Slippery Elm Bark
Slippery Elm Bark
Snapshot
Slippery Elm Bark is an herbaceous supplement derived from the inner bark of Ulmus rubra, rich in mucilage and phytochemicals that soothe mucous membranes, support digestive health, and aid in wound healing.
What is Slippery Elm Bark?
Slippery Elm Bark is the inner bark of the North American Elm tree (Ulmus rubra). When hydrated, its high mucilage content forms a gel‑like substance that coats and calms irritated tissues in the digestive and respiratory tracts.
Where It Comes From
The bark is harvested from mature elm trees in spring or early summer, carefully peeled to access the inner layers, then gently dried and milled into a fine, light‑brown powder or prepared as extract tinctures.
Key Nutrients & Compounds
Provides soluble mucilage polysaccharides, tannins, flavonoids, and small amounts of phenolic acids, all contributing to its demulcent, anti‑inflammatory, and antioxidant activities.
Health Benefits
Slippery Elm Bark soothes gastrointestinal irritation by forming a protective mucilage layer; supports bowel regularity and eases occasional constipation; calms sore throat and cough via mucosal coating; and promotes topical wound healing when applied as a poultice.
Recommended Dosage
Typical oral dosing is 400–600 mg of powdered bark two to three times daily, mixed with water to form a gel. For throat and cough support, 1 teaspoon (approximately 5 g) mixed in warm water can be sipped as needed.
How to Use It
Stir the powder into water, juice, or herbal tea and consume promptly to benefit from mucilage. For topical use, blend with a small amount of water into a paste and apply directly to minor skin irritations or wounds.
Who Should Use It?
Individuals with mild digestive discomfort, heartburn, sore throat, or dry cough may find relief. Those seeking natural mucosal support before or after exercise, speaking engagements, or travel can also benefit.
Possible Interactions or Cautions
Generally well tolerated. Separate administration from prescription medications by at least one hour to avoid reduced absorption. Discontinue use and consult a healthcare provider if symptoms persist or allergic reactions occur.
Final Thoughts
Slippery Elm Bark is a time‑honored herbal remedy for soothing and protecting mucous membranes throughout the body. Its simple, mucilage‑based mechanism makes it a versatile adjunct for digestive and respiratory comfort.
