The correct option is D Poison ivy
Historically, many different substances have been used to prevent pregnancy which included honey, lemon and crocodile poop, known to work as spermicide. Apart from these, women have used the seeds from Daucus carota commonly known as wild carrot or queen anne's lace, for centuries as a contraceptive. The earliest written reference to this plant dates back to the late 5th or 4th century B.C. appearing in a work written by Hippocrates.
Poison ivy however was never used for this purpose. Poison ivy contains a substance called urushiol, which causes a rash on people who come in contact with these plants.
