Marshmallow Root
Gentle demulcent for soothing mucous membranes from the inside out.
Also known as: Althaea officinalis • White Mallow
Overview
Marshmallow root, from the Althaea officinalis plant, is a perennial herb native to Europe, Western Asia, and North Africa. Like slippery elm, it is a powerful demulcent due to its high mucilage content. It has been used for thousands of years to treat digestive, respiratory, and urinary tract issues. The mucilage forms a protective layer over inflamed mucous membranes, providing relief from irritation and promoting healing.
