| Outline of Final Research Achievements |
Goshajinkigan, one of the traditional Japanese Kampo formulas, has been used for neuropathic pain. However, how goshajinkigan suppresses the neuropathic pain are still unclear. In this study, we investigated the effect of Goshajinkigan and those ingredients to the voltage-gated sodium channels current (VGSCs) of Nav1.7 which predominantly expresses in peripheral nerve, particularly dorsal root ganglion using HEK293 cells expressing human Nav1.7 VGSCs. Our finding suggested that goshajinkigan may exhibit suppression of the neuropathic pain via Nav1.7 Na+ current inhibition by multiple components included in goshajinkigan.
