I'll start by saying IBD is known to be a "first world disease", so it's almost certain that a difference in lifestyle, diet, or something else in more developed countries is to blame. What that is exactly no one knows. I personally have a suspicion it's overuse of antibiotics. That said, I hope I don't come across as combative, this is a very touchy subject for me and through the course of dealing with this I've come to live by two maxims 1. If it sounds too good to be true, it probably is. 2. Alternative medicine that works is just called medicine. Everybody poops, and it seems everyone has an opinion on it. With IBD being an incurable and very frustrating disease to treat, I've found there's a huge market for diets (for which you need to buy the book to get the full story), herbal supplements (which need to be purchased and used for months before any effects can be felt) or any other sort of miracle cure. Have I tried that specific type of supplement? No, but I've tried many like it. Most will all claim the same things, I'd likely be dead by I got around to trying them all. Everyone wants an easy, cheap, and healthy cure with no side effects, but it's just not there. Most people will have some form of minor digestive issue in their life, the placebo effect is strong, and I believe a lot of people can truly feel the difference. In my case though, it wasn't a matter of a self diagnosed IBS or colitis, with occasional diarrhea or gas or whatever. It was a serious and basically incapacitating condition. I went from being in the best shape of my life getting ready for Ranger school to less than a year later unable to run a mile, or stay awake through a full day. I was malnourished and anemic. (I won't even get into the difficulties of shitting myself self several times a week) Anyone can say anything on the internet, so I've read a lot of "testimonials" about miracle cures such as the one you linked, but the places where people who are actually diagnosed with IBD are, are nearly silent on any of these recommendations. For me (and the few other people I know personally with chron's or colitis) the only thing to have any positive effect were immunosuppressant drugs, the same thing you would get if you got an organ transplant. Some are able to get by on just milder drugs. There are extremely severe risks, and not only that but I had to give up my career in the Army. Believe me, if it were simply a matter of taking some herbal supplements and dropping caffeine (which I avoid for the most part as is) I would've done it in a heartbeat. I rarely bring it up, on the internet or otherwise, because it tends to have this effect of people coming out to give advice - I know you and everyone else means well - but it's a issue very few understand (even most doctors!) and I've yet to hear something new or of any value. With that said I'll restate my original advice which is if something is definitely wrong, you need to go see a doctor. I hope I didn't come across as too abrasive. The internet is great for a lot of things, medical advice is not one of them.
