noun

der Wirkstoff, -e

active ingredient

Ein Stoff in einem Mittel oder Medikament, der im Körper etwas Bestimmtes bewirkt.

The German word "Wirkstoff" is a compound noun made of:

  • Wirk (from wirken): "to act" or "to have an effect"
  • Stoff: "substance" or "material"

Meaning:
"Wirkstoff" means active ingredient or active substance, typically referring to the component in a medicine or chemical that produces the intended effect.

Similar words:

  • Bestandteil (component, ingredient)
  • Zutat (ingredient)
  • Medikament (medication, drug)

Difference:
While Bestandteil and Zutat refer broadly to any component or ingredient, Wirkstoff specifically highlights the part responsible for a biological or chemical effect. Medikament denotes the entire medicine or drug, not just the active substance.
