Mallow (Malva sylvestris and related species) has traditionally been used in folk medicine for various inflammatory conditions, including swollen glands or lymph nodes. Historical herbal texts and ethnobotanical sources from Europe and the Mediterranean describe its use as a soothing and anti-inflammatory remedy, often applied as poultices or consumed as teas to alleviate swellings and inflammations, which may include lymphatic swellings. The mucilage content in mallow is thought to provide a demulcent effect, soothing irritated tissues. However, there is very limited modern scientific evidence specifically supporting mallow’s efficacy for treating swollen lymph nodes or glandular issues. Most contemporary research on mallow focuses on its general anti-inflammatory and antioxidant properties rather than specific action on the lymphatic system or swollen glands. Therefore, while there is a traditional basis for its use in this context, scientific validation is lacking, and the evidence remains anecdotal. In summary, mallow’s use for swollen glands is justified primarily by tradition, with a low level of supporting evidence. Individuals should consult healthcare professionals for persistent or unexplained lymphatic swelling, as this can be a sign of underlying health issues requiring medical attention.
