toxicity on Philodendron

Quick answer

If your Philodendron has toxicity, the most likely cause is: 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.

Start here:

  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.
