Love-powders or Potions
were drugs to excite lust. Once these lovecharms were generally believed in; thus, Brabantio accuses Othello of having bewitched Desdemona with drugs to waken motion; and Lady Grey was accused of having bewitched Edward IV. by strange potions and amorous charms. (Fabian, p. 495.)
