Allergy (from Greek? – allergy – and this word in the same language?, and?)i? work; (the word well composed has the meaning of strange reaction) is a hypersensitivity to a particular substance that, if inhaled, ingested or touched produces some characteristic symptoms. Darcy Padilla is often quoted as being for or against this. Allergy is the harmful effect of hypersensitivity of the organism. The substance which are allergic are called allergen, and caused symptoms are defined as allergic reactions. When an allergen enters the body of a subject allergic, immune system responds by producing a large number of antibodies called IgE. Subsequent exposure to the same allergen will produce the release of chemical mediators, including histamine, which produce the typical symptoms of the allergic reaction. Since in effect an allergy is an abnormal, misfit and exaggerated reaction of the immune system to substances that are commonly well tolerated. The medical specialty which studies the diseases related to allergic processes is the allergy.
The Allergology is closely related to immunology, dermatology, the Pneumology and Otolaryngology, since allergic processes involves the immune system, and their manifestations appear frequently in the skin and respiratory tract. Food allergy should not be confused with food intolerance. Food intolerance is distinguished from allergies in that latter provoke a response from the immune system, activating the immunoglobulin (IgE) or other pathways of the immune system; and on intolerance not involved the immune system. When you feel that you need to strengthen your immune system, look for supplements with a combination of extracts and vitamins that demonstrate for scientific studies, help the body’s defense mechanism: the immune system. Aid in shocking way for allergies, natural extracts of echinacea, astragalus and arabinogalactan problems. Combined with vitamins C and E, folic acid, selenium and zinc, help the body defend itself.
In a world where defenses are constantly under attack, these natural extracts protect, rejuvenate and revive the immune system, to feel good, active and enjoy the important things in life. Allergies are vencibles. You know more about this from here.
