Ginger appears relieve menstrual pain more than placebo.
Another Iranian study focuses on ginger, but for a much different population: high school females. In a short four-day trial, researchers assigned 105 high school students to ginger, zinc sulfate, or placebo daily. The aim of this study was to detect potential pain relief with ginger during menstruation.
Students consumed their ginger, zinc sulfate, or placebo from the day before menstruation to the third day of bleeding. Both ginger and zinc were associated with more self-reported pain relief than placebo during intervention. Full details of the study are now published in Pain Management Nursing.
