Scientific evaluation and toxicological breakdown of Mountain Laurel

Mountain Laurel (*Kalmia latifolia*) is highly toxic to dogs, cats, horses, and livestock. It contains grayanotoxins, the same toxic compound found in Rhododendrons and Azaleas. Grayanotoxins bind to cell membranes and prevent normal nerve and muscle function. Ingestion of even a few leaves can cause excessive salivation, vomiting, diarrhea, severe muscle weakness, depression, slow heart rate, hypotension, loss of coordination, paralysis, seizures, coma, and death. Emergency veterinary intervention is required immediately.
