Neti pots! I've been using one every day for about two weeks, and now that I've perfected the process, I do it twice a day. It's a fantastic natural remedy.
As for toenail fungus treatment, I've heard of Vick's, neem oil, and tea tree oil. What seems to work best for me, although I haven't been doing it for long enough to know for sure, is simply to file off the affected part of the nail and then clean it with plenty of Listerine. When filing, I hold the file almost parallel with the nail, but with a slight downwards angle, to give the end of the nail a bevel. Filing in that fashion makes it easy to shorten the nail without allowing the deeper part of the nail to pull up from the toe.
