History for toxic

Sometimes people put poison on the points of arrows. Even a slight wound from such an arrow can be fatal. The ancient Greeks referred to arrow poison as toxikon, short for toxikon pharmakon, literally, “bow drug” (from toxos, “bow”). As Latin toxicum, the word was applied more generally to any poison. The English word toxic comes from this Latin word.
