The aim of this study was to report eight patients with dizziness, diagnosed as Qi-dizziness. The cause of Qi-dizziness is seven emotions(七情), and seven emotions induce liver qi depression(肝氣鬱結), spleen deficiency(肝脾不和) and dual deficiency of the heart-spleen(心脾兩虛). Guibisoyo-san($Gu={i}p'{i}xi={a}oy'{a}o-s`{a}n$) modified formula, which can treat the above diagnosis, was given to patients three times a day. To evaluate the therapeutic effect, visual analog scale(VAS) and inconvenience degree (ICD) were examined. After treatment, the VAS score decreased 7.37 points on average and ICD score decreased 1.62 points on average in patients with both peripheral vestibular dizziness and nonvestibular dizziness. This study shows that herbal therapy by traditional Korean medicine has considerable effects on dizziness, regardless of the etiological cause.
