Allergy Facts
The grass family is probably the most important plant family in the world. Grasses are used extensively in landscaping urban and suburban areas, are the providers of almost all cereal crops, and are the principal providers of sugar. Domesticated and wild animals graze on grasses. Furthermore, grasses provide building materials in much of the world (thatch, bamboo, etc.), and millions -- probably billions -- of dollars are spent to treat allergies caused by grass pollen.
