Papaver somniferum
Papaver somniferum is the opium poppy, cultivated for edible seeds and for its latex, which contains morphine, codeine, and other alkaloids.
Opium: The dried latex of the opium poppy, containing morphine, codeine, and other alkaloids. Incisions in unripe capsules release the latex that defines the species’ drug-producing use.
Poppy seed: The small oil-rich seed of Papaver somniferum, used as food and pressed for oil. Seeds are a major food product of the species and are distinct from its latex.
Domestication: The inherited transformation of wild organisms through human management and selective breeding. Cultivated forms of this poppy reflect a long history of human selection and use.
Papaver rhoeas: The common poppy, a Eurasian flowering species with red petals and no comparable opium yield. It is a familiar poppy often confused with the opium poppy but lacks its latex-based use.
Opioid: A substance that activates opioid receptors, including natural, semisynthetic, and synthetic drugs. The plant’s best-known alkaloids belong to this wider pharmacological class.
Morphine: A potent opioid alkaloid that acts primarily at mu-opioid receptors and is used to relieve severe pain. It is the principal analgesic alkaloid obtained from opium poppy latex.
Poppy seed oil: A pale edible oil pressed from poppy seeds and also used in paints and other products. It is a value-added product from the crop’s seeds rather than its opium latex.
Neolithic: The prehistoric period marked in many regions by farming, settled communities, and domesticated plants and animals. Archaeological evidence places early opium poppy cultivation in Neolithic contexts.
Papaver orientale: An ornamental perennial poppy native to the Caucasus and adjacent regions, grown for large flowers. Its horticultural role contrasts with the opium poppy’s food and alkaloid production.
Opioid use disorder: A treatable medical condition involving problematic opioid use that causes significant impairment or distress. Dependence and harmful use can follow exposure to medicines derived from poppy alkaloids.
