Slippery Elm

Slippery Elm (Ulmus rubra) is a traditional herbal remedy derived from the inner bark of the elm tree. For centuries, Indigenous peoples and early settlers used it for skin conditions and digestive issues. Today, it is celebrated as a powerful **demulcent**—a substance that turns into a gel when mixed with water, soothing and coating irritated tissues. Unlike standard vitamins found in fruits and vegetables, Slippery Elm is a unique botanical that acts like a protective balm for your insides, making it a go-to for natural gut health support.

Health Benefits & Sources

Why You Need It

  • Soothes Digestive Distress: Creates a protective coating over the mucous membranes of the esophagus and stomach.
  • Relieves Sore Throats: The mucilage content helps reduce inflammation and irritation in the throat.
  • Supports Healthy Bowel Movements: Can bulk up stool and soothe the intestinal lining, aiding in both occasional constipation and diarrhea.

Deep Dive

Slippery Elm works primarily through its high mucilage content. When you mix the powdered bark with water, it releases a thick, gel-like substance. Think of this gel as a natural barrier. If you suffer from acid reflux, the gel sits on top of stomach contents, preventing acid from splashing up into the esophagus. If you have an irritated gut, it calms inflammation, allowing the tissue to heal. It is also a mild prebiotic, feeding beneficial gut bacteria.

Natural Food Sources

Slippery Elm is not a food like an apple or carrot; it is harvested from the bark of the tree. You won't find it in the produce aisle. However, you can consume it as a powder or lozenge.

Supplementation

Slippery Elm is best taken 30 to 60 minutes before a meal. This allows the mucilage to coat the stomach and throat before food arrives. It is generally safe for short-term use (up to 8 weeks). It is safe for most adults, but due to its lack of rigorous testing, pregnant or breastfeeding women should consult a doctor first.
