Yellow Jessamine is a twinging vine with shinny leaves and yellow flowers that look like trumpets with five rounded petals. It blooms around here about the middle of February. It can be found in dry or wet woods and thickets.
Years ago, root preparations were used to depress the central nervous system (CNS). It deadened pain and decreased spasms. It was also used externally as a folk treatment for skin cancer.
HOWEVER!!!! THE PLANT IS DEADLY POISON. Eating a single flower could kill a child or small person. Decrease of feeling would start in your legs and go up. It kills nerve cells, including the ones that make your heart beat and the ones that allow you to breathe.
My mother told me once that they placed the vines around the outside edges of the rooms in their house to kill mice at night. In the morning they would pick up the dead mice and throw them outside.
