Introduction: Medicinal herbs have a history as old as human creation and using them as a healing agent has been common all over the world since anci-ent times. Medicinal herbs have been also used in treating dysmenorrheal as one of the most common gynecological problems in women. In recent years, a variety of nutrition therapies have been used for the treatment of dysmen-orrheal. But considering that the use of any medication has side effects in addition to therapeutic effects, using chemical plants along the drug may be helpful in the treatment of dysme-norrheal. Therefore, this study aimed to determine the effect of medicinal herbs in relieving the symptoms of dysmenorrheal among female students in Ardabil University of medical scie-nces.
