I used to harvest these plants on a friends farm when I was a teenager. Get a leaf in your eye, or rub the sap in your eye, and your pupil will expand to fill the iris. You will then be unable to be in direct sunlight. Its even worse when its dried. Several people have died drinking "bush tea" made from the commercial plant. The related trees contain a large variety of alkaloid poisons, including nicotine and nor-nicotine (LD50 about 50 mg/kg). Very toxic group of plants, often in odd ways.
