Health topics

Where Poppy appears in symptom search, and why. Being listed doesn't mean it's a proven treatment.

  • Cough

    Used in folk medicine for coughs. Not tested in trials, and eating the plant has caused poisoning.

  • Sleep Problems (Insomnia)

    Used in folk medicine for sleep problems. Not tested in trials, and eating the plant has caused poisoning.

Safety

Toxicity testing

  • Eating corn poppy can cause poisoning that resembles a morphine overdose. A hospital in Turkey reported five adults who had eaten it for its taste, not as medicine. Within 1 to 3 hours they had:

    • Nausea and vomiting
    • Restlessness, confusion and loss of consciousness
    • Seizures
    • Numbness and weakness in the arms and legs
    • Breathing difficulty and a slow heartbeat

    All recovered after a few days in hospital.[1]

What does the research say?

Traditional use

These are traditional uses, not proven treatments.

  • Corn poppy is used as a medicinal plant in Turkey, Iran and other countries:

    • For diarrhea, coughs and sleep problems
    • To ease pain and calm
    • To reduce opioid withdrawal symptoms
    • For bowel and bladder irritation, bronchitis, pneumonia and fevers with a rash
    [1]

  • In some regions corn poppy is added to salads. Its main natural chemicals are alkaloids called rhoeadine and rhoeagenine.[2]

Laboratory & animal research

Lab and animal results show what might be worth studying in people. They don't show that the herb has these effects in humans.

  • In rats, corn poppy extract had a calming effect, reduced movement, and eased withdrawal symptoms in rats dependent on morphine.[1]

Research in people

  • In one trial, men took a syrup of corn poppy combined with other herbs, and reported better sexual experience, with no serious side effects. Because the syrup contained several herbs, the effect can't be put down to corn poppy alone.[2]

In short

Eating corn poppy has caused poisoning with seizures, confusion and breathing problems.
