Goldenseal (Hydrastis canadensis)

Goldenseal (Hydrastis canadensis) is notable for its yellow, knobby rhizomes. This perennial herb thrives in the woodlands of southeastern Canada and the eastern United States, but it is increasingly rare in the wild. It bears red, raspberry-like berries that are visually appealing but not edible. The plant’s roots are useful for producing a yellow dye and can also serve as an insecticide. It’s important to note that all parts of Goldenseal are toxic if consumed in large quantities.
