Aphrodisiac

n. drug or food that arouses sexual desire

adj. stimulating, arousing sexual desire

An aphrodisiac is an agent which is used to increase sexual desire . The name comes from the Greek goddess of Sensuality Aphrodite. Throughout history, many foods, drinks, and behaviors have had a reputation for making sex more attainable and/or pleasurable. However, from a historical and scientific standpoint, the desired results may be because their users have chosen to believe they will be effective (the placebo effect). Medical science has not substantiated claims that any particular food increases sexual desire or performance. Some aphrodisiacs appear to gain their reputation from the principles of sympathetic magic, e.g. oysters, due to their shape. This also explains the trade in the phallic-looking horn of the rhinoceros, which is endangering this animal. Other animal-based aphrodisiacs gain their reputation from the apparent virility or aggressiveness of the animal source — such as tiger penis — also endangering the species.
