Seasonal Allergies and Complementary Health Practices

Seasonal allergies, also called “hay fever,” are a common chronic medical problem. At least 17.7 million American adults (7.8 percent of the adult population) and 7 million children (about 9 percent of children) have seasonal allergies.
People manage seasonal allergies by taking medication, avoiding exposure to the substances that trigger their allergic reactions, having a series of “allergy shots” (a form of immunotherapy) or using various complementary approaches. According to the 2007 National Health Interview Survey, “respiratory allergy” is among the 15 conditions for which children in the United States use complementary approaches most frequently. This issue of the Digest provides information on what the science says about several complementary health approaches for seasonal allergies, such as saline nasal irrigation, butterbur, honey, acupuncture, and other practices.
