Hypericum perforatum is used as an alternative treatment of depression, which is a disease that has been affecting women during post-partum or gestation. There is little information in experimental studies regarding the reproductive toxicity of hiperic. The present paper aims at assessing Hypericum perforatum's embryotoxic potential. Pregnant Wistar rats were treated with 36 or 360 mg/kg body weight of Jarsin dried extract, via oral gavage on days 5 and 7 post-insemination. Animals from the control group received 0.5 mL of distilled water through the same via and days. The animals were killed on the 15th day and the following variables were analyzed: maternal and fetal body weight, food intake, clinical signs of toxicity, weight of ovaries and placenta, number of corpora lutea, resorptions, live and dead fetuses, and the proportion of implantation and resorption. No significant differences were observed in any of these variables, leading to the conclusion that in the experimental model used, Hypericum perforatum does not seem to be toxic to the mother, does not interfere with blastocyst implantation nor does it seem to be toxic to the embryo.
