Anecdotal evidence suggests that asthma and hayfever are possible following exposure to pollen from this tree; however, few specific studies on this have been reported to date.
Occupational asthma, lung function deficits, and elevated levels of respiratory symptoms in workers exposed to the wood dust have been demonstrated (1).
A 20-year-old man who had had flexural atopic eczema until 11 years of age, developed facial eczema and swelling 2 months after working at a sawmill as a forklift operator with fresh-sawn Finnish pine (Pinus sylvestris), Spruce (Picea abies) and European white birch (Betula pendula) timber. Patch testing was positive to Myroxylon pereirae resin, colophonium, abietic acid, fragrance mix, pine saw- dust and spruce sawdust (2).
In a study evaluating the impact of different trees on asthma, and the association between daily hospitalizations for asthma and daily concentrations of different tree pollens in 10 large Canadian cities, found an increase in daily tree pollen concentration, and percent increases in daily hospitalization for asthma were 2.45% for the group containing Pinaceae (Pine, Fir, Spruce) (3).
Major aeroallergens in Anchorage, Alaska, are Birch, Alder, Poplar, Spruce, Grass pollen and Cladosporium (4). Pollen from Picea spp. has been reported to be a significant airborne pollen in Zagreb, Croatia (5).
Occupational allergic contact dermatitis (7-8).
Plasters made from Spruce balsam may cause redness, itching papules, and/or sensitive skin, even pustules and ulcers (5).
No allergens from this plant have yet been characterised.
An extensive cross-reactivity among the different individual species of the genus could be expected as well as to a certain degree between members of the family Pinaceae (9).
