Helleborus, a genus of perennial flowering plants native to Europe, Asia, and North Africa, has a long history of traditional use. While specific traditional uses for individual species are not well-documented, Helleborus niger (common hellebore) was historically used in European folk medicine for various ailments, including as a purgative and diuretic. Scientific evidence is limited but suggests some potential benefits; one study indicated a possible improvement in cognitive function with subcutaneous administration of Helleborus niger 12x compared to controls, though this finding requires further validation. Another study isolated two new steroidal saponins from Helleborus thibetanus, which showed no significant cytotoxicity against tested cancer cell lines, and a third found that extracts from Helleborus odorus subsp. cyclophyllus roots exhibited antioxidant properties and induced cytotoxic effects in bacterial and mammalian cells. Safety data is currently inconclusive but does not report any major issues; similarly, there are no recorded drug interactions at this time.
