Objectives: We sought to determine the effect of topical application of(black seed) oil, on the primary dysmenorrhea intensity.
Methods: We conducted a randomized, double-blind clinical trial on 124 female students, 18-22 years old, living in the dormitories of Sabzevar Universities. After a primary assessment, participants were randomly divided into two groups. The first group rubbed two drops ofoil, and the second group rubbed liquid olive oil, as the placebo. Massage was performed on the fontanel lobe 3, at night, three days before menstruation, for eight consecutive days (about five days after menses). This procedure was repeated for three menstrual cycles. After three cycles, pain severity was measured by the visual analog scale. Data analysis was carried out using the Mann-Whitney U test and analysis of covariance (ANCOVA).
Results: This study was conducted on 124 female students. The mean age of students, mean age of first menarche, body mass index, and pain severity were not significantly different in the two groups (>0.050). No adverse effects were observed during the study. The results of ANCOVA showed that pain intensity inoil group was significantly decreased compared to that of the placebo group (0.6 score;<0.050).
Conclusions: .could be a promising, safe, and easily available analgesic supplement in women suffering from primary dysmenorrhea.
