Known for its glossy, heart-shaped leaves and vibrant spathes, the Anthurium plant, also called the Flamingo Flower, is a popular choice among indoor plant enthusiasts. However, while it adds aesthetic appeal to homes, it is crucial to be aware of its potential hazards. This article aims to provide an informative, beginner-friendly guide on Anthurium’s toxicity, focusing on its impacts on humans, dogs, and cats.
How Toxic is the Anthurium Plant?
Anthurium plants are moderately toxic. They contain calcium oxalate crystals, which are harmful when ingested or when they come into contact with skin. This toxicity applies not only to pets but also to humans, making it essential to handle the plant with care.

Which Part of Anthurium is Poisonous?
Every part of the Anthurium plant is poisonous. The plant’s leaves, stems, flowers, and roots all contain calcium oxalate crystals. These microscopic, needle-like crystals can cause irritation and swelling when they come into contact with skin or are ingested.
Anthurium Toxicity to Dogs: Symptoms and Treatment
When ingested by dogs, Anthurium can cause several distressing symptoms due to its calcium oxalate crystals.
| Symptoms | Description |
|---|---|
| Oral irritation | Pain and swelling in the mouth, tongue, and lips. |
| Drooling | Excessive salivation due to irritation. |
| Difficulty swallowing | Caused by swelling and irritation. |
| Vomiting | An attempt to expel the ingested plant material. |
If you suspect your dog has ingested Anthurium, rinse its mouth with water and contact your veterinarian immediately. Do not induce vomiting unless directed by a veterinarian.
What to Do if Your Dog Eats Anthurium?
If your dog eats Anthurium, immediately wash out its mouth using a damp cloth or water. Contact your veterinarian without delay for advice. Your vet might suggest administering an antihistamine to reduce swelling and discomfort, followed by monitoring for any escalation of symptoms.
Anthurium Toxic to Cats
Anthurium poses a similar threat to cats as it does to dogs. Symptoms include oral irritation, drooling, vomiting, and difficulty in swallowing. Cat owners should be vigilant and consult a veterinarian if their feline is exposed to the plant.
Anthurium Poisonous to Humans and Touch
Anthurium is poisonous to humans if ingested and can also cause skin irritation. Its calcium oxalate crystals can lead to burning sensation, irritation, and swelling upon contact. Consuming parts of the plant can result in severe irritation in the mouth and throat.

Which Common Flowers are Highly Toxic to Dogs?
Besides Anthurium, several other common household plants are toxic to dogs:
| Plant | Potential Effects |
|---|---|
| Lilies | Kidney failure, especially in felines but dangerous for dogs too. |
| Azaleas | Vomiting, diarrhea, and in severe cases, death. |
| Sago Palm | Liver damage, vomiting, and potentially fatal. |
| Oleander | Heart arrhythmias, vomiting, and death. |
It is crucial for pet owners to recognize these and other hazardous plants, ensuring they are placed out of reach of curious animals or avoided altogether.
Conclusion
The Anthurium plant, while aesthetically pleasing, presents a toxicity risk to pets and humans due to its calcium oxalate content. By taking preventative measures such as keeping the plant out of reach, using protective gear when handling, and monitoring for symptoms in pets, potential poisoning incidents can be minimized. A well-informed approach ensures both safety and enjoyment of this beautiful plant.
Remember to consult appropriate professionals, such as veterinarians or medical practitioners, if you suspect exposure or ingestion of Anthurium or similarly toxic plants. Prevention and informed action are key to maintaining a safe environment for all family members, including our beloved pets.
