First Aid Training - Poisonous plants and fungi


Many young children eat plant leaves or brightly coloured berries, but serious poisoning as a result rarely occurs.

However, ingesting even small amounts of foxglove or wild arum can cause nausea, vomiting, and stomach cramps; and large amounts are potentially fatal. Seizures may occur after ingesting laburnum seeds.

Serious poisoning as a result of eating mushrooms is also rare. Mushrooms found in the garden may cause nausea, vomiting, and occasionally, hallucinations. Death cap mushrooms cause vomiting and severe watery diarrhoea between 6 and 12 hours after ingestion and can be fatal.

Recognition features

There may be:

  • Nausea and vomiting.
  • Cramping abdominal pains.
  • Diarrhoea.
  • Seizures.

Your Aims:

If the casualty is conscious:

  • Ask them what they have eaten and reasure them.

  • Open the airway and check breathing
  • Be prepared to give chest compressions and rescue breaths if necessary.
  • Place them into the recovary position if the casualty is unconscious but breathing normally.
  • Dial 999 for an ambulance.
