Osmorhiza occidentalis is a species of flowering plant in the carrot family known by the common name western sweetroot. It is native to much of western North America, where it grows in wooded and forested areas. It is an erect perennial herb up sometimes exceeding one meter tall. The green leaves have blades up to 20 centimeters long which are divided into toothed and irregularly cut leaflets. The blade is borne on a long petiole. The flower cluster is a compound umbel of many tiny yellowish flowers at the tip of a stemlike peduncle. The fruit is elongated and narrow, up to 2.2 centimeters long. Many Native American groups used this plant for a great variety of medicinal purposes.
