you have to read this book or at least find it in borders and look at the section on crohns disease and treatment with intestinal worms

they genetically engineered intestinal worms to not breed so they died about about six to eight weeks and patients drank them in larva form which are microscopic and just having them in the intestines for that length of time virtually cured most of the crohns patients.

they thought they would have trouble getting volunteers but the patients were standing in line all with really bad crohns facing surgical removal of their intestines

really great read also written by female evolutionary biologist

Have you worked with hypnosis at all (or similar mental focusing techniques)?

As a fellow crohn's sufferer, I might recommend the following:

DHEA, 200mg a day. At least one clinical trial has shown this to put crohn's into remission. I found good results with as little as 100mg.

Saccharomyces Boulardii - this is a probiotic that has been demonstrated to help with crohn's. You can go the expensive route and buy the Jarrow's or other health food store brand, or get just as good with "Digestive Advantage Crohn's and Colitis Formula" (sometimes packages as "Colon Care"), which you can buy in most chain drug stores. I will testify to its positive effect, tho you might have to start with double the dose if you are having a flare up.

Aloe juice, 1 glass after meals. Soothes the innards.

Hypnosis, as Dan mentioned, can be very helpful. Michael Ellner in New York City specializes in treating IBS and UC with hypnosis.

And, since this is a psychonaut's tribe, I will recommend psychedelic therapy. When I was a teenager, crohn's was a real problem for me. My doc was prescribing paregoric and it only partly helped (a stronger opiate might have done better). I was having a particularly acute attack on the evening my friends and I had scheduled for our first LSD trip, which I didn't want to miss. At first the acid increased the intestinal pain and gas... and then it faded out and I forget about it. AND THE DISEASE WENT INTO REMISSION FOR 20 OVER YEARS. It didn't resurface until I had to take a massive course of antibiotics for Lyme disease and trashed my intestines.
