About
Amorpha fruticosa is a species of flowering plant in the legume family Fabaceae, known by several common names, including desert false indigo, false indigo-bush, and bastard indigobush. It is native to North America.
Safety
6'-O-β-D-glucopyranosyl-12a-hydroxydalpanol, a rotenoid, can be found in the fruits of A. fruticosa. Several members of the amorfrutin class of compounds have been isolated from the fruits. Amorfrutins as well as other secondary metabolites from A. fruticosa have displayed favorable bioactivities counteracting diabetes and the metabolic syndrome.
Where it grows
The native range extends through much of the United States and south into Mexico. Its native habitats include stream and pond edges, open woods, roadsides and canyons.
