Dieffenbachia Toxicity: Real Risks vs. Internet Myths

Your friend's email claims dieffenbachia "kills kids in 1 minute, adults in 15." This is false alarmism. Here are the facts:

Actual Risks

Dieffenbachia sap contains calcium oxalate crystals. Effects of ingestion:

• Burning mouth/throat
• Swelling tongue/lips
• Hoarse voice, difficulty swallowing
• Nausea, vomiting, diarrhea
• Eye pain/corneal damage IF sap rubbed in eyes
• Rare: Airway swelling requiring emergency care

What DOESN'T Happen

• Death in minutes (no documented cases)
• Blindness from casual touch (need sap + eye rubbing)
• Toxicity from merely touching leaves

Real-World Context

• Common houseplant for decades with minimal incidents
• Tastes intensely bitter—kids/pets spit it out immediately
• Medical treatment: rinse mouth, cold fluids, monitor swelling
• ER visit warranted for child ingestion or significant swelling

Your Cordyline (Ti Plant) Issue

Separate problem: wilting, drying leaves = overwatering + insufficient light.

• South window, blinds open all day
• Water only when top half of soil dry
• Empty drain tray 1 hr after watering
• Terracotta pot helps (breathes)
• May take weeks to regrow roots

Bottom Line

Keep dieffenbachia away from unsupervised toddlers/pets. Don't panic. Your cordyline needs less water, more sun.
