Boi-Ohgi-To is considered to regulate water metabolism, and to potentially to contribute to improving the condition in patients with Meniere’s disease. We studied the efficacy of the herb medicine “Boi-Ohgi-To” prescribed for Meniere’s disease. Boi-Ohgi-To was given orally 3 times a day at the total dose of 7.5 g for 6 months. Data of a total of 14 patients were analyzed (5 men and 9 women; age 42–79 (median age 67) years). We excluded the patient who reported increased frequency of micturition as a side effect, and analyzed the clinical effect of the herbal medicine in the remaining 13 patients. The improvement rate of dizziness/vertigo was 69% (9/13) and that of the hearing acuity was 30% (3/10) and the rate of overall improvement was 69% (9/13).
We concluded that Boi-Ohgi-To is one of the useful therapeutic options for Meniere’s disease.
