History: Currently found around the world and considered to be one of the world’s most persistent weeds, Echinochloa crus-galli was described as being present in North America in 1759. It has been used as forage for livestock although it has been reported to accumulate toxic levels of nitrate when fed inorganic fertilizers. It is edible: its roasted seed used as a coffee substitute or cooked whole or ground into flour. E. crus-galli was used as a food staple by a number of Native American tribes in the US Southwest. The grass has also been used medicinally as a tonic to treat carbuncles, sores, warts, hemorrhages, spleen troubles and cancer.
