Abstract
Background: Dysmenorrhea is seen in nearly 5% of women with regular menstruation. In this regard, different methods have been proposed for treatment of dysmenorrhea, and drugs with fewer side effects are preferred. Hence, this study was done to detect the effect of echinophora- platyloba on primary dysmenorrhea. Materials and Methods: In a single-blind clinical trial, 60 students with primary dysmenorrhea were evaluated at Shahr-e-Kord University of Medical Sciences. The students were randomly divided into two groups of 30 each: Echinophora-platyloba extract and placebo. Data collection was done through visual analogue scale for detecting the intensity of pain. At the end of first and second months after treatment, the intensity of pain was determined in the two groups and compared with that before the intervention. Eventually, the data were analyzed through Chi square, t-test and Mann-Whitney test. Results: The means of dysmenorrhea severity scores two months before administering the drug in echinophora-platyloba and placebo groups were 8.46±2.75 and 8.80±2.53, respectively. Here the difference was not significant however, after administering the drug, the mean scores in intervention and non-intervention groups were 3.41±1.12 and 7.82±2.60, respectively, which indicated a significant difference between the two groups (p<0.001) . Conclusion: Both echinophora-platyloba extract and the placebo could reduce the severity of dysmenorrhea during the treatment, yet the effect of echinophora-platyloba was much greater than the placebo. Thus, the use of echinophora-platyloba extract is suggested in treatment of dysmenorrhea.

Abstract
Background: Irritable bowel syndrome (IBS) which is characterized by chronic abdominal pain and changes in bowel movements is the most common gastrointestinal disease. Curcuma is one of the traditional medications which has been considered in treatment of gastrointestinal diseases. In this study, the effects of curcuma on IBS were investigated. Materials and Methods: In a double-blind randomized study, 140 IBS patients after meeting the inclusion and exclusion criteria, regardless of sex and age and based on internist’s diagnosis, were involved. The patients were randomly divided into case (curcuma) and control (placebo) groups which included 69 and 71 patients, respectively. For converting subjective criteria to objective ones, treatment forms were filled out before the treatment and two and four weeks after the treatment according to visual analog scale. Data were analyzed through descriptive statistics and t-test. Results: Using curcuma and placebo before the treatment and two and four weeks after that improved patients’ clinical symptoms except for vomiting (p=0.001) however, no significant differences were observed in the effectiveness of placebo and curcuma on improvement of clinical symptoms of patients in case and control groups (p>0.05). Conclusion: Using curcuma does not offer any significant differences in controlling and reducing the symptoms of IBS in comparison to the placebo, but its application improves the clinical symptoms of IBS patients.
