The combining form pharmac(o) means which substance?

Explanation:
pharmac(o) is a combining form that means drug. The o is just a linking vowel used to join the root to suffixes, giving terms like pharmacology or pharmacokinetics. The root comes from Greek pharmakon, which historically means drug (and sometimes poison), but in modern medical terms it indicates a drug or medication. So this combining form identifies a substance as a drug. Other bodily substances use different roots, such as hist- for tissue, oste- for bone, and neur- for nerve, which is why those would not fit.
