Possible commercial uses

Rubber rabbitbrush was considered as a source of rubber as early as 1904.[16] 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 1987.[17] Currently the University of Nevada is conducting research on possible of uses of rubber rabbitbrush for biomaterial and bioenergy uses.[18] One possible commercial use of rubber rabbitbrush would be as a source for hypoallergenic rubber for use in products designed for people with latex allergies.[19]" (Wikipedia)
