The Rhaphidophora hayi plant is considered toxic to both humans and pets. Calcium oxalate crystals are present in every component of the hayi Rhaphidophora plant. For this reason, you should keep your shingle plant out of reach. When repotting or propagating, you should wear gloves as skin irritation might occur. Ingestion has far more serious complications. Oral irritation occurs, followed by mouth and throat swelling. If your child has difficulty breathing, please seek emergency care and take the plant sample if you are going to the ER. Rhaphidophora poisoning in pets manifests in excess drooling, vomiting, and loss of appetite. As soon as you notice any of the signs, please contact the vet.
