Put her on high strenght garlic and grapefruit seed extract for 2 weeks, no probiotics, then stop that and go on high strenght probiotics with biffidum bacteria in it as well as acidolphillus.
I am a medical herbalist, nutritionist and this is a very good way to elimate yeast, its worked well for my son. He now has no yeast issues and can east sugar etc. As for stoppn staraches I tried this and my son lost soooooo much weight. Your call.
hope this helps
