Belladonna berries look very much like blueberries. They’re shiny black, about half an inch in size, and they’re sweet. The berries are highly toxic. They cause delirium and hallucinations, and they disrupt the body’s ability to regulate its sweating, heart rate, and breathing. Eventually, seizures and cardiovascular failure will occur. Early humans made poisonous arrows using belladonna. In an adult, fifteen to twenty berries are enough to kill you. A child could die from two or three.
