Veronicastrum virginicum (Culver's root, Culver's-root, Culverpsyic, Culver's physic, Bowman's root, blackroot; syn. Leptandra virginica (L.) Nutt., Veronica virginica L.) is a wildflower native to the United States.
Veronicastrum virginicum is an erect perennial herb that grows 80–200 cm in height. The leaves are serrated and arranged in whorls of 3-7 around the stem. The inflorescence is erect with slender and spike-like racemes. The stamens are crowded and protrude in a brush-like fashion perpendicular to the raceme . The corollas are white and are roughly 2 mm. in length. These plants flower from mid-summer to early fall.
Culver's root is frequently found in wet to wet-mesic prairies and sometimes moist upland sites.
Culver's root has been used medicinally for liver disorders and constipation. It is a long-time American doctors' remedy for liver congestion with accompanying constipation. It is sometimes considered when compounding a formula for the liver, gallbladder, to treat constipation, colitis, gallstones and hepatitis.
