An aphrodisiac is a substance that increases libido when consumed. Aphrodisiacs are distinct from substances that address fertility issues or secondary sexual (dys)function such as erectile dysfunction (ED).
The name comes from the Greek ἀφροδισιακόν, aphrodisiakon, i.e. "sexual, aphrodisiac", from aphrodisios, i.e. "pertaining to Aphrodite", the Greek goddess of love. The opposite substance is an anaphrodisiac.
