That site has lots of neat information on it. I think I will try the xylitol in some form or another. I had such great results with OP and my head/sinus health that I was reminded that allergies and sinus infections are not chronic and incurable, and xylitol seems to contribute to head health, too. It is interesting how many ways its beneifts seem to overlap with oil pulling!
Not that I would put down my oil for anything, but I am going to give it a shot.
