Doctors don't believe in candida, that's why they don't promote the diet, probiotics, etc. Did you know that Antibiotic tablets used to be coated in Nystatin to prevent these infections? I heard that a while back and found it amazing. Boy you sure won't find any made in that way now.
I'm sorry your friend is also suffereing :-(. Yeah, it's odd how many people I have come across that seem to have many of the same health problems I do, and when you ask them if they've had any rounds of Antibiotics , they have.
