The #2 formula is a constipating formula what it is used for is to grab everything off your colon walls basically to put your poop in a group then you use #1 to help push it out. If you do a fast while on these formula you get much better results, I had 14 ft worth of black gunk come out of me but I was on a 37 day fast at the time and it bought me a great deal of health by doing that it took years of build up out of me.
To see how #2 works just put some in a cup or if you have it in capsule put it in some water and you will see how it bulks up and that is what is happening in your colon.
