Rabbitbrush is fairly common along roadways and trails in the arid regions. Because rabbits find this plant a favorite shelter, it has been named Rabbitbrush. Indians boil the plant for yellow dye, and white man found certain species of Chrysothamnus to contain rubber.

Consideration was given to the production of rubber from Rabbitbrush during the First World War and up until the discovery of synthetic rubber.

An exotic plant probably brought into the area by vehicles, as it is found most commonly along the roadways or in cultivated fields. Once started it spreads very rapidly along the highways or in cultivated areas.

The plant is suspected to be toxic to livestock, but is rarely eaten. It is used in the treatment of asthma in humans. In addition, external use is made of it to relieve the irritation caused by Poison Ivy.
