Berchemia scandens, commonly called supplejack, Alabama supplejack, Carolina supplejack, and American rattan,[2][3] is a woody vine in the buckthorn family native to the southeastern United States.

[4] It is found in a wide variety of habitats, including swamps, bottomlands, streambanks, moist to dry upland forests, woodlands, glades, and prairies over calcareous rock or sediment.

[2] It is a woody vine, with older stems reaching 18 cm in diameter.

[5] The Houma people used a decoction of the aerial parts of the vine for impotency.

Other Native Americans used the plant as a blood purifier and the ashes of the vine to treat coughs.
