A 91 years old patient was diagnosed with end stage bladder cancer. He was sent to the hospital because of vomiting with blood from the gastrostomy. At the same time he also had pneumonia and urinary tract infection. During hospitalization, he had watery diarrhea several times a day for nearly one month, even if treated with many kinds of antidiarrheal medicines.

The patient’s symptoms of diarrhea were large intestinal dryness accumulation, bowel qi stagnating, and heat accumulation with watery discharge.
