Just saw an advertisement for a pharmaceutical for Crohn's disease, which reminded me that I also just read that colloidal silver has helped many people with Crohn's. I'm not sure I am spelling this right, I just know that there is an "h" in there somewhere. The article was from the Silver Edge website, but I use the product and have knocked out food poisoning with it, and it is good for so many things, I don't doubt it's effectiveness for Crohn's. The article didn't say that it helped everybody and it is not a cure, but there is no problem with long term use, so if it works, great.
