This is an old thread but Lugols' wont cause C - diff but in my case (after four months of that nightmare and 4k in traditional and not traditional docs) I found an R.N. and a solution which worked not only fast but completely. I already knew about Hanna Kruger.
Tumeric and Lugol'sIodine enema's. (I was familiar with Lugol's from the Max Gerson M.D. Therapy (friends grandmother with Cancer long ago).
I have a background in both legal and medical research (mother an R.N. but I opted for natural therapies for most situations since an early age).
