The advice on the minimal bleeding is sound. Some periodic bleeding is common in Crihn's; it's the steady, heavy bleeding that needs prompt evaluation.
On the autoimmune front, there's been debate about that for years. Most folks (including doctors who treat it) believe that Crohn's is a runaway immune response to one or more stimuli (bacteria in the gut?) that is probably made more likely by a genetic susceptibility. So in that sense it is autoimmune, though not by the strictest definition. The bottom line is that debating cause is futile once you have it; the task then is to treat it most effectively so as to minimize symptoms and damage over time.
On the natural remedy front, there are some probiotics and other supplements that seem to help some people, but I for one believe it is a mistake to try to treat Crohn's largely or exclusively with dietary supplements and other "natural" remedies. medical therapy for Crohn's is so individual for every patient, there's no "one size fits all" prescription.
I also want to add a word of caution about the SCD. It has caused severe and life threating bleeding as well. Plus there is no such thing as "healing" or "curing" crohns. The appropriate statement (and this is also one check for legitimacy) is that it has caused remission.
