Kalanches are poisonous plants. They belong to a group of plants that contain naturally-occurring poisons that affect the heart. The toxins in kalanchoe plants are similar to digitalis or digoxin a common heart medication used in both human and veterinary medicine. The severity of the poisoning depends upon the amount of plant eaten. All parts of the plant are considered toxic, even the water in the vase of cut kalanchoe flowers is dangerous.
Aglaonema or Chinese Evergreen plants are poisonous with a #2 toxicity level because of the calcium oxalate crystals in the plant.
