What does it look like?
Hemlock is a herb that grows between one to two and a half metres high, with hollow stems that have reddish-brown or purple spots on the outside. The most notable feature of hemlock are the white flowers that grow in clusters.
This plant is poisonous to both humans and livestock, and is found across most of Australia, often occurring near stockyards, roadsides, and riverbanks.
Signs and symptoms
Hemlock is highly toxic and can cause serious health issues if ingested. Common symptoms of hemlock poisoning may include:
Burning in the digestive tract
Muscle weakness or muscle paralysis
Rapid heart rate followed by a decreased heart rate
Loss of speech
Unconsciousness or coma
In more severe cases, ingesting this plant can cause serious health issues.
Complications from hemlock poisoning include:
Central nervous system depression
Acute rhabdomyolysis, or breakdown of damaged skeletal muscle
Acute renal failure
What to do
Call triple zero (000) for an ambulance and/or fire services if the air is contaminated with smoke or gas.
Reassure the patient.
Call the Poisons Information Centre 13 11 26, and follow their advice.
If the patient is becoming drowsy, place them in the recovery position and continue to check their airway and breathing regularly.
Send any vomit, containers and notes with the patient to hospital.
