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).

Apple seeds contain amygdalin, a substance that releases cyanide into the blood stream when chewed and digested. When comparing the amount of cyanide present in apple seeds with the amount needed to induce death, apple seeds in small amounts do not contain enough cyanide to cause harm.any compounds that contain cyanide â called cyanoglycosides â are found in nature, often in fruit seeds. Amygdalin is one of these. Apple seeds have a strong outer layer that is resistant to digestive juices.
