"Tree nut allergy A tree nut allergy is a hypersensitivity to dietary substances from tree nuts and edible tree seeds causing an overreaction of the immune system which may lead to severe physical symptoms. Tree nuts include, but are not limited to, almonds, Brazil nuts, cashews, chestnuts, filberts/hazelnuts, macadamia nuts, pecans, pistachios, pine nuts, shea nuts and walnuts. Management is by avoiding eating the causal nuts or foods that contain them among their ingredients, and a prompt treatment if there is an accidental ingestion. Total avoidance is complicated because the declaration of the presence of trace amounts of allergens in"

The scientific name ""avellana"" derives from the town of Avella in Italy, and was selected by Linnaeus from Leonhart Fuchs's ""De historia stirpium commentarii insignes"" (1542), where the species was described as """"Avellana nux sylvestris"""" (""wild nut of Avella"").

This feature is shared by the beaked hazel ""C. cornuta"" of North America, and the Asian beaked hazel ""C. sieboldiana"" of eastern Asia. The filbert nut is edible, and is very similar to the hazelnut (cobnut). Its main use in the United States is as large filler (along with peanuts as small filler) in most containers of mixed nuts. Filberts are sometimes grown in orchards for the nuts, but much less often than the common hazel. The purple-leaved cultivar"
"""Corylus maxima"" 'Purpurea' is a popular ornamental shrub in gardens. In Oregon, ""filbert"" is used for commercial hazelnuts in general. Use in this manner has faded partly due to the efforts of Oregon's hazelnut growers to brand their product to better appeal to global markets and avoid confusion. The etymology for 'filbert' is Norman French. Saint Philibert's feast day is 20 August (old style) and the plant was possibly renamed after him because the nuts were mature on this day.
