| "An acidic heteropolysaccharide isolated from the mucilage of the roots of the marsh mallow (Althaea officinalis L., var. Rhobusta) via its insoluble barium salt contained d-galactose, l-rhamnose, d-glucuronic acid, and d-galacturonic acid in the molar ratios 1.2:1.0:1.0:1.0. It was homogenous on free-boundary electrophoresis and in the anlytical ultracentrifuge, and it had w = 26,700, n = 23,900. Partial acid hydrolysis and analyses of the methylated and the methylated, carboxyl-reduced polysaccharide indicated that the polymer backbone is composed of (1→4)-linked d-galactopyranuronic acid and (1→2)-linked l-rhamnopyranose units in the ratio of 1:1. Each d-galacturonic unit carries a single β-d-glucopyranuronic residue linked to C-3, and each l-rhamnopyranose unit carries d-galactopyranose residues, mainly as non-reducing terminals linked to C-4. A smal number of presumably short chains of (1→4)-linked d-galactopyranose units are also involved in branching." \\ | "An acidic heteropolysaccharide isolated from the mucilage of the roots of the marsh mallow (Althaea officinalis L., var.

| | "Aqueous extracts of the roots stimulated phagocytosis, and the release of oxygen radicals and leukotrienes from human neutrophils in vitro. The aqueous extract also induced the release of cytokines, interleukin-6 and tumour necrosis factor from human monocytes in vitro, thereby exhibiting anti-inflammatory and immune-stimulant activity." \\ |

| Marshmallow root (Althaeae radix) infusions are taken orally for cough, inflammations of the mucosa of mouth, throatt and stomach. Infusions of the leaves (Althaeae folium) or syrup (Syrupus Althaeae) are used to treat dry cough and inflammation of the respiratory tract. "Commercially, only the roots are used, while leaves and flowers are popular for self-medication... The polysaccharides form a protective film over inflamed mucosal tissues and thus reduce irritation... The well-known marshmallow sweets were once made from root extracts of this plant." \\ | Marshmallow root (Althaeae radix) infusions are taken orally for cough, inflammations of the mucosa of mouth, throatt and stomach.
