English ivy secretions, particularly from its adventitious roots, contain a high-strength natural adhesive composed of rhamnogalacturonan I polysaccharides (complex sugars) and specialized glycoproteins. This mucilage matrix forms an exceptionally durable bond that hardens as it dries, allowing ivy to attach firmly to vertical surfaces like walls and trees. [1, 2, 3, 4]
Beyond its gripping ability, the interaction between polysaccharides and ivy encompasses several distinct fields: [1]
1. Natural Bioadhesives
The nanocomposite adhesive secreted by English ivy (Hedera helix) root hairs contains nanoparticles in a polysaccharide-rich fluid. Studies identified the adhesive as primarily consisting of debranched rhamnogalacturonan I polysaccharides with molecular weights ranging from 50–200 kDa. This natural mechanism is currently being studied to inspire synthetic, wet-tolerant, and non-toxic bioadhesives for construction and marine engineering. [1, 2, 3]
2. Respiratory & Throat Relief
Polysaccharides function as highly effective demulcents. When combined with English Ivy (which contains other active components like saponins) in cough syrups, these mucilaginous polysaccharides coat and soothe the mucosal lining of the respiratory tract. A widely used product utilizing this combination is 
3. Skin and Cosmetic Applications
The nanoparticle-polysaccharide complex isolated from ivy extract is also being evaluated for cosmetic and dermatological uses. Because natural plant polysaccharides act as a barrier and contain hydrating and antioxidant properties, ivy extract (often paired with other lipids) is used in formulations meant to soothe, protect, and moisturize sensitive or irritated skin
3. House Insulation and Air Quality
When kept as a “house plant” (either growing on the facade or indoors), ivy acts as a natural shield. Research by the Royal Horticultural Society (RHS) shows that the thick canopy of ivy leaves creates a microclimate that keeps a house cooler in summer and warmer in winter. Furthermore, the plant’s metabolic processes help filter airborne pollutants, improving indoor and outdoor air quality. [1, 2, 3, 4, 5]
