A 44-year-old woman became easily fatigued after her second childbirth. Her symptoms improved with shimbuto and ninjinto as a substitute for bukuryoshigyakuto, and the prescriptions were continued. Recently, she suffered from fever, pain around thyroid glands, palpitation, and tremor of hands. She was diagnosed with subacute thyroiditis and prescribed acetaminophen, but the symptoms did not resolve. Based on the clinical signs of inappetence and her thick yellow tongue coating, we suspect the late yang stage and administered shosaikoto. Her body temperature remained below 37 degrees Celsius thereafter, and the pain around thyroid glands disappeared. Out of all the Kampo formulae used in 310 cases of subacute thyroiditis including past reported cases and this case, we found that 53% of the effective formulae were what we call formulae of involving Bupleuri radix that contain both of Bupleuri radix and Scutellariae radix. It is considered that formulae of involving Bupleuri radix are often effective to control the inflammatory process in subacute thyroiditis.

A 20-year-old woman had a tendency of belching from a young age. She began to realize that she might have excessive belching compared to other people for the past two years. She was prescribed some medicines to improve gastrointestinal function by some physicians, but her symptoms did not resolve. Aerophagia was suspected as forceful belching tends to occur soon after eating or drinking. Incidentally, ihon is a condition in which one vomits food half a day after the ingestion due to the malfunction of the digestive system. I considered her symptoms as ihon and prescribed bukuryotakushato, and her symptoms improved. This case report indicated that ihon could be defined as a symptom of forceful regurgitation of food or air, regardless of the timing after meals.
