It climbs through woodland edges and hedgerows and produces heart-shaped leaves with slender, winding stems. The root and rhizome are the parts most often dried and used in traditional herbal preparations.

It has traditionally been prepared as decoctions, tinctures, and powdered root in formulas focused on cramping and spasm support. Wild yam should not be confused with edible cultivated yams sold as food.
