Efficacy of Keishibukuryogankayokuinin for Tinnitus with Blood and Water Stagnation

Abstract

Keishibukuryogankayokuinin (KBGY) is a Kampo formulation that is well known as being suitable for patients with blood and water stagnation. In this study, we retrospectively investigated the efficacy of KBGY for tinnitus patients. The total number of patients was 9 (5 males, 4 females). The average age was 67 years (range : 54-81 years, the median age : 65 years). The progression of 9 patients was cure (1), amelioration (6), no change (2), and deterioration (0). The important pathophysiology of tinnitus in Kampo medicine includes blood stagnation and water stagnation. In these cases, KBGY can single-handedly improve both blood and water stagnation. We recommend KBGY for the treatment of tinnitus caused by the coexistence of blood and water stagnation.
