Nowadays, more and more people are interested in houseplants and keep many houseplants in their houses. Houseplants are famous for their air-cleaning abilities and good benefits besides providing a beautiful environment for our houses. However, little did we know that these useful plants can be toxic too.
Many people might be aware of the benefit of houseplants, but some of them might be dangerous and can be a hazard to children, an elderly person with dementia and even pets. The poisoning from these plants can occur from:
- Skin contact with sap or juices
- Eating or touching leaves
- Ingesting berries, blossoms, or roots
- Eating soil
- Drinking water from the plant tray
According to Dengarden, most garden centers don’t provide warning labels on their potted plants noting possible toxicity, so be sure NOT to keep these 10 plants where it can be reached by children or pets:
This plant contains calcium oxalate crystals which are toxic to both humans and animals, so keep it on high window sills or shelves.
Humans: Ingesting this has a mild side effect on human and children that includes a dermatitis reaction and the swelling of the mouth and digestive tract. In rare cases, there have been fatalities in children after ingesting large amounts of it.
Cats and Dogs: It has a much more serious effect on pets with reports of spasms, seizures, pain, and the swelling—and seems to be more toxic to cats.
Considered one of the best plants for removing impurities from the air, it is mildly harmful in small quantities but can also produce uncomfortable and serious side effects.
Humans: Might cause burning of the mouth, skin irritation, swelling of lips, tongue, and throat, vomiting, and diarrhea.
Cats and Dogs: Drooling, choking, swelling of mouth and tongue, difficulty breathing, and stomach upset. It can also lead to renal failure and death.
