Medicine The plant is highly toxic, causing nausea and vomiting. If the poison is not evacuated, cold sweat and vertigo appears. Respiration slows, cardiac rhythm and blood pressure falls, eventually leading to death.It is used externally by several Native American nations for external treatment. Although is rarely ever used modern herbalism due to its concentration of various alkaloids, it has been used in the past against high blood pressure and rapid heartbeat. The root contains even higher concentrations than the aerial parts.Plants for a Future: Veratrum virideThe plant was used by some tribes to elect a new leader.
