| Allergology: |
A positive reaction to rumex pollen is detectable for a substantial percent of pollinosis sufferers (5 - 30%). However, a monovalent sensitization has so far not been described. A rumex pollen allergy is hard to ascertain anamnetically because of the overlap in blow seasons of grass and sorrel pollen. Cross-reactions to cultivated types of buckwheat (Fagopyrum) and rhubarb (Rheum) are assumed to exist due to the close genetic relationship.
