Culver’s root (Veronicastrum virginicum)

Culver’s root (Veronicastrum virginicum) is a perennial herb in the Plantaginaceae family, native to eastern North America. It grows with upright stems, whorled leaves, and elegant white flower spikes, while the root and rhizome are the parts most often mentioned in traditional herbal use.

Traditionally, Culver’s root was used in the past as a bitter herb in digestive preparations and older cleansing formulas. It also has an important place in North American herbal history and is now widely grown as a native ornamental for pollinator-friendly gardens.

Although traditionally used as a medicinal herb, Culver’s root has potent cathartic effects and is generally not used today without professional supervision.
