Some groups of Amazonian Indians use monkey frogs in tribal rituals. Secretions from the frog's skin are mixed with human saliva and rubbed into open wounds. Humans experience pain and gastric distress prior to feeling energized and refreshed. This induced "high" is thanks to the monkey frog's skin toxins, which include powerful hallucinogens and chemicals that affect blood pressure.
