Exposure RouteIngestion, direct contact with mucous membranes (mouth, eyes, nose)
Toxic CompoundsCalcium oxalate; Oxalic acid

First Aid & Prevention

First 30 Minutes

  • • Remove all remaining plant material from the exposed subject's mouth, skin, or affected area
  • • Rinse the affected area thoroughly with cool, clean water to reduce irritation
  • • Offer small sips of plain water or milk to dilute oxalates if the subject is alert and able to swallow

Contact Vet Immediately

  • • Severe difficulty breathing or swallowing develops after exposure
  • • Persistent vomiting, diarrhea, or pain lasts longer than 2 hours
  • • Exposure occurs in birds, as they face severe, life-threatening toxicity risk

Prevention

  • • Keep the plant out of reach of pet birds, other pets, and young children
  • • Never consume any part of the plant, including ripe or unripe fruits
  • • Wear disposable gloves when handling the plant to avoid potential skin irritation

Treatment & Prognosis

  • • Perform decontamination (induced vomiting, activated charcoal administration) under professional medical/veterinary supervision
  • • Administer mucosal protectants to soothe irritated gastrointestinal and respiratory linings
  • • Provide analgesics for pain relief and antihistamines as needed to reduce swelling
  • • Deliver supportive care to manage presenting symptoms as they arise

Professional Toxicology

Scientific NameCissus amazonica Linden
AliasesAmazonian vine、Vitis amazonica (Linden) G. Nicholson
Toxicity Grade
HumansLow
CatsLow
DogsLow
HorsesLow
Target Organs
MouthPharynxLarynxGastrointestinal tractRespiratory tract
Mechanism of Action

• Sharp calcium oxalate crystals and oxalic acid irritate and damage mucous membranes on contact

• Oxalate exposure triggers edema of the pharynx and larynx, leading to breathing and swallowing difficulties

• Gastrointestinal tract irritation causes salivation, vomiting, and diarrhea post-ingestion

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Birds: Severe, potentially fatal toxicity if any amount of the plant is ingested
Confusion Risk

The following plants look similar and may be confused:

Other Cissus species Cissus spp.
Visually highly similar to other Cissus varieties, most of which also carry low toxicity risk, making exact toxicity differentiation difficult without formal botanical ID
Other Vitaceae (grape family) species Vitaceae spp.
Related to common grape vines and other family members that often have similar low toxicity profiles, leading to frequent misidentification
