Plants such as Annona nutans used in folk medicine have a large number of biologically active compounds with pharmacological and/or toxic potential. Moreover, pregnant women use these plants indiscriminately, mainly in the form of teas, without being aware of the harm that they could cause to the health of the embryo/fetus. Therefore, it is necessary to analyze the potential toxic effects of medicinal plants during gestation. The present study aimed to evaluate the effects of A. nutans hydromethanolic fraction leaves (ANHMF) on mutagenic and immunomodulatory activity, reproductive performance, and embryo-fetal development in pregnant female mice. The animals (N = 50 female and 25 male) were divided into 5 groups: Control, Pre-treatment, Organogenesis, Gestational, and Pre+Gestational. The results indicate that ANHMF mainly contains flavonoid and other phenolic derivatives. It was found that it does not exhibit any mutagenic or immunomodulatory activity, and it does not cause embryo-fetal toxicity. Based on the protocols used in the present studies, our analyses confirm that it is safe to use ANHMF during pregnancy.
