wikipedia has this to say about its uses: The Lummi used the flowers as an antidiarrheal and the leaves as a poultice. Many other tribes used the wood and bark for making tools and furniture. Noted for the strength of its wood, it was often used for making spears, arrows, bows, harpoons and nails. The wood, like with many other plants, was often hardened with fire and was then polished using horsetail. Several Indian tribes, such as the Stl'atl'imx, would steep the berries in boiling water to use as a treatment for diarrhea, smallpox, chickenpox and as a blood tonic.
