Toxicity on philodendron

philodendron with toxicity

What's Happening

All Philodendron species contain raphides—needle-like crystals of calcium oxalate. If ingested, these crystals cause immediate mechanical irritation, swelling, and burning of the mouth, tongue, and throat. Philodendrons are a leading cause of pediatric plant exposure calls to poison centers.

How to Fix It

  1. 1

    In case of ingestion: wipe the mouth with a damp cloth and offer small amounts of cool water or milk to help flush the crystals.

  2. 2

    Monitor for severe swelling or difficulty breathing; if symptoms escalate, contact a poison control center or seek medical attention immediately.

  3. 3

    For pets: watch for excessive drooling, pawing at the mouth, or vomiting. Contact a veterinarian if distress is noted.

How to Prevent It

Place all Philodendron varieties out of reach of small children and pets. Use hanging baskets or high shelves for vining varieties. Educate household members that the plant is for decoration only and never to be consumed.
