I've started chiropractic trestment. My chiro doesnt claim to be able to heal UC but does claim to be able to minimise the stress your body is under my ensuring everything is structurally sound and that your nervous system is working efficiently. Reducing stress can only help UC.
A lot of people use acupuncture and chinese medicine. UC is related to the chinese element "Metal" which is governed by the lungs and the colon. I think they work to free up this meridian via treatment. I don't know too muc about it. You can read a lot more about the 5 element theory of acupuncture online.
I really liked the following website on natural therapies for colitis. The doctor doesnt try to forcefully claim that all UC is curable by therapy. But ho does talks sense

I really like the paragraph where he says
"Emotional stress is such a significant contributor to the pathological process of ulcerative colitis that if I developed a moderate to advanced case of ulcerative colitis, one of the first steps that I would take would be to arrange to take time off from work so that I could give my mind and spirit time to rest and return to a state of harmony. I'm certain that to not take this step would be to markedly reduce my chances of experiencing a full recovery."
