Got a fungal infection on my big toe about 4 months ago, had never had one before. OTC treatments were very expensive so started using cider vinegar. Didn't seem to have much effect and smelled terrible. Most of the nail came away at one point, it was yellow/white and loose. Switched to tea tree oil, and it's deifnitely causing an improvement.
I apply a few drops twice a day directly on the nail. There is still some yellow and white on the nail that's left but new pink healthy-looking nail is coming up underneath. I'll continue to use the tea tree oil until it all grows out. I've had no side effects so far but the oil is strong and may not be suitable for all skins. If you're sensitive to it you could dilute with a base oil, or put some of the oil in a foot bath instead. I'm also using a silver colloidal spray in my shoes as I've heard this is anti-fungal and antiseptic.
Tea Tree Oil
I've been fighting a fungus between my little toe for years. I've spent a fortune on all the over the counter creams and also my doctor has prescribed a few things, to no avail. I read somewhere about 2 months ago to use Tea Tree oil. I've been applying the oil for 6 weeks now and have had no itching since the first application and the fungus has cleared up remarkedly. There is still remnants of scarring and discolorization in the area and I really think the fungus is still there but I'm going to continue this treatment. Any suggestions as to what else to do would be appreciated.
