LL- you are correct about the different types of biofilm, there is great variability. I know that frequency can help however as I had good success combining JMT treetments with the BPA frq to clear the clonorchis biofilm a few months back. it worked quickly and well. Re alkalinization, I tried that ahwile back, but concluded that it doesn't work as advertised. the alkaline diet helps because it contains so many healthy foods. messing with ph, however, can backfire, esp with things like candia. acid in the gi track is actually one of the things that keeps it in check.
