Hemorrhoids r pretty much the same as varicose veins at the legs. I dont see how Iodine would cause that.
Also .... how r ur enemas that clear that u d see if any Iodine has been absorbed.??? How much do u fill in? How long do u let it in? how often?
I cant imagine that anyones colon (except u do it daily or evwn more) is that clean that water comes out clean.
I personally only do it at WE and fill all 3 colon parts (dont know the names in english) with 2 liter water and its never clear water. Ok obviously i use coffee but still i can see (sorry for details) see brown fecal stuff.
I doubt it would ever be clear in my case even with only water.
