THis is what Dr. Schlutz says:

"This stimulating tonic is both cleansing, healing and strengthening to the entire gastro-intestinal system. It stimulates your peristaltic action ( the muscular movement of the colon ) and over time strengthens the muscles of the large intestine, halts putrefaction and disinfects, soothes and heals the mucous membrane lining of your entire digestive tract. "

"This formula can be taken for a week, a month or the rest of your life"
It seems safe to me. Just concerned about whar u said, since I'm taking it now.
