Chinese Evergreen Toxic?

Updated 2026-03-06| 2 min read| 1,994 found this helpful

1

Contains needle-shaped calcium oxalate raphides and soluble oxalate salts that drive all toxic effects.

2

Extremely severe toxicity confirmed for birds, while moderate toxicity applies to humans and most other species.

3

High exposure doses can lead to permanent liver/kidney damage, heart arrhythmia, and life-threatening neurological symptoms.

FAQ

Is Chinese Evergreen toxic to Humans?

Excessive salivation, vomiting, diarrhea, gum/gastrointestinal/uterine bleeding, throat swelling causing difficulty breathing/swallowing; high doses may cause seizures, poor coordination, low blood pressure, heart arrhythmia, liver and kidney damage. (Moderate)

Is Chinese Evergreen toxic to Cats?

Species-specific data not formally documented; expected to present with oral irritation, salivation, vomiting, and diarrhea consistent with calcium oxalate plant toxicity, with systemic effects at high doses. (Low)

Is Chinese Evergreen toxic to Dogs?

Species-specific data not formally documented; expected to present with oral irritation, salivation, vomiting, and diarrhea consistent with calcium oxalate plant toxicity, with systemic effects at high doses. (Low)

Is Chinese Evergreen toxic to Horses?

Species-specific data not formally documented; expected to present with oral irritation, salivation, vomiting, and diarrhea consistent with calcium oxalate plant toxicity, with systemic effects at high doses. (Low)

Toxicity Snapshot

Toxic PartsLeaves are the confirmed toxic part; all plant tissues are assumed to contain toxic calcium oxalate crystals per standard Araceae species traits.

Exposure RouteIngestion is the primary high-risk exposure route; direct contact with broken plant tissue may also cause mild to moderate skin or mucous membrane irritation.

Toxic CompoundsDicarboxylic acids; Needle-shaped calcium oxalate crystals (raphides); Soluble oxalic acids and oxalate salts

First Aid & Prevention

First 30 Minutes

• Rinse mouth/affected skin thoroughly with clean cool water to remove residual plant material and reduce oxalate exposure.
• Do not induce vomiting unless explicitly instructed by a medical provider or veterinarian.
• Document the approximate amount of plant ingested and monitor for early signs of swelling or breathing difficulty.

Contact Vet Immediately

• Presence of visible bleeding from gums, stool, or other body sites post-exposure.
• Signs of upper airway swelling including difficulty breathing, swallowing, or persistent hoarseness.
• Onset of seizures, disorientation, uncoordinated movement, or abnormal heart rhythm.

Prevention

• Keep the plant out of reach of children, pets, and pet birds (which face extreme fatal risk from small exposures).
• Wear disposable gloves when pruning or handling cut plant tissue to avoid skin irritation from sharp oxalate crystals.
• Clearly label the plant as toxic if kept in shared living, work, or educational spaces.

Treatment & Prognosis

• Perform appropriate decontamination followed by targeted symptomatic care based on symptom severity.
• Administer analgesics for pain relief, antihistamines for mild irritation, and glucocorticoids to reduce severe airway swelling.
• Provide intravenous calcium supplementation for cases of very high exposure to reverse systemic hypocalcemia from oxalate calcium binding.
