Species of flowering plant

Silphium terebinthinaceum is a member of the Asteraceae, a family that includes sunflowers, and is commonly referred to as prairie dock or prairie rosinweed. It is native to central and eastern North America. "Rosinweed" became one of the plant's common names due to the fact that upon injury, resin flows from the wound, giving the plant a sweet smell. Tea brewed from the roots of the prairie dock have a variety of medical applications in Native American culture. The smoke from this plant has also been used as a treatment for congestion and rheumatism.
