[Review of classical prescriptions in treatment of ulcerative colitis].

Ulcerative colitis(UC) is a continuous inflammatory bowel disease with the main clinical manifestations of abdominal pain, diarrhea, and mucous bloody stools, mainly attacking the colorectal mucosa and submucosa. It is characterized by high recurrence rate, difficult cure, and clustering and regional occurrence. Chinese medicinal prescriptions for the treatment of UC have good therapeutic effect, multi-target regulation, slight toxicity, and no obvious side effects.
