Althea Officinalis, or Marshmallow root, is high in starch and mucilagenous polysaccharides, which form a protective gel, along with flavonoids and anthocyanidins. This protective layer over the mucous membranes and skin effectively soothes irritation and relieves inflammation. The root of Marshmallow can promote tissue fluid generation and increase moisture in deficient skin conditions. Marshmallow is used in cosmetics for its soothing, moistening, and calming properties on the skin.
