What Makes Alocasia Plants Toxic?

All parts of an Alocasia plant contain calcium oxalate crystals. These crystals are needle-shaped and very irritating and poisonous to both humans and animals if ingested. So, is Alocasia Poisonous to dogs, cats, and other pet animals? The answer is sadly yes!
As well as calcium oxalate, Alocasias also contain other toxic compounds including –
- Asparagine – causes nausea and vomiting
- Oxalic acid – causes swelling, burning pain, and injury
These compounds can cause a seriously painful reaction if the plant is eaten. Even the sap within the plant and the water you use to care for it can hold toxins. Therefore, you need to take care even when simply handling the plant.
6 Major Symptoms of Alocasia Poisoning

If a human or animal ingests part of an Alocasia plant, they are likely to experience the following symptoms:
- Burning pain in the mouth and throat
- Swelling of the mouth or throat
- Nausea and vomiting
- Diarrhea
- Dermatitis or skin irritation from contact with sap
- Injury to the eyes or mouth from oxalate crystals
Pets are most at risk of eye injuries from exposure to Alocasia as the oxalate crystals can become embedded in eye tissue causing significant damage and pain.
In rare cases, kidney failure is also possible in animals that ingest large amounts of the plant.
Is It Safe To Have An Alocasia At Home?
A very good question. If it’s a toxic plant, is it safe just to keep a room having an aesthetic appeal? See, Alocasias are toxic, but they can be safely kept in a home as long as some precautions are taken. Relaxed, haa?
Let’s see what are those precautions.
Keep Out of Reach of Children and Pets
This is the most important thing you can do. Place your Alocasia somewhere totally out of reach, such as on a high shelf or in a hanging basket. Make sure pets, especially curious cats, have no way of accessing the plant.
Wear Gloves When Handling
Always wear gloves when you need to handle your Alocasia. This prevents the sap from contacting your skin and causing irritation. Dispose of the gloves carefully after use.
Wash Hands After Touching
If you do happen to touch the plant with bare hands, immediately wash your hands well with soap and water. Be very careful not to touch your eyes or mouth before washing up.
Avoid Reusing Water
Don’t reuse the water you use for watering your Alocasia. The toxins can leach into the water so dispose of it down the drain after use.
Supervise Children Around The Plant
If you have an Alocasia in a common area, don’t allow young children near it unsupervised. Teach older children not to touch the plant and explain it can cause significant pain if eaten.
