Drinking certain types of teas can help manage ulcerative colitis. Teas come in many different varieties, including green, black, and earl gray. To treat ulcerative colitis, chamomile tea is one of the best options, due to its anti-inflammatory properties. Drinking this tea can help soothe pain, and reduce diarrhea as well as other digestive-related symptoms. To use chamomile tea, add a few teaspoons of dry chamomile flowers to a cup of boiling water. Steep the mixture for around 5 minutes, and strain. Drink the tea when necessary; you can also try drinking it after a meal to reduce symptoms.
