Detailed Description:

Crohn's disease, a chronic condition resulting in inflammation of the gastrointestinal tract (GI), causes a person to experience persistent symptoms of inflammatory bowel disease, including abdominal pain, nausea, vomiting, rectal bleeding, diarrhea, and constipation, with infrequent bowel movements that are at times accompanied by a sensation of incomplete emptying after having a bowel movement. Tsumura's TU-100 is a modern herbal product that has been approved as a prescription drug in Japan. Several lines of evidence indicate that TU-100 attenuates intestinal inflammation in Crohn's disease by increasing intestinal blood flow and stimulating a protective lining of intestinal mucus which produces an anti-inflammatory effect. TU-100 may attenuate pathological changes in the intestine and reduce symptoms in patients with Crohn's disease.
