[Wikipedia] Range, Toxicity, Habitat, Medicine: Veratrum viride, known as Indian poke, corn-lily, Indian hellebore, false hellebore, green false hellebore,[2] or giant false-helleborine,[3] is a species of Veratrum native to eastern and western (but not central) North America.[4][2][5] It is extremely toxic, and is considered a pest plant by farmers with livestock. Veratrum viride var. viride is found in eastern North America. It is differentiated by the erect or spreading side branches of the inflorescence. It is found in wet soils in meadows, sunny streambanks, and open forests, occurring from sea level in the north of its range up to 1,600 metres (5,200 ft) in the southeast and 2,500 metres (8,200 ft) in the southwest.[4][6][7] Medicine The plant is highly toxic, causing nausea and vomiting. If the poison is not evacuated, cold sweat and vertigo appear. Respiration slows, while cardiac rhythm and blood pressure fall.[11] The toxic effects of veratrum alkaloids[11] are directly induced by antagonism of adrenergic receptors. It is used externally by several Native American nations. Although is rarely ever used in modern herbalism due to its concentration of various alkaloids, it has been used in the past against high blood pressure and rapid heartbeat; a standardized extract of V. viride alkaloids known as alkavervir was used in the 1950s and 1960s as an antihypertensive.[12][13] The root contains even higher concentrations than the aerial parts.[14] (contributed by Mary Ann Machi)
