There are many houseplants that can be allergic or toxic for animals and humans, in varying degrees of severity. Monstera is, thankfully, generally not fatal. Actually, it’s classified as a low-level toxic plant in this regard.

However, it can trigger extremely unpleasant reactions. Let’s discuss the reasons, effects, and what you should do if you’re experiencing the symptoms of an allergy to monstera.

Monstera is sometimes referred to by its other names, such as Swiss cheese plant or hurricane plant, and belongs to the Araceae family.

Monstera can be mistaken with split-leaf Philodendrons however, technically speaking, philodendron and monstera are not the same plant.

Why Is Monstera Toxic to Humans?

There’s a specific reason for toxicities in monstera. Although some plants can trigger allergic reactions due to their pollen (a frequent phenomenon) Monstera is an even more painful sting in the sense of.

It is due to the existence of calcium Oxalate crystals. There are some scientists who believe there are minor toxicants in certain monstera, however, these have yet to be verified as the primary reason for allergic reactions.

The crystals add an irritant to the sap of the plant. When sap comes into contact with skin, it can cause irritation, itchiness and swelling. It can also cause the condition is called eczema. (Nasty.)

Naturally, these signs are particularly unpleasant If, for any reason, the same sap or crystals come into contact with your lips, eyes tongue, and other areas that are sensitive to the body.

If you or an infant manages to chew on a huge leaf, or swallow anything and then ingest it, it can trigger an extremely uncomfortable and unpleasant (possibly uncomfortable) inner reaction.

In rare instances in the event of prolonged exposure (or an excessive amount is consumed) it could be dangerous. This is why these calcium oxalate crystals should not be played with.

What Are Calcium Oxalate Crystals?

Oxalate crystals aren’t common – you’ll probably drift by them throughout your daily day. They can be found in a variety of green leaves and vegetables.

When the oxalate is combined with calcium, and is found in a space with inadequate water, it forms crystals that turn to form hard dry deposits. When this happens, we develop the well-known kidney stones.

It’s the exact substance. In certain plants, such as monstera and dieffenbachia, the crystals may form into the shape of a needle, that is sharp and can cause micro-lacerations.

As a bonus, dieffenbachia’s crystals are so strong, they could even result in a loss of ability to speak when ingested.

The barbs and demands of the crystals can irritate the throat and mouth membranes to the point it is referred to for its dumb cane (dumb meaning incapable of speaking, do you see? ).

As with humans like a human, they’ll experience painful lips, mouths and throat. They’ll begin to behave in a similar way, constantly drooling and drinking a lot as well.

The lips and mouths of their patients may be swollen and red. It is possible that they will start vomiting.

However, it is highly unlikely that it would cause death to a dog or cat. It is likely that after the reaction is bad the pet will cease eating.
