CYPRESS POLLEN ALLERGY
Most cypress trees are in the Cupressus genus of plants, but Japanese cypress is in the Chamaecyparis genus of trees.
There are 3 types of cypress trees defined by the WHO (World Health Organization), the allergens associates with this pollen include pectate lyase and polygalacturonase. Common cypress pollen also contains thaumatins and gibberellin-regulated proteins.
Cypress trees release their pollen throughout the year, depending on the species.
An allergy to cypress pollen is strongly associated with seasonal allergic rhinitis (hayfever).
An cypress pollen allergy is also linked to asthma, rhinoconjunctivitis and atopic dermatitis.
Cypress sap contains carvacrol, terpenes and sesquiterpenes.
Pectate lyase proteins are also found in ragweed, wormwood, cedar, sunflower and juniper pollens. Pectate lyase is also a food allergen in almonds
and in penicillin.
Polygalacturonase is also found in cedar, olive pollen, grass pollens, plane trees and saltwort. Endo-polygalacturonase is a food allergen in papaya
are found in olive and cedar pollen, but are usually associated with food allergies. Food containing thaumatins include kiwi, chilli, apple, banana, cherry and peach.
are found in cedar and cypress pollen and are more commonly associated with food. Food containing gibberellins include chilli, orange, cherry, apricot, peach and pomegranate.
