Allergy to pollen - cause of hay fever

Pollen is wind-pollinated plants - the most serious hay fever trigger mechanism.Tiny grains released into the air by trees, grasses and weeds for the fertilization of other plants, are able to penetrate through the epithelium of the nasal mucosa

and into the bloodstream.

wind- blown pollen can spread over many kilometers, and the more it is, the more people will experience "the joys of" hay fever.

number of allergens in the air is directly proportional to the amount of pollen.Intensity of the allergic reactions are generally higher in a dry windy, rainy days, in contrast, the amount of pollen in the air is reduced, because the rain washes allergens.

  3. weeds (eg ragweed, wormwood), which have the most pronounced allergenic activity.

Here are some of the biggest culprits of spring allergies.

Trees: alder, ash, aspen, beech, ash-leaved maple, cottonwood, cypress, elm, hickory, juniper, maple, mulberry, oak, olive, palm, pine, poplar, sycamore, willow.
