Other info. - This species can be found throughout Missouri. The plant is very easy to ID when in flower or fruit because both are distinctive.
Steyermark breaks this species down into three forms, I won't go into those here as they are no longer valid.
Medicinally, this species is an expectorant, an emetic, and an astringent. Natives used the caudex in many forms to cure many ailments. Smoke from roasting seeds was used to revive the unconscious by being blown into the nostrils of the patient.
