Apart from beautifying a home, house plants also contribute to purifying the air and may also be medicinal or edible. However, even a common household plant can be poisonous. For example, a common staple in the kitchen is the aloe vera, which has a soothing gel that helps with burns, but it can be toxic to cats and dogs.
It is advisable to keep such plants out of reach of children and pets. If you are worried, remove these plants from your house entirely.
Toxic plants cause poisoning in various ways, from ingestion to contact, to drinking the water from the tray. Nurseries seldom put warning signs on their potted plants, so it is vital you know which ones to avoid (or where to place them in your home). These 10 house plants are poisonous to humans or animals so be wary:
Philodendrons are popular house plants because they are easy to grow. However, they contain calcium oxalate crystals, which, when ingested, are toxic to animals causing seizures, spasms, pain, and swelling and mildly toxic to humans, causing a dermatitis reaction and swelling of the mouth and digestive tract.
The vining variety needs to be hung out of reach of kids and animals and trimmed regularly, while the non-vining plants should be placed on a shelf or window sill.
2. Peace Lilies
Though not a true lily, the dark leaves, white flowers, and low maintenance needs of peace lilies make them a common indoor plant. They are great as air purifiers. Peace lilies are not dangerous to touch, but if consumed, they are toxic to humans and animals. The entire lily family is toxic to cats.
Symptoms of poisoning in humans include difficulty speaking or swallowing, burning and swelling of lips, mouth, and tongue, diarrhea, vomiting, and nausea. Symptoms in cats include vomiting, lethargy, lack of appetite, renal and liver failure, and if left untreated, death. It is preferable to keep this plant if you have older children and no pets.
The brightly colored Caladium, or Elephant Ear, is a trendy decor in many homes. Its velvety leaves are tempting to touch or eat by toddlers and pets.
However, consumption of the leaves can cause eye pain, diarrhea, swelling, and vomiting. These are better off on higher shelves or outside.
4. Arrowhead Plant
The Arrowhead plant is often gifted to people because they are easy to care for. Young plants look bushy with heart-shaped leaves, while older plants have arrowhead-shaped leaves on climbing stems.

The delicate-looking oleander is so toxic that ingesting one leaf is known to cause death in some humans. Even its nectar produces symptoms.
