If you develop an ingrown toenail you might try putting a drop of mineral oil or Atomidine available from the Heritage Store on the area once or twice a day. A link to the store can be found here. Many times it will correct itself and grow out. Much depends upon your nature and the extent of the condition. You may have a few tender days as the nail moves out pressing against the skin. I like the Atomidine because the iodine tends to numb the area plus prevent infections but the mineral oil also works. Obviously, if this does not solve it seek medical attention.
The Atomidine may also work with a nail fungus. In which case I would apply it twice a day for a week or more then as needed letting it soak in before covering it with anything. Years ago I read where Atomidine had been tested in dirty water and within an hour all the bacteria and other harmful life forms had died. I believe it was 1 drop per gallon and wait 1 hour before testing. However, I doubt the study had scientific merit and I did not give it much thought because if you use it to purify water you would very likely be taking in too much iodine. You could use it in an emergency situation but not as an everyday practice.
