Efficacy of butterbur in allergic rhinitis: a cell culture study

CONCLUSIONS: Cytotoxicity on nasal cells was not observed after the butterbur application. Even if there have been some indications of liver toxicity, butterbur can be suggested as a safe option for seasonal allergic rhinitis. Further studies related to the toxicity of topical butterbur are also recommended, even though this study indicates no cytotoxicity from the topical application on nasal cells.PMID:37350686 | DOI:10.26355/eurrev_202306_32725
