Gestational exposure to Byrsonima verbascifolia: Teratogenicity, mutagenicity and immunomodulation evaluation in female Swiss mice

Ethnopharmacological relevanceByrsonima verbascifolia is used in folk medicine to treat diarrhea, intestinal infections, chronic wounds, Chagas disease, inflammation and as a diuretic. However there is no investigation regarding the Byrsonima verbascifolia hydrometanolic extract (BVHME) used during gestation.Materials and methodsThe pregnant females were randomly divided into 5 groups. Control group received saline plus DMSO (1%) in a volume of 0.1 mL/10 g (b.w.), via gavage, for at least 15 days prior to mating and throughout the gestational period. The Pre-treatment group received the BVHME, via gavage, at a dose of 50 mg/kg (b.w.) for at least 15 days prior to mating and up to the appearance of the vaginal plug. The Organogenesis group received the BVHME at a dose of 50 mg/kg (b.w.), via gavage, on the 5–15th gestational day. The Gestational group received the BVHME at a dose of 50 mg/kg (b.w.), via gavage, throughout the gestational period (from the 1st to the 18th day of pregnancy). The Pre+Gestational group received the BVHME at a dose of 50 mg/kg (b.w.), via gavage, for at least 15 days prior to mating and up to throughout the gestational period. The clinical signals of maternal and fetuses toxicity were evaluated, as the mutagenicity and immunomodulation tests were performed.Results and conclusionsThe present investigation shows, for the first time, that the use of Byrsonima verbascifolia extract in pregnant Swiss mice, did not alter the female reproductive function, mutagenicity or immunostimulation as well as not interfere with embryofetal development at least in our experimental conditions.
