Monstera plants, often admired for their lush and striking foliage, have become an increasingly popular choice for indoor gardens. However, alongside their aesthetic appeal comes a pressing question: How toxic is Monstera to humans? Understanding the risks associated with these plants, especially if you have children or pets, is crucial for ensuring a safe home environment. In this comprehensive guide, we will explore the various aspects of Monstera toxicity, symptoms, treatment, and safety precautions you should consider. Let’s dive in.
How Toxic is Monstera to Humans?
Monstera plants contain calcium oxalate crystals, which are toxic to humans if ingested.
While Monstera plants are not fatally toxic, they can cause discomfort and irritation. These needle-like crystals are found in the leaves and sometimes in the stems, and when chewed or swallowed, they can irritate the mouth, throat, and digestive tract.

Symptoms of Monstera Toxicity in Humans
When a person comes into contact with the toxic parts of a Monstera plant, several symptoms may arise, including:
- Mouth and throat irritation
- Burning sensation
- Swelling of the lips, tongue, or throat
- Difficulty swallowing
- Nausea or vomiting
- In rare cases, difficulty breathing
These symptoms are generally mild and temporary but can be more concerning for children and pets.
What if a Baby Puts Monstera in Their Mouth?
If a baby puts a Monstera leaf in their mouth, it can lead to pronounced irritation. Due to their small size and developing systems, babies may experience more severe reactions.
Parents or guardians should immediately remove any plant material from the child’s mouth and rinse it with water. Monitoring for signs of swelling or other symptoms is essential, and seeking medical advice is advisable if symptoms persist.
Treatment for Monstera Toxicity in Humans
Treating Monstera toxicity involves symptomatic relief and ensuring the affected individual remains comfortable.
Here are steps you can take:
- Rinse the mouth with water to wash away any plant residue.
- Encourage the consumption of milk or yogurt, as these can help soothe irritation.
- Over-the-counter antihistamines can reduce swelling and discomfort.
- Seek medical attention if symptoms are severe or if breathing difficulties arise.
While Monstera toxicity is rarely serious, quick actions can mitigate discomfort and prevent complications.
Is Monstera Safe to Have in Your Bedroom?
For most adults, having a Monstera plant in the bedroom is generally safe, provided it is kept out of reach of children and pets.
Although the plant is not known for releasing harmful substances into the air, the risk is more about ingestion and contact. Consider placement carefully if you have curious toddlers or pets roaming your space.
Is Monstera Toxic to the Touch?
Touching a Monstera plant is generally safe, but care should be taken if you have sensitive skin.
The plant’s sap contains the same irritating crystals and may cause mild skin irritation for some individuals.
Wearing gloves when handling your Monstera can prevent potential irritation. Washing hands thoroughly after contact can also reduce the risk.
Is Monstera Poisonous to Babies?
Monstera plants can indeed pose a risk to babies, especially if ingested.
Due to their smaller size and underdeveloped immune systems, babies may experience more significant symptoms if they chew on or ingest plant parts.
As with any household item that could pose a risk, it’s best to keep Monstera plants out of reach of babies and young children to avoid accidental ingestion or contact.
Is Monstera Toxic to Dogs?
Monstera plants are toxic to dogs and can cause similar symptoms as observed in humans when ingested.
Dogs may experience drooling, oral irritation, vomiting, and difficulty swallowing. While these symptoms are distressing, they are typically not life-threatening.
To keep your pets safe, place Monstera plants in areas that are inaccessible to dogs, or consider hanging baskets or high shelves.

Understanding Monstera Plant Toxic Goo
The “toxic goo” often referred to by concerned plant owners is the sap exuded by Monstera plants, which contains calcium oxalate crystals. This sap can leak from damaged leaves or stems.
If you notice this sap while pruning or handling the plant, it’s advisable to avoid direct skin contact. Clean any residue on the plant with a damp cloth to reduce potential risks.
Conclusion
While Monstera plants bring beauty and a touch of the tropics to indoor spaces, understanding their toxic nature is crucial for maintaining a safe environment for all household members, including pets and children. By taking appropriate precautions, such as placing the plant out of reach, promptly treating any exposure, and understanding the symptoms of toxicity, you can enjoy the charm of Monstera without compromising on safety. For further peace of mind, consulting with a healthcare provider or veterinarian is recommended if exposure occurs.
