Mrs. Loudon,
Botany for Ladies
“ The opium of commerce is produced in hot countries; but even in England, any one who chooses may procure a small quantity of opium, by wounding the fleshy capsule of the common White Poppy when it is about half ripe. A milky juice will issue from the wound, which when dry becomes opium, and would be poisonous if taken in excess. The capsule of the White or Opium Poppy has, when ripe, a little window-like opening under each stigma for the discharge of the seeds, which contain abundance of oil, and may be safely eaten, though the rest of the plant is poisonous. ”
