Background Pine pollen has long been considered a nonallergenic pollen. Alternata Fumagatus Herbarum Mustard Seed Rape Seed Sunflower Seed Broccoli Cabbage Cauliflower Peach Olive Tree Gramine ae Pollen. The aim of this study was to describe the main allergenic bands of Pinus radiata PR and its crossreactivity with other pine species other conifers and grass pollen.

Below are common food families. Allergy to other trees and herbs. Cross reactivity would be expected within the genus but not outside of Casuarinaceae family.

Allergy to one member of a food family often extends to other members. Pine pollen should be considered as a potential allergenic pollen especially where this pollen is abundant. Banana cantaloupe and watermelon foods Food Families Foods can be grouped into families on the basis of similar molecular structures.

What are the reactions to rosin allergy. Rabbit antisera has confirmed. The families of the Fagales order here.

These are panallergens commonly associated with tree nuts peanuts legumes and seeds. These data confirm the existence of food allergy induced by pine nuts. A partial cross-reactivity could be seen between pine and grass pollens only in patients also sensitized to L.

By cross reactivity is implied having allergies to similar foods within a specific food group. IgE cross-reactivity between cashew and pistachio nut is well described. Approximately 12 of people who are allergic to one.

Cross-reactivity Cross-reactivity can be expected to roughly follow botanical relationships. A cross reaction may occur. The large size of the grain and its low levels of proteins are the main reasons invoked to explain this low allergenicity.

Hormonal disruptions in the body. This sensitization to pine nuts developed with no symptoms of pine pollinosis. Reactions to contact with rosin in an allergic individual include acute allergic contact dermatitis and difficulty breathing.
