Is Schefflera Poisonous to Humans?

Schefflera houseplants are a popular choice for homes and offices due to their attractive, lush foliage. However, some people wonder – is Schefflera poisonous to humans? The answer is yes, Schefflera plants contain toxins that can cause irritation or illness if ingested. But with proper handling, these tropical plants can be safely enjoyed indoors.

Understanding Schefflera Toxicity

Schefflera is a genus of flowering plants in the Araliaceae family, comprising over 800 species. Some of the most common Schefflera houseplants include:

• Schefflera actinophylla (Octopus tree)
• Schefflera arboricola (Dwarf umbrella tree)
• Schefflera elegans (Umbrella tree)

These tropical plants contain calcium oxalate crystals in their leaves, stems and roots. When skin contacts the sap, it can cause mild dermatitis. If ingested, the oxalate crystals can irritate the lips, mouth and throat. Larger quantities can lead to more severe reactions.

Consuming the leaves, stems or roots can also cause:

• Numbness or burning sensation in the mouth
• Swelling of the lips, tongue and throat
• Difficulty swallowing
• Vomiting
• Diarrhea
• Dilated pupils
• Irregular heartbeat

The toxic principles are found throughout the plant, including the sap, leaves, stems, bark and roots. Both humans and animals are susceptible.

Risks to Humans

For humans, the greatest risk is oral ingestion from chewing or eating the plant parts Children sometimes put leaves, stems or berries in their mouth out of curiosity

When pruning or repotting Schefflera houseplants sap may come into contact with the skin and eyes. This can cause irritation redness, swelling or itching.

Washing the affected area with soap and water can help treat topical exposures. Rinsing the eyes with clean water may relieve ocular irritation

Severe reactions are rare in humans, but large ingestions can be dangerous. Seek medical care if poisoning symptoms persist or worsen.

Poisonous Parts of the Schefflera Houseplant

All parts of the Schefflera plant contain the toxic calcium oxalate crystals. The highest concentrations are typically in:

• Leaves
• Stems
• Bark
• Roots
• Berries (on some Schefflera varieties)

Sap from stems or leaves can cause skin irritation. Ingesting any part of the plant may lead to more severe reactions affecting the mouth, throat, stomach and cardiovascular system in humans.

Schefflera Toxicity in Pets

Dogs and cats are especially sensitive to Schefflera plants. Pets may chew on houseplants when bored or seek out unfamiliar plants outdoors.

Ingesting Schefflera can cause irritation and swelling of the lips, tongue, mouth and throat. Additional symptoms may include:

• Drooling
• Difficulty swallowing
• Vomiting
• Diarrhea
• Loss of appetite
• Depression

If a pet consumes a large amount of Schefflera plant parts, they are at risk for dangerously low blood pressure, dilated pupils, seizures, coma or death without swift veterinary treatment.

Preventing Schefflera Poisoning

Follow these tips to keep Schefflera houseplants safely out of reach:

• Place pots on high shelves or plant stands away from pets and children.
• Keep plants away from cribs, playpens, and play areas.
• Supervise young children and pets around houseplants.
• Wear gloves when pruning or repotting to avoid skin irritation.
• Wash hands after handling Schefflera plants.
