Mountain Laurel and Sheep Laurel (K. angustifolia) are part of the Ericaceae family. This plant is also called “Sheepkill” (emphasizing just how toxic it is to grazing animals also), and is commonly found in pastures and clearings. Certain types of laurel contain diterpenoids (grayanotoxins). Ingestion will disrupt sodium channels affecting the skeletal and cardiac muscle producing vomiting, excessive drooling, diarrhea, arrhythmias, tremors, coma, and death.
