[YEA] I shoved a wood splinter under my finger nail and ended up with a fungus under the nail. After finding this web site, I started the peroxide/white vinegar/ tea oil treatment. I cut the old finger nail way nearly down to the cuticle; soaked my finger in hydrogen peroxide, then white vinegar and then applied tea tree oil/vaseline (50-50%). I did this for about 3 months and then went to just soaking with white vinegar morning and evening. This worked and the finger nail is well and nearly grown out completely and looks great. It takes time for this cure to work, but it sure does work!!
