Is Monstera Poisonous?

Monstera is mildly toxic to humans and is toxic to cats and dogs but is not considered lethal. 

All parts of the plant are harmful to ingest except the fully ripe fruit, which rarely develops on indoor Monstera. The toxicity comes from insoluble oxalate crystals in the juices inside the plant. Symptoms of Monstera poisoning include oral irritation, pain and swelling of mouth, tongue or lips, drooling, vomiting, and difficulty swallowing. Contact your doctor or veterinarian if you, your children, or pets are experiencing these symptoms.
