Erythrina arborea Small[2] Erythrina herbacea, commonly known as the coral bean, Cherokee bean, Mamou plant in South Louisiana, red cardinal or cardinal spear, is a flowering shrub or small tree found throughout the southeastern United States and northeastern Mexico;[2] it has also been reported from parts of Central America and, as an introduced species, from Pakistan.

[7] Toxic alkaloids, including erysopine, erysothiopine, erysothiovine, erysovine, erythrinine, erythroresin, coralin, erythric acid, and hypaphorine,[8] are found throughout the plant.

[citation needed] Erythrina herbacea can be readily grown in gardens within its natural range.

Although its use in gardens is not particularly common, it is popular among those who do grow it as a source of early season color, for its hardiness (USDA Zones 7-10), and because it attracts hummingbirds.

Creek women used an infusion of the root for bowel pain; the Choctaw used a decoction of the leaves as a general tonic; the Seminole used an extract of the roots for digestive problems, and extracts of the seeds, or of the inner bark, as an external rub for rheumatic disorders.
