Houseplants are not only for ornamental purposes, but they also add value to our homes. Some are known for their purifying abilities, while others may be edible or even medicinal. Living in Asia, we love filling our homes with beautiful indoor houseplants for these reasons. However, are you aware of which of these are poisonous plants to humans – especially to our curious babies and toddlers who love putting things in their mouths?
These poisonous plants that we’re going to tell you about can be quite harmful to children and sometimes even pets.
Such plants can poison your little ones or even your beloved pets if they:
- Touch their leaves or lick or swallow them
- Ingest blossoms, berries and roots of plants
- Have skin contact with juices or sap
- Eat plant soil accidentally or on purpose
- Drink water from the plant tray
Because we have your safety at heart, remember these seven poisonous plants to humans, and avoid buying them the next time you go indoor plant shopping.
