Try liquid Silver.
I have customers who have IBS and they use a product called Lily of the Desert's Stomach Formula. It's excellent. You can add one or two drops of collodial silver to it too, but it already has a lot of good stuff in there. All of my customers are people already under medical care. One was going to have surgery but opted to go to a wheatgrass retreat instead, and lives off mostly juices and distilled water.
