Drinking warm water with baking soda (8oz+1teaspoon b/s) 2 glasses per day will help to alkalize, eating an alkaline diet (check Dr.Young's books in the library + on-line), also drinking calcium bentonite clay like Pascalite clay or if you have a heavy diarrhea use Living clay, all of these will alkalize you. Also, drinking herbal teas are alkalizing.
For me Pascalite clay is a life saver (relieve pain, reduce diarrhea, help with inflammation...) and drinking baking soda with warm water will relieve the pain and help the cramps.
The whole idea of alkalizing might not be the cure for UC but surely a valubale approach and worth considering.
Some people on this forum think I am a "crazy nut" for even talking about acid and clay....
Just my opinion.
