Marshmallow leaf is derived from the marshmallow plant, known scientifically as Althaea officinalis. This perennial herb is native to Europe, Western Asia, and North Africa but has also been naturalized in North America. The marshmallow plant thrives in damp, marshy environments, which is how it got its name. The leaves are soft and velvety to the touch, typically light green in color, and have a slightly serrated edge. They are often heart-shaped or oval with a pointed tip. Marshmallow leaves have been used for centuries in traditional medicine due to their soothing and anti-inflammatory properties. They are commonly utilized in herbal teas, tinctures, and poultices to help alleviate respiratory and digestive issues, as well as to soothe irritated skin. The leaves contain mucilage, a gelatinous substance that provides a protective coating and helps to reduce inflammation.
