Dimethylsulfoxide! Haven't thought of that in years. I remember it was really big in the early '80's, people were using it for all kinds of things. One notable effect is that when applied topically, the person would soon taste a garlic-like flavor in their mouths. I had no gut issues at the time, so I'm not sure if IBD was one of the uses. Doing a little searching, I see a 2006 study where the chemical was given in doses of 3-20 grams/day, and which seems to indicate it may be effective at reducing diarrhea and protein-losing gastroenteropathy associated with amyloidosis in Crohn's. A couple of other studies seem to show that DMSO limited chemically induced IBD in rats under a number of circumstances. A study from the late '70's showed the chemical was quite effective at relieving symptoms in a number of conditions characterized by genitourinary inflammation, and apparently, the US FDA does sanction its use in a interstitial cystitis. It's said to be pretty non-toxic, so it sounds like it's worth a shot. I'd love to know what results you have, if any, please report back.
DMSO is basically a solvent, it should be pretty cheap, and at least in the US, I don't believe it's controlled in any way. So if it's at least sometimes effective in certain disorders, it's cheap, and relatively safe, people might wonder, why isn't it used more? Simple. Big phrama prefers to produce and market compounds it can patent, and thereby maximize profits in their sale, to non-patentable chemicals like DMSO.
Again, I'd love to hear what your experiences are once you give it a try.
