Primary dysmenorrhea occurs in as many as 50% of female adolescents and is associated with significant decreases in academic performance, sports participation, and socialization with peers. Complementary and alternative medicine treatment options are of interest to patients and health care providers. The use of rose tea to alleviate menstrual pain has long been a part of folk knowledge around the world but has not been studied scientifically. To determine the effectiveness of drinking rose tea as an intervention for reducing pain and psychophysiologic distress in adolescents with primary dysmenorrhea, 130 female adolescents were randomly assigned to an experimental (n = 70) and a control (n = 60) group. Preintervention and postintervention data at 1 month, 3 months, and 6 months were gathered on the biopsychosocial outcomes of dysmenorrhea. The results showed that compared with the control group, the experimental group perceived less menstrual pain, distress, and anxiety and showed greater psychophysiologic well-being through time, at 1, 3, and 6 months after the interventions. Findings suggest that drinking rose tea is a safe, readily available, and simple treatment for dysmenorrhea, which female adolescents may take to suit their individual needs.
