Pharmakeus

The ancient Greek term "pharmakos" later became the term "pharmakeus" which refers to "a drug, spell-giving potion, druggist, poisoner, by extension a magician or a sorcerer." A variation of this term is "pharmakon" (φάρμακον) a complex term meaning sacrament, remedy, poison, talisman, cosmetic, perfume or intoxicant. From this, the modern term pharmacology emerged.
