Plant Guide

Uses

Ethnobotanic: The pods of this mesquite provided an important food to the Maricopa, Pima, Haulapais, and other tribes of the Southwest and are still very important today. The pods or the seeds alone are ground in a mortar or the seeds are sometimes parched and afterwards ground into a meal that is very nourishing. This meal is eaten as is, used to sweeten other seed mixtures, or made into bread. Traditionally a drink was prepared from the beans by pounding them in a stone mortar, mixing cold water with the flour, and the product was strained and drank. The black gum from the mesquite was an important medicine to the Pima. It was boiled with a little water and applied to sore lips and gums, chapped fingers, and taken internally to cleanse the system. Mesquite leaves were pounded and boiled and placed on the eyes of Pima individuals as a treatment for pink eye. The Pima used black gum in a concoction to dye gray hair black. Industrial: The wood is used for fence posts and the heartwood takes a fine polish. The flowers are used as a source of bee food in the honey industry. Wildlife: Mesquite is an important tree to wildlife. The seeds are eaten by jackrabbits, Gambel quail, songbirds, various small mammals, and domestic livestock. Western chipmunks, ground squirrels, pocket mice, and various species of kangaroo and wood rats consume the foliage. Different birds also nest in the tree's canopy.
