| Allergology: |
Although approx. 30% of pollinosis sufferers are sensitized against plantain pollen, the clinical relevance of this polinosis type is estimated to be low. The cross-reactivity within the plant family is very high. An antigen community with botanically not related species is not known to exist. Usually polyvaltently sensitized plantain allergy sufferers experience a co-sensitization with other common pollen allergens. A monovalent sensitization against plantain pollen has so far not been documented.
