If you ask Colonix and Oxypowder they won't say there is because thereis no official medical term.
People here on the forums say they have seen it. But you never hear that they have lost 20 lbs or so.
I have used Oxypowder that is a 7 day cleanse and like it, but you don't see anything because everything gets liquefied. People that see things have often used fiber and bentonite.
