--><p>The mature reddish roots of <i>Eriogonum alatum</i> can be distinctively chambered. The Navajo (Diné) people consider the species to be a “life medicine” (L. C. Wyman and S. K. Harris 1951), using a mixture of shredded roots and water primarily to treat internal ailments. The species is used also as a ceremonial medicine (P. A. Vestal 1952). The Zuni use it as an emetic for stomachaches (S. Camazine and R. A. Bye 1980).</p>
