Wat is aphrodesiac?

Desire Enhancement: An aphrodisiac is a drug, food, etc., that excites sexual desire (libido). There is controversy as to the aphrodisiac properties of different substances. Libido is clearly linked to levels of sex hormones, especially testosterone. Testosterone replacement can increase libido. Erectile dysfunction drugs such as viagra (sildenafil) are not considered aphrodisiacs as they enhance performance and not libido.
