Li, female, 40 years old, visited in April 1985. The patient had intermittent low-grade fever for over a year, with fever mostly occurring around 3 PM, sometimes at night, with body temperature between 37°C and 38°C. Previous treatments for yin deficiency were ineffective. Oral anti-inflammatory drugs and Chinese medicinals heat-clearing formula could temporarily stop the fever, but it would recur after 5-6 days or more than ten days. Using offensive purgative formula could prolong the interval between episodes. Due to the prolonged duration, the effects were not significant, and intravenous fluids were administered, which could temporarily stop the fever. This cycle repeated for over a year, with multiple examinations failing to identify the cause. Examination revealed poor contraction function of Dannang (EX-LE6) but no other abnormalities. I was invited to treat the patient.

Symptoms included low-grade fever of 37.592°C, dry mouth and tongue, poor appetite, abdominal distension and fullness, constipation occurring every 3-5 days, sometimes passing hard stools, talking in sleep as if seeing ghosts, red tongue with yellow coating, and a deep, strong pulse. According to Article 212 of the "Cold-Damage Disease Treatise," which states "no bowel movement for 5-6 days, up to more than ten days, with tidal fever in the afternoon," it was diagnosed as yangming fu-organ pattern. Major Purgative Decoction was prescribed. Prescription:
Rhubarb Rhizoma 12g (to be decocted later), Mirabilite 15g (dissolved in boiling water), Magnolia Bark 12g, Immature Orange Fruit 9g
About 2 hours after taking the medicine, bowel movements were stimulated, with borborygmus and 8 bowel movements in a day, passing turbid water and hard stools. The accumulated waste was eliminated, the pulse became calm, and the body returned to normal, resulting in a cure.
