Carapichea ipecacuanha is a species of flowering plant in the family Rubiaceae. It is native to Costa Rica, Nicaragua, Panama, Colombia, and Brazil. Its common name, ipecacuanha, is derived from the Tupi ipega'kwãi, or "road-side sick-making plant". The plant has been discussed under a variety of synonyms over the years by various botanists. The roots were used to make syrup of ipecac, a powerful emetic, a longtime over-the-counter medicine no longer approved for medical use in the West for lack of evidence of safety and efficacy. An example of emetic compound from the roots is emetine.
