Silver Birch pollen becomes airborne in early spring (March-April) and may cause a rash in addition to hay fever symptoms. In addition, people with silver birch pollen often suffer from "cross-reactivity". Up to 60% of those who suffer from it will get a tingling sensation in their lips and tongue when eating an apple.

The immune system identifies the birch and apple allergens as being the same! Other "cross-reactivity" reactions can also occur with parsnip, potato, carrot and hazelnut.


Cedar

Locations: Pacific Northwest, Southwest, South

From February to late May, Oaks produce an enormous amount of pollen. Oak Allergy sufferers experience the worst symptoms during mid April. Oaks are easily identifiable by the "fruit" they produce: acorns.

If Oak pollen is present in the air, your car will often take on a smudged and yellow hue from the accumulation of pollen.




Ash

Locations: All of USA

Ash are large, native, decidious trees that produce copious amounts of potent pollen. Various ash species are hardy in almost any zone.

Ash trees are easy to identify by their oar-shaped helicopter seeds, which spin rapidly as they descend to the ground.

Ash trees tend to have a relatively short pollinating season of approximately two weeks. Ash tree pollination tends to peak during late March or early April during the same time that Birch pollen is present.
