After some review, I do not endorse the average cleansing product that are primarily sold in health food stores.
Why? Because many if not all of these products are a bit harsh on the stomach (in my opinion).
My version of a cleanse is: EAT MORE FRUITS, VEGETABLES and drink LOTS of WATER.
Here are a few links with a list of foods high in fiber...yes..fiber...as this will definitely cleanse the digestive system in a natural manner.
Cleanse: Increase Fiber and water intake!
