Laurel Plant Toxicity Comparison

Cherry Laurel (Prunus laurocerasus)

• Toxicity: Highly toxic due to cyanogenic glycosides, which release hydrogen cyanide (prussic acid) when ingested. All parts of the plant are toxic, especially the leaves and seeds.
• Symptoms: Abdominal pain, nausea, vomiting, headache, dizziness, and in severe cases, respiratory failure.
• Risk: Particularly dangerous for children and pets due to its attractive berries.

Portuguese Laurel (Prunus lusitanica)

• Toxicity: Also contains cyanogenic glycosides, making it toxic to humans and animals. The leaves and stems are particularly hazardous.
• Symptoms: Similar to Cherry Laurel, with gastrointestinal issues, tremors, and potential neurological symptoms.
• Risk: Highly toxic to dogs, requiring immediate veterinary attention if ingested.

Bay Laurel (Laurus nobilis)

• Toxicity: Contains essential oils that can cause digestive issues if ingested in large quantities. Not as toxic as Cherry or Portuguese Laurel but still poses risks.
• Symptoms: Vomiting, diarrhea, skin irritation, and in severe cases, respiratory problems.
• Risk: More of a concern for pets and young children due to its accessibility and use in cooking.

Mountain Laurel (Kalmia latifolia)

• Toxicity: Highly toxic to humans and animals. All parts of the plant contain grayanotoxins, which can cause severe health issues if ingested.
