Dong, female, 11 years old, first visited on May 29, 1987. The patient had a weak constitution and developed a fever four days prior due to being caught in the rain. After taking Western antipyretic and analgesic medication, the fever subsided but then recurred, presenting with alternating chills and fever. Additionally, the patient experienced gastric stuffiness, epigastric obstruction, frequent nausea and vomiting, and an inability to eat. The Western medical treatment for acute gastroenteritis, including anti-inflammatory and fluid replacement therapies, was administered for two days with poor results. Switching to Chinese medicinals yielded similar symptoms, and the patient had not had a bowel movement for four days. The original formula of Minor Bupleurum Decoction was prescribed, with a heavy dose of Skullcap Root (30g). After one dose, the patient had a bowel movement, the chills and fever ceased, nausea and vomiting decreased, and gastric stuffiness and pain were mostly relieved. However, appetite remained poor and physical strength was still lacking. The treatment was then adjusted to a stomach-harmonizing and calming formula, and after three days of regulation, the patient recovered.
