Pollen allergy, can you still grow flowers?
In the allergy department of the hospital, parents often meet and ask: “Doctor, my child is allergic to pollen, will he not be able to raise flowers at home in the future?” ]
In fact, pollen, which is easy to cause allergy, is not an ornamental flower with fragrant smell and bright color.
Because the pollen of these flowers usually contains nectar, which is sticky, fragrant and sweet, and can attract insects such as bees to help them pollinate, these flowers are called insect matchmaker flowers. Since the pollen cannot be blown away with the wind, most of them will not cause pollen allergy.
It is pollen from trees or weeds that is easy to cause allergy.
The pollen of these plants has no fragrance, no nectar and no sweet taste, so they cannot attract insects to spread. They are mainly spread by wind and are called wind-media flowers. What we usually call pollen allergy is caused by wind-media flowers.
Spring pollen that is easy to cause allergy includes poplar, willow, elm, birch, cypress, etc.
People with pollen allergy should hide when they see these plants.
