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).

Mountain laurel thrives in well-draining, acidic soil with a pH ranging from 5.0 to 5.5. Use a soil pH testing kit -- available at garden centers or home improvement stores -- to test your soil. If the soil in the planting area is higher than 5.5, mix 1 to 2 inches of sphagnum peat moss into the soil's top 6 inches.
