Eriogonum cernuum

Ethnobotany. According to the book "The Ethnobotany of the Kayentah Navaho" (Wyman, Leland C. and Stuart K. Harris. The University of New Mexico Press. 1951), Eriogonum cernuum was used for skin rashes and for kidney diseases. The seeds were also made into a mush for food.

According to the book "The Ethnobotany of the Ramah Navaho" (Vestal, Paul A., 1952, Papers of the Peabody Museum of American Archaeology and Ethnology), Eriogonum cernuum was used as a poultice of chewed leaves applied to red ant bite.

According to the book "CRC World Dictionnary of Medicinal and Poisonous Plants" (Umberto Quattrocchi), Eriogonum cernuum was used also as a tonic and a antiseptic.  

With the Gosiute Peoples of Nevada and Utah, Eriogonum cernuum is called "Oi'tcu-mo",  from Oi'tcu for bird and Mo'a for leg.

In the Bear Medicine of the Tewa (Pueblos) of New Mexico,  Eriogonum cernuum - "poe unipi" -  is used as a birth plant: a decoction of the plant is given after the birth. The other species used by the midwives are the following: Gilia rigidula; Phoradendron juniperum; Gutierrezia sarothrae; Croton texensis; Aquilegia caerulea; Dyssodia papposa; Euphorbia serpyllifolia; Mentzelia pumila; Asclepias latifolia; Malva parviflora.

In "Navajo Indian Medical Ethnobotany" (University of New-Mexico Bulletin. 1941) authored by Leland C. Wyman and Stuart K. Harris we find the following: Diseases (especially kidney and bladder disease, sudoresis, and stomach distress) attributed to swallowing a red ant (in food or water), or to other types of "red ant infection," may be treated by Red Ant Way; hence plants used for these conditions may pertain to this Chant Way. Decoctions or infusions of the plants are taken internally and are said to "kill the ant." Itching and sores caused by red ant bites are treated by applying decoctions or infusions as lotions, or by chewing the leaves of the plants and applying them as poultices. The plants may be designated by the Navajo names "red ant medicine" {1}  "red ant killer" {2}  "red ant food" {3}  or included in the Navajo family or form genus "red ant decoction" {4}. See diuretics.
