In severe cases, anaphylaxis with angioedema, bronchitis and hypotension are manifested and symptoms may sometime recur 1-8 hours after the initial symptoms have resolved.
In both USA and Canada, it is the official position that the tree nuts that must be avoided most strenuously and vigilantly are almonds, Brazil nuts, cashew nuts, macadamia nuts, pistachio nuts, pecans, hazelnuts, pine nuts and walnuts.
Those with allergies to tree nuts should be aware that these nuts can pop up in the most unusual places, such as barbecue sauces, flavored coffees and alcoholic beverages.
