Goreisan is a traditional Kampo medicine with diuretic effects, commonly used for treating dizziness and headaches in the field of otorhinolaryngology. This study explores the clinical application of Goreisan, particularly its efficacy in vestibular migraine and Ménièreʼs disease. Vestibular migraine is characterized by recurrent dizziness and migraines, while Ménièreʼs disease involves hearing loss and vertigo caused by endolymphatic hydrops. Our findings indicate that Goreisan, either alone or in combination with other Kampo medicines (such as Goshuyuto and Ryokeijutsukanto) , is effective for these conditions. Case reports demonstrate that combined Kampo therapy, including Goreisan, contributed to the treatment of intractable Ménièreʼs disease and vestibular migraine. While Kampo combination therapy is a valuable treatment option, considerations regarding insurance coverage and potential side effects must be addressed. This study highlights the utility of Goreisan in otorhinolaryngology and suggests the need for further research.
