The term 'Former Poisoning Treatment' is referring to the drug IPECAC, which was commonly used in the past to induce vomiting after a person had ingested a poisonous substance. IPECAC was an effective treatment for poisoning, as it would help to expel the poison from the body before it could cause any serious harm. However, due to its potential side effects, it is no longer recommended as a first-line treatment for poisoning.
