Background: Oxytocin, the most common medicine for labor induction, has maternal and fetal side effects and sometimes is not effective. Herbal medicines are alternatively utilized as safe methods. Dill includes tannin, which is a polyphenol with contractile properties, is potentially supposed to be able to induce uterus contractions. Objectives: The current study aimed to test the effects of Anethum graveolens (dill) seeds on induction of labor and compare it with oxytocin in term pregnancy. Patients and Methods: A randomized clinical trial was conducted on 100 eligible participants without any delivery signs such as labor pain, rapture of membranes or bloody show. Participants were allocated to either the case or control group and receiving boiled Anethum graveolens seeds or induction with oxytocin, respectively. Therefore, 0.018 g/kg of dill seeds with a spoonful of sugar was solved in 250 mL of boiling water and brewed for about 10 minutes. Then it was filtrated. Subjects in the case group drank this solution only once after admission and they were infused with simple Ringer solution. The control group received standard protocol of labor induction with oxytocin. Participants were followed up to the delivery time. Results: Case group had a significantly better Bishop score following the intervention compared to the control group. The mean duration of active phase, second and third stages of labor were significantly lower in the case group. The control group had shorter latent phase than the case group. Conclusions: Results showed that the boiled Anethum graveolens seeds was effective on labor induction.
