Hydrastis canadensis L.
Golden Seal

At one time, this plant grew wild in the woods of eastern North America but its medicinal use as a "tonic" led almost to extermination from ruthless collection of the rhizomes. The plant may also be found in cultivation.

Schwarz et al. (1957) list the plant as an irritant but give no clinical or other details.
