What is the definition of an "antidote"?

The term "antidote" specifically refers to a substance that counteracts the effects of a poison or toxin. It is used in medical contexts to neutralize or alleviate the harmful effects of a harmful agent that has been ingested or absorbed into the body. For example, if someone has been poisoned by a particular substance, the appropriate antidote will help to reverse the effects of the poison, making this choice the most accurate definition.

While other options may seem relevant, they do not align with the specific function of an antidote. A cure for a disease refers to completely eradicating a sickness, which is broader in scope. A preventative measure implies a strategy to avoid something harmful before it happens, rather than addressing its effects after they occur. An alternative treatment usually involves a different form of therapy that may not be scientifically validated, which does not relate directly to the concept of neutralizing poison. Thus, recognizing the precise definition and function of an antidote is essential in understanding its role in medical treatment.
