This tuberous vine is best known for its steroid-like saponins which can be chemically converted to progesterone contraceptives and cortisone.  The root is edible and considered a homeopathic remedy for a variety of symptoms.  Its most attractive feature is its delicate, heart-shaped, shiny leaves which are distinctively veined, giving the leaf a puckered look.  Climbs by twining and will grow up tree branches, tall herbaceous plants or whatever it can find.  Native to bogs, swamps, marshes, river and lake margins, woods and thickets.   Must have both male and female plants to get seed.
