Virginia Snakeroot

Aristolochia serpentaria L.

Comments

provided by eFloras
Inflorescences of Aristolochia serpentaria often bear closed flowers that appear to be cleistogamous. Leaf shape varies greatly between populations, especially with regard to leaf width and size of basal lobes. This variability is especially interesting because eastern pipe-vine swallowtail butterflies, Battus philenor philenor (Linnaeus), use leaf shape as a search image when looking for Aristolochia leaves on which to lay their eggs.

The dried rhizome, called Virginia snakeroot or serpentary, is a popular herbal tonic. In small doses, it is a gastric stimulant and diuretic. Large doses can cause violent gastric distress and respiratory paralysis (J. A. Duke 1985). The rhizome contains aristolochic acid and trimethyl amine, both potential carcinogens.

Several Native American tribes used Aristolochia serpentaria for diverse medicinal purposes, including treatment of rheumatism, various pains, obstructions, worms, toothaches, sore throats, fever, sore noses, and colds, as a tonic, and mixed with saliva for snake bites (D. E. Moerman 1986).

Aristolochia serpentaria

provided by wikipedia EN

Aristolochia serpentaria is a species of perennial flowering plant in the Aristolochiaceae (birthwort) family. The species is commonly known as Virginia snakeroot and is native to eastern North America, from Connecticut to southern Michigan and south to Texas and Florida.[2][3]

Description and Ecology

They have pipe-shaped flowers and heart-shaped leaves. It is a larval host to the pipevine swallowtail and the polydamas swallowtail.[4]

Protection

Virginia snakeroot is considered an endangered species in New York, where no reports of the species were made for the century between 1895 and 1994, when it was rediscovered in the Hudson Highlands. Since then, other scattered populations have been observed in the state.[5]

The plant is also rare in Connecticut, where it is on that state's list of species of special concern.[6][7] In Michigan, its status is "Threatened."[3]
