|discussion=<p>Inflorescences of <i>Aristolochia serpentaria</i> 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 <i>Aristolochia</i> leaves on which to lay their eggs.</p><!--
--><p>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.</p><!--
--><p>Several Native American tribes used <i>Aristolochia serpentaria</i> 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).</p>
