Which term refers to substances used to treat disease or relieve symptoms?

• A. Vaccines
• B. Supplements
• C. Anesthetics
• D. Medications

Answer: (D)

Medications are substances used to treat disease or relieve symptoms. They cover a wide range of products, from prescribed drugs to over-the-counter items, and can come in pills, liquids, injections, or topical forms. The goal is to influence body functions to fight illness, ease symptoms, or support healing. Vaccines, for example, are used to prevent disease by building immunity rather than treating an active illness. Supplements provide nutrients and support health but aren’t primarily used to treat disease. Anesthetics numb or block sensation during medical procedures. Because the prompt asks for a term that covers substances used to treat disease or relieve symptoms, medications is the best fit.
