Arabinogalactan Polysaccharides

Traditional

Mechanism of Action

Form a protective hydrophilic gel layer on irritated mucous membranes of the oropharynx and upper respiratory tract, reducing friction, preventing desiccation, and providing a physical barrier against further irritant exposure. May modulate toll-like receptor 4 (TLR4) signaling in intestinal immune cells, promoting balanced innate immune responses. The viscous coating physically inhibits viral and bacterial adhesion to epithelial receptor sites.

Research Notes

Linden / Lime BlossomWestern

The demulcent mechanism of linden polysaccharides is well-established pharmacologically and underpins the EMA traditional use approval for upper respiratory catarrh. Clinical evidence is limited to traditional use assessment rather than prospective RCTs; however, the physicochemical mechanism is robust and the clinical benefit for soothing throat irritation is consistent with the properties of mucilaginous herbs broadly validated across botanical families.
