Senna covesii
Fabaceae
Arizona, Nevada, California, and New Mexico (elevation: 1,000 to 4,000 feet). Typically grows on wash embankments and gravely hillsides.
April to October
Desert senna is primarily used medicinally as a stimulant and strong laxative.
It is used to soften stool and induce bowel movements. The leaves have the largest quantities of medicinal compounds but don’t have the polysaccharide-starches that are present in the pods, which makes the effects more severe.
