In the present text, herbal varieties are listed whose pollen is of allergy-relevant importance (see also tree pollen, grass pollen and cereal pollen; see also cross-reaction). So far > 35 allergens from different herbs have been analysed. Since herbs belong to different botanical groups, the allergen spectrum is different.

Common allergy-causing herbs in Europe:

Mugwort: Together with ribwort plantain (Pla l 1) the most common allergenic herb in Germany. Art v 1, which belongs to the defensin-like protein group, is the major allergen of Artemisia vulgaris. The pollen fly from July to September; pollen size: 18 to 26 µm.

Plantain: Common allergen. Plantain blooms between May and October. Pollen size: 29-40 µm. Cross-allergies are not known.

Goosefoot: relatively rarely causes allergies. The pollen fly between July and September. Size: 19-30 µm. Cross-allergies with other herbs are rare. The major allergen Che a 1 belongs to the ole-e1-like proteins.

Ragweed: Ragweed pollen contains aggressive allergens, which are among the most important allergy triggers in North America. Amb a 1, a pectylase, is the dominant allergen in ragweed pollen with a sensitization rate of >95%. The pollen flies between August and October. Size: 18-20 µm.

Sorrel: Common trigger of allergic reactions. The pollen fly between May and August. Size: 21-33 µm. No known cross allergies.

Amaranth: Pollen of the Chenopodiaceae-Amaranthaceae are mainly found in the warmer dry zones of the earth. Amaranthus species are now spreading mainly in southern Europe. According to a Spanish study (Vaquero C et al. 2013) their pollen is highly sensitized to polliosis. Major allergen is the profilin Ama r 2.

General information

There are no reliable data on the sensitisation frequencies of herbal pollen. The most frequent sensitization is found against plan l1, the main allergen of ribwort . Prevalences of sensitization to species v 1 (main allergen of mugwort) were found in 4.4% of randomly selected adult individuals. Against Amb a 1 (main allergen of ragweed) at 0.7%. However, there are considerable geographical differences in the sensitization spectra.
