Psyllium husk fibre and apple pectin are used for their bulking and cleansing properties for the bowel. Psyllium husks will 'bulk up' and scavenge along the intestinal tract, removing built up debris, old fecal matter and even diverticuli pockets. Charcoal also acts like a sponge, helping to remove toxins from the intestinal tract. Also contains Magnesium, Vitamin C and Apple Pectin.
