ABSTRACT
We report a case of rheumatoid arthritis (RA) that was successfully treated with Kei-kyo-so-so-o-shinbu-to. A 56-year-old woman had been receiving treatment in our department for RA since 1992, and polyarthralgia and multi-joint swelling had become exacerbated from the beginning of April 2003. C-reactive protein and erythrocyte sedimentation rate were elevated. She was hospitalized on_??_, but even with some Kampo formulas, these levels did not improve. The epigastric region was extended and appeared to be in a state of “Hotori-senpai” from _??_, and the administration of Kei-kyo-so-so-o-shinbu-to was begun on _??_. From the next day, pain, swelling of joints, and the “Hotori-senpai” status began to improve, as did the inflammatory reactions. Thus, it was considered, when Kei-kyo-so-so-o-shinbu-to was prescribed, focusing on the “Hotori-senpai”, “Ki-bun” and “Sui-in” status of this patient, that this prescription exerted immediate favorable effects.
