Yerba Mate (Ilex paraguariensis) is historically used as a beverage and its extracts are considered traditional medicine in South America. Extract use has been expanding to North American and European markets and the currently available genetic toxicology literature indicate discrepancies in genotoxicity findings for yerba mate. As botanical extract use expands, assumption in safety should be made with caution assuring a good understanding of the test material characterization. Authoritative agencies suggest a two-step paradigm to investigate genotoxicity, and this was implemented to evaluate the safety of yerba mate hydroxycinnamic acid extract. Four OECD compliant assays were employed: bacterial reverse mutation, in vitro micronucleus and a parallel in vivo micronucleus, and comet assay. No evidence of mutagenicity was observed in the in vitro Ames assay, but the results of an in vitro micronucleus study were inconclusive. However, oral gavage treatment of rats for the in vivo micronucleus and comet assays demonstrated negative findings. The results from this battery of tests, supports that this yerba mate hydroxycinnamic acid extract is not anticipated to pose genotoxicity concerns. A high-level comparison of results to other available genotoxicity literature on yerba mate is presented with emphasis on the importance of identity when drawing conclusions on botanicals. |
