There is a berry here in Peru that produces a toxin strong enough to kill a cow. The toxin affects the brain, and in people will cause convulsions and even death. It is so scary when a kid comes in having a seizure, even if you think you can treat it. With these berries, you will not always have success. I am so thankful to God that his little girl recovered. See the post below from the Diospi Suyana Hospital website.
A Quechua girl eats forbidden berries
At two o’clock, Monday afternoon a little girl was brought to the emergency room. She arrived convulsing violently and needed immediate medical treatment. After she was stabilized, she was brought to the intensive care unit for further monitoring while Dr. Heike Lindacher began to investigate just what had happened. It turns out that the little girl had eaten a handful of delicious looking, but very poisonous wild berries called Baccharis Coridifolia. When eaten, the poison acts quickly on the central nervous system and is even strong enough to kill a cow. Fortunately, she is better now.
