Those are not aphrodisiac. They are hallucinogenic. You can go high on throat spray at 500mg to hallucinations no need to go find a dealer. Opium was pretty accessible for this plot as well. However, aphrodisiac is considered specifically stimulating the sexual related hormones which creates physical arousal against will. But found some academic articles on their "non-existence". But all examples on Internet are stuff like nuts, fruits, drinks.. Yet no compound in them in common to stimulate. The reaction of arousal is specific to person.
