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).

1 The attached cyanide ion inhibits the enzyme, thus causing cell death. The shrub cherry laurel is common in most parts of the UK and Europe. Its leaves contain cyanogenic glycosides, molecules comprising a sugar residue attached to a cyanide-containing non-carbohydrate residue.When these compounds are broken down by enzymes they release HCN.atural cyanide compounds are also found in apricot stones, cherry pips, peach and plum stones, corn, chickpeas, cashews and almonds. The Romans and Egyptians knew this all too well and extracted the prussic acid (hydrogen cyanide) from peach stones to use as a poison. Cherry laurel leaves contain deadly cyanide.
