One of the most common gynecological issues women face is menstrual cramps. Peppermint tea contains menthol, which has muscle relaxant properties. Drinking peppermint tea may help reduce the severity of menstrual cramps by relaxing the muscles of the uterus and easing the pain. Although more scientific research is needed to definitively prove its efficacy, many women report experiencing relief from cramps after consuming peppermint tea.
