Slippery Elm Facts

Slippery elm (Ulmus rubra) is a tree native to North America. Its inner bark contains mucilage, a gel-like substance that swells when mixed with water. This mucilage coats and soothes tissues, particularly in the digestive tract and throat, where it helps promote comfort and resilience.

Key Benefits of Slippery Elm:

  • May support digestive comfort by soothing mucous membranes.
  • May promote resilience of the gut lining.

Why it Matters:

Mucous membrane health matters: Protective barriers in the digestive and respiratory tracts are essential for maintaining overall resilience.
