marshmallow root
Marshmallow root (Althaea officinalis L.) is a medicinal plant containing mucilaginous polysaccharides that form a protective film on mucous membranes. The root extract has demonstrated anti-inflammatory, anti-oxidative, and cytoprotective effects on epithelial cells and macrophages in laboratory studies. Traditionally used for centuries to treat respiratory irritation, cough, and mild gastrointestinal discomfort.
Lab Notes — Research Studies
01 Anti-inflammatory and Anti-oxidative Effects of Phytohustil and Root Extract of Althaea officinalis L. on Macrophages in vitro
Marshmallow root extract protected human macrophages against oxidative stress, reduced inflammatory cytokines (IL-6, IL-8, TNF-α), and decreased ROS production while maintaining cell viability and migratory capacity.
View Study ((PubMed))02 Aqueous extracts and polysaccharides from Marshmallow roots: Cellular internalisation and stimulation of cell physiology of human epithelial cells in vitro
Marshmallow root polysaccharides stimulated epithelial cell viability and were internalized into cells, while forming bioadhesive layers on fibroblasts, with gene expression analysis showing up-regulation of cell adhesion proteins and growth regulators.
View Study ((PubMed))03 Phytochemical Characterization of Low Molecular Weight Constituents from Marshmallow Roots and Inhibiting Effects of the Aqueous Extract on Human Hyaluronidase-1
Marshmallow root aqueous extract demonstrated inhibitory effects on human hyaluronidase-1 enzyme, which may contribute to its anti-inflammatory properties and mucous membrane protective effects.
