First Aid & Prevention
First 30 Minutes
- • Remove all remaining plant material from the mouth of the exposed person/animal

- • Collect a sample of the ingested plant for formal identification to guide treatment
- • Rinse the mouth with clean water to remove residual plant matter if the exposed subject is conscious
Contact Vet Immediately
- • Any confirmed or suspected ingestion of any part of this plant, especially berries
- • Appearance of any abnormal symptoms including salivation, vomiting, uncoordinated movement or tremors after exposure
- • Occurrence of seizures, bloody diarrhea or altered consciousness after potential plant exposure
Prevention
- • Keep this plant out of reach of children, pets and livestock, especially the fallen berries
- • Label the plant clearly to avoid accidental ingestion or confusion with visually similar non-toxic plants
- • Remove dropped berries immediately as they are highly toxic and attractive to children and pets
Treatment & Prognosis
- • Perform decontamination (emesis, activated charcoal administration) as soon as possible if clinically appropriate
- • Provide supportive care including intravenous Ringer-Lactat solution to maintain hydration and electrolyte balance
- • Control seizures with anticonvulsants such as diazepam and phenobarbital
- • Administer antibiotics such as amoxicillin if secondary infection is suspected
- • Monitor the exposed subject for at least 72 hours due to risk of prolonged seizures
