Drink Chamomile Tea
Chamomile is good for treating intestinal inflammation, and it has antispasmodic properties as well. You can brew yourself a cup of chamomile tea from packaged tea bags, or you can buy chamomile flowers and steep 1 teaspoon of them and 1 teaspoon of peppermint leaves in a cup of boiling water for fifteen minutes. Drink 3 cups a day. Also the tannins in ordinary black tea have an anti-diarrheal effect.
