Cao, female, 32 years old. Diagnosed on March 4, 1978. Abdominal pain, diarrhea, and loss of appetite for over a month. At the time of my examination, the patient appeared emaciated, with abdominal distension and fullness, pain that was relieved by warmth and pressure, loss of appetite, diarrhea 4-6 times a day, with loose stools or undigested food in stool. The tongue was pale with a white coating, and the pulse was slow and weak. This belongs to taiyin spleen deficiency and cold, and should be treated with warming. Middle-Regulating Pill was prescribed, to be taken three times during the day and twice at night, 2 pills each time. After 4 days, the diarrhea stopped. On the night of March 7 at 12 o'clock, the patient began to feel hungry, and thereafter appetite gradually increased. After half a month of recuperation, the patient recovered. From the time the patient began to feel hungry at midnight on March 7, the condition took a turn for the better, which also coincides with "taiyin disease, two-hour periods of symptom alleviation, from hai to chou."
