Legends, Myths and Stories

The earth lodges of the southern Plains Indians, the Wichitas, the nations and tribes of the Missouri had timbers laid upon the rafters, willow poles were laid on these timbers and a thatch of dry grass upon these poles.  A covering of earth was built up about the walls and over the roof to a total thickness of about 2 ft., making, when complete a dome-shaped structure.  All structural timbers and poles were fastened by tying with ropes of rawhide or of basswood or elm fiber.

When crops failed or long severe winters exhausted food supplies, Native Americans and pioneers alike, were often saved from starvation by the use of sweet or slippery elm bark.  This emergency source of food had the advantage of being available when all other sources of food failed.  The use of the bark as food spread with the early colonies until the day when the vast forests were converted into farm lands.  The slippery elm was plentiful in the forests then.

In 1853, Pierre Lacour, a manufacturer of liquors, bitters, vinegar, etc, states that,  “The mucilage of slippery elm bark is used by some for the appearance of age to liquors.  Only 1 oz. of mucilage is used for each 2 gallons of liquor.  When too much is added, it will be observed floating in the form of flaky particles, which will have to be removed by straining.”

Culpeper states that “The roots of the Elm, boiled for a long time in water, and the fat arising on top thereof, being clean skimmed off, and the place anointed therewith that is grown bald, and the hair fallen away, will quickly restore them again.”

Formulas or Dosages

Infusion:  steep 2 oz. or more of inner bark in 1 qt. water for an hour or longer.  Take 1 tsp. every 30 minutes.  Sweeten with honey a dash of cinnamon, or syrup if desired.

Decoction:  add 1 heaping tbsp. inner bark to 1 pint boiling water and let stand for 1 hour.  Bring to a boil and simmer for a few minutes.  Then let stand for another hour, boil and simmer again.

Tea: Three tbsp. of inner bark in a cup of hot water makes a thick, mucilaginous tea.

Poultice: stir ground slippery elm bark in water or any strong herb tea, to the consistency of a thick paste.  It is excellent for inflamed sores.  Or mix 1/3 part lobelia with 2/3 part slippery elm.  Good for blood poisoning, boils, and abscesses.

Poultice: Make a regular slippery elm poultice; mix a yeast cake with warm water and add to the slippery elm.   This poultice will bring boils and abscesses to a head and keep gangrene from developing.

Warning

Due to its depletion from Dutch Elm Disease, the American elm should be protected against widespread use of its bark.  The bark cannot be used without disfiguring or killing a noble tree.  Whole trees are stripped of their bark for commercial use, then the tree dies.

Care should be taken with severe lung congestion or edema.  Consult medical advise.
