What you're looking at in these pictures is the colonic supplement itself after mingling with the natural mucus and chemicals in the intestines. The colonic products that produce "results" invariably contain some kind of indigestible solid, typically clay. It comes out the other end looking like this.
It is a LIE that you have undigested food or other remnants inside you that hang around for years. Unless there is some other actual medical condition that affects the enteric system (such as Crohn's disease), the colon is clean and pink and the only thing you'll find in there is normal poo that comes out on a regular basis.
These "colon cleansing" products are snake oil at best, actually harmful at worst. They are a scam, plain and simple.
Thank you! I did watch a program about what a new age scam this was!
