Toxicity Snapshot

Toxic PartsWhole plant, especially berries
Exposure RouteIngestion is the primary exposure route; direct contact with mucous membranes may cause local irritation
Toxic CompoundsPyrrol-3-carboxamide (pyrrol alkaloid)

First Aid & Prevention

First 30 Minutes

  • • If ingestion occurred within 2 hours and the affected individual/pet is conscious and not seizing, induce vomiting and administer activated charcoal
  • • Rinse the oral cavity thoroughly with clean water to remove remaining plant material and reduce irritation
  • • Closely monitor for early warning signs including tremor, excess salivation, anxiety, or uncoordinated movement

Contact Vet Immediately

  • • Any confirmed or suspected ingestion of any part of the plant, especially berries
  • • Onset of any symptoms including vomiting, diarrhea, tremor, ataxia, or seizures
  • • Recurrent or prolonged seizures lasting more than 5 minutes

Prevention

  • • Keep plants out of reach of children, pets, and livestock
  • • Avoid planting this species in yards or pastures accessible to free-roaming animals
  • • Educate household members to recognize the plant and avoid contact or ingestion

Treatment & Prognosis

  • • Gastrointestinal decontamination via emesis, activated charcoal administration, or gastric lavage as indicated
  • • Symptomatic care including intravenous Ringer's lactate fluid therapy, anticonvulsants (diazepam, phenobarbital) for seizure control, and broad-spectrum antibiotics if secondary infection is suspected
  • • Continuous monitoring of neurological status, temperature, and fluid balance for at least 72 hours post-ingestion

• Pyrrol-3-carboxamide alkaloid interferes with serotonin homeostasis, leading to neurological dysfunction and gastrointestinal irritation

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Dog: Confirmed toxicity with documented clinical cases; ingestion may cause treatment-resistant seizures lasting over 48 hours, with potential for fatal outcomes
Cat: No confirmed clinical cases reported, but high risk of severe adverse effects is expected due to feline sensitivity to Solanaceae alkaloids
Horse: No confirmed clinical cases reported, but ingestion is assumed to cause severe neurological and gastrointestinal damage requiring immediate veterinary intervention
Confusion Risk

The following plants look similar and may be confused:

Other Brunfelsia species Brunfelsia spp.
Visually nearly identical to Brunfelisa grandiflora, all Brunfelsia species share similar high toxicity profiles, making differentiation difficult for non-experts
Busy Lizzie Impatiens walleriana
Visually similar to Brunfelisa grandiflora, but Impatiens walleriana has a much lower toxicity risk compared to highly toxic Brunfelsia species
