We also have a fellow member at raw paleo forum named Ionna and she also cured her IBS by going on a raw meat diet.
You might find it easier to interview her.
The secret in both success stories was bacterial filled raw meat. One above even makes high meat for even more bacteria.
It is the absence of proper flora and the indigestibility of cooked matter in some people that is harmful and causes IBS. I highly doubt colloidal silver is the answer, I would throw away stuff that eliminates bacteria. We need to encourage good bacteria.
