Red Ginseng extract blocks histamine-dependent itch by inhibition of H1R/TRPV1 pathway in sensory neurons

Korean Red Ginseng – a steamed root of Panax ginseng Meyer – has long been used as a traditional medicine in Asian countries. Its anti-pruritic effect was recently found, but no molecular mechanisms were revealed. Thus, the current study focused on determining the underlying molecular mechanism of Korean Red Ginseng extract (RGE) against histamine-induced itch at the peripheral sensory neuronal level.
