We report a case of burning mouth syndrome (BMS) in a woman in her 70s whose pain was relieved by goshajinkigan alone. Five years ago, she became aware of tongue pain when she was under emotional stress. We diagnosed it as BMS. Since she had been taking antidepressants for depression for a long time and was more bothered by symptoms of kidney deficiency, such as back pain and numbness in the lower limbs, than tongue pain, we first prescribed goshajinkigan to improve her general condition. After that, not only her kidney deficiency but her BMS was relieved. The patient is currently under follow-up, but there is no tendency to relapse BMS. We presume that the correction of the patient’s general condition by Kampo medicine would lead to the improvement of her BMS.
