The bark, when weathered for several years till it glows with phosphorescence in the darkness, was used to catch the spark in fire-making. The fresh inner bark was boiled and the resulting decoction was drunk as a laxative. The Omaha used to cook the inner bark with buffalo fat in rendering out the tallow. They considered that the bark gave a desirable flavor to the fat and added a preservative quality, preventing it from becoming rancid. When the rendering was finished the children always asked for the pieces of cooked bark, which they prized as titbits.
The inner bark fiber was also used for making ropes and cords.
