Corn poppy (Papaver rhoeas)

background
Corn poppy (Papaver rhoeas) is well known for its showy red flowers and should not be confused with the opium poppy (Papaver somniferum). In the Mediterranean, corn poppy greens are eaten as a vegetable.
Corn poppy extracts may reduce morphine withdrawal symptoms. However, there is insufficient available evidence in humans to support the use of corn poppy for any indication. Corn poppy may have iron-chelating activities and should be used cautiously in patients undergoing chelation therapy, or with thalassemia or anemia.
