ABSTRACT
A42-year-old man presented with a history of tidal fever almost every evening to night with 10-year duration. We could not find out the cause of his fever, so we thought he was classified in fever of unknown origin. The patient suffered from an anhydrosis phase during the temperature rose, but his fever broke after perspiration occurred at the end. The lack of perspiration with fever is a typical symptom of excess pattern of tai yang stage, and fever at night is suggestive of shao yang stage. Saikatsugekito was thought to be best suited as it would address both stages. The formula promoted perspiration, and the body temperature remained stable thereafter. It is not unusual to encounter complicated symptoms due to combined or overlapped pattern in clinical setting. This case represented successful outcome by identifying and analyzing the concept of gobyo and heibyo and prescribing a formula accordingly.
