The Common Hazel (Corylus avellana) is a species of hazel native to Europe and Asia. The fruit is a nut, produced in clusters of one to five together, each hazelnut held in a short leafy involucre ('husk') which encloses about three quarters of the nut. The nut is roughly spherical to oval, 15-25 mm long and 12-20 mm broad, yellow-brown with a pale scar at the base. The nut falls out of the involucre when ripe, about 7-8 months after pollination. Hazelnuts (Corylus avellana) are among the common tree nuts that lead to allergic reactions. They can be eaten as in-shell nuts, however, the majority is cracked, and the kernels are sold to candy makers, bakers and other food processors. Skin reactions are the most common type of food allergy reactions. They can take the form of itchy, red, bumpy rashes (hives); eczema; or redness and swelling around the mouth or face. A rash can happen when a nut or peanut comes in contact with the skin, even without eating it. Hazelnut allergy is one of the most common tree nut allergies. Hazelnuts, which also are called filbert nuts and cobnuts, look a bit like acorns when they're in the shell. These nuts, like other types of tree nuts, can cause food allergy symptoms that range from mild to severe. If you have an allergy to hazelnuts, symptoms can occur within two hours of consuming hazelnuts or food containing them. These symptoms may include: hives or eczema on your skin allergic conjunctivitis in your eyes, nausea, abdominal pain, vomiting or diarrhea, wheezing, coughing or a runny nose, swelling of lips, tongue, or face (known as angioedema) anaphylaxis, which is a severe allergic reaction that requires immediate medical care. (OAS) is a form of food allergy in which people who are sensitive to specific types of pollen also react to certain foods that are related to those types of pollen. In the case of hazelnuts, many people with birch pollen allergies also react to hazelnuts. The pollen from birch trees and hazelnuts contain allergens that are related, and so your body reacts to both. Symptoms of hazelnut oral allergy syndrome are usually fairly mild, and are confined to tingling, itching or swelling of the lips, tongue, and throat. These symptoms may be treated with an over-the-counter antihistamine such as Benadryl. After taking an antihistamine, a person with this condition should be monitored for the next few hours to make sure that more serious allergic symptoms do not develop. Occasionally, some people with oral allergy syndrome have more severe reactions that may include rashes, delayed gastrointestinal symptoms such as abdominal cramps and diarrhea, or, very rarely, the serious allergic reaction known as anaphylaxis.
