Historically, the plant has been used by Indigenous peoples for many purposes. Raw and cooked seeds were eaten, and leaves were mixed with those of other plants and boiled with small game animals. Many tribes used the wood and bark for making tools and furniture. Noted for the strength of its wood, it was often used for making digging sticks, spears, arrows, bows, harpoons and nails. The wood, like with many other plants, was often hardened with fire and was then polished using horsetail.
Comox natives use oceanspray when flowering as an indicator of the best time to dig for butter clams.
