A substance that is used as medicine is called

• A. medicine
• B. poison
• C. drug
• D. herb

Answer: (C)

In pharmacology, a substance that affects the body's functions and is used to treat or prevent illness is called a drug. A drug is the broad term for any chemical that causes a change in the body, and when that substance is used for healing, it becomes a medicine or medication. The reason this fits best is that the prompt is asking for the label of the substance itself, not the specific use or a plant source. Medicines are examples of drugs, but the general term for the substance is drug. A poison is anything harmful, so it isn’t the right label for a substance used as medicine. A herb refers specifically to plant material, which is not necessary for a substance to be used as medicine.
