How do you cure colitis?

Colitis is a general: term for inflammation of the colon. This can be infectious, vascular, idiopathic and each is treated differently. I can't adequately address this question with out a more specific diagnosis and you need this as well by seeing a good gastroenterologist or colon and rectal surgeon for correct work up and treatment regimen

Need more info: Without knowing more about the type of colitis you have been diagnosed with, it's difficult to better guide you. If you can be more specific about what type of colitis you have we can better guide you. Know that some forms of colitis can't be cured but rather controlled in the long run.
