Lady's Mantle (Alchemilla vulgaris) has a long history of traditional use in European herbal medicine, particularly for women's reproductive and vaginal health. Traditionally, it has been used to address issues such as heavy menstrual bleeding, menstrual cramps, and to aid in postpartum recovery. Its leaves contain tannins, which are thought to have astringent properties, and it has been used in folk remedies as a vaginal wash or sitz bath to soothe irritation and promote healing of the perineal area after childbirth.

However, the scientific evidence supporting these uses is limited. Most of the data come from anecdotal reports and traditional texts rather than controlled clinical trials. Some laboratory studies have identified anti-inflammatory and antioxidant properties in Lady’s Mantle extracts, and the astringency of tannins could theoretically tighten or tone mucosal tissues, but this has not been rigorously tested or validated in human subjects for vaginal health purposes.

In summary, Lady’s Mantle is primarily justified by tradition for supporting the vaginal body system, with little robust scientific validation to date. Its traditional use persists in herbal medicine, but modern clinical evidence is lacking, so its efficacy should be considered unproven beyond historical and anecdotal reports.
