Motherwort (Leonurus cardiaca) has a long history of use in traditional herbal medicine for the relief of menstrual cramps and other gynecological complaints. Its use can be traced back to ancient Greek and European herbal traditions, where it was commonly recommended to "ease the womb" and promote menstrual flow. The herb contains several active compounds, including leonurine and stachydrine, which are thought to have mild antispasmodic and uterotonic properties, potentially helping to relieve smooth muscle spasms associated with menstrual cramps. However, the majority of evidence for motherwort's efficacy in treating menstrual cramps is based on traditional use and anecdotal reports rather than rigorous scientific studies.

Modern research on motherwort for menstrual pain is limited. While some laboratory and animal studies suggest that its constituents may have muscle-relaxing and anti-inflammatory effects, there is a lack of well-designed clinical trials in humans specifically addressing menstrual cramps. Most contemporary herbalists continue to use motherwort based on its traditional reputation, but mainstream medical organizations do not endorse it due to insufficient scientific evidence. Overall, motherwort's use for menstrual cramps is supported more by history and tradition than by robust clinical data.
