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 'NOVITA â¢'. This variety of common laurel is a selection from Rotundifolia and as a result, is very similar to it. There is some evidence that it may be even hardier, tolerating temperatures of -27 C, and so it is becoming more popular on continental Europe where winters are harder than in the UK.arbled White is a variety of Common Laurel with fine white markings on the leaves. It is slower growing that most other varieties of Prunus laurocerasus as it has less chlorophyll in the leaves because of the variegation. Ultimate height 5m (15ft) tall.
