What about the vitamin c and salt flushes? I was reading about that yesterday on a lyme disease website (lymephotos.com) and they say it helps to shed all the yuck in there.
I haven't tried it yet.. but it's something I want to do eventually.
I like MSM too.. i could tell that it changed the quality of my lung mucus, but can't tell about intestinal. I don't think it cleans it though...
