Thereare limited articles on the effectiveness of this medicinein inducing delivery. The present study was designed andconducted with the objective of investigating the effectivenessof vaginal administering of evening primrose ininducing delivery.Study Method: the present study is a triple blind caseevidenceclinical trial. Out of the individuals featuring therequired qualifications for entering the study, 160 wererandomly selected and assigned into two equal groups.Following the acquisition of the consent letter, the participantswere subjected to clinical examinations. Theirpreliminary information was recorded. Then, two softprimrose capsules were placed in the posterior choledosacof the intervention group participants. Placebo capsuleswere used in control group. Next, the patients wereasked to leave a contact number for the future requiredfollow-ups in terms of the delivery pain commencementand labor duration and delivery time. In the end, the collectedinformation was analyzed using SPSS.Result: based on the analyses, the two groups were notfound significantly different in terms of the demographicdata. Moreover, no significant difference was observed interms of the interval between the primrose administrationand delivery pain initiation (T1) and the interval betweenprimrose use till delivery (T2) as compared to the controlgroup (P>0.05).Discussion: it seems that the vaginal application of primrosecapsule is not effective in cervix preparation. However,there is a need for further research in this area. Thecurrent studies on the effectiveness of the evening primroseis limited to two researchers that have also foundresults consistent with what has been found here and twoother studies with results not in accordance with the currentpaper’s findings. More comparative studies seem tobe useful in this regard.
