Safety Overview
1.Opium Poppy — At a Glance
The Opium Poppy, botanically known as Papaver somniferum, is an annual herbaceous plant belonging to the Papaveraceae family. It typically grows to a height of 30 to 150 cm, presenting a robust, glaucous-green stem that can be sparsely branched. Its leaves are broad, lobed, and clasp the stem, with sizes ranging from 5 to 30 cm long and 2 to 15 cm wide. They exhibit a characteristic grey-green coloration and a slightly waxy, sometimes subtly pubescent, surface.
The striking flowers of Papaver somniferum are solitary and terminal, boasting delicate petals that can span up to 15 cm in diameter. Their colors vary widely, encompassing shades of white, pink, red, and purple, often adorned with a distinct dark blotch at the base of each petal. The fruit is a distinctive, globose to ovoid capsule, which can reach 2 to 10 cm in length and contains numerous tiny, kidney-shaped seeds. When incised, the unripe capsule exudes a milky white latex, the raw material for opium.
Native to the Mediterranean basin, including parts of Southern Europe and Western Asia, Papaver somniferum has been extensively cultivated across various temperate and subtropical regions globally for millennia, primarily for its significant pharmaceutical compounds and, historically, for its edible seeds and oil. Its adaptability to well-drained soils and full sun has facilitated its widespread distribution.
