wait a year or two to find out how it goes. It takes about a year for a nail ripped off to grow completely back in (dont ask me how I know ;), so if you do this, I would continue for 2 years to make sure that it was completely gone, then a periodic treatment, once a week or twice a month or so, to make sure that it doesnt come back. If it is thick, even possibly not, make sure to sand it down quite a bit, so that it can absorb down into the nail bed better, since nails arent the most porous of substances. The key is to get it into the nail, as if you put it on and then put on socks that absorb the liquid, it wont go into the nail. That is why I used something to keep the solution from drying out and not soaking in.

Hi, haven't been here for awhile but really want to share my new success story of battling toenail fungus. I have fungus on both feet, especially bad for the big toes. I believe I got that from a damaged toenail. Have tried everything non-precription for the last 6 years - alcohol, bleach, soaking in apple cider vineger, hydrogen peroxide etc. but to no avail. In July 2011 I tried decolourized iodine. I had a hard time finding it, but finally found it in CVS when I was in Chicago. I stocked up a few. I wipe all my toenails with a cotton pad soak with that, once morning and once at night, and put Vicks on it afterwards. That's all. The bad nails are shedding and showing new nails.

Finally, after so many years I see the light of getting new healthy nails. I will continue this routine for a few more months until the new nails are all strong and healthy. I should be able to wear sandles next summer. Using Vicks is important because without it my nails have these white spots, brittle and weak. I believe iodine is quite harsh for nails and strips them dry. Good luck. :)

I cured (and am still curing) toe and finger nail fugus using decolorized (white/clear) iodine. In combination with simply eating a banana and active yogurt (yogurt that promotes digestive health), I apply the ioding every day to my affected big toe nails, left thumbnail and right ring fingernail. I acquired nail fungus in my left big toe a year ago from a bad ingrown nail. I had a partial nail avulsion to remedy the ingrown nail and then later developed a fungus when the cauterizing had healed. I couldn't afford prescriptions at the time so I started using home remedies such as vinegar gel, over the counter topical lacquers,vapo rub and mouthwash. Everything under the sun. Then I saw this website about 6 months ago. Until I read about decolorized iodine, the fungus in that left big toe had only stabilized using other remedies. Which was good-but I wanted it gone! During that time of trying everything else, it spread to my right big toe and then my left thumbnail. This was all probably because I was not careful in cleaning in treating and spread it due to my own carelessness. Anyhow, I lost those other two nails then it started in my right ring finger. I was determined at that point to find my cure. I started using the iodine on my right ring finger and it stopped the fungus dead in it's tracks! My nail has since grown half in and healthy and is still going. As for where the fungus first started, in my left big toe-that's almost completely grown in and healthy! My right big toe and left thumbnail are well on there way, but taking a bit longer to grow in. Either way, iodine (2-3 drops) 1 or twice a day, a banana and a live active yogurt overy day have been my cure. Promoting digestive health, providing potatssium to help nails grow quicker and healthier and iodine to kill the fungus topically ahve been my miracle workers. The only down side to iodine is that it can be somewhat drying so I suggest using cuticle oil in between treatments. Do not use peroxide in combination with decolorized iodine. It will turn your skin orange! I only used alcohol to clean the affected areas before applying iodine and to sterilize the instruments I am using as well. What really sucks abou this whole thing, is I developed dyshidrosis as a secondary skin disorder from the fungus. That's a whole other story, but dishydrosis is like eczema in a way and it will resolve on it's own once the fungus is completely out of my nails and body.

I purchased decolorized iodine. It is clear out of the bottle but when it comes in contact with the skin it turns orange red immediately. It doesn't wash off and stays that way for days or weeks. I find that strange since the red colored iodine washes off very easily. Using it with Peroxide soaks and my skin around the nail is very dry and cracking and a little red. I'm going to keep using peroxide and not sure what else. There are so many ideas and opinions. In six weeks I have a trip to a lake resort area. Ikes!!!!!!!!!

EC: Not the colorless brand of iodine we use! It stays clear on the skin unless we've used peroxide first, in which case it does dye the skin orange for a while...

I have recommended white or clear iodine for 23 years for the treatment of nail fungus. Iodine increases nail growth while treating the fungus at the same time. Adding a few drops of vitamin e along with the iodine to the underside of the nail is helpful in keeping the area from becoming too dry. Iodine can be used on healthy nails to increase growth. In that case I wouldn't apply more than once a week.Until recently colorless iodine was hard to find in Michigan. There are expensive over the counter treatments for nail fungus which usually don't work.If purchasing these check the label to see if iodine is an ingredient.prescriptions for nail fungus,(lamisil) can be damaging to the liver and it's very expensive, often not covered by insurance. It usually takes 6 months and lots of blood work to have a healthy nail back. Try the iodine first! marilyn-the digithelper-manicurist

Iodine Tincture (2.3% solution cured 'Toenail Fungus. I whacked my infected toenails using a large hammer. In about two weeks the nails fell off and I applied iodine. When my new nails grew back, I had no more fungus.

Iodine is excellent for toenail fungus, ringworm, fever blisters, moles and skin tags, hangnails, etc. Just a few drops on a q-tip is all it takes. Use daily until the "boo-boo" is gone.
