Althaea officinalis (commonly called marshmallow root or marshmallow plant) is a perennial herb native to Europe, Western Asia, and North Africa. It has been used in traditional herbal medicine for centuries. The root and leaves are rich in mucilage, a gel-like substance that forms a soothing coating when mixed with water. Important: This plant is the original source of the name "marshmallow," but modern marshmallow candies generally do not contain marshmallow root. Potential health benefits. Research supports some traditional uses, but evidence is stronger for certain applications than others.
