Anaphrodisiac

adj. able to suppress sexual desire

n. substance that suppresses sexual drive

An anaphrodisiac is something that quells or blunts the libido. It is the opposite of an aphrodisiac, something that enhances sexual appetite. The word anaphrodisiac comes from the Greek prefix αν-, denoting negation, and the Greek goddess of love, Aphrodite.Side effects of certain medications may be anaphroditic in nature (e.g. SSRIs and certain antipsychotics), however, there are no substances that have safe anaphroditic effects without major side effects.Herbal anaphrodisiacs have been employed by various religious sects and orders throughout history. Most commonly, Chaste Tree (Vitex agnus-castus) has been used to normalize hormones in both men and women. An over-active libido is very often treated herbally by addressing poor adrenal function.
