Marshmallow (Althaea officinalis) has a long-standing history in traditional herbal medicine, particularly in European and Middle Eastern cultures. Its roots and leaves have been used for their soothing, demulcent (mucilage-forming) properties. In the context of leucorrhea—a condition characterized by abnormal vaginal discharge—marshmallow was commonly recommended in traditional systems such as Unani and Ayurveda. The rationale was that marshmallow's mucilage could soothe irritated mucous membranes and potentially reduce inflammation or discomfort associated with vaginal discharge.

Despite this traditional use, there is a lack of robust scientific evidence supporting marshmallow's efficacy in treating leucorrhea. Most modern clinical studies and pharmacological evaluations of marshmallow have focused on its effects on the respiratory and digestive tracts, not specifically on gynecological conditions. The evidence for its use in leucorrhea remains anecdotal or based on historical texts. No significant randomized controlled trials or observational studies have validated its direct benefit for this condition. Therefore, while marshmallow's use is justified by tradition, the scientific validation for its application in leucorrhea is minimal.
