The cleanse will give your body time to start healing itself. Your digestive system will be given the rest its probably been begging for via the diarrhea. The cleanse will help you lose mucous, waste and other matter.
Try it and see if its for you. If not, use it as a stepping stone to research this site for wonderful information to improve your health. The first time I failed, but I kept searching and improving. And, now I'm doing the cleanse again.
