Opium 鸦片

Opium (poppy tears, with the scientific name: Lachryma papaveris) is the dried latex obtained from the (opium poppy, with the scientific name: Papaver somniferum). Opium latex contains approximately 12 percent of the analgesic alkaloid morphine, which is processed chemically to produce heroin and other synthetic opioids for medicinal use and for the illegal drug trade. The latex also contains the closely related opiates codeine and thebaine, and non-analgesic alkaloids such as papaverine and noscapine. The traditional, labor-intensive method of obtaining the latex is to scratch ("score") the immature seed pods (fruits) by hand; the latex leaks out and dries to a sticky yellowish residue that is later scraped off and dehydrated. The word "meconium" (derived from the Greek for "opium-like", but now used to refer to infant stools) historically referred to related, weaker preparations made from other parts of the opium poppy or different species of poppies.
