Allergic Cascade

The immune system is very specific and goal oriented. Although you may be allergic to a number of substances, allergic reactions are directed at specific allergens. For example, you may be allergic to Bermuda grass, but not oysters. At times, however, two or more foreign substances might appear similar in nature to the immune system, which may mistake one for the other and react to both.
