Immunoglobulin E (IgE) is an antibody that is produced by the body's immune system in response to a perceived threat. It is one of five classes of immunoglobulins and is normally present in the blood in very small amounts.
HOWEVER, there are several related plants, also called Laurel, that do contain cyanide and other poisons. For example, the leaves and berries of Cherry Laurel (Prunus caroliniana laurocerasus) contain a chemical known as amygdalin, which is broken down to release cyanide (see below).Mountain Laurel (Kalmia latifolia) contains chemicals called andromedotoxin (grayanotoxin) asebotoxin and arbutin, which are toxic.or example, the leaves and berries of Cherry Laurel (Prunus caroliniana laurocerasus) contain a chemical known as amygdalin, which is broken down to release cyanide (see below).

Laurel toxicity occurs following ingestion of leaves, stems, or flowers from the laurel shrub. Hydrogen cyanide poisoning, the toxic ingredient, combines with hemoglobin and oxygen to prevents oxygen from being distributed to the cells.Systemic poisoning often results in poisoning of the heart muscle.ll types of laurel are toxic to horses, with the severity of the reaction based on the health of the horse. The age and size of the horse are also components of the type of reaction that can be experienced.
