2

Primary toxic components are needle-shaped insoluble calcium oxalate crystals and soluble oxalate salts

Toxicity Snapshot

Toxic PartsAll parts of the plant are toxic
Exposure RouteIngestion is the primary exposure route; direct contact with plant sap can also cause skin or mucosal irritation
Toxic CompoundsInsoluble needle-shaped calcium oxalate crystals (raphides); Soluble oxalic acid and its salts; Dicarboxylic acids

First Aid & Prevention

First 30 Minutes

  • • Remove all remaining plant material from the mouth/skin, and rinse affected areas with cool clean water for 10-15 minutes
  • • Offer small sips of water or milk to dilute toxins if ingested; do not induce vomiting unless instructed by a medical professional or veterinarian
  • • Monitor for swelling, difficulty breathing, or severe pain, and record the approximate amount of plant ingested for medical providers

Contact Vet Immediately

  • • If the affected individual develops difficulty breathing, difficulty swallowing, or excessive mouth/throat swelling
  • • If vomiting, diarrhea, bleeding, or neurological symptoms (seizures, uncoordinated movement) appear
  • • If a large quantity of plant was ingested, or the affected party is a bird, young child, or small pet

Prevention

  • • Keep the plant out of reach of children, pets, and livestock, especially birds that face extreme toxicity risk
  • • Wear gloves when handling the plant to avoid sap contact with skin or mucous membranes
  • • Clearly label the plant as toxic if kept in shared household or public garden spaces

Treatment & Prognosis

  • • Perform decontamination of affected areas and provide targeted symptomatic care as clinically indicated
  • • Administer analgesics for pain, antihistamines if required, and glucocorticoids to reduce severe swelling
  • • Provide calcium supplementation for very large ingestions, and monitor liver and kidney function for signs of damage

Scientific NameSyngonium podophyllum
AliasesArrow-Head Vine、Green Gold Naphthysis、African Evergreen、Trileaf Wonder
Toxicity Grade
HumansModerate
CatsModerate
DogsModerate
HorsesModerate
Target Organs
Oral cavityGastrointestinal tractRespiratory tractLiverKidneysHeartUterus
Mechanism of Action

• Needle-shaped calcium oxalate raphides penetrate mucous membranes on contact, causing immediate pain, swelling, and local irritation

• Soluble oxalates bind to calcium in the body, leading to hypocalcemia, organ damage, and heart rhythm abnormalities in cases of high exposure

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Birds: Extremely severe (life-threatening) toxicity, even small ingestions can cause fatal effects
Confusion Risk

The following plants look similar and may be confused:

Philodendron Philodendron species
Both are vining Araceae family plants with similar broad, often arrow-shaped foliage; both are toxic, containing calcium oxalate crystals as their primary toxic component
