Ipecacuanha, also known as ipecac, is a powerful emetic plant that has been used for centuries in traditional medicine. However, due to its toxicity and potential side effects, it is mainly used in modern medicine as a source of the emetic drug emetine. Some common synonyms for ipecacuanha include Carapichea ipecacuanha, Cephaelis ipecacuanha, and Psychotria ipecacuanha. In Brazil and other parts of South America, ipecacuanha is also known as poaya, pega-pega, and rioho. It is important to note that while ipecacuanha has medical benefits, it can be dangerous if used improperly and should only be taken under the guidance of a healthcare professional.
