Lady's Mantle (Alchemilla vulgaris) has a long history of traditional use in European herbal medicine, particularly for women's reproductive health concerns. Historically, it has been used to treat a variety of gynecological conditions, including heavy menstrual bleeding, menstrual cramps, and as a topical wash for vaginal irritation or inflammation. The tannins and astringent compounds in Lady's Mantle are believed to help tighten and tone mucous membranes, which may explain its traditional application in cases of vaginitis or vaginal discharge.

However, there is a lack of robust scientific evidence or clinical trials specifically evaluating the efficacy of Lady's Mantle for treating vaginitis. Most of the support for its use in this context is anecdotal or based on historical texts and the general astringent properties of the plant. Modern herbal references may still mention Lady's Mantle for vaginal health, but this is primarily as a continuation of traditional practice rather than evidence-based medicine. As such, while Lady's Mantle is traditionally used to support or treat vaginitis, there is minimal scientific validation for this application.
