Our Health4All Marshmallow Root capsules have been formulated to provide 500mg Marshmallow root which has been extensively studied to examine its effects on soothing the mucosal membranes found in digestive and respiratory tracts. Marshmallow root (Althaea Officinalis) contains a starchy carbohydrate substance called mucilage. When it's mixed with water it swells and forms a gel.
