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).

Dangers: Looks similar to the very poisonous cherry laurel. The leaves of cherry laurel smell like cherry/cyanide and have toothed edges while bay laurel leaves have smooth edges and smell like Italian seasoning.Young tree. Leaves closeup (Bay Laurel leaves have smooth edges). Nuts. Teeth (pointy bits along edge of leaves) + cyanide/cherry smell = poisonous cherry laurel.he leaves of cherry laurel smell like cherry/cyanide and have toothed edges while bay laurel leaves have smooth edges and smell like Italian seasoning.
