Zhang, male, 43 years old, visited on March 8, 1994. The patient was exposed to rain while working in the fields 10 days ago, followed by fever and headache, and fatigue in the limbs. He was treated at a local health center as a common cold and had taken Mulberry Leaf and Chrysanthemum Decoction, Lonicera and Forsythia Powder, Bupleurum and Calming Decoction, Apricot and Perilla Decoction, and A.P.C. among other Chinese and Western medicines. His body temperature fluctuated and did not normalize, so he came to our hospital for outpatient treatment.

At the time of examination: fever with a body temperature of 38℃, without sweating, thirsty and drinking a lot, red lips and flushed face, short and yellow urine, red tongue with yellow coating, floating and slippery pulse, and a strong pulse at the chi position. Examination showed red blood cells at 4.5×10¹²/L, white blood cells at 10.5×10⁹/L, and no abnormalities in urine tests.

The syndrome is attributed to yin deficiency with dampness-heat lingering in the lower jiao. The treatment should focus on nourishing yin, clearing heat, and promoting diuresis. The prescription used was Polyporus Decoction with 15g each of Moutan Cortex and Chinese Wolfberry Root-bark. After one dose, sweating was observed, and the fever significantly subsided. The prescription was continued with the addition of 15g each of Ophiopogon Tuber and Coastal Glehnia Root, and after three doses, all symptoms were completely resolved.
