Human Potential

• According to the University Of Arkansas' website, ingestion of the flowers, leaves, stems or seeds produces a wide range of symptoms from mild abdominal cramps to serious cardiac complications.
  
  

Animal Potential

• The American Society for the Prevention of Cruelty to Animals lists the vinca plant as toxic for animals. Cats, dogs and horses will suffer from symptoms such as vomiting, diarrhea, low blood pressure, tremors, seizures, depression, coma and possible death if vinca is eaten.
  
  

Considerations

• Those who ingest the vinca plant should seek immediate medical treatment, even if symptoms are not yet present. Take a sample of the plant to the doctor (or veterinarian) to aid with identifying the plant and the level of its toxicity.
