More than 35 million people suffer from allergies in the United States. An allergy is an reaction to a very small amount of a specific substance, very often mold or pollen. People react differently to allergens, but common symptoms include runny nose, watery eyes, and sneezing.

Tree and grass pollens are the most common Southwest Ohio allergens and can be almost impossible to escape. Oak, cedar, mulberry, maple, elm, poplar, box elder and grasses are the most prevalent sources of pollen in Southwest Ohio from late March through mid-July. Ragweed, the most allergenic plant of North America, blooms from August through October. Mold spores are also in full swing all summer and can even be found indoors year-round.
