Coins from Cyrene, in what is now Libya, carry the familiar emblem, representing silphium, a now-extinct plant used as a cooking spice, perfume, aphrodisiac, and… contraceptive.
An aphrodisiac is a substance that increases libido when consumed. Aphrodisiacs are distinct from substances that address fertility issues such as impotence 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.
