Common Marsh-Mallow

<em>Althaea officinalis</em>, the common marsh mallow, is a tall perennial herb in the family Malvaceae, native to Europe and western Asia and now widely distributed across Africa, Asia, Europe, North America, and South America. It is classified as Near Threatened on the IUCN Red List. This species typically grows in saltmarshes, brackish ditches, damp meadows, and coastal habitats, and is also cultivated in gardens for its ornamental and medicinal properties. Common marsh mallow produces pale pink, five-petalled flowers and lobed, velvety leaves covered in soft hairs. It has a long history of medicinal use, with roots, leaves, and flowers employed to soothe mucous membranes and treat respiratory and digestive ailments. The original marshmallow confection was prepared from the mucilaginous root extract of this species. It grows in a range of biome types including grasslands, wetlands, and forest edges. Habitat loss, particularly of coastal wetlands, represents the primary pressure on populations across its native range.
