The Correct Option is B
Solution and Explanation
Concept:
Each aromatic drug has a main chemical (active principle) responsible for its effect. Clove is famous in dentistry for relieving toothache, so you need to know which compound gives that pain-relieving action.
Step 1:
The chief constituent of clove oil is eugenol, making up the large majority of the oil. Eugenol has a numbing, analgesic and antiseptic action, which is why clove oil is dabbed on aching teeth.
Step 2:
The distractors belong to other drugs: menthol comes from peppermint (cooling effect), gingerol from ginger (pungent taste), and thymol from thyme (antiseptic). None of these is the clove principle.
Step 3:
So the analgesic active principle of clove is eugenol.
Answer: Option (2) — Eugenol.
