Uses

The Zuni people use the blossoms ''bigelovii'' variety of the ''nauseosa'' subspecies to make a yellow dye. They use the stems to make baskets. The Navajo also made a yellow dye from some of the flower heads.

Possible commercial uses

Rubber rabbitbrush was considered as a source of rubber as early as 1904. Several studies have been conducted on the possible use of rubber rabbitbrush as a source of rubber including ones during World Wars I and II, and in 1987. Between 2005 and 2008, the
