Objectives:
Primary dysmenorrhea in the absence of pelvic pathology is a common gynecologic disorder affecting the quality of life of women of reproductive age. This study evaluates the effect of salix extract on primary dysmenorrhea.
Design:
This study was a randomized crossover clinical trial.
Setting:
The study population included 96 female students with level two or three of primary dysmenorrhea: 48 students in the treatment group (sequence I) followed by control (sequence II) and 48 students in control group (sequence I) followed by treatment (sequence II).
Interventions:
The intervention was salix capsule (400 mg daily) and the active control was mefenamic acid capsule (750 mg daily) as.
Main Outcomes:
Pain intensity, measured by the visual analog scale (VAS), amount of bleeding, and severity of dysmenorrhea symptoms were outcomes. Generalized estimating equations were used for data analysis.
Results:
The demographic and menstrual characteristics of the students were homogenous between the groups. The results showed that the students in mefenamic acid group had a significantly higher level of VAS than the students in the salix group over time (1.61 ± 0.06, P < 0.001). The estimated odds of the bleeding level in the salix and mefenamic acid group were not significantly different (P = 0.31). In average, 77.39%±16.18 of the students in salix group showed no symptoms followed by 22.18%±14.08 of the students who experienced mild symptoms. Averagely, 44.58%±20.16 of the students in the mefenamic acid group had mild symptoms followed by moderate symptoms (28.12%±15.29).
Conclusions:
Salix extract significantly decreased dysmenorrhea in comparison to mefenamic acid, as the standard treatment of dysmenorrhea.

Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
