Some house plants are more than just pretty to look at, they can be downright toxic. The Philodendron, for example, can cause skin irritation and burning if you touch its sap.

The Peace Lily is another plant that's often found in homes, but its flowers and leaves contain insoluble calcium oxalate crystals that can cause oral and gastrointestinal irritation if ingested.

If you're new to house plants, it's easy to get carried away with the beauty and charm of toxic plants like the Dieffenbachia. However, be aware that its sap can cause severe skin irritation, and ingesting any part of the plant can lead to oral and gastrointestinal irritation.

The good news is that there are plenty of non-toxic alternatives to choose from, so you can still have a lush and beautiful home without the risks.

The most toxic houseplants are often overlooked, but they can be deadly to pets and children. If ingested, they can cause a range of symptoms, from mild irritation to death.

English Ivy can cause skin irritation, burning throat, fever, diarrhea, hyperactivity, gasping breaths, weakness, tremors, staggering, and vomiting if ingested.

Oleander is a popular houseplant that's actually poisonous. Every part of it is toxic, and ingesting it can cause dizziness, vomiting, and even death, especially in pets and small children.

Sago Palm is a cute and small plant that's often placed on desks and bookshelves, but its leaves and seeds are toxic. While humans may only suffer some discomfort if they ingest it, the plant is extremely dangerous to dogs.

Areca Palm releases volatile organic compounds (VOCs) into the air, which can have unknown impacts on humans.

Houseplants That Are Safe

If you're looking to bring some greenery into your home without worrying about toxins, there are plenty of safe options to choose from. Some of the most popular houseplants that are safe for your family and pets include Spider Plants and Pothos.

One of the benefits of Spider Plants is that they're easy to care for and can thrive in a variety of lighting conditions. They're also great air purifiers, making them a popular choice for indoor spaces.

Pothos, on the other hand, is a low-maintenance plant that can survive with infrequent watering and low light. It's also a great air purifier, removing common indoor pollutants like formaldehyde and benzene from the air.

Areca Palm

The areca palm is a great choice for indoor spaces. It's known to remove air pollutants, making it a popular option for air-purifying houseplants.

One 2009 study found that the areca palm releases volatile organic compounds (VOCs) into the air, in addition to removing others. This is not unique to the plant itself, as microorganisms in the soil it grows in also contribute to VOC release.

Researchers have noted that the longevity of these compounds is unknown, so their impact on humans is still a topic of study.

The weeping fig is a beautiful plant, but it's not safe for your home if you have pets. The sap it emits is highly toxic and can cause itchiness in the eyes, wheezing, and coughing.

If you have parakeets or cats, you should definitely avoid the weeping fig altogether. They're particularly sensitive to its toxic sap.

Ingesting even a small amount of the plant can lead to irritation of the eyes and skin.

Peace Lily

The Peace Lily is a beautiful and low-maintenance addition to any home.

Some people might be surprised to learn that the Peace Lily is unlikely to be toxic if only small amounts of the leaves are handled or accidentally ingested.

However, eating large quantities of the leaves can be a different story, and it's essential to keep this in mind if you have pets or young children who might be tempted to nibble on the plant.

If you do happen to ingest a large amount of Peace Lily leaves, you might experience symptoms like burning mouth, excessive salivation, diarrhea, dehydration, lack of appetite, and vomiting.

These symptoms can be unpleasant, but in most cases, they can be treated with proper care and attention.

These plants are also pet-friendly, with no toxic compounds that can harm your furry friends if ingested.

Philodendron is a popular houseplant that thrives in low light conditions and requires minimal maintenance.

Its broad, heart-shaped leaves with wavy edges give it a tropical appearance that many homeowners love.

However, be aware that Philodendron contains calcium oxalate crystals in its sap, which can cause skin irritation and burning if touched.

Pothos

Pothos is one of the most popular houseplants in the world, and it's easy to see why - it's a low-maintenance creeper that can thrive in a variety of lighting conditions.

If pets chew on pothos leaves or vines, they may experience drooling, vomiting, and diarrhea, and may also exhibit some swelling in their mouth and/or tongue due to excessive drooling.

Keep in mind that if these symptoms are noticed quickly, the toxicity should have no long-term health effects.

Pothos is toxic to dogs and cats, and the symptoms of ingestion are similar to those of Philodendron, including choking, drooling, swelling of mouth and tongue, difficulty breathing, and stomach upset.

Cactus

Cactus is a beautiful and low-maintenance houseplant, but it's not suitable for homes with kids and pets. If ingested, it can cause throat and internal injuries due to the thorns.

Handle cactus with care, as the thorns can cause skin inflammation and vomiting due to the toxins. Wash your hands thoroughly or wear gloves when handling this plant.
