An Allergy is a sensitivity or specific reaction to something inhaled, swallowed, or something that comes in contact with the skin. Allergic substances are called allergens. When an allergen is absorbed into the body, the blood produces antibodies. The antibodies react with the allergens to produce histamines.
Histamines cause inflammation in the nose, eyes, lungs, skin and digestive system, etc.
