ZZ Plant Toxic?

All parts of the plant, especially the stem and standing water in its drip saucer, are toxic to humans, birds, and other animals.
It contains needle-shaped calcium oxalate raphides and soluble oxalates that cause immediate local irritation and systemic toxicity in high doses.
Ingestion can lead to serious effects including internal bleeding, heart rhythm abnormalities, and permanent liver or kidney damage.
FAQ
Is ZZ Plant toxic to Humans?
Salivation, vomiting, diarrhea, bleeding (gums, gastrointestinal tract, uterus), dyspnea (pharyngeal edema), difficulty swallowing (laryngeal edema); high doses cause convulsions, ataxia, hypotension, heart arrhythmia, liver and kidney damage (Severe)
Is ZZ Plant toxic to Cats?
Specific feline toxicity data is not formally documented, but expected symptoms include oral irritation, excessive drooling, vomiting, diarrhea, and potential systemic organ damage with large ingestions consistent with oxalate toxicity (Unknown)
Is ZZ Plant toxic to Dogs?
Specific canine toxicity data is not formally documented, but expected symptoms include oral irritation, excessive drooling, vomiting, diarrhea, and potential systemic organ damage with large ingestions consistent with oxalate toxicity (Unknown)
Is ZZ Plant toxic to Horses?
Specific equine toxicity data is not formally documented, but expected symptoms include oral irritation, drooling, colic, diarrhea, and potential systemic organ damage with large ingestions consistent with oxalate toxicity (Unknown)

Toxicity Snapshot
First Aid & Prevention
First 30 Minutes
- • Rinse mouth thoroughly with clean cool water immediately after ingestion to remove residual plant material
- • Wash affected skin with mild soap and water for 10-15 minutes if exposed to plant sap
- • Do not induce vomiting unless explicitly instructed by a medical professional or poison control
- • Collect remaining plant material for accurate identification to share with healthcare providers
Contact Vet Immediately
- • Any ingestion of ZZ plant material or contaminated saucer water by pets, children, or livestock
- • Development of symptoms including difficulty breathing, difficulty swallowing, abnormal bleeding, or seizures after exposure
- • Persistent pain, swelling, or gastrointestinal symptoms lasting more than 2 hours after exposure
Prevention
- • Keep ZZ plants out of reach of children, pets, and livestock, and empty drip saucers regularly to eliminate access to contaminated standing water
- • Wear protective gloves when handling ZZ plants to avoid sap contact, and wash hands thoroughly after handling
- • Never consume any part of the ZZ plant or use it for culinary or medicinal purposes
Treatment & Prognosis
- • Site-specific decontamination for ingestion or skin/mucous membrane contact
- • Symptomatic care including analgesics for pain, antihistamines for mild swelling, and glucocorticoids for severe swelling
- • Calcium supplementation for cases of very large ingestion to address oxalate-induced hypocalcemia
- • Monitoring and supportive care for respiratory function, heart rhythm, and liver/kidney function as needed
Professional Toxicology
• Needle-shaped calcium oxalate raphides penetrate mucous membranes on contact, causing immediate pain, swelling and tissue irritation
• Soluble oxalates bind to circulating calcium in the body, leading to hypocalcemia, crystal deposition in organs, and metabolic disruption in high doses
