What's in a name?
Belladonna's name is one of the most fascinating things about this plant. It's general name, or genus, Atropa comes from Greek mythology. Atropa was the name of one of the Fates who would hold the string which represented a human life and cut it, representing that person's death. This refers to Belladonna's often toxic nature. The name belladonna, comes from the Italian 'beautiful lady'. Italian women would take either the leaf of the plant and rub it in their eye, or drop a small amount of diluted berry juice into their eye, causing their pupil to dilate This would make their eyes seem more lustrous and beautiful. Thus the name. There are other rumours around the name belladonna. As the plant's toxic use was found, it became known as the plant of the devil. It was believed that the plant would take on the form of a beautiful woman and lure people to their deaths by making them eat a berry. |

Toxicity
Belladonna is an extremely dangerous plant. It's poisonous qualities have been exploited through the centuries, but we must not forget the acccidental deaths it has caused. The berries of the plant (which contain the largest amount of atropine in the plant), seeming attractive, have found their way to the mouths of many young children in Europe over the centuries, causing their deaths. Death is caused by the dampening of the respiratory system by the atropine contained within the plant, as well as the constriction of the circulatory system. Coma and death often follow. |
