Slippery Elm Bark

Slippery Elm (Ulmus fulva, U. rubra)

Slippery Elm inner bark is a must for treating gastric ulcers, as it is mucilaginous and thus will form a protective and healing poultice like layer over damaged gastric lining tissues. It’s an essential ingredient in our specially formulated blend for healing gastric ulcers, Ulcer-Ease. More info can be found about this complete treatment approach for gastric ulcers in our blog post here.

It is also anti-inflammatory and mildly astringent, so is useful as an external poultice on wounds, and as a drawing agent.  Combine with honey, marshmallow root powder and a little water and apply a layer on the inside of a leg wrap and bandage over the affected area.

It’s excellent for treating scouring, and is very safe and effective even for foals.

It helps to prevent gastric ulceration, so it is helpful to include in the feed twice daily when a horse needs to be on a long course of conventional anti-inflammatories.

Slippery elm bark is extremely costly, as it can only be harvested from a tree which is at least seven years old, only the soft inner bark can be used, and harvesting the bark can cause the tree to die.  Understandably, this invaluable tree is in very short supply and is now threatened in it’s natural habitat; so only make use of this precious herb when it is truly justifiable, otherwise Plantain or Marshmallow root are good alternatives for treating gastric ulcers.
