The roots of the ipecac plant contain emetine and cephaeline, which are alkaloids responsible for its emetic action. Ipecac syrup is a commonly used preparation to treat cases of poisoning. It acts by irritating the stomach lining and stimulating the brain's chemoreceptor trigger zone, leading to vomiting (5 ).

It works by stimulating the vomiting center in the brain (6 ). Lobelia is used in traditional medicine to clear the stomach of toxins and treat respiratory conditions. It should be used with caution due to its potent effects and potential toxicity at high doses.
