Cynara scolymus (C.scolymus) is a plant employed worldwide as an herbal medicine. However, there is a paucity of data related to the evaluation of its toxicity in commercial preparations; thus, the aim of this study was to evaluate the possible teratogenic effect of the dry extract of C.scolymus leaves in Wistar rats. Females were treated, from gestation day (GD) 6 until GD19, with 0.0, 1.0, 2.0 or 4.0 g/kg body weight of C.scolymus extract. At GD20, a cesarean section was performed for evaluation of maternal and fetal parameters. C.scolymus did not induce changes in food consumption, preimplantation or postimplantation losses, placental weight or biochemical profile. An increase in water consumption was observed in pregnant females treated with the higher doses of C.scolymus. Experimental groups showed lower body weight gain during pregnancy and lower gravid uterus weight. Maternal body weight minus the gravid uterus weight did not result in significant differences. Reductions in fetal weight and length were observed in experimental groups. The number of live pups per litter was lower in the highest dose group. No fetal skeletal or visceral malformations were detected. The results showed that the consumption of artichoke during pregnancy clearly has a negative impact on fetuses.
