I just started using apple cider vinegar. I am on a bunch of pro biotics and nystatin but I think the vinegar is helping in my mouth.
I used to rinse with peroxide but I think it was killing the good bacteria too. Maybe I made it too strong.
You need to get unprocessed APV with the "mother" which are the little fragments floating around. I use the "Braggs" brand and you can get this at wal mart.
I mix 1 tblsn with 1 tpsn raw honey and 1/4 tspn of cinnomin in a little warm water and sip this each morning. I beleive that the vinegar is supposed to help alkalize your body too. Mine is very acidic these days, so every little bit helps!
by the way, i do notice mild herxing from candida die off but it's all good. The more bad bugs dying, the better!
Good luck, I know oral thrush can be painful and we need our mouth for so many daily functions ;(
