Opium

From SgWiki

Opium, or opïum is a narcotic analgesic drug which is obtained from the unripe seed pods of the opium poppy (Papaver somniferum L. or the synonym paeoniflorum).

[edit] Harvesting opium

To harvest opium, the skin of the ripening pods is scored by a sharp blade. The slashes exude a white, milky latex, which dries to a sticky brown resin that is scraped off the pods as raw opium.
