Varieties 2 (2 in the flora). According to N. J. Turner et al. (1980), plants of the narrow-leaved phase (var. angustifolum) were used for colds, tuberculosis, and other lung ailments, and to treat infected cuts and sores (a decoction of roots and stems). V. F. Ray (1933) reported that a decoction of roots of such plants was taken for diarrhea. E. V. Steedman (1930) said that they were taken for stomachaches, used in steambaths to treat aching joints and muscles, and had a role in a purifying ceremony held in sweatlodges. Steedman also indicated that a strong decoction was taken by the Thompson Indians to treat syphilis. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Eriogonum cronquistii is known only from the western slope and summit of Bull Mountain, Henry Mountains, Garfield County. The Bureau of Land Management considers it a “sensitive” species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
