Let’s learn more about this.

Why Are Snake Plants Potentially Toxic to People?

A particular chemical called Saponin is behind the toxicity of snake plants. They produce this chemical as a natural fungicide and insecticide, which is beneficial for them; it has been proven toxic to living things. By living things, we mean humans and pets alike. The potential risk of toxicity happens when:

  • One eats the plant: We can’t tell why someone would want to eat a snake plant. Is it out of sheer curiosity or belief that it can cure a disease? But one thing we are certain of is that ingesting a snake plant is potentially toxic for you. Their bitter taste is yet another discomfort. However, we can’t rule out that children may just want to explore and eat the plant. Ingesting a snake plant is exactly where the danger lies.
  • One comes in contact with the plant’s juices or sap: Although snake plants are fairly safe to touch, the liquid from their leaves can be harmful. Their sap has been proven to potentially result in a skin condition called dermatitis that appears in the form of a skin rash or irritated skin.

It is important to note that every part of the snake plant is potentially toxic to humans, and this is because the Saponin toxins are present all over the plant.

From the stiff, upright, and beautiful leaves to the long stem, the scented flowers, and the occasional berries, literally all parts have Saponin. You, therefore, need to find ways to protect yourself, your pets, and your children from ingesting any part of the plant.

What Happens When People Consume Snake Plants?

We will forgive you if you have attempted to eat a snake plant! And we are glad you are reading this right now because you will understand what can happen when you or your child eats a snake plant.

Consuming a snake plant can result in mild to moderate poisoning.

We mentioned earlier that snake plants have a bitter taste, and this is because of the chemical called Saponin. So, the minute you try to put a snake plant in your mouth, you’ll experience a bitter, unpleasant taste followed by a burning sensation. This plant is simply unpalatable; people and animals try to avoid it.

In case you or your child decides to ignore the taste and continue sampling the plant, here are common symptoms you can expect to manifest:

  • Visible swelling will occur on your lips, tongue, whole mouth, and esophagus.
  • Feelings of nausea will arise, and this can also result in vomiting.
  • And because snake plants are not fit for human consumption, diarrhea is another symptom to expect.
  • When the plant hits the stomach, abdominal pains begin.
  • Loss of appetite is yet another symptom.

Another possible risk we can’t neglect to mention again is the potential risk when your skin comes in contact with the sap from the leaves of a snake plant. Unlike pets that have furry protective skin, humans have exposed skin. If you allow the juice of a snake plant to touch your skin, you may experience symptoms of dermatitis that could leave you with rashes and uncomfortable skin irritation.

Also, the tip of the leaves of a snake plant is pointed, which can potentially prick you when you touch it. Luckily, this is something you can easily avoid.
