Embryotoxicity and teratogenicity studies of an ayurvedic contraceptive--pippaliyadi vati

An ayurvedic contraceptive--pippaliyadi vati, containing equal parts of powdered seeds or fruit berries of Embelia ribes, fruit of Piper longum and borax powder was fed orally to two groups of pregnant rats: 2.5 times to one and five times to the other; the recommended dose for humans. The foetuses of mothers fed with pippaliyadi had low birth weights and were smaller in length. The mothers gained less weight during gestation. Developmental defects of soft tissues and skeletons were analyzed. There were instances of herniation of the intestines into the umbilical cord in foetuses of mothers who were administered pippaliyadi. The control and the gum acacia groups did not show such herniation.
