Answer:
The word emetic is from the root word emesis, which means vomit. An emetic is something which will induce vomiting. A common emetic is syrup of ipecac, which is occasionally used to induce vomiting if a patient is suspected of having ingested some kind of poison. Syrup of ipecac has fallen out of favor over the last several years because it was not always effective at emptying the stomach, and did little to remove material which had already moved into the rest of the digestive system.
