Our slippery elm bark powder (from ulmmus rubra) is 100% inner bark that is a safe and gentle herb and is allergen free. It is very rich in mucilage, a complex mixture of polysaccharides that form a soothing gelatinous fiber when water is added. It is suitable for sensitive or inflamed mucous membrane linings in the digestive system. It is recommended for soothing gastric diseases such as Irritable Bowel Disorder (IBD). It has several beneficial effects on digestion: 1) it reduces bowel transit time; 2) it absorbs toxins from the bowel; 3) increases fecal bulk and dilutes stool materials thereby reducing stool contact with the intestinal mucosa 4) it enhances beneficial bacteria in the gut. The bark has noted anti-inflammatory activity and because the mucilage resists digestion by stomachs acids and enzymes, it maintains its soothing action throughout the entire digestive system.
