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).

Prunus laurocerasus, cherry laurel. The leaves and fruit pips contain cyanolipids that are capable of releasing cyanide and benzaldehyde. The latter has the characteristic almond smell associated with cyanide.1.5% cyanogenic glycosides are present in the leaves. During maceration, i.e. chewing, this becomes glucose, hydrogen cyanide (prussic acid), and benzaldehyde. Cyanide starves the central nervous system of oxygen and, thus, causes death.The Prunus laurocerasus has enough of the poison in the leaves to be used by entymologists as a way of killing insect specimens without physical damage..5% cyanogenic glycosides are present in the leaves.
