Josiah (3 mo) has had thrush for a while now. We got the purple stuff (gentian violet) and it made a huge mess and he got sick of it after a while (seriously, he started throwing up when I put it in his mouth).
Then we got a prescription for Nystatin suspension. They must suspend it in double strength sugar syrup. I could not get over how sugar laden it was for something that is given to kill a form of yeast! Dh said, "Isn't that sort of defeating the purpose?" But we tried it anyway. It didn't get rid of it either.
So after doing some reading on safety and whatnot, I brewed some strong Pau d'arco tea, to keep in a jar in the fridge, and began swabbing his mouth (and, of course, my breasts) with it whenever it came to mind (usually right after a feeding).
It made such a difference, so fast, I was astonished. By the end of the first day I could see a major change in the amount of spots. By the middle of the next day the vast majority of the spots were gone.
I thought it was completely healed yesterday, but now I can see a few tiny little spots are left, so a day or two more of consistent treatment should do the trick.
Oh, and he doesn't mind the taste at all. I tasted it myself and it tastes mostly like water with just a bit of an "earthy" flavor. He's not so keen on the cotton swab being stuck into his mouth and rubbed around, but he's not making that "Yuck!! Mom! What is THAT!" face like he did with the other things we tried.
Thought I'd share.
