Toxic CompoundsCalcium oxalate crystals

First Aid & Prevention

First 30 Minutes

• Remove any remaining plant material from the affected individual's mouth immediately
• Rinse the mouth thoroughly with cool, clean water to reduce surface irritation
• Offer small sips of plain water or milk to neutralize remaining crystals if the individual can swallow safely

Contact Vet Immediately

• Persistent vomiting or retching lasting more than 30 minutes post-exposure
• Visible swelling of the mouth, tongue, or throat that impairs breathing
• Inability to swallow or excessive drooling that does not subside within 1 hour

Prevention

• Keep the plant placed out of reach of children, cats, dogs, and grazing livestock
• Wear disposable gloves when handling the plant to avoid skin irritation from sap
• Wash hands thoroughly with soap and water immediately after touching any part of the plant

Treatment & Prognosis

• Supportive care including fluid administration to address dehydration from vomiting
• Prescription anti-inflammatory medications to reduce swelling of oral and throat tissues
• Symptomatic pain management to reduce discomfort from tissue irritation

Target Organs

Oral cavityGastrointestinal tractUpper respiratory tract

Mechanism of Action

• Sharp, insoluble calcium oxalate crystals penetrate mucous membranes of the mouth, throat, and gastrointestinal tract on contact, triggering immediate pain, inflammation, and irritation

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Rabbit: Moderate toxicity risk; ingestion causes identical oral irritation, drooling, and gastrointestinal upset as seen in cats and dogs

Small rodent (guinea pig, hamster, gerbil): Low to moderate toxicity risk; ingestion may lead to mouth pain, reduced feed intake, and mild digestive distress

Pet bird: Low toxicity risk; occasional nibbling may cause mild oral irritation, while severe poisoning is extremely rare

Confusion Risk

The following plants look similar and may be confused:

Golden Pothos Epipremnum aureum

Shares a trailing growth habit and variegated leaf pattern; key difference: golden pothos has bright yellow-gold variegation, while variegated philodendron has pale white/light green variegation on softer, thinner heart-shaped leaves

Non-variegated Heartleaf Philodendron Philodendron hederaceum

Shares the same heart-shaped leaf structure and growth habit; key difference: it has solid deep green leaves with no pale variegation markings
