Lauren said that the blue-colored wine is made from the skin of the Blue Dart Tree Frog. It's a real animal with scientific name "Dendrobates azureus", which habitat is in central and south America. The skin of this frog contains alkaloid poison that causes paralysis, which can be lethal to humans as it could paralyze the heart muscles. It's called dart frog because the Amerindian tribes put the frog's poison on the tip of their darts and arrows. However, the level of toxicity of the blue frog's poison is considered mild. The most toxic dart frog is the golden-colored one, "Phyllobates terribilis", that has enough poison to kill 20 men or 10,000 mice.
