Sycamore

Sycamore is easily recognized by its maple-like foliage. It is often found as a means of shade in parks and/or as an avenue tree in cities. The height of growth can reach up to 45 meters. The flowering catkins grow to about 6 to 8 inches tall. The fruit is spherical and grows to about 3 centimeters.

In Germany, the sycamore pollen allergy is one of the rarer pollen allergies. It is only in Spain and in the south of France, where the pollen load is higher and the Only in Spain and in the south of France, where the pollen load is higher, that the sycamore plays a role as an allergy trigger. The main allergen is known as Pla a 1.

Pollen season

The flowers of the sycamore tree appear together with foliage in May. The heavily pruned sycamore trees, which are often seen in cities, flower much less.

Possible cross reactions

Cross-reactions to profilin or polcalcin may be present. Profilins are proteins and are found in all pollen and almost all plant foods (such as fruits, vegetables, nuts, grains). Polcalcins, on the other hand, are only found in pollen. Approximately 5 to 15 % of pollen allergy sufferers are affected by this.
