Calathea plants, known for their striking foliage and vibrant patterns, are popular choices for indoor greenery. Many plant enthusiasts, especially those with pets or young children, often wonder about the safety of these attractive houseplants. It is reassuring to know that Calathea species are generally considered non-toxic to humans and common household pets.
Calathea Toxicity Status
Calathea plants are classified as non-toxic, meaning they do not contain harmful compounds that cause severe systemic poisoning or lead to serious illness or death upon ingestion. The American Society for the Prevention of Cruelty to Animals (ASPCA) officially lists Calathea species (Calathea spp.) as non-toxic to dogs, cats, and horses, providing a reliable reference for pet owners. This classification applies to all varieties of Calathea.
The absence of compounds like calcium oxalate crystals, found in many irritating plants, contributes to their non-toxic status. Unlike some other popular houseplants that contain toxins causing symptoms such as vomiting or diarrhea, Calatheas do not pose such risks. While not a food source, they are not harmful.
Understanding Potential Mild Reactions
Despite their non-toxic classification, consuming any plant material, including Calathea, can sometimes lead to mild, non-life-threatening reactions. This typically manifests as minor gastrointestinal upset. Symptoms such as vomiting, diarrhea, or a general upset stomach can occur in sensitive individuals or if a large quantity of plant material is ingested.
These reactions are generally due to the indigestible nature of the plant’s fibrous leaves rather than toxic compounds. This can cause temporary stomach discomfort. It is important to distinguish these transient symptoms from the more severe effects associated with actual poisoning.
What to Do After Ingestion
If a pet or child ingests Calathea plant material, monitor them for any symptoms. While severe health effects are unlikely due to the plant’s non-toxic nature, observing their behavior for changes is a sensible approach. Symptoms like drooling, vomiting, or changes in appetite might indicate mild discomfort.
If a very large quantity was consumed, or if symptoms are severe, persistent, or cause distress, contact a veterinarian or a poison control center. For children, the national poison information center can be reached at 1-800-222-1222. In cases of choking or difficulty breathing, immediate emergency medical attention is necessary. To prevent accidental ingestion, keeping houseplants out of reach of curious pets and small children remains a good practice, regardless of the plant’s toxicity status.
