I have tried it and I think it is very valuable. But don't put too much Iodine in the enema water or it will give you a hemorrhoid on the way back out. I made a batch of enema water that was dark orange with iodine. Apparently my body was grabbing up the Iodine out of the water because the water coming out was not as orange as the water going in. It was rather surprising to me and I am stilling wondering how it happened.
