Green Stools

Green stools is either bile discharge, (like when you do a liver cleanse or when you take loads of carrot juice or apple juice for liver treatment) , or else it witnesses the presence of oxygen in the chemical reaction (good sign). Your case seems to be the latter. I've had such green stool prior to passing mucoid plaque - your intestine seems to be getting rid of the top layer of its crust!

Ciaoooooo!
