Their larger size and ability to selectively graze around the plant likely protect them from consuming harmful amounts.

However, as with any plant, ingestion of large quantities by any animal could potentially lead to gastrointestinal upset due to its high tannin content. Thus, it's still essential to ensure adequate grazing options and monitor animals that may have limited diet choices.

Mountain Laurel's Use in Folk Medicine

While some of these uses have a basis in the plant's chemistry, and there's potential for future research, current medical science generally does not support the use of mountain laurel for treating major diseases. However, it's crucial to note that these traditional uses also contribute to the misunderstanding of the plant's toxicity.
