|discussion=<p><i>Aristolochia macrophylla</i> has possibly escaped from cultivation in Connecticut, Maryland, Massachusetts, New Jersey, New York, and Vermont; these are not documented.</p><!--
--><p>The name <i>Aristolochia</i> durior Hill has been misapplied to this species.</p><!--
--><p>The Cherokee applied decoctions made from the roots of <i>Aristolochia macrophylla</i> directly to feet and legs to alleviate swelling; they ingested a compound infusion of "stalk chips" for yellowish urine (D. E. Moerman 1986).</p><!--
--><p>The leaves of <i>Aristolochia macrophylla</i> are eaten by larvae of the eastern pipe-vine swallowtail butterfly, Battus philenor philenor (Linnaeus) (W. H. Howe 1975).</p>
