Toxicity Snapshot

Toxic PartsAll parts of the plant, including standing water collected in the plant's pot saucer
Exposure RouteIngestion of plant material or toxic standing water, mucous membrane (mouth, eye) contact with plant sap, skin contact with broken plant tissue
Toxic CompoundsNeedle-shaped calcium oxalate crystals (raphides); Soluble oxalic acids and their salts; Arin glycoside; Triglochinin (cyanogenic glycoside); Saponins

First Aid & Prevention

First 30 Minutes

  • • Rinse mouth thoroughly with cool water immediately if any plant material is ingested
  • • Wash affected skin with soap and water for 10-15 minutes if exposed to plant sap
  • • Flush eyes with lukewarm clean water for at least 15 minutes if plant material enters eyes
  • • Do not induce vomiting unless explicitly directed by a medical or veterinary professional

Contact Vet Immediately

  • • Any ingestion of the plant by birds, cats, dogs, horses, or small children
  • • Presence of difficulty breathing, bleeding from the mouth/stool, or persistent vomiting/diarrhea
  • • Visible swelling of the lips, mouth, or throat that impairs swallowing or breathing

Prevention

  • • Keep the plant placed well out of reach of children, pets, and pet birds
  • • Wear disposable gloves when pruning or handling the plant to avoid contact with irritant sap
  • • Regularly empty water from the plant's pot saucer to prevent accidental ingestion of toxic standing water

Treatment & Prognosis

  • • Perform appropriate decontamination based on the route of exposure
  • • Administer analgesics to manage pain from mucosal irritation
  • • Prescribe antihistamines for mild swelling, and glucocorticoids for severe mucosal or throat swelling
  • • Provide calcium supplementation for cases of very large ingestion to address oxalate-induced hypocalcemia
  • • Deliver symptomatic supportive care as needed for presenting clinical signs

Professional Toxicology

Scientific NameAlocasia sanderiana W.Bull
AliasesKris plant、Sanders Pfeilblatt、Alokasie
Toxicity Grade
HumansModerate
CatsModerate
DogsModerate
HorsesModerate
Target Organs
Oral and throat mucosaGastrointestinal tractGingiva (gums)Respiratory tractUterusKidneys
Mechanism of Action

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

• Soluble oxalates bind to systemic calcium, potentially leading to low blood calcium levels and organ damage in cases of large ingestion

• Cyanogenic glycosides, arin, and saponins contribute to gastrointestinal irritation, bleeding, and systemic toxic effects

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Birds: Extremely high risk of severe, potentially fatal poisoning even from ingestion of very small amounts of the plant
Confusion Risk

The following plants look similar and may be confused:

Other Alocasia species Alocasia spp.
Most Alocasia species share very similar foliage morphology and growth habits, and nearly all carry comparable toxic compounds; no simple visual feature distinguishes Alocasia sanderiana from other genus members without taxonomic expertise
