Use Yerba Mate Tea.
It has eliminated all my ulcerative colitis symptoms for over a year. Before I started drinking it, I had terible symptoms (in and out of the hospital) for 4.5 years.
Put 1 tbsp of the tea in a tea-steeper. Mix 1/2 cup of boiling water with 1/2 cup of room temp or cold water in a glass. Pour that glass in the tea steeper. Let it steep for at least 1 hour. Drink this once a day for a month. If you don't see improvement, do this twice a day.
I'm not a doctor or anything, but this is the only thing to eliminate all of my symptoms.
Just so you know, when I stop drinking the tea, in about 2 weeks, i'll start to bleed again, but negligbly. So, it doesn't cure you, but it is essentially a herbal medication that works wonders.
