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