Use saline drops. Squirt a salt-water or saline solution up your nose once or twice a day using a bottle with an angled tip to rid nasal passages of residual pollen.

Try acupuncture. Results are preliminary, but a handful of studies have found that acupuncture can be effective at reducing seasonal allergy symptoms, according to a review published in the 2006 edition of Current Opinion in Allergy and Clinical Immunology.

Change your diet. Some foods, particularly fruits, have the same allergens in them as tree pollens. Therefore some people who are allergic to tree pollens may have symptoms, such as tingling in the mouth, when they eat certain fruits. This is called oral allergy syndrome. Fruits this can occur with include apples, pears, and cantaloupes. Peeling or cooking the fruit usually prevents the reaction.
