In this Phase III study, the herbal product Vitex agnus-castus BNO 1095 20 mg will be tested. The sponsor would like to find out if treatment with Vitex agnus-castus BNO 1095 20 mg may improve the cramping pain before or during menstruation (primary dysmenorrhea) (without an organic cause) in women and if this treatment is safe. It is tested, if the pelvic pain and other symptoms during menstruation improve in patients who are treated with Vitex agnus-castus BNO 1095 20 mg and if therefore the standard treatments for primary dysmenorrhea, for example pain relief medications will not have to be increased. The study has 2 treatment groups. Patients in one group will receive Vitex agnus-castus BNO 1095 20 mg, and patients in the other group will receive a placebo. Placebo tablets look like Vitex agnus-castus BNO 1095 20 mg tablets but have no active ingredient. Patients will be randomly assigned (like tossing a coin) to one of the 2 groups (this process is called randomization). The chance for the patients to receive Vitex agnus-castus BNO 1095 is 50%. Neither the patients nor the investigators know which product the patients are taking (this method is known as "double-blind").
