Ipecac is a syrup once used as a poison remedy. It is derived from the dried root of a plant native to Brazil, and was used in the past to induce vomiting in cases of poisoning. The active ingredient in IPECAC is called emetine, which is a powerful emetic that stimulates the vomiting reflex. IPECAC has since been replaced by other treatments for poisoning, but it remains an important part of medical history.
