I was told by another provider that she swares on "burnt flower" she even keeps a salt shaker full of it in her diaper bag. You litterally burn (brown) flower in a sauce pan, cool it off and apply some to diaper rashes......all gone by next diaper change if not the next day depending on how bad it was.

My daughter recently became a super pooper but I'm sure it's the mix of meds she's on - nothing prescription though....tylenol, advil, fake tears, eye drops, eye ointment etc.
