An aphrodisiac is a substance alleged to increase libido, sexual desire, sexual attraction, sexual pleasure, or sexual behavior.[1][2][3] These substances range from a variety of plants, spices, and foods to synthetic chemicals.[1][4] Natural aphrodisiacs, such as cannabis or cocaine, are classified into plant-based and non-plant-based substances.[4][5] Synthetic aphrodisiacs include MDMA and methamphetamine. Aphrodisiacs can be classified by their type of effects (psychological or physiological).[1] Aphrodisiacs that contain hallucinogenic properties, such as bufotenin, have psychological effects that can increase sexual desire and sexual pleasure.[1][3] Aphrodisiacs that have smooth muscle relaxing properties, such as yohimbine, have physiological effects that can affect hormone concentrations and increase blood flow.[1][4]
Aphrodisiac effects may be due to the placebo effect.[2] Substances that inhibit effects that aphrodisiacs aim to enhance are called anaphrodisiacs,[2] which have the opposite effects on libido.
Both males and females can potentially benefit from the use of aphrodisiacs, but they are more focused on males, as their properties tend to increase testosterone concentrations rather than estrogen concentrations.[3] This is in part due to the historical context of aphrodisiacs, which focused solely on males. Only recently has attention been paid to understanding how aphrodisiacs can aid female sexual function.[5] In addition, cultural influences on appropriate sexual behavior of males and females also play a part in the research gap.[5]
