Greenherb supplies a premium, naturally soothing Slippery Elm Bark Extract, derived from the inner bark of Ulmus rubra Muhl., a tree native to North America with a centuries-old reputation for its remarkable mucilaginous properties. Our slippery elm extract is carefully processed from sustainably harvested organic slippery elm bark to preserve its high concentration of mucilage—a complex polysaccharide that forms a smooth, slippery gel when hydrated. This gentle, effective ingredient offers a natural solution for digestive comfort, throat soothing, and gastrointestinal wellness, providing a time-honored botanical ally for global nutraceutical, dietary supplement, and functional food markets.
We support global B2B customers with consistent quality, scalable supply, and comprehensive analytical documentation, enabling the development of effective, gentle formulations that leverage this revered demulcent herb.
Exceptionally Rich in Mucilage for Soothing Protection – Our slippery elm bark extract contains high levels of mucilage (typically 10-20%), a polysaccharide complex that forms a protective, gel-like coating when mixed with water. This unique property provides the foundation for its traditional use in soothing irritated mucous membranes throughout the digestive and respiratory tracts .
Gentle Digestive Comfort & Gut Health Support – The mucilage in slippery elm bark extract coats the lining of the esophagus, stomach, and intestines, helping to soothe occasional heartburn, gastric irritation, acid reflux, and inflammatory bowel discomfort. It provides a protective barrier that allows irritated tissues to heal naturally .
Natural Throat Soother for Coughs & Hoarseness – Slippery elm extract has been traditionally used for centuries to relieve sore throats, dry coughs, and hoarseness. The mucilage forms a smooth, soothing film over the throat's mucous membranes, reducing irritation and the urge to cough. Many slippery elm bark supplements are formulated as lozenges or throat teas for this purpose .
Supports Healthy Elimination & Gentle Detoxification – As a soluble fiber, the mucilage adds bulk to stools, supports regular bowel movements, and helps maintain healthy elimination. It acts as a gentle, non-irritating laxative for occasional constipation while also soothing inflamed bowel tissues .
May Help Manage Acid Reflux & Heartburn – Slippery elm bark extract has been shown to help reduce symptoms of gastroesophageal reflux disease (GERD) by forming a protective barrier over the esophageal lining and stomach mucosa, reducing the irritation caused by stomach acid .
Rich in Antioxidant Compounds – Beyond mucilage, slippery elm bark contains phenolic acids, tannins, and flavonoids that provide antioxidant protection and support healthy inflammatory balance, complementing its primary soothing action .
Sustainably Sourced & Available in Organic Grade – Our slippery elm bark is wild-harvested or cultivated following sustainable practices to preserve wild tree populations. We offer organic slippery elm bark powder and standardized extract powder for diverse formulation needs .

Greenherb's Slippery Elm Bark Extract captures the gentle, healing essence of a tree that has been cherished by Native American tribes and later by European settlers as one of nature's most effective demulcent herbs. The inner bark of the slippery elm tree (Ulmus rubra) has been used for centuries to soothe everything from sore throats and coughs to stomach ulcers and inflammatory bowel conditions . When mixed with water, the bark releases a thick, slippery mucilage that coats and protects irritated mucous membranes, allowing tissues to rest and heal. Unlike harsh or stimulating herbs, slippery elm works through gentle, physical action—simply forming a protective layer that soothes and calms. This makes it an ideal ingredient for individuals with sensitive digestive systems, those recovering from illness, or anyone seeking a natural, gentle approach to gastrointestinal and respiratory comfort. Our slippery elm extract powder captures this mucilage-rich profile in a concentrated, standardized form, making it the ideal choice for brands developing products in the digestive wellness, throat comfort, and gentle detoxification categories.
Botanical Source: Ulmus rubra Muhl. (Slippery Elm, Red Elm)
Used Part: Inner Bark (dried, powdered, or extracted)
Key Active Components: Mucilage (a complex polysaccharide containing galactose, rhamnose, galacturonic acid, and glucose), Phenolic Acids (caffeic acid, ferulic acid, salicylic acid), Tannins, Flavonoids (proanthocyanidins, catechins) .
Standardization: Available as whole bark powder (slippery elm bark powder), or standardized to mucilage content or total polysaccharides .
Appearance: Fine, light tan to brownish powder with characteristic mild, slightly sweet, and earthy aroma
Flavor: Mild, slightly sweet, and mucilaginous (slippery) when hydrated—pleasant and easy to formulate
Solubility: Forms a viscous, gel-like dispersion in cold or warm water; not fully soluble but provides smooth texture
Certifications: Organic slippery elm bark available (USDA Organic/EU Organic), Kosher, Halal (as required)
Our gentle process is designed to preserve the delicate mucilage polysaccharides:
Sustainable Sourcing & Authentication: Slippery elm inner bark is sustainably wild-harvested or cultivated in North America following responsible practices to ensure tree health and population regeneration. Raw material is authenticated via TLC .
Cleaning & Drying: Bark is thoroughly cleaned, sorted, and gently air-dried or low-temperature dried to preserve the mucilage structure.
Size Reduction: Dried bark is milled to a uniform particle size to optimize extraction efficiency or to produce fine powder.
Powder Processing (for whole bark powder): The dried bark is milled into a fine, consistent slippery elm bark powder using specialized equipment that prevents excessive heat generation.
Extraction & Concentration (for extract powder): For higher potency extracts, the powder undergoes gentle aqueous extraction (cold or warm water) to solubilize the mucilage polysaccharides, followed by low-temperature concentration and spray drying to produce a concentrated slippery elm extract powder .
Sieving & Standardization: The powder is sieved to achieve uniform particle size and blended for batch-to-batch consistency in viscosity, color, and polysaccharide content.
Quality Assurance: Each batch is tested for mucilage content (via viscosity or polysaccharide analysis), microbial safety, heavy metals, and moisture content.
Slippery Elm Bark Extract is valued for its gentle, physical mode of action and time-honored soothing properties:
Soothes Digestive Discomfort & Heartburn*: The mucilage forms a protective, coating layer over the mucous membranes of the esophagus, stomach, and intestines, helping to soothe occasional acid reflux, gastritis, heartburn, and inflammatory bowel discomfort.
