Early pioneers stuffed this plant in their mattresses to repel fleas and bedbugs. The plant was well known to yeild a red dye among the White Mountain Apache, Zuni, and Cherokee, and this knowledge was passed to european colonists. Modern dye experts have produced a wide array of colors such as reddish-brown, rusty red, oragnge-red, bright orange, gold, yellow, and even green. Both Lakota and Zuni also made a red drink from the plant. Plant tops were harvested and dried for later use as a tea to "strengthen the blood." The Zuni made a beverage of the plant, until the introduction of coffee by traders1.
