20. Purging croton

The purging croton's interesting name is thought to come from the Greek word tiglos, meaning "diarrhea", which may be thanks to the toxic compounds that cause "purging" bowel movements in humans. Humans were able to use this to their advantage, however, by poisoning arrow tips with the bark of Croton tiglium and using the toxic seeds to kill and catch fish.
