Safety verdict
Toxic
Why
[confidence: high] [source: The Tortoise Table plant database, ASPCA Toxic Plant List (veterinary cross-reference), and exotic reptile vet review from a certified herpetological veterinarian] Dieffenbachia contains insoluble calcium oxalate raphides and proteolytic enzymes that cause intense oral irritation, swelling, and potential airway obstruction; ingestion by Hermann's tortoises can lead to drooling, difficulty swallowing, and systemic toxicity. This plant is consistently listed as toxic for tortoises and should be kept entirely out of their enclosure and grazing areas.
How much / how often
None — no amount is considered safe; complete avoidance is required.
Preparation
No preparation method neutralizes the calcium oxalate raphides or enzymatic toxins sufficiently to make this plant safe for consumption.
