Steps to take if an incident has occurred

 

In the case of a Small Child:

  • Remove from the Mouth: Immediately take out any plant material from the child’s mouth. Use tweezers or forceps, but be careful not to injure the oral cavity.
  • Do Not Induce Vomiting: It is not recommended to induce vomiting, as this may worsen the situation, especially with certain plants.
  • Call Poison Control or a Doctor: Call your local poison control center or a doctor immediately and follow their instructions. Clearly explain which plant was ingested!
  • Call an Ambulance: If the child exhibits severe symptoms like intense vomiting or difficulty breathing, call an ambulance immediately.

 In the case of a Pet:

  • Do Not Ignore Symptoms: Monitor the pet and note any symptoms, including vomiting, diarrhea, tremors, or any unusual behavior.
  • Retrieve the Plant: If possible, bring the plant that the pet consumed to aid the veterinarian in identifying the toxic substances.
  • Call the Veterinarian or Poison Control for Pets: Call the veterinarian or your local pet poison control center immediately and follow their instructions. Clearly state the type of plant involved, if known.
  • Avoid Inducing Vomiting: Do not attempt to induce vomiting in the pet unless directed by the veterinarian, as it may cause additional harm in some cases.
  • Follow the Veterinarian’s Instructions: Follow the veterinarian’s instructions precisely, including necessary examinations and treatments.

It is crucial to seek professional help as soon as possible, whether it’s for a child or a pet. In cases of poisoning, fast action can help minimize damage and increase the chances of recovery.

How can trouble be prevented?

You don’t have to throw out any poisonous houseplant right now, you just need to handle it more carefully. What does this mean in practice?

 

  • Find a location for the plant where small children or pets cannot reach it under any circumstances.
  • Always use protective gloves when planting, transplanting, propagating, or pruning the plant.
  • If you touch the plant with bare hands, always wash your hands thoroughly.

Conclusion

These plants can pose dangers, so it’s crucial to keep them out of reach of children and pets and ensure they are placed in a secure location. If possible, keep other indoor plants in the house that are non-toxic, such as Tillandsia, Adiantum, or Platycerum.

Finally, remember that sharing your home with a small child or a pet doesn’t mean you must give up your love of indoor plants. However, it’s important to choose them carefully so that everyone can enjoy the beauty of the plants safely.
