It is said ten drops of croton, taken internally, will have fatal results. If allowed to come into contact with the skin, croton oil causes blistering and painful skin irritation which can last up to three weeks. When taken internally, croton oil produces burning pain in the mouth and stomach, bloody diarrhea, violent purging, tachycardia, coma, and death.
