Colon Cleansing to Remove Mucoid Plaque

What is a colon? Why is a cleanse colon procedure necessary?

The colon is the part of the large intestine between the cecum and the rectum; it extracts moisture from food residues before they are excreted.  From Wikipedia, it is the last part of the digestive system in most vertebrates ; it extracts water and salt from solid wastes before they are eliminated from the body, and is the site in which flora-aided (largely bacteria) fermentation of unabsorbed material occurs. Unlike the small intestine, the colon does not play a major role in absorption of foods and nutrients. However, the colon does absorb water, potassium and some fat soluble vitamins.

Experts say that colon cleansing is very important to remove the mucoid plaque from the colon.  One can start by fasting and then a procedure involving supplements.
