[YEA] Probiotics for Mouth Ulcers: This is so painful at first, if you're dealing with a large ulcer, but it works everytime. Open up your probiotic capsule(s) 1 or 2 is good, pour onto a dish, add only a few drops of water at a time to form a kind of paste, then, using clean hands, use your index finger to scoup up some of the paste and push it up into the sore. Try and keep from swallowing for a bit (you'll get a little drooly) between 2 and 5 minutes is good, but the longer the better I suppose. You want to do this 3 or 4 times/day.... but I've never had to do it for more then a day, once I had one about the size of a quarter on the roof of my mouth and that was nearly gone after the second treatment! It does hurt terribly bad, but only while your pushing the probiotics into the wound.
