Laxatives won't take plaque off the walls, it's stuck on their like cement, which is why it's so hard to get it loose.

Those colons that are cleaned out for colonoscopy are free of waste inside the colon, but the walls still have the plaque on them. It adheres so closely to the wall that it's mistaken for being part of the mucosa (wall covering). Richard Anderson explains this in his book Cleanse and Purify Yourself, how during colonoscopy, colons that are free from plaque show the tiny blood vessels clearly on the surface. Whereas colons covered in plaque initially look the same, but there's a difference, the blood vessels almost can't be seen, they are covered over.

It's not a black tarry covering that people report when the stuff is removed...I guess while it's still in the body, it just adheres closely to the wall, but looks like the wall...except for it masking the blood vessels.

I still don't know why when it's removed it becomes black tar...in a sense I can imagine that when in the body it's still kept alive, but once loosened, it's dead...and dead things sort of rot. I really don't know though, just some thoughts. Plaque can also be different colors, so I've read, from black, to dark brown, to beige even, and the oldest layers being the most toxic and foul...but I have seen photos of colons with and without plaque and there's a difference. Many MD's don't know of plaque and if they do, I think most don't subscribe to the theory, so gastroenterologists wouldn't be making such distinctions with colonoscopy.

I tend to believe it's a real entity, mainly because of the way people get well once it's removed, and also because people have removed it when NOT taking psyllium...that is, it's not just a psyllium artifact.
