They are known under the name Ambrosia, ragweed and ragweed and the number of those who actually want to have absolutely nothing to do with it is growing from year to year. The plant, originally from North America, continues to spread throughout Europe and is one of the flora's strongest allergy triggers. Starting at 11 pollen per cubic meter, there is a pronounced strain, in contrast to, for example, grass pollen, where more than 50 pollen per cubic meter have to fly around to be described as a heavy burden. In addition, around 80 percent of allergy sufferers react negatively to ambrosia. And if you have not had anything to do with allergies before, the plant is often the cause of hypersensitivity to contact or inhale. In contrast to other pollen that make us happy in the spring, the Ambrosia flowers relatively late from July to October, with the main load being in August and September. Thus, the pollen season and, so to speak, the burden is further extended.
- runny or stuffy nose
- irritated and swollen eyes
- a headache
- Respiratory impairment up to asthma
Very often, an allergy to ambrosia can also lead to cross-allergies. For example, on parsley, chives, arnica, chamomile, celery, pepper, sunflower and more.
One can afford its small portion that the plant does not spread even further: If you discover the plant – it is particularly often to be seen at bird feed places, since bird food was often contaminated with seeds – this should be pulled out before the bloom and into the remaining waste – not organic waste! – to be thrown. A use of gloves is recommended. If the plant already blooms, the removal should not be done by an allergic person or an allergic person or ideally with a mask. Characteristics in contrast to the similar-looking mugwort:
Leaves: fine with green (not silvery) underside
Stem: green to reddish and hairy (not brown and smooth)
