Toxic PartsAll plant parts
Exposure RouteIngestion is the primary exposure route; contact with broken plant sap may cause mild skin irritation in sensitive individuals
Toxic CompoundsCalcium oxalate; Oxalic acid

First Aid & Prevention

First 30 Minutes

  • • Remove all remaining plant material from the mouth of the exposed individual/pet immediately
  • • Rinse the mouth and throat thoroughly with cool, clean water to reduce mucosal irritation
  • • Do not induce vomiting unless explicitly instructed by a medical professional or veterinarian

Contact Vet Immediately

  • • Exposure occurs in birds, as this species faces severe, potentially fatal toxicity
  • • Severe symptoms develop including difficulty breathing, inability to swallow, or persistent vomiting/diarrhea
  • • Exposure occurs in very young, elderly, or immunocompromised individuals/pets

Prevention

  • • Keep the plant out of reach of pet birds, young children, and curious household pets
  • • Wear gloves when pruning or handling the plant to avoid contact with oxalate-containing sap
  • • Clearly label the plant if kept in homes or aviary spaces to prevent accidental ingestion

Treatment & Prognosis

  • • Perform appropriate decontamination including oral rinsing and activated charcoal administration if ingestion was recent
  • • Administer mucosal protective agents to soothe irritated throat and gastrointestinal tract tissues
  • • Provide analgesics for pain relief and antihistamines for severe swelling per professional medical guidance

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Birds: Severe (+++) toxicity; ingestion may cause serious adverse effects or death
Confusion Risk

The following plants look similar and may be confused:

Other Cissus species Cissus spp.
Other Cissus species are visually similar to Kangaroo vine and also carry low toxicity levels, requiring careful morphological identification to avoid misclassification
Other grape family species Vitaceae spp.
Many Vitaceae species share similar leaf shape and vining growth habit with Kangaroo vine, most carrying low to moderate toxicity levels
