Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesise hundreds of chemical compounds for functions including defence against insects, fungi, diseases, and herbivorous mammals. Numerous phytochemicals with potential or established biological activity have been identified. However, since a single plant contains widely diverse phytochemicals, the effects of using a whole plant as medicine are uncertain. Further, the phytochemical content and pharmacological actions, if any, of many plants having medicinal potential remain unassessed by rigorous scientific research to define efficacy and safety.

An anaphrodisiac is a substance 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 privative prefix ἀν-, denoting negation, and aphrodisiac, from the Greek goddess of love, Aphrodite. Some people use anaphrodisiacs in order to curb a very high libido or due to hypersexuality. However anaphrodisiacs are also used by those with an average libido, at times due to having incessant schedules.

Nitrosoprodenafil is a synthetic designer drug found in "herbal" aphrodisiac products, which is a novel nitrosated analogue of sildenafil (Viagra). It has an innovative structure which acts as a prodrug, breaking down in the body to release both the PDE5 inhibitor aildenafil as well as free nitric oxide, which have powerfully synergistic effects. This dual mechanism of action has never been exploited by conventional pharmaceutical companies because of the risks involved; usually combining PDE5 inhibitors with nitric oxide releasers like amyl nitrite is contraindicated as it can cause a precipitous drop in blood pressure that can potentially result in death. Nitrosamines are also generally avoided in drug development as they can often be hepatotoxic, so while the combined mechanisms of action are likely to be effective, this drug also has severe risks of toxicity.
