Marshmallow (Althaea officinalis) is a plant from the Malvaceae family, traditionally used in herbal medicine to treat respiratory, digestive, and skin inflammation issues. Native to damp regions of Europe and Western Asia, its roots contain mucilage, which provides soothing and anti-inflammatory properties. Marshmallow is often used in teas or topical treatments to relieve sore throats, coughs, and skin irritations.
